Stefan sells Jin a bicycle for $114 and a helmet for $18. The total cost for Jin is 110% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make by selling the bicycle and helmet to Jin?
Stefan originally spent $

Answers

Answer 1

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

A backpack is on sale for 15% off the original price of $39.99. What is the sale price?

Answers

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

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?

Answers

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.

The retangular prism shows is made from cubs.Each cube is 1 cubic unit. What is the volume in cubic units

Answers

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

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%

Answers

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.

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?

Answers

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.
