The answer is 15
To find the answer set up an equation like this
a2 + b2 = c2 (2 means squared)
Here we are trying to find the value of a so we know the values of b and c.
a2 + 20(squared) = 25(squared)
20 squared equals 400
25 squared equals 625
a2 + 400 = 625
Subtract 400 from 625 which equals 225.
Now we find the square root or closest square root of 225.
The square root of 225 is 15. 15 x 15 = 225
Well,
we know that we need to accumulate points from x and y to reach 20 points.
since x provide 3 and y provide 4 points, the formula would be :
3x + 4y = 20
or it can be written as :
y = (3x/4)+5
hope this helps
Answer:
6.96
Step-by-step explanation:
Answer:
Width= 30
Length= 62.5
Step-by-step explanation:
<u>First we simplify the length to width ratio </u>
25/12=
2 1/12 ratio of length to width
width=x
length=2 1/12x
<u>Make the equation for this ratio's perimeter being equal to 185</u>
2(2 1/12x) + 2(x)=185
<u>Solve for x</u>
4 1/6x +2x=185
6 1/6x=185
x=30
<u>Substitute the answer in for x to find the length and width</u>
Width= 30
Length= 2 1/12(30)
Length= 62.5
