Answer:
inches
Step-by-step explanation:
The total length of pipe is 10 2/3rd inches
It is cut into 8 equal pieces
We need to divide total length by 8 to get length of each piece. First, we have to convert mixed number (total length) to improper fraction by using formula shown below:
So,
Each piece length is:
So, each piece is inches
Answer:
total area = 217 m³
Step-by-step explanation:
area of the triangle
= 14 × 10
= 140 m²
area of a semicircle
= 1/2 × 22/7 × 7 × 7
= 77 m²
total area
= 140 + 77
= 217 m³
V<span>=(</span><span>4/</span><span>3)</span><span>πr^</span><span>3
R=radius
Diameter= 2 times R
so,
R=7 ft
plugging the values;
V=(4/3)(3.14)(7)^3
V=1436.02 Cubic feet</span>
Answer:
y = 5
Step-by-step explanation:
Subtract 2y from either side. It'll cancel out both of them. Then the equation is 8y = 40.
Divide both sides by 8 and you get y=5
Pretty sure that's right. I have a dad who has a math degree so I think it would be right because he helps me every time.
Answer:
No solution
Step-by-step explanation:
Substitution is done by substituting one equation into another. To begin solve one equation for a variable.
Substitute y=-4x+3 into -4x-y=-2.
-4x -(-4x + 3) = -2
-4x + 4x - 3 = -2
-3=-2
This is a false statement and there is no variable present anymore. This means the equations have no solution.
