Answer:

Her average speed is 48 miles per hour.

Step-by-step explanation:

1. You have to do order of operations in reverse (PEMDAS in reverse)

2. Divide 36 by 3/4 which would be to multiply by the reciprocal (multiplying 36 by 4/3)

3. The answer would then be r=48

Hey there!

<em>C = 0.25x + 40</em>

(a) For this part we solve for C when x = 240. Substitute 240 in for x.

C = 0.25(240) + 40

Multiply 240 by 0.25.

C = 60 + 40

Add.

C = 100

The cost is $100.

<u>Check</u>

100 = 0.25(240) + 40

100 = 60 + 40

100 = 100

(b) For this part we solve for x when C = 180. Substitute 180 for C.

180 = 0.25x + 40

Subtract 40 from each side.

140 = 0.25x

Divide each side by 0.25.

560 = x

This person drove 560 miles.

<u>Check</u>

180 = 0.25(560) + 40

180 = 140 + 40

180 = 180

(c) For this we must make an inequality with C = 150.

Since they want the cost to be <em>no more than</em> 150, we will use the ≥ symbol.

C ≥ 0.25x + 40

Substitute 150 for C. Solve for x.

150 ≥ 0.25x + 40

Subtract 40 from each side.

110 ≥ 0.25x

Divide each side by 0.25.

440 ≥ x

The max number of miles they can drive is 440.

<u>Check</u>

150 ≥ 0.25(440) + 40

150 ≥ 110 + 40

150 ≥ 150

Hope this helps!

The area of the given trapezoid will be the sum of the areas of the triangular part and the rectangular part.

Now, the area of the rectangle, A_1 is:

A_1=length \times width=2\times 1.5=3 squared yards

Likewise, the area, A_2 of the triangle will be:

A_2=\frac{1}{2}\times base\times height=\frac{1}{2}\times 5\times 1.5=3.75 yd^2

Thus, the area of the trapezoid=A_1+A_2=3+3.75=6.75 yd^2

Thus the first option is the correct option.
