Answer:
<u>125.6 in²</u>
Step-by-step explanation:
Area shaded :
- 2 × Sector (72°)
- 2 x πr² x θ/360
- 2 x 3.14 x 100 x 72/360
- 6.28 x 100 x 1/5
- 20 x 6.28
- <u>125.6 in²</u>
<span>Let pn = The total number of pizza crusts </span>made by the end of the nth week
For Pepe's Pizza:
Pn + 52 + 180n
For Diannes's
Pn = 25 + 90n
<span>The total number of pizza crusts made by Pep's Pizza equals twice the total number of pizza crusts made by Dianne's Delicatessen when:
52 + 180n = 2 (26 + 90n)
52 + 180n = 52 + 180n
</span>This equation is satisfied for any value of n, so Pepe's always makes twice as much as Dianne's
Since dimes + quarters = 22
And dimes are 0.10 cents as quarters = 0.25 cents
Let’s make d = dime, q = quarter
d + q = 22
0.10d + 0.25q = 4.00
Let’s use substitution
d + q = 22, get d or q by itself
d = 22 - q (plug into second equation)
0.10(22-q) + 0.25q = 4
2.2 - 0.10q + 0.25q = 4
2.2 + 0.15q = 4
0.15q = 1.8, q = 12
Since there are 12 quarters you know there are 10 dimes (22 in total)
Solution: 10 dimes, 12 quarters
