(5/8):(1/4)= 5/8 • 4= 20/8=5/2 = 2 and 1/2
The perimeter of a rectangle, is all of the sides added up.
In a rectangle, there are two widths (right and left), and two lengths (up and down)
So:
Perimeter = 2 × width + 2 × length.
To get the equation we just substitute in the values that we are given:
length = (x)
width = (x - 4)
perimeter = 87
So just put these values into: perimeter = 2 × width + 2 × length:
87 = 2(x) + 2(x - 4)
_____________________________
Answer:
The equation is: 87 = 2(x) + 2(x - 4)
<em>(note: this can be simplified down like so:</em>
<em>87 = 2x + 2x - 8</em>
<em>87 = 4x - 8</em>
<em>95 = 4x</em>
23.75 = x

If at the end of the study, the sociologist had a sample of 500 expectant parents and he estimates that there are 6 million expectant parents in the United States then the value of n is 500.
Given that the sample size is 500 and the number of expectant parents be 6 million.
We are required to find what n represents and value of n.
The value of n is 500. Small n shows the sample size and capital N shows the size of population.
Sample is that part of the population that represents the characteristics of the whole population.
Population is the number of individuals present in the area which a researcher wants to observe.
Hence if at the end of the study, the sociologist had a sample of 500 expectant parents and he estimates that there are 6 million expectant parents in the United States then the value of n is 500.

Answer:
35 days
Step-by-step explanation:
We know that L(t) is the tangent to the line A(t) at t = 30
At t = 30:
A (30) ≈ 0.783 →(30, 0.783) = (t, A(t))
A¹ (30) ≈ -0.56
let -0.56 = M
For a linear function, a straight line equation applies which leads to
(y-y₁) = m (x-x₁) ...1
So for this problem we have;
A (t)-0.783 = -0.56 (t - 30)
when there is 0.5 pounds of grass, A (t) - 0.5, then using the equation (1)
(0.5 - 0.783) = -0.56 (t-30)
t = 35.054
≈ 35 days
