Answer:
2
Step-by-step explanation:
Diameter = 14
Radius = 7 inches
Volume = (4/3)×3.14×7³ = 1436.026667 inches³
1436.026667 ÷ 693 = 2.072187552
Use Pythagorean Theorem.
a^2 + b^2 = c^2
Substitute the numbers.
12^2 + b^2 = 20^2
144 + b^2 = 400
Subtract 144 from each side.
b^2 = 256
Take square root.
The answer is
b = 16
divide the 2m by 9 then the -5 by 9
giving 2m/9 - 5/9
The multiply choice were worth 4 points.
Gretchen= 18x+19
Ezia= 15x+31
So basically you can enter any number. At first I picked 3 and then I did the math and I got 73 points for Gretchen and 76 points for Ezia.
Then I pick four and then I got 91 points for them both. This is how I got the answer:
18x+19=15x+31
18(4)+19=15(4)+31
72+19=60+31
91=91
