All of the 4th grade teachers and students from Cambridge went on a field trip to an art museum. Tickets were $5.50 per teacher and $3.00 for each student. This group paid $29.00 in total. The next month, the same group visited a science museum where the tickets were $22.00 for teachers and $11.50 for students. The group paid $113.00 in total. Find the number of teachers and students on the field trips.
Answer:
Students= 6
Teachers= 2
Step-by-step explanation:
Given: Art museum trip:
Cost of ticket= $5.5 per teacher and $3 per student.
Total amount paid= $29.
Science trip:
Cost of ticket= $22 per teacher and $11.5 per student.
Total amount paid= $113.
Lets assume number of teacher be "x" and number of students be "y".
Now, forming an equation for cost of each trip.
we know, total cost= [tex]cost\ of \ each\ ticket \times numbers\ of\ tickets[/tex]
∴Art museum trip, [tex]5.5x+3y= 29[/tex] ---- 1st equation
Science museum trip, [tex]22x+11.5y= 113[/tex] ---- 2nd equation
Next using elimination method to find number teacher and students
[tex]5.5x+3y= 29\\22x+11.5y= 113[/tex]
Multiplying both side of 1st equation by 4
∴ [tex]22x+12y= 116\\22x+11.5y= 113[/tex]
changing sign of 2nd equation on both side and solving it.
∴ [tex]0.5y= 3[/tex]
Dividing both side by 0.5
[tex]y= \frac{3}{0.5}= 6[/tex]
Hence, number of students on field trip was 6.
Subtituting the value of y in 1st equation to find the number of teachers in field trip.
[tex]5.5x+3y= 29[/tex]
⇒ [tex]5.5x+3\times 6= 29[/tex]
⇒ [tex]5.5x+18= 29[/tex]
Subtracting both side by 18
⇒ [tex]5.5x= 11[/tex]
Dividing both side by 5.5
⇒ [tex]x= \frac{11}{5.5}= 2[/tex]
Hence, there were 2 teachers on field trips.
Justin saves $8 every week. Which equation represents the amount of money Justin has,y, after x number of week?
If Justin saves $8 every week, and x represents the number of weeks, this can be set up as 8x. We are trying to find the amount of money Justin has after x weeks, so y = 8x.
Which is the graph of f(x) = 2(3)x?
Answer:
a
Step-by-step explanation:
if f(x)=y then when x is 1 2(3)^X= 6
Answer:
first graph
Step-by-step explanation:
given: [tex]f(x) = 2(3)^{x}[/tex]
substitute some values for x and see which curves accurately reflect the corresponding y-values:
when x = 0, f(0) = 2(3)^0 = 2(1) = 2
hence the graph must pass through the point (0,2)
We can see from the choices that the 2nd and 4th graphs do not pass through (0,2), so we can eliminate these 2 from consideration
when x = 1, f(1) = 2(3)^1= 2(3) = 6
hence the graph must pass through the point (1,6)
We can see that the 3rd graph does not pass through this point so we can eliminate the 3rd graph also.
Only the 1st graph gives points consistent with the 2 cases above.
what is 4x-2y=8 and y=2x+1 using substitution
Answer:
No Solution
Step-by-step explanation:
4x-2y=8
y=2x+1
Make the first equation into where it says y=.
-2y=-4x+8
y=2x-4
Substitute either equation into the other as y=.
2x+1=2x-4 or 2x-4=2x+1
Switch terms around so they're with their like terms. Make sure it becomes the opposite when switching.
2x-2x=-1-4 or 2x-2x=4+1

The vertex of a parabola is at (8,-1)and its y-interpret is-17. Which function represents the parabola
Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (8, - 1), thus
y = a(x - 8)² - 1
To find a substitute (0, - 17), the coordinates of the y- intercept into the equation.
- 17 = a(0 - 8)² - 1
- 17 = 64a - 1 ( add 1 to both sides )
- 16 = 64a ( divide both sides by 64 )
a = [tex]\frac{-16}{64}[/tex] = - [tex]\frac{1}{4}[/tex]
y = - [tex]\frac{1}{4}[/tex](x - 8)² - 1 → D
A woman traveled 2445.9 miles in 18 hours five minutes what is the average speed of her flight in miles per hour
The average speed is 135.26 miles per hour
Solution:
Given that, woman traveled 2445.9 miles in 18 hours five minutes
To find: Average speed of her flight in miles per hour
Let us first convert 18 hours 5 minutes to hours
We know that,
[tex]1 \text{ minute } = \frac{1}{60} \text{ hour }[/tex]
Therefore,
[tex]5 \text{ minute } = \frac{5}{60} \text{ hour } = 0.083 \text{ hour }[/tex]
Thus we get,
18 hours five minutes = 18 hour + 0.083 hour = 18.083 hour
Given that, distance = 2445.9 miles
Average speed is given by formula:
[tex]Average\ speed = \frac{distance}{time}\\\\Average\ speed = \frac{2445.9}{18.083}\\\\Average\ speed = 135.26[/tex]
Thus average speed is 135.26 miles per hour
To make circular cake boards, a company cuts circles out of plastic squares. The circles are cut as wide as the squares to lessen the amount of wasted material. Use the drop-down menus below to complete statements about the amount of wasted material for circular cake boards with a diameter of d.
The area of the wasted material is given by the difference:____-______
d^2
4d
π(d/2)^2
Answer:
d^2 - π(d/2)^2
Step-by-step explanation:
Since the diameter of the circle is equal to the side of a square (d), that means that we have a circle inscribed in square.
If we draw a square and inscribe a circle in it, all parts of the square outside the circle will be waste, in this particular case.
If we want to find the area of the wasted material we need to subtract the area of the circle from the area of the square.
Area of the circle is:
P1 = πr^2, r being the radius
Since radius is half the diameter, that means that:
P1 = π • (d/2)^2
Area of the square whose side is d is:
P2 = d^2
So, the area of wasted material is:
P = P2 - P1
P = d^2 - π(d/2)^2

Answer: 10 , 11 , 12
Step-by-step explanation:
Let the integers be : x , x + 1 and x + 2
the smallest multiplied by 3 implies 3x
From the first statement
3x = 18 + (x+2)
3x = 18 + x + 2
3x - x = 18 + 2
2x = 20
x = 10
Therefore : the numbers are : 10 , 10 + 1 and 10 + 2
the numbers are : 10 , 11 , 12
Answer:
10,11,12
Step-by-step explanation:
3 consecutive integers...x and x + 1 and x + 2
3x = x + 2 + 18
3x = x + 20
3x - x = 20
2x = 20
x = 20/2
x = 10
x + 1 = 10 + 1 = 11
x + 2 = 10 + 2 = 12
ur numbers are 10, 11, and 12

When solving equations you goal is to get x by itself so
18-6.3x=49.5 (first step would be to minus 18 from each side)
-6.3x=31.5 (18-18=0, 49.5-18=31.5) (now you want to divide each side by -6.3)
x=-5 (-6.3/-6.3=1, 31.5/-6.3=-5)

The model builder has 4 pieces of balsa wood that are 4 cm, 5 cm, 6 cm, and 7 cm in length. How many different combinations of 3 pieces can be used to make triangles without breaking or cutting the pieces? List the combinations as inequalities.
Answer:
4<5<6
4<5<7
4<6<7
5<6<7
since there are 4 pieces of wood, you will have 4 combinations. since the sum of the 2 shortest sides need to be more than the longest side the inequalities above are valid.
Hope this helps!!
Final answer:
Out of the four lengths of wood provided, there are three valid combinations that can form triangles: 4 cm, 5 cm, 6 cm; 4 cm, 6 cm, 7 cm; and 5 cm, 6 cm, 7 cm. These combinations satisfy the Triangle Inequality Theorem, which is necessary for forming triangles.
Explanation:
To determine how many different combinations of 3 pieces of balsa wood can be used to make triangles, we must recall the Triangle Inequality Theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. For the pieces of lengths 4 cm, 5 cm, 6 cm, and 7 cm, we can form the following combinations that satisfy the Triangle Inequality Theorem:
4 cm, 5 cm, 6 cm
4 cm, 6 cm, 7 cm
5 cm, 6 cm, 7 cm
The inequalities for these combinations are as follows:
4 cm + 5 cm > 6 cm
4 cm + 6 cm > 5 cm
5 cm + 6 cm > 4 cm
4 cm + 7 cm > 6 cm
6 cm + 7 cm > 4 cm
5 cm + 7 cm > 6 cm
Each of these combinations is valid as the sum of the lengths of any two pieces is greater than the length of the third piece.

Final answer:
To find the perimeter of the rectangle, calculate the length using the given area and width. Then, apply the perimeter formula P = 2l + 2w. The perimeter is approximately 25.1 feet.
Explanation:
Calculating the Perimeter of a Rectangle
To find the perimeter of a rectangle, you need to know both the width and the length of the rectangle. The perimeter is the total distance around the rectangle, which is the sum of twice the width and twice the length: P = 2l + 2w.
The width of the rectangle is given as 4 1/6 feet. To find the length, we can use the provided area of the rectangle which is 35 square feet. The area of a rectangle is found by multiplying the length by the width: A = l × w. Let's call the length 'l'.
First, convert the width to an improper fraction: 4 1/6 = (4 × 6 + 1)/6 = 25/6 feet. Now set up the equation using the area: 35 = (25/6) × l. Solving for 'l' gives us l = (35 × 6)/25 = 210/25 = 8.4 feet.
Now that we have the length, calculate the perimeter using the equation P = 2l + 2w:
P = 2 × 8.4 + 2 × 4 1/6
P = 16.8 + 2 × 25/6
P = 16.8 + 50/6
P = 16.8 + 8.333...
P = 25.133... feet
Therefore, the perimeter of the rectangle is approximately 25.1 feet when rounded to one decimal place.
how do you estimate 175.32 ÷ 3 =
Answer:
≈ 58
Step-by-step explanation:
Estimation usually means you want an answer good to one or maybe two significant figures. That usually means you want to round the numbers involved to one or two significant figures.
Doing that here transforms the problem to 180/3 = 60, an answer with one significant figure.
You can improve the estimate a bit by recognizing that it is a little high (the numerator is higher than 175.32, but the denominator is the same). Since the numerator is high by about 5, the estimate is high by about 5/3 or a little less than 2. A closer estimate will be 60 - 2 = 58.
_____
The degree to which you refine the estimate will depend on the error requirements you have. Certainly an estimate of 60 is within 10% of the true value, so is "close enough" for many purposes.
To estimate 175.32 by 3, round 175.32 to 175, and divide by 3 to get 58. Since 175 is just under 180, which divides evenly by 3 to give 60, an estimate of 58 is reasonable.
To estimate the division of 175.32 by 3, we can round the numbers to make the calculation easier. First, we round 175.32 to 175 which is very close in value, and 3 remains as it is because it is already a whole number. So, our estimation becomes 175 / 3.
Dividing 175 by 3 gives us 58 as 3 times 58 is 174. We can see that this approximation is just 1 less than our rounded number, so it is a reasonable estimate. Therefore, 175.32 / 3 is approximately 58 when we estimate it without a calculator.
To check our estimation, we can compare it to similar, simple calculations. For example, if we divide 180 by 3, we get 60. Since 175 is slightly less than 180, our estimation of 58 is likely a good approximation for the division of 175.32 by 3.

4) Kent has $14 in his bank account and spent $1,700.
Answer:
Option 1) Kent has $1,700 in his bank account and spends $14 each week.
Step-by-step explanation:
Let x denote the number of weeks.
Option 1: Kent has $1,700 in his bank account and -14x as the negative sign denotes how much amount he spend each week.
Thus, Option 1 is the correct answer.
Option 2: Kent has $1,700 in his bank account and deposits $14 each week.
Writing it as equation, we have, [tex]y=14x+1700[/tex] which is not the expressed linear equation.
Hence, Option 2 is not the correct answer.
Option 3: Kent had $1,700 in his bank account and deposited another $14.
Writing it as equation, we have, [tex]y=14+1700[/tex] which is not the expressed linear equation.
Hence, Option 3 is not the correct answer.
Option 4: Kent has $14 in his bank account and spent $1,700.
Writing it as equation, we have, [tex]y=14-1700[/tex] which is not the expressed linear equation.
Hence, Option 4 is not the correct answer.
Thus, the scenario that matches the linear equation relationship expressed in the equation is Option 1.
The answer is Kent has $1,700 in his bank account and spends $14 each week.

Julio sold candles for three weeks. Let x represent the number of candles he sold the first week. He sold twice the number of candles the second week as he did the first week. In the third week, Julio sold 4 less than the number he sold the first week. Which expression represents the total number of candles Julio sold in the three weeks?
The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.
Step-by-step explanation:
Let,
x be the number of candles sold by Julio in first week.
According to given statement;
Candles sold in first week = x
He sold twice the number of candles the second week as he did the first week.
Candles sold in second week = 2x
In the third week, Julio sold 4 less than the number he sold the first week.
Candles sold in third week = x-4
Total candles sold = First week + Second week + Third week
Total candles sold = x+2x+(x-4)
The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.

The 4th term of an arithmetic sequence is 12 and the 8th term is 36. Find the 17th term of the sequence.
How do you work it out?
Answer: 90
Step-by-step explanation:
The formula for calculating the nth term of a sequence is given as :
[tex]t_{n}[/tex] = a + ( n - d )
Where a is the first term
d is the common difference and
n is the number of terms
This means that the 4th term of an arithmetic sequence will have the formula :
[tex]t_{4}[/tex] = a + 3d
And the 4th term has been given to be , 12 ,substituting into the formula we have
12 = a + 3d .............................. equation 1
Also substituting for the 8th term , we have
36 = a + 7d .............................. equation 2
Combining the two equations , we have
a + 3d = 12 ................... equation 1
a + 7d = 36 ------------ equation 2
Solving the system of linear equation by substitution method , make a the subject of formula from equation 1 , that is
a = 12 - 3d ................... equation 3
substitute a = 12 - 3d into equation 2 , equation 2 then becomes
12 - 3d + 7d = 36
12 + 4d = 36
subtract 12 from both sides
4d = 36 - 12
4d = 24
divide through by 4
d = 6
substitute d = 6 into equation 3 to find the value of a, we have
a = 12 - 3d
a = 12 - 3 ( 6)
a = 12 - 18
a = -6
Therefore , the 17th term of the sequence will be :
[tex]t_{17}[/tex] = a + 16d
[tex]t_{17}[/tex] = -6 + 16 (6)
[tex]t_{17}[/tex] = -6 + 96
[tex]t_{17}[/tex] = 90
Therefore : the 17th term of the sequence is 90

**10-year Term Policy:**
- Annual premium: $240.00
- Semiannual premium (51% of annual): $240.00 * 51% = $122.40
- Quarterly premium (26% of annual): $240.00 * 26% = $62.40
- Monthly premium (9% of annual): $240.00 * 9% = $21.60
**Whole Life Policy:**
- Annual premium: $652.50
- Semiannual premium (51% of annual): $652.50 * 51% = $332.775 (approximately $332.78)
- Quarterly premium (26% of annual): $652.50 * 26% = $169.50
