Answer:
18
Step-by-step explanation:
15 + Percentage increase =
15 + (20% × 15) =
15 + 20% × 15 =
(1 + 20%) × 15 =
(100% + 20%) × 15 =
120% × 15 =
120 ÷ 100 × 15 =
120 × 15 ÷ 100 =
1,800 ÷ 100 =
18
Answer:65
Step-by-step explanation:
Answer:
Step-50*t + 30*m = 1500, (1) (pounds)
4*t + 3*m = 138. (2) (cubic feet)
From (2), express 3m = 138 - 4t, and substitute it into (1). You will get
50t + 10*(138-4t) = 1500, or
10t = 1500 - 1380 ---> 10t = 1120 ---> t = 112 TVs.
From this point, find the number of microwaves on your own.
step by-step explanation:
Answer:
1/2 pi
Step by step explanation:
Find the circumference
2πr = 2xπx2 = 4π
Find the angle of JHI
Since 1/2π is 1/8 of 4π,
Angle JHI should also be 1/8 of 360 = 45 degrees
To find area, 45/360 x π X 2^2
= 1/8 x 4π
= 1/2 π
