Answer: 12%
Step-by-step explanation:
Given
There are 70 dogs and 55 cats at the shelter
If 15 animals are adopted
Total no of animals =70+55=125
Percent of animals adopted is given by
In a mechanical system, it is a law that energy should be conserved. In this case, what is the initial energy should be equal to the total energy after the motion happened. We do as follows:
PE(at rest) = KE(during motion) + PE(after motion)
51450 J = KE(during motion) + 32781 J
KE(during motion) = 18669 J
The equation of the best fit line is
y = 0.1073x + 4.5365
where
x is the number of leg press reps
y is the time it takes to do a 40 yard dash
For 22 leg press reps"
y = 0.1073(22) + 4.5365
y = 6.8963 s
Answer:
Option A. 10 years
Step-by-step explanation:
we know that
Half-life 
is the amount of time required for a quantity to fall to half its value as measured at the beginning of the time period.
In this problem of a radioactive isotope is 10 years, which means that after 10 years half of the sample would have decayed and half would be left as it is.
After 10 years ( first half life) 5/2 = 2.5 g decays and 2.5 g remains left
Y = mx + b...subtract b from both sides
y - b = mx...now divide both sides by x
(y - b) / x = m
