Answer:
40
Step-by-step explanation:
Im assuming its just a regular number cube with 6 numbers
there are only 2 odd numbers above 1 ( 3 and 5)
so the ratio is 2/6
you want to know how manny times (x) will you roll those numbers out of 78 roll
the ratio is x/78
multiply
(2/6) = (x/78)
cross multply to give you 6x= 156 and divide by 6
<span>to give you x = 26

Answer:
b
Step-by-step explanation:
given s(t) = t³ - 5t then
v(t) = s'(t) = 3t² - 5 and
v(3) = 3(3)² - 5 = 22 m / s, and
a(t) = v'(t) = 6t, then
a(3) = 6 × 3 = 18 m / s²
The rate would be 75 miles in 1 hour.
Set up a proportion to solve this:
3 1/8 miles in 2.5 minutes gives us the ratio 3.125/2.5.
The second ratio would be x miles in 60 minutes, or x/60.
3.125/2.5 = x/60
Cross multiply:
187.5 = 2.5x
Divide both sides by 2.5:
187.5/2.5 = 2.5x/2.5
75=x
