Answer:
6. 1.01 x -10^5
7. 6 x -10^14
8. 550,000
9. 60,700,000
10. 0.000204
11. 0.0004
12. 7,000,000,000,000 > 3,500,000,000
7,000,000,000,000 (or 7 x 10^12) is greater by 2,000 times
15. 10^3 and 10^4
Second one ...... i hope it’s right
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
