Answer:
x = 20/49 units; P = 8 48/49 units
Step-by-step explanation:
All sides of a square are congruent.
That means that the two given side lengths are equal.
We set the two lengths equal and solve the equation for x.
5.5x = (1/5)(3x + 10)
Multiply both sides by 5.
27.5x = 3x + 10
Subtract 3x from both sides.
24.5x = 10
x = 10/24.5
x = 20/49
The perimeter of a square is 4s, where s is the length of a side.
P = 4s
= 4(5.5x)
= 4 * 5.5 * 20/49
= 22 * 20/49
= 440/49
= 8 48/49
Answer: x = 20/49 units; P = 8 48/49 units
Answer:
The volume of the cylinder is 25.12
Step-by-step explanation:
The width is the diameter in the circle of the base
radius = half of diameter
r = 2/2 = 1
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 8
π = 3.14
r = radius = 1
v = (π * r²) * h
we replace the unknowns with the values we know
v = (3.14 * (1)²) * 8
v = (3.14 * 1) * 8
v =3.14 * 8
v = 25.12
The volume of the cylinder is 25.12
A) The amount of change is .20 (20 cents) so we need to find what percent of $4.00 is .20...
4 * x = .20
x = .20/4 = .05
Multiply by 100 (move decimal 2 places to the right) to change decimal to percent.
.05 = 5% increase
b)The increase is .75. What percent of 3.00 is .75
3 * x = .75
x = .75/3
x = .25 x 100 = 25% increase
c) The amount of change is .75 but this time we are going from 3.75 to 3.00 so we find out what percent .75 is of 3.75.
3.75 * x = .75
x = .75/3.75
x = .20 x 100 = 20% decrease
Total amount = $80
Amount spent on Monday = 3/5 x 80 = $48
Amount remaining = $80 - $48 = $32
The money is spent over 5 days:
5 days = $32
1 day = $32 ÷ 5 = $6.40
Answer: She spent $6.40 on each of the 5 days.
