Answer:
a) 5^4 / 5^2, 5^2
b) 7^3 / 7^3, 7^0=1
c) 8^7/8^4, 8^3
Step-by-step explanation:
A quotient of two powers is basically the powers before its simplified. So for a 5 x 5 x 5 x 5 is 5 being multiplied by itself 4 times divided by 5 x 5 which is 5 being multiplied by itself 2 times. So this leads us to the conclusion that 5^4/5^2 for the quotient of two powers. Then using the rules of powers when dividing powers you subtract so in this case 4-2 is 2. So the answer is 5^2 for single power. The other problems are basically the same as well, just different numbers.
b) (7 x 7 x 7)/ (7 x 7 x 7)= 7^3/7^3=7^0=1
c)(8 x 8 x 8 x 8 x 8 x 8 x 8)/(8 x 8 x 8 x 8)= 8^7/8^4= 8^3
Answer:
8 slices
Step-by-step explanation:
To answer this question, we first need to know the area covered by the pizza.
Since it is circular in shape, we use the formula for the area of a circle.
Mathematically area of a circle = pi * r^2
Here, we were given the diameter but we know that D = 2r or r = D/2. This shows that the radius would be 14/2 = 7 inches
Now the area of the pizza is 22/7 * 7 * 7 = 22 * 7 = 154 square inch
Now we proceed to calculate the amount in calories present in the pizza;
That would be 154 * 14.04 = 2162.16 calories
one slice has 270 calories; The number of slices in 2162.16 calories would be 2162.16/270 = 8.008 which is approximately 8 slices
Call the length a, the width b
Perimeter = (a+b) x 2
We have : a - b = 4 and (a+b) x 2 = 56
-> a + b = 28
-> a - b = 4
=> a+b + (a-b) = 32
2a = 32
a = 16
b = 56:2-16 = 12
So, the length = 16 and the width = 12
