x 
=
7 x 1 = 7
8 x 2 = 16
Let me know if this helps!
So, to do this, you would multiply inside the radicals. The answer would be the fourth root of x^4, or x.
Answer:
Step-by-step explanation:
use the formula 
so you would get
Those negatives becomes a positive and you get 4+8 = 12 and 0+7 = 7
you final answer would be
Answer:
He'll need 288 cups to make a waffle on his 24 foot diameter circular griddle.
Step-by-step explanation:
In order to find out how much batter Danny needs we first need to compute the area of the first pans, since it is a circular pan their area is given by A = 2*pi*r. So we have:
Area of the first pan = 2*pi*(6/2) = 18.84 square inches
Area of the second pan = 2*pi*(24/2) = 75.36 square foots
We now need to convert these values to be in the same unit, we'll convert from square foots to square inches:
Area of the second pan = 75.36 * (12)^2 = 10851.84 square inches
We can now use a proportion knowing that the batter and the thickness of the waffles are the same. If 0.5 cup of flour can make a waffle on 18.84 square inches then x cup of flour can make a waffle on 10851.85 square inches. Writing this in a mathematical form, we have:
0.5/x = 18.84/10851.84
18.84x = 0.5*10851.85
x = 10851.85*0.5/18.84 =288 cups
Rectangles:
2 x 3 = 6 sq in.
2 x 4 = 8 sq in.
2 x 6 = 12 sq in.
Triangles: (since there are 2 you don't need to do 1/2 x base x height)
3 x 4 = 12 sq in.
Now add 6+8+12+12 = 38 sq in.
