89

Step-by-step explanation:He bought 89 items because 20 + 3 is 23, 23 + 12 is 35, 35 + 11 is 46, 46 + 24 is 70, and 70 + 11 is 89.

Step-by-step explanation:

Given by question,

(x, y) = (5, 15)

Here, x = 5 and y = 15

To find, the value of [tex]\tan \theta[/tex] = ?

We know that,

[tex]\tan \theta[/tex] = Sope = [tex]\dfrac{y}{x}[/tex]

∴ [tex]\tan \theta[/tex]  = [tex]\dfrac{15}{5}[/tex]

⇒ [tex]\tan \theta[/tex]  = [tex]\dfrac{3}{1}[/tex]

⇒ [tex]\tan \theta[/tex]  = 3

∴ The value of [tex]\tan \theta[/tex] = 3

Thus, the value of [tex]\tan \theta[/tex] is equal to 3.

Answer:

y = [tex]\frac{1}{2}[/tex] x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 6, - 5) and (x₂, y₂ ) = (- 4, - 4)

m = [tex]\frac{-4+5}{-4+6}[/tex] = [tex]\frac{1}{2}[/tex], thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 6, - 5), then

- 5 = - 3 + c ⇒ c = - 5 + 3 = - 2

y = [tex]\frac{1}{2}[/tex] x - 2 ← equation of line

To find the equation of the line through (-6, -5) and (-4, -4), calculate the slope and then apply the point-slope form to yield the line equation y = 1/2x - 2.

The question is about finding the equation of the line that passes through two given points, (-6, -5) and (-4, -4). To do this, we first need to find the slope of the line (m) using the formula: m = (y2 - y1) / (x2 - x1). Plugging in the points, we get m = (-4 + 5) / (-4 + 6) = 1 / 2. Next, we use the point-slope form of a linear equation, y - y1 = m(x - x1), to find the equation. Using point (-6, -5) and the slope 1/2, the equation becomes y + 5 = 1/2(x + 6). Finally, simplifying, we get y = 1/2x - 2 as the completed equation of the line.

The equation according to the given verbal sentence is [tex]\frac{2 t+2}{2 s^{3}}[/tex] (after solving this [tex]\frac{t+1}{s^{3}}[/tex] ).

Step-by-step explanation:

Rewrite the given verbal sentence and so it will be easier to translate.

Given: The quotient of the sum of 2 t and 2 and twice the cube of s

sum of 2 t and 2 can be written as

       2 t + 2

twice the cube of s

      [tex]2 s^{3}[/tex]

Now, combine the above according to the given verbal. The quotient of the sum of 2 t and 2 and twice the cube of s  means,

             2 t + 2  divided by [tex]2 s^{3}[/tex]

Now, the equation would be [tex]\frac{2 t+2}{2 s^{3}}[/tex]

When solving this equation, we get

         [tex]\frac{2(t+1)}{2 s^{3}}=\frac{t+1}{s^{3}}[/tex]

The quotient of the sum of 2t and 2 and twice the cube of s is [tex]\frac{t + 1}{s^3} [/tex].

The given parameters:

The sum of 2t and 2 is written as follows;

sum = 2t + 2

The cube of s is written as follows;

cube = s³

twice the cube of s = 2s³

The quotient of the sum of 2t and 2 and twice the cube of s is calculated as follows;

[tex]= \frac{2t + 2}{2s^3} \\\\ = \frac{2(t + 1)}{2s^3}\\\\ = \frac{t + 1}{s^3} [/tex]

Answer:

you add -8 to 13

Step-by-step explanation:

-8+13=5

p=5

Answer: 5 = p

Step-by-step explanation: To solve the equation -8 = p - 13, notice that the variable is on the right side of the equation,

don't let this throw you off.

To solve for p, we need to get p by itself on the right side of the equation by adding 13 but if we add 13 to the right side of the equation, we also must add 13 to the left side of the equation.

On the right side of the equation, the -13 and + 13 cancel eachother out and we have p. On the left side of the equation, -8 + 13 is 5 so we have 5 = p which is the solution to our equation.

Answer:

Option A, 12/5

Step-by-step explanation:

If sin (theta) < 0 that means that the angle is in either quadrant 3 or 4.

Since cos or x is negative, that makes the angle limited to either 2 or 3.

The only quadrant that matches with those to is quadrant 3.

So, to find out what tan (theta) is, you need to make a graph and draw the line in quadrant 3.

Look at the attached graph

tan (theta) = opposite / adjacent

tan (theta) = -12/-5 = 12/5

Answer = Option A, 12/5

Final answer:

Mrs. Smith will donate $20 for Sam walking 20 miles, illustrating a direct proportional relationship with a constant of proportionality of $1 per mile, which is a simple yet effective example of how constants of proportionality function in everyday scenarios.

Explanation:

In the fundraiser mentioned, Mrs. Smith pledges $1 for each mile walked. If Sam walks 20 miles, Mrs. Smith will donate $20. The constant of proportionality in this problem is $1 per mile.

You can see this relationship as a simple formula: total donation = $1 × number of miles walked. So, if we replace "number of miles walked" with 20, the formula would be total donation = $1 × 20 = $20. This illustrates how the initial pledge creates a directly proportional relationship between the money donated and the miles walked.

The constant of proportionality here is crucial because it tells us how much money will be donated per mile that Sam walks. It is a straightforward example of how constants of proportionality work in real-life scenarios, similar to being paid for each call made in a phone drive or being charged per hour of tutoring.

Final answer:

Wen Ti travels 9.2π feet in one complete spin on the outer edge of the carousel, which has a radius of 4.6ft. The correct option is A.

Explanation:

The question asks how far Wen Ti travels in one spin of the carousel, if she is on the outer edge with a radius of 4.6ft. To find this distance, we use the formula for the circumference of a circle, which is C = 2πr, where r is the radius of the circle. Plugging in the given radius of 4.6ft, we find that Wen Ti travels 2π(4.6) = 9.2π feet in one spin of the carousel.

Answer: vertex

Step-by-step explanation:

Answer:

Vertex. The vertex is the point where two points meet, and the point 12 is where the lines meet.

To find the number of items, x, for which the total daily cost, C, of each machine will be the same, we can set up an equation and solve for x. The number of items x for which the total daily cost C of each machine will be the same is 20. For 20 items produced, the total daily cost per machine is $60.

To find the number of items, x, for which the total daily cost, C, of each machine will be the same, we can set up the following equation:

40 + 1x = 30 + 1.5x

Simplifying, we get:

0.5x = 10

Dividing both sides by 0.5, we find:

x = 20

Therefore, the number of items x for which the total daily cost C of each machine will be the same is 20.

To find the total daily cost per machine for this number of items, we can substitute x = 20 into the equations for each machine:

Machine A: C = 40 + 1(20) = 60

Machine B: C = 30 + 1.5(20) = 60

So, for 20 items produced, the total daily cost per machine is $60.

Final answer:

To calculate the travel time from Lubbock to San Antonio at 60 miles per hour, divide the distance (394 miles) by the speed, resulting in about 7 hours when rounded to the nearest hour.

Explanation:

The question is about calculating the travel time from Lubbock to San Antonio when driving at a speed of 60 miles per hour. Based on the provided chart, the distance between Lubbock and San Antonio is 394 miles. To find the travel time, we use the formula time = distance ÷ speed. Therefore, the travel time is calculated as 394 miles ÷ 60 miles/hour = 6.5667 hours. Rounding this to the nearest hour gives us approximately 7 hours. So, it will take about 7 hours to drive from Lubbock to San Antonio at a speed of 60 miles per hour.

Answer:

x=15

Step-by-step explanation:

This is a simultaneous equation

2x-3y=45 ------------------------------ equation i

x+y=10    -------------------------------equation ii

from equation ii

x+y=10

make x the subject of the matter

we have,

x=10-y

in equation i

substitute x for 10-y

2x-3y=45----------------------i

since x=10-y

we have,

2(10-y) - 3y=45

20-2y=3y=45

collect like terms

-2y-3y=45-20

-5y=25

divide both sides by -5

we have y=-5

substitute y for-5 in equation i

x+y=10

x+-5=10

collect like terms

x=10+5

x=15

therefore

x=15

Answer:

  x = 15

Step-by-step explanation:

Use the second equation to write an expression for y:

x = -5

y = 9

============================================

Work Shown:

Start by solving the second equation for x.

3x = -15

3x/3 = -15/3 .... divide both sides by 3

x = -5

Then plug this into the first equation and isolate y.

6x + 4y = 6

6(-5) + 4y = 6 .... every x replaced with -5

-30 + 4y = 6

-30+4y+30 = 6+30 .... add 30 to both sides

4y = 36

4y/4 = 36/4 .... divide both sides by 4

y = 9
