Answer:
Step-by-step explanation:
Givens
r = 14 miles / hour
Problem
Convert to feet per second.
Solution
Later on, you will learn how to solve these kinds of conversion problems using a method called Unit Analysis. Since you likely have not been taught this method, will just use proportions.
1 mile = 5280 feet
14 miles = x Cross multiply
x = 14 * 5280 Simplify
x = 73920 feet
1 hour = 3600 seconds
Answer
r = 73920 feet / 3600 seconds
r = 20.533 feet / secpmd
15kg=33 lbs
48.4 lbs/2.2 lbs. =22 kg
1 kg = 2.2 lbs so when you need to make a conversion wityh kilograms and pounds write that out then put how ever many pound you need to get to under the 2.2 lbs and cross multiply same with the kilograms.
Answer:
y = 1/4x - 3
Step-by-step explanation:
y + 2 = 1/4(x - 4)
y = 1/4x - 3
Answer:
3rd one
Step-by-step explanation:
Answer:
x² - 2x - 35
Step-by-step explanation:
x₁ = -5
x₂ = 7
-5 * 7 = -35
5 - 7 = -2
x² - 2x - 35 = 0
(x - 7)(x + 5) = 0
x - 7 = 0
x₁ = 7
x + 5 = 0
x₂ = -5
