Answers
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: Not entirely sure if I understand the question, but if I do, then x = 11
Step-by-step explanation:
We know 10x + 50 = 160
We can start by removing 50 from both sides. Then we get: 10x = 110
Then we can divide both sides by 10 and get:
x = 11

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.
Answers
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
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?
Answers
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)

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
Answers
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.

The total mass of Fatin and Hanim is 68 kg. Fatin is 6 kg lighter than Hanim. Find their respective masses.
Answers
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)
