Answer:
They both have no possible solution.
Step-by-step explanation:
Don't know how to explain, but it's 100% right
The set of all output values for a function is called the range.
1. Formula for volume of a cone is: V = PI * r * h/3
Volume = PI * 1 * 5/3 = 5.24 cubic inches.
2. Formula for volume of a sphere is: V = 4/3 * PI * r^3
Volume = 4/3 * PI * 1^3 = 4.19 cubic inches.
Answer:
Step-by-step explanation:
Set up an equation, where x is the number of gallons of 60% antifreeze solution.
Represent the percentages of antifreeze with decimal values.
0.6x + 0.3(80) = 0.5(x + 80)
Simplify and solve for x:
0.6x + 24 = 0.5x + 40
0.1x = 16
x = 160
So, you have to mix 160 gallons of a 60% antifreeze solution
Answer:
<h2>1. V = 100 in³</h2><h2>2. h = 10 in</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:
<em>B</em><em> - base area</em>
<em>h</em><em> - height</em>
<em />
1. We have
<em>h = 5in, B = 20 in²</em>.
Substitute:
2. We have
<em>B = 20.7 in², V = 207 in³</em>.
Substitute:
<em>divide both sides by 20.7</em>
