Answer:
Option 1 is correct that is square root of 18.
Step-by-step explanation:
We will use pythagoras theroem to find the length of hypotenuse

Here, c is hypotenuse,a is one leg and b is the other leg.
Here, a=b=3
On substituting the values in the formula we get:


Hence, Option 1 is correct that is square root of 18.
First, calculate 18% of 23.
23 x 0.18 = 4.14
Then, add this value (the increase) to the original value of 23.
23 + 4.14 = 27.14
Rounding off, we get 27.
Answer:
$13.25
Step-by-step explanation:
- Change 45% in a decimal which is 0.45.
- Multiply 0.45 and 25.
- That will give you $11.25.
- Change 8% into a decimal which is 0.08.
- Multiply 0.08 and 25.
- That will give you $2.
- Then add $11.25 and $2.
- Your final answer is $13.25
