Stefan sells Jin a bicycle for ​$176 and a helmet for ​$16. The total cost for Jin is ​160% of what Stefan spent originally to b
Elis [28]

Answer:

Stefan originally paid $120 for the bicycle and helmet.

He made $72 by selling them to Jin.

Step-by-step explanation:

Given that:

Selling price of bicycle = $176

Selling price of helmet = $16

Total price = 176+16 = $192

This is 160% of what Stefan paid originally.

Let,

x be the original amount paid by Stefan.

160% of x = 192

\frac{160}{100}x=192\\1.6x=192

Dividing both sides by 1.6

\frac{1.6x}{1.6}=\frac{192}{1.6}\\x=120

Original amount paid by Stefan = $120

Profit = 192 - 120 = $72

Hence

Stefan originally paid $120 for the bicycle and helmet.

He made $72 by selling them to Jin.

Look at the image below. What is the area of the triangle? units​
Mrrafil [7]

Answer:

7 Units^2

Step-by-step explanation:

If we add an exact copy of the triangle, we can make a parallelogram.

Then we can use the parallelogram's area to figure out the triangle's area.

Hint #22 / 4

The original triangle has \dfrac{1}{2}

2

1

​

start fraction, 1, divided by, 2, end fraction the area of the parallelogram we just made.

Hint #33 / 4

\begin{aligned} \text{Area of parallelogram} &= \text{base} \times \text{height}\\\\ \text{Area of triangle} &= \dfrac{1}{2} \times \text{base} \times \text{height}\\\\ &= \dfrac{1}{2} \times 7 \times 2\\\\ &= \dfrac{1}{2} \times 2 \times 7\\\\ &= 1 \times 7\\\\ &= 7 \end{aligned}

Hint #44 / 4

The triangle has an area of 777 units^2

Keller boat travels 24mph. find the rate of the river if she can travel 6 mi upstream. in the same amount of time she can go 10
nikitadnepr [17]
The <u>correct answer</u> is:

6 mph.

Explanation:

We will use the formula d = rt for this, where d is <u>distance</u>, r is <u>rate</u>, and t is <u>time</u>.

We know that the time for both distances is the same; this means we want to isolate t in our formula.  To do this, we will cancel r by dividing both sides:
d/r = rt/r
d/r = t

We will write an expression for the time upstream, an expression for the time downstream, and set them equal.

For the time upstream, the distance is 6 and the rate is 24-x; this gives us

\frac{6}{24-x}

For the time downstream, the distance is 10 and the rate is 24+x; this gives us 

\frac{10}{24+x}

Together, these give us the equation

\frac{6}{24-x}=\frac{10}{24+x}

We cross-multiply to solve this:
6(24+x) = 10(24-x)

Using the distributive property, we have
6*24 + 6*x = 10*24 - 10*x
144+6x = 240-10x

Adding 10x to each side,
144+6x+10x = 240-10x+10x
144+16x = 240

Subtract 144 from each side:
144+16x-144 = 240-144
16x = 96

Divide both sides by 16:
16x/16 = 96/16
x = 6
