Answer:
$10.88 or round up to $11
Step-by-step explanation:
Since 15 is expressed as a percent, you can convert it to a decimal.
.15, which can also be 15/100 if you were to write it as a fraction.
You are trying to find 15% of 72.50 so you would need to multiply your new decimal (.15) to your meal total. This will give you 10.875 or 10.88.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
4x² - 5 = 75
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 5 on both sides: 4x² = 80
- [Division Property of Equality] Divide 4 on both sides: x² = 20
- [Equality Property] Square root both sides: x = ±2√5
10/12= $.83 per inch
20/18= $1.11 per inch
160 cm because if I am correct, then two of the sides are labeled as 10 cm. Which means that they are both the same measurement.
3+6-7=2
2x5/2=5(1)
6x5/2=15(2)
The area shaded: (1)+(2) => 5+15=20
Answer: 20
