Answer:
9
Step-by-step explanation:
1 feet is 12 inches, so 12 feet is 12 * 12 = 144 inches.
If studs are placed 18 inches apart, in 144 inches, there will be:
<u><em>But remember, there is a stud at the very beginning (at 0 feet).</em></u>
<u><em /></u>
So in total there are going to be 9 studs
Answer:
Option A.Exponential decay, 55% decrease
we have
This is a exponential function of the form
where a is the initial value
b is the base
b=(1+r)
r is the rate of change
In this problem
a=54
b=0.45
so
0.45=1+r
r=0.45-1
r=-0.55
Convert to percentage
r=-55% ------> is negative because is a exponential decay
Replace x with the binomial a - 2.
f(a - 2) = [3(a - 2) + 5]/(a- 2)
f(a - 2) = [3a - 6 + 5]/(a - 2)
f(a - 2) = [3a - 1]/(a - 2)
f(a - 2) = (3a - 1)/(a - 2)
Done.
times 
equals 1
Solution:
Given expression is at what times equals the whole.
Whole means 1 in a fraction.
Let us take the number of times be x.
Multiply by on both sides of the equation.
Hence the fraction times equals 1.
Answer:
64/27
Step-by-step explanation:
Take the reciprocal of 3/8: 8/3
Multiply this number by 8/9: 8/9 * 8/3 = 64/27
Therefore, 8/9 ÷ 3/8 = 64/27
