Answer:
$12
Step-by-step explanation:
given:
Stefan sells jin a bicycle for $114 and a helmet for $18.
we're gonna add to get the total cost 114 + 18 = $132
The total cost is 110% of what he spent originally to buy the bike and helmet.
divide 110% by 100 to get the answer in decimal which if you calculate is 1.1
now we're gonna make a simple equation and assume what Stefan spends originally is x
1.1 * x = 132
1.1x = 132
(now we want x to be alone so we can find its value so divide both sides by 1.1 (division is the opposite of multiplication if, for example, we have 1.1 - x 1.1 is positive so take it to the other side it'll be negative))
after dividing x=120
therefore, he originally spent $120
and to find how much money Stefan made we're gonna subtract 132-120 = $12
Stefan made $12

Which color's observed frequency is closest to its expected frequency?
red
blue
green
O yellow
Answer:
Blue
Step-by-step explanation:
Expected frequency is:
red 10/40 = 1/4 = 0.25 = 25%
blue 10/40 = 1/4 = 0.25 = 25%
yellow 10/40 = 1/4 = 0.25 = 25%
green 10/40 = 1/4 = 0.25 = 25%
Observed Frequency is:
red 1/7 = 0.14 = 14%
blue 2/7 = 0.28 = 28% √
yellow 4/7 = 0.57 = 57%
green 0/7 = 0.00 = 0%

The retangular prism shows is made from cubs.Each cube is 1 cubic unit. What is the volume in cubic units
Answer:
72 square units
Step-by-step explanation:
To get these, we will use the attached diagram as a case study
Since each cube is 1cubic unit, hence the length of the side of a cube is 1unit
From the diagram
Length = 6units
Width = 3 units
Height = 4units
Volume of the prism = Length * Width * Height
Volume of the prism = 6 * 3 * 4
Volume of the prism = 18 * 4
Volume of the prism = 72 sq.units
Hence the volume of the prism is 72 square units
If the student is a domain/inout and the hair color is the range/output how is these two set of relation not a function?
Answer:
A function is a relation that maps inputs from a set called the domain, into outputs from a set called the range.
Such that each input can be mapped into only one output.
So for example, if we have a relation that maps the input 2 into two different values:
f(2) = 4
f(2) = 8
Then this is not a function.
In the case of the problem, we have a student as the input, and the hair color as the output.
So we will have something like:
f(student) = blond
And if this student decides to change his/her hair color to red?
Then the function becomes:
f(student) = red
So for the same input, we had two different outputs, which means that this is not a function.
We also could have the case where a given student has two colors (Californian for example)
Where again, we would see two different outputs for one single input.
Peter says that 3/4 of a pizza is always the same as 6/8 of a pizza. Nadia says that while they are equivalent fractions, 3/4 and 6/8 of a pizza could represent different amounts. Use a counter example to explain who is correct. Please I need your help. If you help you are nice and god will protect you forever.
Answer:
Nadia
Step-by-step explanation:
6/8 is 3/4 and both are 75% of a pizza but, the eighths of a pizza is a smaller slice of pizza.
4/4 is four slices of pizza
8/8 is eight slices of pizza
They are different amounts.

Damien deposited $250 in an account that earned 3.75% interest compounded annually. He did not make additional deposits or withdrawals. What will be the balance in this account at the end of 4 years? $127.26 $287.50 $289.66 $370.50
Answer:
$289.66
Step-by-step explanation:
A=P(1+r)^t
P=250
r= .0375
t= 4
A=250(1+.0375)^4
A= 289.66
$ 289.66 will be the balance at the end of the 4 years.
What is compound interest?One of the most important ideas in finance is compound interest, which means that the interest you earn each year is added to your principal and grows at a growing rate. It serves as the foundation for everything from a personal savings strategy to long-term stock market development. It also takes into consideration the effects of inflation and the relevance of debt repayment.
Given, Damien deposited $250 in an account that earned 3.75% interest compounded yearly. Hence,
principal amount = 250
rate = 3.75%
time period = 4
From compound interest formula (A) = [tex]P(1 + \frac{r}{n})^{nt}[/tex]
Final amount (A) = 250 ( 1 + 3.75/ 1)^4 = 289.66
Therefore Damien will have 283.66$ at the end of the four years.

A backpack is on sale for 15% off the original price of $39.99. What is the sale price?
Answer:
33.99
Step-by-step explanation:
multiply the original by 100-the sale percentage
(100-15 = 85
.85x39.99
Answer:
$33.99
Step-by-step explanation:
We are given that we have 15%.
What this means is that we subtract 15% from 100%.
Doing that we get 1.00 - 0.15 = 0.85
Therefore the price equals $39.99 * 0.85
The final price is $33.99

Triangle GHK has an area of m square units. If the height of the triangle is increased to five times the current height, and the length of the base increased to four times the current length, what will be the area of the larger triangle?
Answer:
20m square units
Step-by-step explanation:
The area of a traingle = bh/2............... Equation 1
Where b = lenght of the base, h = heigt of the triangle.
From the question,
The area of triangle GHK = m square units., let the base and the heigth of the triangle be x and y respectively
Therefore,
b = x, h = y
Substitute these values into equation 1
m = xy/2................... Equation 2
If the height of the triangle increase to five times the current height, and the length of the base increase to four times the current length.
Therefore,
height of the larger triangle = 5y, base of the larger triangle = 4x
Substitute these values into equation 1
Area of the larger triangle = (5y×4x)/2
Area of the larger triangle = 20xy/2................. Equation 3
Substitute equation 2 into equation 3
Area of the new triangle = 20m square units.
