You can download this app called Symbolab but the answer is -144xy^2
The answer is 12/100 or 12% probability.
The total group is 100 people, with only 12 being moderate that are high school only.
Answer:
Three ppl, Twelve dogs
Step-by-step explanation
x=hoomans
y=doggos
x+y=15
2x+4y=54
x=15-y
2(15-y)+4y=54
30-2y+4y=54
2y=24
y=12
so that means there are 12 doggos
and since x=15-y, which is 15-12, which is 3,
there are three hoomans
Your answer is:
C. 6.125
Hope this helped! -Perplxxd
How I found the answer: Divided 1 by 8, which gave me .125 and then added the six before the decimal, therefore I have 6.125
Answer:
Area = 16 in²
Step-by-step explanation:
Represent the length with L and the width with W
We have the following given parameters:
L = 4W
Perimeter = 20
Required
Determine the area.
The perimeter is calculated as thus:
Perimeter = 2(L + W)
Substitute 4W for L and 20 for Perimeter.
20 = 2(4W + W)
20 = 2 * 5W
20 = 10W
Solve for W
W = 20/10
W = 2
Recall that:
L = 4W
L = 4 * 2
L = 8
The area is then calculated as thus:
Area = L * W
Area = 8 * 2
Area = 16
Hence, the area is 16in²
