Answer:

Richard's gross pay for the month was $ 4,512.5.

Step-by-step explanation:

Given that Richard Klein works as auto mechanic and earns the following commission rates: 3.00 percent for oil changes, 5.00 percent for tune ups and 6.25 percent on auto parts sales; and he is guaranteed a minimum salary of $ 2,450.00 per month, if last month he brought in $ 2,500.00 in oil changes, $ 4,500.00 in tune ups and sold $ 28,200.00 in parts, to determine what is his gross pay for the month the following calculation must be performed:

2,450 + (2,500 x 0.03) + (4,500 x 0.05) + (28,200 x 0.0625) = X

2,450 + 75 + 225 + 1,762.5 = X

2,450 + 2,062.5 = X

4,512.5 = X

Thus, Richard's gross pay for the month was $ 4,512.5.

Answer:

1.2

Step-by-step explanation:

Since we are rounding it by the tenth, it means we are rounding to the 1st digit to the right of the decimal.

We know 7 is greater then 5 meaning we round up

.1 + .1 is equal to .2 meaning its 1.2

If you still don't understand, I recommend you talk to your teacher

Answer: The answer is 1.2

Step-by-step explanation: Since this is to the nearest tenth  we are looking at the  first two numbers after the decimal point the second number 7 is greater then 5 the first number will be  greater if it was less then 5 or 5 we would round down now  we discard the rest including the second number which leaves us with the rounded first number of 2 now it's 1.2

Answer:

x = - 3.75

y = 28.75

Step-by-step explanation:

[tex] \begin{cases} x + y = 25\\\\ 5x + y = 10 \end{cases} [/tex]

Since, x + y = 25

Therefore, y = 25 - x..... (1)

5x + y = 10......(2)

Plug y = 25 - x in equation (2), we find:

5x + 25 - x = 10

5x - x = 10 - 25

4x = - 15

x = - 15/4

x = - 3.75

Plug x = - 3.75 in equation (1), we find:

y = 25 - (- 3.75)

y = 25 + 3.75

y = 28.75

(x, y) = (-3.75, 28.75)

Step-by-step explanation:

since city t, s, and P make a right angle we can use the Pythagorean theorem to find the hypotenuse (distance from t to p) 1180 squared=1,392,400 and 660 squared =435,600 so now we add them together and take its square root which is 1352.0

Answer:

12

Step-by-step explanation:

it will be 12 inches greater

The volume of the front door is 72 cubic inches greater than the volume of the bedroom door.

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

Assuming that the bedroom door has the same height as the front door, we can use the formula for the volume of a rectangular solid to calculate the volume of each door.

Let L, W, and H be the length, width, and height of the front door, and let L' and W' be the length and width of the bedroom door.

We know that Lx W = 72 (since the area of the base is 72 square inches), and L' x W' = 60 (since the area of the base is 60 square inches).

The volume of the front door is given by V = LWH.

The volume of the bedroom door is given by V' = L'*W'*H.

Since the height is the same for both doors, we can divide V by V' to get the ratio of the volumes:

V/V' = (LWH)/(L'*W'H)

V/V' = (LW)/(L'*W') (canceling out the heights)

Substituting in the given values, we get:

V/V' = (72)/(60)

V/V' = 6/5

This means that the volume of the front door is 6/5 times the volume of the bedroom door.

To find the difference in volume, we can subtract the volume of the bedroom door from the volume of the front door:

V - V' = (6/5)*V' - V'

V - V' = (1/5)V'

V - V' = (1/5)(L'*W'*H)

Substituting in the values for L', W', and H, we get:

V - V' = (1/5)*(L' x W' x H)

V - V' = (1/5)(√(60) x √(60) x H)

V - V' = (1/5) x 360

V - V' = 72

Therefore,

The volume of the front door is 72 cubic inches greater than the volume of the bedroom door.

Answer:

y = x+1

Step-by-step explanation:

Slope-intercept form

(y = mx+b)

m = slope and b = y-intercept

The line crosses the y-axis at (0, 1), therefore the y-intercept (b) = 1

The slope (m) = 1

Because the slope is 1, it does not need to be written in the equation, as any number multiplied by 1 is that number.
