Answer:
Area = 77 yd²
Step-by-step explanation:
Width = w
Length = w+4
Perimeter =36
Perimeter = L + L + w + w
36 = w+4+w+4+w+w
4w+8 =36
Subtract 8 from both sides
4w = 36 - 8
4w =28
Divide both sides by 4
W= 28/4
W= 7yd
Therefore length = w+4 = 7+4 = 11 yd
Area = length x width
Area = 11× 7
Area = 77 yd²

Answer:
P = 0.23375
Step-by-step explanation:
given,
you remain in store for 15 minutes.
you friend remains in store for 10 minutes.
probability that they are store at the same time
from the graph attached below
shaded region shows the required probability,.
probability of the square = 1
probability of the shaded region = 1 - (area of lower triangle - area of upper triangle)
area of lower triangle = \dfrac{1}{2}(0.85)(0.85)
= 0.36125
area of the upper triangle = \dfrac{1}{2}(0.9)(0.9)
= 0.405
probability of the shaded region = 1 - (0.36125+0.405)
= 0.23375
Answer: y = -1x + 8
Step-by-step explanation: linear equations must be written in the format
y = mx + b from.
m represents the slope which it -1
b represents the y-intercept which is 8.
Just substitute the slope and y-intercept in the m and b places and that is a linear equation.
