Answer:
The width of the flag is 70 ft.
Step-by-step explanation:
The shape of a flag is mostly rectangular.
The perimeter of a rectangle is,
Given:
Perimeter of flag = 460 ft.
Width = <em>w</em>
Length (<em>l</em>) = 90 + <em>w</em>
Determine the value of width as follows:
Thus, the width of the flag is 70 ft.
To find the value of p, isolate/get the variable "p" by itself in the equation:
19 = 4p - 5 Add 5 on both sides
19 + 5 = 4p - 5 + 5
24 = 4p Divide 4 on both sides to get "p" by itself
6 = p Your answer is B
PROOF
19 = 4p - 5 Substitute/plug in 6 into "p" since p = 6
19 = 4(6) - 5
19 = 24 - 5
19 = 19
Answer:
B
Step-by-step explanation:
We simply find the area and then multiply that by $1.5 to get our answer.
We need to break down the composite figure and add up each individual area to get total area.
To the right, we will have a trapezoid with bases:
base 1 (top) = 31 - 9 = 22
base 2 (bottom) = 12 (given)
and
height = 9 + 3 = 12
Putting into trapezoid area formula we have:
Also, the left side, we have a skinny rectangle with height 3 and length 9. Thus, the area is:
3 * 9 = 27
Total area is 204 + 27 = 231
Each square feet is $1.50, hence total cost = 231 * 1.5 = $346.50
B is the right answer.
