3t/4=2p/5 solve for p
p=15t/8
p=1.875 tons of sand
4x+10y=-13...you have to add the variables that are the same and then subtract the 13 from 0
Answer:
h = V/y^2
Step-by-step explanation:
The volume of a right pyramid is given by the expression = Area of base × height.
Area of base = Area of square at the base
= y × y = y^2.
Now, we substitute these values:
V = y^2 × height
height = V/y^2
Answer:
200.96 feet
Step-by-step explanation:
We have a pool with a radius of 28 feet.
They also tell us that there is a path around the pool and its width is 4 feet.
Thus:
The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= (28 + 4) feet
= 32 feet
To find the length of the fence, we need to find the circumference of the outside of the pool path. The radius is then equal to 32 feet.
The circumference of the outer edge of the pool path would be equal to the perimeter.
p = 2 * pi * r
replacing
p = 2 * 3.14 * 32
p = 200.96 feet
therefore 200.96 feet are needed
Answer:
11: b = c - 0.5, where b is the bread and c is the cheese
12: h = b + 2, where h is the height and b is the base
13: p = 25b, where p is the plane ticket and b is the bus ticket
