11 cups of strawberries ... 6 pitchers of juice
x cups of strawberries = ? ... 1 pitcher of juice
If you would like to know what is the number of cups of strawberries in each pitcher, you can calculate this using the following steps:
11 * 1 = 6 * x
11 = 6 * x /6
x = 11/6
x = 1 5/6 cups of strawberries
Result: You will need 1 5/6 cups of strawberries in each pitcher.
Answer:
Mass=1068gr
Step-by-step explanation:
Volume= 7.5 cm x 2.53 cm x 7.15 cm=135.7cm^3
Density=7.87gr/cm^3
Mass=Density*Volume=135.7*7.87=1068gr
Answer:
in steps
Step-by-step explanation:
upper square: P = 20x² + 8
<u>side: P/4 = 5x² + 2</u>
<u>A = side² = (5x² + 2)² = 25x⁴ + 20x² + 4</u>
Middle equilateral Triangle: A = x² + 4x + 4 base = 2x + 4
A = base x height / 2
(x + 2)² = 2 (x + 2) x height /2
<u>height = x + 2</u>
<u>perimeter = 2 (x + 2) x 3 = 6x + 12</u>
Lower trapezoid: A₁ = 2x² + 24x + 40 = 2 (x² + 12x + 20) = 2 (x + 2) (x + 10)
A₁ = (x + 10)² = 2 (x + 2) (x + 10)
x + 10 = 2x + 4
x = 6
<u>A₂ = (2x + 4) (x + 10) / 2 = (16 x 16) / 2 = 128</u>
A₁ = (6 + 10)² = 256
<u>AT = 256 + 128 = 384</u>
