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

Answer:
0.006
Step-by-step explanation:
If 8= 538 Ib. then take the (538) and divide that by 8. <---- 8 for the 8 uniforms.
Your math should look like this: 538/8= about 67 pounds.
Then do 67*8= 536. (You started at 532 Ib.) this is just 2 pounds off*
So, your answer should be *67* pounds.
