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.

Please help The profit P, of a fundraising event can be modeled by the equation p= 50x-2000, where x is the number of tickets sold. What does the 50 in this expression represents?
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.

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%.

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.

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 solution

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.
