The answer is 63 because you have set up the proportion 1.5 over 3 = 31.5 over x and then you cross multiply 31.5 times 3 and you get 94.5 then you divide that by 1.5 and you get 63.
The arcs in the corners of the triangle mean that all 3 angles are the same.
Because the 3 angles are all the same this means that all 3 sides are also the same.
To solve for X, we can set 2 of the equations to equal each other and solve for x:
6x-3 = 3x +6
Add 3 to each side:
6x = 3x +9
Subtract 3x from each side:
3x = 9
Divide both sides by 3:
x = 9/3
X = 3
And if you replace x with 3 in each of the equations, they all equal 15.
Answer:
I believe it would be 24 sq ft. Radius is a line draw from the center of the circle out, also known as 1/2 of the circle. So by dividing 48 by 2 you should get 24.
A cube has equal length, height and depth.
The area of one face is 5inches * 5inches, which would equal 25inches^2.
Multiply this by 6, for the 6 faces on a cube, and we get 150inches^2 of cardboard.
