Answer:
86.28 ft²
Step-by-step explanation:
The figure given consists of a rectangle and a semicircle.
The area of the figure = area of rectangle + area of semicircle
Area of rectangle =
Where,
l = 10 ft
w = 8 ft
Area of semicircle:
Area of semicircle = ½ of area of a circle = ½(πr²)
Where,
π = 3.14
r = ½ of 8 = 4 ft
Area of semi-circle = ½(3.14*4) = 6.28 ft²
Area of the figure = area of rectangle + area of semi-circle = 80 + 6.28 = 86.28 ft² (nearest hundredth)
Answer:
The correct answer is the associative property of addition.
Step-by-step explanation:
This property states that no matter which way we group things when adding, they will still create the same outcome. Since all of the symbols are addition, the answer is the same.
Answer:
Step-by-step explanation:
Given that :
Time spent = 5/6
Fraction of students graded = 3/5
Amount of time grading 3/5 of students = 5/6 hours
Total fraction of students = 1/1
If 3/5 of students take 5/6 hours
Then, 1/1 of students will take x
Using cross multiplication :
3/5 = 5/6
1 = x
3x / 5 = 5/ 6
3x * 6 = 5 *5
18x = 25
x = 25 / 18
x = 1.38888 hours
she paid $50.64
because 24 divided by 3 is 8 and that times 6.33 is $50.64
Answer:
P = $300
r = 0.15
n = 12
$544.61 (to the nearest cent)
$524.70 (to the nearest cent)
Step-by-step explanation:
P = principal amount = $300
r = annual interest rate in decimal form = 15% = 15/100 = 0.15
n = number of times interest is compounded per unit t = 12
<u>How much she'll owe in 4 years</u>
P = 300
r = 0.15
n = 12
t = 4
= $544.61 (to the nearest cent)
<u>Yearly compounding interest rate</u>
<u>How much she'll owe in 4 years at yearly compounding interest</u>
= $524.70 (to the nearest cent)
