6 0

Answer: 6 hours or 360 minutes

Step-by-step explanation:

First find out how long it takes to deliver to one house.

Convert hours to minutes.

2.5 x 60 = 150 minutes total

Divide to find the time per house

150 minutes / 130 houses = 1.15 minutes per house

Now multiply this rate by the number of houses (312).

312 x 1.15 = 360 minutes

If you want it in hours then divide by 60.

360/60 = 6 hours.

Answer:

<u>Given</u>:

R(x) = 59x - 0.3x²
C(x) = 3x + 14

<u>Find the following</u>:

P(x) = R(x) - C(x) = 59x - 0.3x² - 3x - 14 = -0.3x² + 56x - 14
R(80) = 59(80) - 0.3(80²) = 2800
C(80) = 3(80) + 14 = 254
P(80) = 2800 - 254 = 2546

Find the length of EF

Lisa [10]

Answer:

Step-by-step explanation:

1. First, we need to set up an equation to find the value of x and then the length of EF.

2. We know that DG is equal to 33, so we can add all the three sections it's cut into altogether to get 33. Therefore, we get an equation of: $3x - 28 + 3x - 30 + x = 33$

3. (Solving for x)

Step 1: Simplify both sides of the equation.

$3x - 28 + 3x - 30 + x = 33$
$(3x+3x+x) + (-28-30)=33$
$7x - 58 = 33$

Step 2: Add 58 to both sides.

$7x - 58 + 58 = 33 + 58$
$7x = 91$

Step 3: Divide both sides by 7.

$\frac{7x}{7} = \frac{91}{7}$
$x = 13$

4. Now that we know x is equal to 13, we can plug that value in for the expression 3x - 30.

$3(13)-30$
$39 - 30$
$9$

Therefore, the length of EF is 9.
