1 answer:
Dahasolnce [82]3 years ago
3 0

Answer:

a. The constant = 45

b. The unit rate is 45 miles per hour

c. d = 45t

Step-by-step explanation:

a. ∵ d ∝ t

∴ d = kt

∵ d = 90 at t = 2

∴ 90 = k(2)

∴ k = 90 ÷ 2 = 45

∴ The constant of proportionality is 45

b. ∵ k = d(miles) ÷ t(hours) = 45

∴ The unit rate is 45 miles per hour

c. The equation is ⇒ d = 45t

PLS HELP Find the area of the shaded region. PLEASE
anastassius [24]
<h3>Answer:   64 cm^2</h3>

Reason:

The parallelogram has area of A = base*height = 10*7 = 70 cm^2

The white rectangle has area of B = base*height = 3*2 = 6 cm^2

The shaded region has area of A - B = 70 - 6 = 64 cm^2

If you are curious why the rectangle and parallelogram use the same formula to get the area, notice how you can move that triangle on the left toward the right side so that a rectangle can be formed.
