A man decides to buy a nice horse. He pays $60 for it, and he is very content with the strong animal. After a year, the value of the horse has increased to $70 and he decides to sell the horse. But already a few days later he regrets his decision to sell the beautiful horse, and he buys it again. Unfortunately he has to pay $80 to get it back, so he loses $10. After another year of owning the horse, he finally decides to sell the horse for $90. What is the overall profit the man makes?
Answers
Answer:
80!
Step-by-step explanation:
Goodluck!
Answer:
Horse Trade
Consider the trade-story as if it describes two separate trades, where:
In the first trade, the man buys something for $60 and sells it again for $70, so he makes a profit of $10.
In the second trade, the man buys something for $80 and sells it again for $90, so he makes again a profit of $10.
Conclusion: The man makes an overall profit of $10 + $10 = $20.
You can also look at the problem as follows: the total expenses are $60 + $80 = $140 and the total earnings are $70 + $90 = $160. The overall profit is therefore $160 - $140 = $20.

Jose bought 1.5 pounds of apples for $3.60.
How much would 34 of a pound of apples cost?
Enter your answer in the box.
Answers
Answer:
81.6
Step-by-step explanation:
If you do a table and find the unit rate by dividing 3.6/1.5. That gives you 2.4.
Now you multiply 2.4 (the price per pound) by 34 because that's how many pounds you need. You get 81.6
Answer:
$14.28
Step-by-step explanation:
1.5 / 3.60 = 0.42
0.42 * 34 = 14.28
you would divide the pounds by the money because you are trying to find 5e pounds per dollar. So then you get 0.42 the multiply that by 34 and you would get the answer of 34.

Mrs. Jackson earned a $500 bonus for signing a one-year contract to work as a nurse. Her salary is $22 per hour. If her first week’s check including the bonus is $1,204, how many hours did Mrs. Jackson work
Answers
Answer:
32 hours
Step-by-step explanation:
First setup an equation
500 + 22x = 1204 the x represents how many hours she worked an that is what we want to know. So to find out x you do this......
22x + 500 = 1204
1204-500= 704
704/22 = 32
So, X = 32 hours
Twenty percent of a mixture of pure milk and water is water. Half a litre of wine is added to one litre of the mixture of water and milk and throughly mixed. What percentage of the new mixture is water?
Answers
Answer:
In the new mixture, the percentage of water with respect to its total is 13.33%.
Step-by-step explanation:
Given that in a liter of mixture 20% of it was water and the remaining 80% was pure milk, and that half a liter of wine was added to that liter of mixture, to determine the percentage of water in the new mixture is necessary to perform the following calculation:
20 + 80 + 50 = 150
150 = 100
20 = X
((20 x 100) / 150) = X
2,000 / 150 = X
13.33 = X
Thus, in the new mixture, the percentage of water with respect to its total is 13.33%.
What expression is equivalent to 5 to the 6th power?PlZZZ HElP
Answers
Answer:
125.125
Step-by-step explanation:
i did it trust me
Using exponents, we know that expression (B) 125 × 125 is equivalent to the given expression 5⁶.
What are exponents?Exponentiation is a mathematical process that involves the base b and the exponent or power n. It is represented as bⁿ and is pronounced as "b to the n." The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself. For instance, the number 6 is multiplied by itself four times, yielding 6 6 6 6. You can write this as 6⁴. In this case, the exponent is 4 and the base is 6.So, 5⁶:
We know that 6 = 3 + 3:
Similarly,
5³⁺³We can say that:
5⁶ = 5³⁺³ = 5³ × 5³Now, simplify as follows:
5³ × 5³125 × 125Therefore, using exponents, we know that expression (B) 125 × 125 is equivalent to the given expression 5⁶.

Look at the system of equations in the box at
the right. Kevin stated that the equations in this system
have the same slope, so there will be infinitely many
solutions. Does Kevin's statement make sense?
Answers
Answer:
No.
Step-by-step explanation:
No, Kevin’s statement doesn’t make sense. He is correct that since the two equations have the same slope. Thus, they are parallel to each other.
However, since they are parallel, they will never touch. Therefore, there is no solution.
They will be infinitely many solutions if they are parallel and they have the same y-intercept.
Answer:
No it does not make sense
Step-by-step explanation:
If 2 linear equations have the same slope, then they represent two parallel linesParallel lines never cross, so they cannot have any solutionUse the graph below to graph the system of inequalities. Be sure to include your shading.

Answers
Answer: Nonlinear; power of x is greater than 1 (Bottom right corner)
Explanation:
The equation y = x^2 - 1 is known as a quadratic since the largest exponent here is 2. This equation cannot be written in slope intercept form y = mx+b, so that's why it's not linear. You can also graph y = x^2-1 to get a curved parabola. The graph must be a straight line if you want a linear equation.

A. The number of tickets sold
B. The number of people that attended
C. The profit from the event
D. The cost per ticket
Answers
Answer:
D. The cost per ticket
Step-by-step explanation:
You might remember that an equation in the form [tex]y=mx+b[/tex] is in slope-intercept form, where m is the slope and b is any number constant.For this equation, [tex]p=50x-2000[/tex] , y is p, the slope m is 50 and b is -2000The slope tells how much the profit is changing with each ticketSlope simply means "the amount of change"So if we have 2 tickets sold, the profit is [tex]p=50*100-2000=3000[/tex] What about 101? [tex]p=50*101-2000=3050[/tex] So the profit is changing by 50 with every ticketThat means each ticket costs 50 whatever currency It will save you trouble to just remember that in a profit equation, the slope is always the cost per item.Hey guys what is 2.009 to 2 significant figures please help.

Answers
Answer: a
Step-by-step explanation:
Jane has 34 candles leftover from the last craft show and Brianna
has 2 candles. They are making more candles for the next show.
Jane makes 24 candles per hour and Brianna makes 32 candles per
hour. They are also going to use the candles left over from the last
show and want to have the same number of candles at their stalls for
this show. Let h represent the number of hours they need to work
for this.
Answers
Answer:
4 hours
Step-by-step explanation:
Given that the number of leftover candles for Jane = 34
and the number of leftover candles for Brianna = 2
Rate of candle making for Jane = 24 candles/ hour
Rate of candle making for Jane = 32 candles/ hour
As they work for h hours to make candles.
So, in h hours, the number of new candles made by Jane = 24h candles
For Jane, the total number of candles after h houres, including the leftover candles [tex]= 24h+34 \cdots(i)[/tex]
Similarly, in h hours, the number of new candles made by Brianna = 32h candles
For Brianna, the total number of candles after h houres, including the leftover candles [tex]= 32h+2 \cdots(ii).[/tex]
As they want to have the same number of candles at their stalls, so equating the numbers of candles from equations (i) and (ii), we have
[tex]24h+34=32h+2 \\\\\Rightarrow 32h-24h=34-2 \\\\\Rightarrow 8h=32\\\\[/tex]
[tex]\Rightarrow h=32/8=4[/tex] hours.
Hence, both need to work for 4 hours to have the same number of candles.
