Answer:
LSA = 2πrH
Step-by-step explanation:
The lateral surface area of a cylinder is given by the formula as:
LSA = 2πrH
where, r and H are radius and height of the cylinder respectively.
The volume of cylinder is πr^2H
and Total surface are of cylinder = LSA+ 2× base are
= 2πrH +2πr^2
You can substitute any values of r and H to find LSA of the cylinder

A golf driving range charges a flat fee of $20 to practice and then $5.75 for a buckets of balls. Write an equation that models the charges (C) in terms of the number of bucket of balls (b) that you use
Answer:
A
Step-by-step explanation:
Flat fee is $20 [initial cost]
Each bucket of ball is $5.75
b is the number of buckets and c is the total cost
To get total cost, we add the flat fee with the bucket fee. Bucket fee is $5.75 multiplied by the number of buckets, which is b.
So, we have:
cost = $20 + $5.75b
In equation it is:
Choice A is right.
Ann works in a supermarket for $10.00 per hour. If her pay is increased to $12.00, then what is her percent increase in pay? Show your work.
Answer:
20% increase in her pay
Step-by-step explanation:
It's 20% increased, because it increased by $2, $2 goes into $10 5 times, and if you were to put that into percentages 2 is a fifth of 10 so that would 20%, because 20 is a fifth of 100.
Answer:
It's 20% increased,

When I divided I got 24.214286 so I rounded down to 24 pictures.
Eva buys a piece of red fabric that is 5.6 meters long and a piece of yellow fabric that is 2.8 meters long. How long are the two pieces of fabric together in millimeters?
Answer:
Total length of fabric pieces is 8400 mm.
Step-by-step explanation:
Eva buys a piece of red fabric of length = 5.6 meters
Since, 1 meter = 1000 mm
Therefor, 5.6 meter = 5.6 × 1000
= 5600 mm
Similarly, length of yellow fabric piece = 2.8 meters
≈ 2.8 × 1000 mm
≈ 2800 mm
If these pieces are joined together, total length of the fabric pieces
= 5600 + 2800
= 8400 mm
Therefore, total length of fabric pieces is 8400 mm.

What is the area of a circular pool with a diameter of 20 feet? Use 3.14
for pi and round your answer to the nearest hundredth.
Answer:
314
Step-by-step explanation:
To find the area of a circle using the diameter, use this formula:
[tex]A=\frac{1}{4}\pi d^2[/tex]
Substitute the diameter and the value of pi:
[tex]A = \frac{1}{4}*(3.14) * (20)^2[/tex]
[tex]A = 0.785 * 400[/tex]
A = 314
n a family vacation, Amy’s dad drove the car at a constant speed and traveled 585 miles in 13 hours. At this rate, how long would it have taken the family to travel 810 miles? What was the car’s rate of speed
Answer: 18 hours

A building in the shape of a cube has a width of 30 ft., a length of 30 ft., and a height of 30 ft. An architect wants to build a scale model of the building that is 10% smaller in volume. What is the height of the new building?
Answer:
Step-by-step explanation:
The height of the scale model is 13.92 feet. (Rounding to the nearest hundredth).
Step-by-step explanation:
These are the measurements of the real building:
Height = 30 feet
Width = 30 feet
Length = 30 feet
Volume of the real building = 30 * 30 * 30 = 27,000 cubic feet
These are the measurements of the scale model:
Volume of the scale model = 10% of 27,000 cubic feet
Volume of the scale model = 0.1 * 27,000 = 2,700 cubic feet
Height = ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)
Width = ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)
Length =∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)
The height of the scale model is 13.92 feet.
Answer:
28,96 ft (round to the nearest hundreds)
Step-by-step explanation:
1) find the volume of the first cube
V = side^3 = 30^3 = 27000 ft^3
2) find the 10% of 27000
27000 / 0,1 = 2700
3) find the volume of the second cube
V = 27000- 2700 = 24300 ft^3
4) find the height
height = ∛24300 = 28,96 ft (round to the nearest hundreds)
The total mass of Fatin and Hanim is 68 kg. Fatin is 6 kg lighter than Hanim. Find their respective masses.
Answer:
Hatim=37kg, Fatin=31
Step-by-step explanation:
Hatim=x, Fatin=x-x
x+x-6=68
add 6 to both sides
x+x=74
2x=74
divide both sides by 2
x=37
put in 37 fo the values determined earlier
Hatim=37, Fatin=37-6
Hatim=37, Fatin=31
check by plugging in the values
37+31=68 (or 37+37-6=68, either one works)

Which of the following examples has a unit rate of 30 meters per second? Select all that apply. A) 90 meters in 5 seconds B) 90 meters in 3 seconds C) 120 meters in 6 seconds D) 150 meters in 5 seconds E) 240 meters in 6 seconds
The following examples have a unit rate of 30 meters per second:
B) 90 meters in 3 seconds.
D) 150 meters in 5 seconds.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
We have the unit rate of 30 meters per second.
A) 90 meters in 5 seconds.
The unit rate = 90/5 meters per second.
The unit rate = 18 meters per second.
B) 90 meters in 3 seconds.
The unit rate = 30 meters per second.
C) 120 meters in 6 seconds.
The unit rate = 20 meters per second.
D) 150 meters in 5 seconds.
The unit rate = 30 meters per second.
E) 240 meters in 6 seconds.
The unit rate = 40 meters per second.
Therefore, B and D have the unit rate of 30 meter per second.

Answer:
35.6 units
Step-by-step explanation:
By intersecting chords theorem:

10x = 256
x = 256/10
x = 25.6
AB = 10 + x
AB = 10 + 25.6
AB = 35.6
