Answer:
<u>The correct answer is 58 1/2 feet. See below to understand the difference of both methods.</u>
Step-by-step explanation:
1. Let's review the information provided to us for solving the question using both methods:
Area of each student = 4 1/2 square feet
Number of students = 13
2. Let's use the first method to solve the question:
4 1/2 = 9/2 (Improper fraction because the numerator, 9 is bigger than the denominator, 2)
9/2 * 13 = 117/2
<u>117/2 = 58 1/2 square feet</u>
3. Let's use the second method to solve the question:
4 1/2 = 4 + 1/2 (Using addition to rewrite the fraction)
(4 + 1/2) * 13 = (4 * 13) + (1/2 * 13) (Distributive property of the multiplication)
(4 * 13) + (1/2 * 13) = 52 + 13/2 = 52 + 6 1/2
<u>52 + 6 1/2 = 58 1/2 square feet</u>
The amount of cashew mixed is 5 pounds
<h3>Word problem on total cost</h3>
Cost of 1 pound of cashew = $14
Cost of 1 pound of peanut = $6.50
Total cost of 1 pound of the mixed nuts = $10.25
Cost of 5 pounds of peanuts = 5 x $6.50
Cost of 5 pounds of peanuts = $32.50
Let the amount of cashew be x
Total cost of x cashew = 14x
Total amount of the mixed nuts = x + 5
Total cost of the mixed nuts = 10.25(x+5)
Total cost of the mixed nuts = 10.25x + 51.25
14x + 32.50 = 10.25x + 51.25
14x - 10.25x = 51.25 - 32.50
3.75x = 18.75
x = 18.75/3.75
x = 5
Therefore, the amount of cashew mixed is 5 pounds

Step-by-step explanation:
Answer:
25*pi or
78.5 square units.
Step-by-step explanation:
If there was no shaded area, the area of the circle would be pi * r^2
r = 10
Area = pi * 10^2
Area = 100 * pi
Since there is a shaded area, the shaded part looks to be 1/4 of the whole. There's no indication of what it actually is, but 1/4 should be close enough.
Area_shade = 1/4 (100*pi)
Area_shade = 25 * pi
That's one answer.
Another is 25 * 3.14 = 78.5 square units
