change 20 in to ft
20/12 = 1 2/3 ft
4 ft x ft
------- = ---------------
5 /3 ft shadow 120 ft
using cross products
4 * 120 = 5/3 x
480 = 5/3 x
multiply each side by 3/5
480 * 3/5 = x
288 ft
Answer:
120
Step-by-step explanation:
Is means equals and of means multiply
W = 30% * 400
Change to decimal
W = .30*400
W = 120
Step-by-step explanation:
oatmeal 12/8 = 1.5 per student
apple 27/6 = 4.5 per student
carmine gets 1.5 + 4.5 = 6 muffins
The midpoint lines are half the opposite side length.
Line DE is given as 7 , So Line F = 7 x 2 = 14
Line EF is given as 12, so Line D = 12 x 2 = 24
Line DF is given as 16, so line E = 16 x 2 = 32
The perimeter is the sum of the 3 sides:
Perimeter = 14 + 24 + 32 = 70
Surface area is 34 units2 or sq.
the volume is 10 units3 or cubed.
volume is the amount of cubes on the inside, and the surface area is each surface added together
