Answer:
Well since we know that the perimeter of a square is four times the length of one of its sides. We just have to divide 5 by 4 to get the length of one side:
5feet /4 sides = 1.25 feet
And to finish off, we have to convert feet to inches:
1 foot = 12 inches
1.25 feet x inches
x inches = 12 inches x 1.25 feet ÷ 1 foot
x inches = 15 inches
Therefore, each side is 15 inches long.
Hope this helps!

Answer:
28.27530
Step-by-step explanation:
Given the expression 62.834 × 0.45, to solve this expression, first we need to convert it to fraction
62.834 = 62834/1000
0.45 = 45/100
Take the product if the resulting fraction:
62.834 × 0.45 = 62834/1000 × 45/100
= (62834×45)/1000×100
= 2,827,530/100,000
= 28.27530
Answer:
the correct answer is D
Step-by-step explanation:
Remember that the cone volume formula is
, with r = radius and h = height. Using our information, we can form our equation as such:
(I'll be keeping the answer in pi form.)
Firstly, solve the exponents:![V=\pi 4\frac{19}{3}](https://tex.z-dn.net/?f=%20V%3D%5Cpi%204%5Cfrac%7B19%7D%7B3%7D%20)
Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3
Answer:
D(4,-3)
Step-by-step explanation:
Given three of the vertices of the square: A(4, -7), B(8, -7),C(8, -3)
Let the coordinate of the fourth vertex be D(x,y).
We know that diagonals of a square are perpendicular bisector. So, the midpoint of both diagonals is the same.
The diagonals are BD and AC
Midpoint of BD = Midpoint of AC
![\left(\dfrac{8+x}{2},\dfrac{-7+y}{2}\right) =\left(\dfrac{4+8}{2},\dfrac{-7+(-3)}{2}\right)\\ \left(\dfrac{8+x}{2},\dfrac{y-7}{2}\right) =\left(\dfrac{12}{2},\dfrac{-10}{2}\right)\\ \left(\dfrac{8+x}{2},\dfrac{y-7}{2}\right) =\left(6,-5\right)\\$Therefore$:\\\dfrac{8+x}{2}=6\\8+x=12\\x=12-8\\x=4\\$Similarly$\\\dfrac{y-7}{2}=-5\\y-7=-5*2\\y-7=-10\\y=-10+7=-3](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7B8%2Bx%7D%7B2%7D%2C%5Cdfrac%7B-7%2By%7D%7B2%7D%5Cright%29%20%3D%5Cleft%28%5Cdfrac%7B4%2B8%7D%7B2%7D%2C%5Cdfrac%7B-7%2B%28-3%29%7D%7B2%7D%5Cright%29%5C%5C%20%5Cleft%28%5Cdfrac%7B8%2Bx%7D%7B2%7D%2C%5Cdfrac%7By-7%7D%7B2%7D%5Cright%29%20%3D%5Cleft%28%5Cdfrac%7B12%7D%7B2%7D%2C%5Cdfrac%7B-10%7D%7B2%7D%5Cright%29%5C%5C%20%5Cleft%28%5Cdfrac%7B8%2Bx%7D%7B2%7D%2C%5Cdfrac%7By-7%7D%7B2%7D%5Cright%29%20%3D%5Cleft%286%2C-5%5Cright%29%5C%5C%24Therefore%24%3A%5C%5C%5Cdfrac%7B8%2Bx%7D%7B2%7D%3D6%5C%5C8%2Bx%3D12%5C%5Cx%3D12-8%5C%5Cx%3D4%5C%5C%24Similarly%24%5C%5C%5Cdfrac%7By-7%7D%7B2%7D%3D-5%5C%5Cy-7%3D-5%2A2%5C%5Cy-7%3D-10%5C%5Cy%3D-10%2B7%3D-3)
