Periodic tune-ups are important because they

Answers

Periodic tune ups and transmission overhauling according to company’s specifications lengthen the life of the vehicle, avoid the need for expensive maintenances, and avoid unsafe failures. For the duration of a tune-up, you must have your spark plugs, spark provider, distributor cap, and air filter new. The effectiveness of your vehicle should be checked and attuned, and your points should be changed, if your vehicle has them. The law necessitates in furthermost cases that you have an emission test every two years, at the time of record-keeping or at time of sale. It is a respectable awareness to have the smog control constituents checked at the time of a tune-up. Make certain that smog controller devices are together and linked appropriately.

A direct variation function contains the points (–9, –3) and (–12, –4). Which equation represents the function?
y = –3x
y = – x/3

-1/-3
1/3 is the slope of this equation. 
You do not have to go any further to find b or the y-intercept because it appears that b or the y-intercept is 0 in this case. 
y= 1/3x or in other words y= x/3

The number of 1 cent stamps exceed the number of 33 cent stamps by 50. The number of 32 cents was 10 less than twice the number of 33 cents stamps. How many of each kind did she buy?

Answers

x = 1 cent, y = 32 cent, and z = 33 cent

0.01x + 0.32y + 0.33z = 21.80
x = z + 50
y = 2z - 10

0.01(z + 50) + 0.32(2z - 10) + 0.33z = 21.80
0.01z + 0.5 + 0.64z - 3.20 + 0.33z = 21.80
0.98z - 2.7 = 21.8
0.98z = 21.8 + 2.7
0.98z = 24.5
z = 24.5 / 0.98
z = 25 <=== 33 cent stamps

x = z + 50
x = 25 + 50
x = 75 <=== 1 cent stamps

y = 2z - 10
y = 2(25) - 10
y = 50 - 10
y = 40 <== 32 cent stamps


 



Final answer:

Mildred bought 480 1 cent stamps, 410 32 cent stamps, and 520 33 cent stamps.

Explanation:

Let's solve this problem using a system of equations.

Let's use the variables x, y, and z to represent the number of 1 cent stamps, 32 cent stamps, and 33 cent stamps respectively that Mildred bought. We can write the following equations based on the information given:

x + y + z = 2180  (since the total cost was $21.80)

x = z + 50  (since the number of 1 cent stamps exceed the number of 33 cent stamps by 50)

y = 2z - 10  (since the number of 32 cent stamps was 10 less than twice the number of 33 cents stamps)

Let's solve this system of equations:

Substitute the value of x from equation 2 into equation 1: (z + 50) + y + z = 2180Substitute the value of y from equation 3 into equation 1: z + 50 + (2z - 10) + z = 2180Simplify and solve for zSubstitute the value of z into equation 2 to find xSubstitute the value of z into equation 3 to find y

After solving the system of equations, we find that Mildred bought 480 1 cent stamps, 410 32 cent stamps, and 520 33 cent stamps.

Logan county is square. It had a side that is 15.4 miles long. What is the area?

Answers

The area of any rectangle is xy where xy are the dimensions of the rectangle.  A square is just a special rectangle where x=y so it's area is:

A=x^2 where x is its side length, in this case 15.4 miles

A=15.4^2

A=237.16 mi^2
First of all, we know that Logan's County has the shaped of square, and the question states that to find the area of his county. To find the area, we will use Area of square formula.
A=s•s where s represent the side of his county which is 15.4 miles long, so we just beed to do now is substitute s with 15.4
A=s•s
A=15.4•15.4
A=237.16 square miles. As a result, the area of Logan's County is 237.16 square miles. Hope it help!

Answers

The initial value is 4 and the rate of change is -3/4

Answer:

The initial value is 4 and the rate of change is tex]\frac{-3}{4}[/tex]

Step-by-step explanation:

The initial value is the y intercept of the given line.

Y intercept is the point where the graph crosses y axis

y intercept is (0,4) so initial value is 4

Rate of change is the slope

To find rate of change we use formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Pick two points from the graph

(0,4) and (4,1)

Rate of change =  [tex]\frac{1-4}{4-0}=\frac{-3}{4}[/tex]

The population of a type of local dragonfly can be found using an infinite geometric series where a1 = 65 and the common ratio is 1/6. Find the sum of this infinite series that will be the upper limit of this population.

Answers

In mathematics, number sequencing of the same pattern are called progression. There are three types of progression: arithmetic, harmonic and geometric. The pattern in arithmetic is called common difference, while the pattern in geometric is called common ratio. Harmonic progression is just the reciprocal of the arithmetic sequence.

The common ratio is denoted as r. For values of r<1, the sum of the infinite series is equal to

S∞ = A₁/(1-r), where A1 is the first term of the sequence. Substituting A₁=65 and r=1/6:

S∞ = A₁/(1-r) = 65/(1-1/6)
S∞ = 78

shade the region in the xy plane that is described by the inequalities 3x-y-7<0 and x+5y+3>=0

Answers

To solve inequalities algebraically, first, you have to graph the lines disregarding the inequalities for a while.

For line 3x-y-7 <0, let's disregard < first and change it to =, such that 3x-y-7=0. Rearranging, y=3x-7. If you plot this equation, that would be the blue line in the equation. To know which of side of the line is the solution, you substitute a random point into the equality. For example, let's use point (5,20).

3x-y-7<0
3(5)-20-7<0
-12<0, this is true. Therefore, all the space to the left of the blue line is a solution (blue region).

We do the same for the other equation (orange line). Let's use the same point (5,20) to test.

x+5y+3≥0
5+5(20)+3≥0
108≥0, this is true, Therefore, everything above the orange line is a solution (orange region).

The overlapped area of the two shaded regions is presented as green in the picture. This is the exact solution of this system of linear equations.

A restaurant charges $100 to rent its banquet room for an event. It also charges $15 to serve dinner to each quest. Write an equation for the total cost of the banquet room in terms of the number of guests. Define your variables. What is the total cost of the banquet room for 20 guests?

Answers

total cost (t) , number of guests (n)

t = 15n + 100 <== ur equation

for 20 guests...n = 20
t = 15(20) + 100
t = 300 + 100
t = 400 <== cost for 20 guests

Answer:

The total cost function is C (x) = 15x + 100 and the cost of a banquet for 20 guests is $ 400

Step-by-step explanation:

Let's suppose,

X: Number of guests

C (x) = total cost

CF (x) = fixed cost

CV (x) = variable cost

C (x) = CV (x) + CF (x)

For the situation presented,

CF (x) = 100

CV (x) = 15x

With this information, the function that provides the total cost is given by the expression:

C (x) = 15x + 100.

When there are 20 guests, the total cost of the banquet is:

C (20) = 15 (20) + 100 = 300 + 100 = 400

Conclusion: The total cost function is C (x) = 15x + 100 and the cost of a banquet for 20 guests is $ 400

Today is Jack’s birthday and Jill’s birthday. Jack is five and Jill is nine.

1. How many years ago was Jill twice as old as Jack?

2. When Jack is three quarters as old as Jill, how old will Jill be?

3. When Jill was three times as old as Jack, how old was Jack?

4. When Jill is four times as old as Jack is today, how old will Jack be?

Answers

Here we go! Sorry for the long explanations.

Final answer:

The problem involves simple arithmetic and algebra to work out the relationship between ages at different times. Jill was twice as old as Jack 1 year ago. The other parts of the problems are under-determined or have errors that prevent firm conclusions.

Explanation:

Let's solve each problem step by step:

How many years ago was Jill twice as old as Jack? Let's call the number of years ago y. Jill's age y years ago = 9 - y, and Jack's age y years ago = 5 - y. The equation based on the problem is 9 - y = 2(5 - y). Solving this equation, y = 1. So, Jill was twice as old as Jack 1 year ago.

When Jack is three quarters as old as Jill, how old will Jill be? Let's call Jill's future age f. Jack's future age will be 3/4 * f. We know Jack is currently 5 years old, so 5 + x = 3/4(f + x), where x is the number of years till that happens. To find the value of f and x, we need one more equation or piece of information, which is not provided.

When Jill was three times as old as Jack, how old was Jack? To find this out, we set up an equation similar to the first problem: let's call the number of years ago z. So (9 - z) = 3(5 - z), solving for z gives us z = 4.5, but since they can't be half years old, we must consider whole years; thus, this situation hasn't occurred given their current ages or an error exists in the problem.

When Jill is four times as old as Jack is today, how old will Jack be? Jack is currently 5. So, when Jill is four times that age, she will be 5 * 4 = 20 years old. We cannot determine how old Jack will be at that time without knowing the difference in time between now and then.

The answer to this question is rotation
Because the shape didn't reflect across an axis and stay the same, it is not a reflection.
It didn't move and stay the same either, so we know it isn't a translation.

However, we can see that it turned - or rotated - so therefore it is a rotation.

What is the ratio of the circumference for two circles with areas of 6pi m^2 and 150 pi m^2

C.1:10
D.1.25

Answers

ratio is sqrt(6pi) : sqrt(150pi)
= 4.3416:21.7080

= 1:5


B
Final answer:

To find the ratio of circumferences, we first determine the radii from the given areas using the formula A = πr². Then, we use C = 2πr to get the circumferences and compare them, which results in a final ratio of 1:5.

Explanation:

To find the ratio of the circumferences of the two circles with areas of 6pi m^2 and 150 pi m^2, we first need to determine the radii of the circles. The area of a circle (A) is given by the formula A = πr². Solving for the radius (r) gives us r = √(A/π).

For the first circle:
A = 6π m²
So the radius is r1 = √(6π/π)r1 = √6 m

For the second circle:
A = 150π m²
So the radius is r2 = √(150π/π)r2 = √150 m

Now we can find the circumferences using the formula C = 2πr.

For the first circle:
C1 = 2π√6 m

For the second circle:
C2 = 2π√150 m

Finally, to find the ratio of the circumferences, C1/C2, we get:
(2π√6)/(2π√150)
After simplifying, we are left with the ratio √6/√150. This simplifies to √(6/150) which is √(1/25) or 1/√25. And since √25 is 5, we have a final ratio of 1:5.

Combine and simplify the following radical expression. 2 over 3 times cubed root of 5

Answers

Final answer:

The radical expression ⅓∛5 simplifies to 2/3 × cubed root of 5, and cannot be simplified further since 5 is a prime number.

Explanation:

To combine and simplify the given radical expression, 2 over 3 times cubed root of 5, we first understand that the expression is in the form ⅓∛5, which can also be written as ⅓(5¹³). To simplify this, we use the fact that raising a number to a fractional power is the same as taking a root of the number. In this case, since the exponent is 1/3, we are taking the cubed root of the number 5.

Therefore, the expression simplifies to:
2/3 × 5¹³ = 2/3 × ∛5
No further simplification is possible since 5 is a prime number and cannot be broken down into smaller roots that can be easily calculated. The final simplified form of the expression remains 2/3 × ∛5.

Final answer:

To combine and simplify the expression 2/3 * 5^(1/3), rewrite 5^(1/3) as the cube root of 5 and multiply it by 2/3. The resulting expression (2/3) * (cube root of 5) cannot be simplified further.

Explanation:

To combine and simplify the expression 2/3 * 5^(1/3):

We can rewrite 5^(1/3) as the cube root of 5.

Multiplying 2/3 by the cube root of 5 gives us (2/3) * (cube root of 5).

Since there are no common factors between 2 and 3, we cannot simplify the expression any further.

Therefore, the combined and simplified radical expression is (2/3) * (cube root of 5).
