Answer: $16.15
Explanation:
Discount = 10% x $8.50 = 0.1 x $8.50 = $0.85
Price after discount = $8.50 - $0.85 = $7.65
Total Amount = $8.50 + $7.65 = $16.15
Answer:
49π
Step-by-step explanation:
The area for the formula of a circle is πr^2, where r is for radius. A radius is half of the diameter, which in this case is 14. 14/2 = 7, so the radius is 7. π(7)^2 = 49π.
Answer:
one side of the room would be 11 feet
Step-by-step explanation:
the area is 121 square feet
take the square of it and it would be 11 feet in length and 11 feet in width
Based on the definition of supplementary angles, the measure of both angles are: 80° and 100°.
<h3>What are Supplementary Angles?</h3>
The sum of angles that are supplementary to each other equals 180 degrees.
Let the measure of the supplementary angle be x.
The other angle will be: x + 20.
(x + 20) + x = 180
x + 20 + x = 180
2x + 20 = 180
2x = 180 - 20
2x = 160
x = 160/2
x = 80°
The other angle will be x + 20 = 80 + 20 = 100°.
The measure of the angles are: 80° and 100°.
