Answer:
step 3, 4 and 5 are incorrect
Step-by-step explanation:
area of a circle = 3.14(radius)squared
3.14 x 25squared
=3.14 x 625
=1962.5
tip area of circle equals "Pies are squared" 

Step-by-step explanation:
11 ÷ 20 = 0.55
0.55 × 100 = 55
so 55%
Step-by-step explanation:
1. 6 factors of 2 means, 2 multiplied by itself 6 times. It can be written in the form of exponents as 2⁶.
2. 
The law of exponent is : 
So,

The correct option is (A).
3. If the power of any number is 0, then the value of that number is equal to 1.
So,

Hence, this is the required solution.
First, you need to get rid of the fraction by multiplying both sides by 20 and you would get:
4(x + 2) = 5(x + 6)
Now, you need to get rid of the parenthesis by distributing:
4x + 8 = 5x + 30
Subtract both sides by 5x:
-x + 8 = 30
Subtract both sides by 8:
-x = 22
Now, divide both sides by -1:
x = -22
P.S.: You don't really need a calculator to solve.
