Answer:
x = 7
Step-by-step explanation:
First, multiple both sides by 5:
x + 3 = 10
Then, subtract both sides by 3:
x = 7
Answer:
The radius of cylinder is 8 inches.
Step-by-step explanation:
We have given,
Volume of cylinder = 320π cubic inches
Height of cylinder = 5 inches
We know, Formula for volume of cylinder as : V =πr²h
where r is radius of cylinder and h is the height of cylinder.
So, We can plug values for V and h to get radius of cylinder.
i.e V = πr²h
320π = πr²* 5
Solving for r.
We get,
320 = r² * 5
320/5 = r²
64 = r²
or r = ±8 , Since radius of cylinder can not a negative number so we neglect -8.
Hence the radius of cylinder is 8 inches.
2.5x2.75
= 6.875
6.875^2=47.27
Answer: 64 cm ²
Step-by-step explanation:
The perimeter of this rectangle will be:
= 2 * Length + 2 * Width
= 2 * 10 + 2 * 6
= 20 + 12
= 32 cm
The square has the same perimeter. Squares have 4 equal sides so each side of the square must be:
= 32 / 4
= 8 cm
Area = Length * Width
= 8 * 8
= 64 cm ²
Answer:
Step-by-step explanation:
<u>Points given:</u>
<u>Partition ratio: </u>
<u>Formula for the point:</u>
- x = x1 + a/(a+b)×(x2 - x1)
- y = y1 + a/(a +b)×(y2 - y1)
<u>So the points are:</u>
- x = 3 + 5/(5+3)×(7-3) = 3 + 5/8×4 = 5.5
- y = -3 + 5/8×(5 - (-3)) = -3 + 5/8×8= 2
