Answer:
1 and 1/4 cups
Step-by-step explanation:
1 and 2/3 ÷ 1 and 1/3 = 1 and 1/4
Answer:
A) x = .9y
B) x + .9y = .038
Substituting A) into B)
.9y + .9y = .038
1.8y = .038
y = .038 / 1.8
y = 0.0211111111
From equation A)
x = .038 -.9*.02111111111111111111111
x = .038 -.019
x = .019
CHECK
x * .9 = .019
.019 + .9 * .021111111111111 = .019 + .019 = .038

Volume of a Cylinder Formula: V = πr²h
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Volume <em>V</em> = 2000π ft³
Height <em>h</em> = 20 ft
Radius <em>r</em> = unknown
<u>Step 2: Solve for </u><em><u>r</u></em>
- Substitute in variables [Volume of a Right Cylinder Formula]: 2000π ft³ = πr²(20 ft)
- [Division Property of Equality] Isolate <em>r</em> term: 100 ft² = r²
- Rewrite: r² = 100 ft²
- [Equality Property] Square root both sides: r = 10 ft
