Answer:
C. The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days
Step-by-step explanation:
So 5 time 4 equals 20...!
80 minus 20= 60
Answer:
16. 29 and 30
17. C. 30 D. 31
Step-by-step explanation:
16. Given the inequality c ≤ $30, which is used to represent the situation, it implies that possible value of c must be equal to $30 or less than $30.
Two possible solutions form the options given would be:
29 and 30.
29 is less than 30, and 30 is equal to 30.
17. The inequality given is b ≥ 30.
This implies that possible solutions will be equal to 30 or greater than 30. It cannot be less than 30.
The solutions that apply would be:
30 (this is equal to 30) and 31 (this is greater than 30).
The remaining options don't satisfy or make the inequality statement true.
The speed in feet per second may be calculated by the proper dimensional analysis and the given conversion factors. That is,
(40 mile / hr) x (5280 feet / 1 mile) x (1 hr / 3600 s) = 58.67 ft / s
Thus, the Jackrabbits' speed may also be expressed as 58.67 ft / s.
Hey there,
Your answer would be in the attachment above.
Hope this helps.

Answer:
Step-by-step explanation:
30t - 5t² = 10
5t² - 30t + 10 = 0
t = [30 ± √(30² - 4 ⋅ 5 ⋅ 10)] / [2 ⋅ 5]
= [30 ± √700] / 10
= [30 ± 10√7] / 10
= 3 ± √7
≈ 0.35 seconds and 5.65 seconds
