13 vehicles

To Find out the number of vehicles sold you just multiply the percentage by the Whole number
E.g:
65 people x 20%= 13
So 20% of 65 would be the number of vehicles sold
13
Hope this is simple and helpful.

Two mechanics worked on a car. The first mechanic worked for 15

nevsk [136]

Answer: For the sum of 130

First: $90

Second: $40

Step-by-step explanation:

We write equations for each part of this situation.

The Total Charge

Together they charged 1550. This means 1550 is made up of the first mechanics rate for 15 hours and the second's rate for 5 hours. Lets call the first's rate a, so he charges 15a. The second's let's call b. He charges 5b. We add them together 15a+5b=1550.

The Sum of the Rates

Since the first's rate is a and the second is b, we can write a+b=130 since their sum is 130.

We solve for a and b by substituting one equation into another. Solve for the variable. Then substitute the value into the equation to find the other variable.

For a+b=130, rearrange to b=130-a and substitute into 15a+5b=1550.

15a + 5 (130-a)=1550

15a+650-5a=1550

10a+650-650=1550-650

10a=900

a=$90 was charged by the first mechanic.

We substitute to find the second mechanic's rate.

90+b=130

90-90+b=130-90

b= $40 was charged by the second mechanic

Answer: $87^{\circ}$

Step-by-step explanation:

Because an angle inscribed in a semicircle is a right angle, $\angle B=90^{\circ}$

So, as angles in a triangle add to 180 degrees, $\angle A=180^{\circ}-90^{\circ}-3^{\circ}=\boxed{87^{\circ}}$

Which graph is a translation of f(x) = x2 , according the rule:

bixtya [17]

For this case we have the following original function:
$f (x) = x ^ 2
$
We apply the following transformation:
Vertical displacements:
Assume k> 0
To graph f (x) - k, move the graph k units down.
Applying the transformation for k = 5 we have:
$y = x ^ 2 - 5
$
Therefore, the graph moves 5 units down.
Answer:
Third graph
