V = 4/3 (pi r times ^3) = formula for this knowing that you than
Combine volumes up (1ft times 3.14) + (2ft times 3.14) + (3ft times 3.14)

To get the Greates Common Factor (GCF) of 84 and 210 we need to factor each value first and then we choose all the copies of factors and multiply them:
<span><span>84: 223 7</span><span>210: 2 357</span><span>GCF: 2 3 7</span></span>
<span>The Greates Common Factor (GCF) is: 2 x 3 x 7 = 42</span>
Make 2 equations from the question first
x is the number of pints for type 1
y is the number of pints for type 2
The equation
x + y = 120
60% x + 85% y = 65% (x + y)
Solve the equation
From the 2nd equation
0.6x + 0.85y = 0.65(x + y)
0.6x + 0.85y = 0.65x + 0.65y
0.85y - 0.65y = 0.65x - 0.6x
0.2y = 0.05x
y = 4x
From the 1st equation
x + y = 120
x + 4x = 120
5x = 120
x = 24
y = 4x
y = 96
The first type should be 24 pints, the second type should be 96 pints
Answer 4
4multiplyed by 4 is 16
360 ft * 160ft = 57,600 ft squared
I'm not sure, this question was kind of confusing
