Answer:
See below.
Step-by-step explanation:
2a. E = 8.25h + 1.2n
2b. E = 8.25 * 3.5 + 1.2 * 10 = $40.88
2c. 8.25 * 8 + 1.2n = 91.2
66 + 1.2n = 91.2
1.2n = 25.2
n = 21 magazines.
Answer:
Step-by-step explanation:
<u>The circle has a circumference:</u>
This the is arc of full length θ = 360°
<u>Each degree of arc length is:</u>
- s = 2πr*θ / 360 = πrθ / 180
<u>We have:</u>
<u>The arc length is:</u>
- s = π*6*25/180 = (5/6)π inches terms of π
<u>The same arc is:</u>
- s = (5/6)*3.14 = 2.62 inches (rounded)
4/11 because when you multiply 5x4x you get 20x , so 8-2x=20x. Then you move the terms with variables and get -2x-20x=-8. This gives you the answer that -22x=8 and when u divide by 22 to both sides, you get 4/11.
