Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2(L+W)
L is the length of the triangle
W is the width
If the perimeter of a rectangle is represented by the expression 
In order to know what wat each part represents, we will rewrite the given equation in the form 2(L+W).
Given

Perimeter of a rectangle

Compare the given function with the perimeter to get L and W

Hence the following statements explain correctly what each part of the expression represents
- One side of the rectangle measures x (the length)
- One side of the rectangle measures 3x + 1 (the width)
- 2 is the coefficient in each term that represents 2 lengths and 2 widths in a rectangle.
Ideally, the smaller the sample population, the more accurate is the sampling result, but it will take longer time if the number of samples is huge.
The answer to the above question is ideally 20 light bulbs per sampling.
Let x be the no. of seconds it takes for the balloons to be at the same height.
7+3x = 12+2x
Deduct both sides by 2x.
7+x = 12
Deduct both sides by 7.
x = 5
Ans: It will take 5 seconds for the balloons to be at the same height.
Answer:
12.75
Step-by-step explanation:
c = π x d
40.035= 3.14 x d
40.035/3.14 = 12.75
Answer:
Step-by-step explanation:
So you do 3.29*12.6=41.454. Since we are dealing with money we round to get $41.45
