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.

Yoshi earns a commission of eight dollars on sales of $200 the amount of commission yes she earns is directly proportional to the sales what is the constant of proportionality of Yoshi sales commission
Answer:
k = constant of proportionality = 1/25
Step-by-step explanation:
Let
Amount of commission = x
Sales = y
Amount of commission she earns is directly proportional to the sales
x = k * y
Where,
k = constant of proportionality
what is the constant of proportionality of Yoshi sales commission
x = k * y
x = $8
y = $200
x = k * y
8 = k * 200
8 = 200k
k = 8/200
k = 1/25
k = constant of proportionality = 1/25
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)

Two quadratic functions are given. ()=−2−2+6 ()=22+5+3 Identify all values of x, to the nearest tenth, for which f (x) = g(x). A. –2.7 B. –1.8 C. –0.6 D. 0.4 E. 4.1 F. 5.1 G. 7.0
Answer:
[tex](a)\ x = 0.4\ or\ (d)\ x = -2.7[/tex]
Step-by-step explanation:
Given
[tex]f(x) = -x^2 - 2x +6[/tex]
[tex]g(x) = 2x^2 + 5x + 3[/tex]
Required
Find x if [tex]f(x) = g(x)[/tex]
The above implies that:
[tex]-x^2 -2x +6 = 2x^2 + 5x +3[/tex]
Collect like terms
[tex]2x^2 + x^2 + 5x + 2x + 3 - 6 = 0[/tex]
[tex]3x^2 + 7x - 3 = 0[/tex]
Using quadratic formula, we have;
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a=3; b=7; c=-3[/tex]
[tex]x = \frac{-7 \± \sqrt{7^2 - 4*3*-3}}{2*3}[/tex]
[tex]x = \frac{-7 \± \sqrt{49+ 36}}{6}[/tex]
[tex]x = \frac{-7 \± \sqrt{85}}{6}[/tex]
[tex]x = \frac{-7 \± 9.22}{6}[/tex]
Split
[tex]x = \frac{-7 + 9.22}{6}\ or\ x = \frac{-7 - 9.22}{6}[/tex]
[tex]x = \frac{2.22}{6}\ or\ x = \frac{-16.22}{6}[/tex]

The relative frequency that a randomly selected student's favorite exhibit was either butterflies or trains is 0.025.
What is the formula for calculating the joint relative frequency?Assume you need to compute the joint relative frequency of a certain category inside a larger category.
Then there's the proportion of that specific category's frequency to the total frequency of that large category.
The sum of all the frequency of the survey is;
⇒12+25+17+6
⇒60
The relative frequency for butterflies:
⇒12/60
⇒1/5
⇒0.25
The relative frequency for the train:
⇒6/60
⇒1/10
⇒0.1
The relative frequency that a randomly selected student's favorite exhibit was either butterflies or trains is;
⇒0.25×0.1
⇒0.025
Hence the relative frequency that a randomly selected student's favorite exhibit was either butterflies or trains is 0.025.

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.

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)
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:

10x = 74 - 54
10x = 20
x = 2
z° + 74° = 180° [Pair of supplementary angles]
