Answer:
This is because the number '20' is not a perfect square.
Step-by-step explanation:
If you find 
, you will be getting 4.4721935955... which is not a whole number, thus 20 is not a perfect square.
Answer: If the 40% off coupon is used, the subtotal will be $12.69
The gratuity would be exactly $4.23 (He will probably leave $4.25)
Step-by-step explanation: To find out the amount of the discount
.40 × 21.15 = 8.46
To find the new subtotal, subtract 12.15 - 8.46 = 12.69
To figure the tip: .20 × 21.15 = 4.23
Changing the percent to a decimal means divide the 20 by 100.
Answer:
4
Step-by-step explanation:
3*10=10+5s
30 = 10 + 5s
30-10 = 5s
or, 20/5= s
or, 4 =s
therefore the value of s is 4.

Formula:
a^2+b^2=c^2
c^2: Is the hypotenuse.
For a^2 and b^2, you have to multiply both it by its self.
Then, add both.
Next, you square root it.
Example:
a^2+b^2=c^2
14^2+7^2=c^2
196+49=c^2
245=c^2
15.64=c^2
The solution to the given equation is x > 5.3
<h3>Solving linear inequality</h3>
Inequality are expression that are separated by an equal sign.
Given the inequality;
16(1/4 x - 1/2) > 24- 2x
Expand
4x - 8 > 24 -2x
Collect like terms
4x + 2x > 24 + 8
6x > 32
x > 32/6
x > 5.3
Hence the solution to the given equation is x > 5.3
