Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
1 carton : 8 boxes for 2.80 = 2.80/8 = 0.35 per box (All natural juice)
1 carton : 6 boxes for 1.98 = 1.98/6 = 0.33 per box (Just juice)
difference between the 2 is 0.02 (2 cents)
if she paid 7.92 for x cartons of Just Juice, 7.92 / 0.33 = 24 boxes...and there are 6 boxes per carton.....24/6 = 4 cartons were bought for $ 7.92
price for same number of juice boxes of All Natural juice is :
24 * 0.35 = $ 8.40
Answer:
D.
Step-by-step explanation:
(x-3)(x+1)(x+5)
Answer:
2) (0,-3)
Step-by-step explanation:
hello :
put x=0 and y= -3 in this system !
Y = 3/4x - 3
3x - 4y = 12
- 3 = 3/4(0) - 3 means : -3 = -3 ......true
3(0) - 4(-3) = 12 means : 12= 12 ......true
