If Josh can read 18 pages in 40 minutes, how long will it take him to read 90 pages?
Answers
Answer:
18=40
90? 40×90=3600÷18=200 pages.
Answer:
It will take him 200 minutes to read 90 pages.
Step-by-step explanation:
Josh can read 18 pages in 40 minutes.
Ratio of pages to minutes = 18 : 40
Number of pages to read = 90
Minutes = x
Ratio of pages to minutes = 90 : x
The relationship is proportional
18 : 40 :: 90 : x
Product of extremes = Product of means
18x = 40*90
18x = 3600
Dividing both sides by 18
[tex]\frac{18x}{18}=\frac{3600}{18}[/tex]
x = 200
Therefore,
It will take him 200 minutes to read 90 pages.

Plan a controlled experiment to investigate how an object’s position is related to the amount of its potential energy by measuring how high the ball bounces. Choose at least four heights from which you will drop the ball. The drop heights may be increased or decreased based on the bounciness of ball. Describe your experiment.
Answers
Answer:
Step-by-step explanation:
The height to which a ball will bounce depends on the height from which it is dropped, what the ball is made out of (and if it is inflated, what the pressure is), and what the surface it bounces from is made out of. The radius of the ball doesn't really matter, if you are measuring the height of the ball from the bottom of the ball to the ground.
A ball's gravitational potential energy is proportional to its height. At the bottom, just before the bounce, this energy is now all in the form of kinetic energy. After the bounce, the ball and the ground or floor have absorbed some of that energy and have become warmer and have made a noise. This energy lost in the bounce is a more or less constant fraction of the energy of the ball before the bounce. As the ball goes back up, kinetic energy (now a bit less) gets traded back for gravitational potential energy, and it will rise back to a height that is the original height times (1-fraction of energy lost). We'll call this number f. For a superball, f may be around 90% (0.9) or perhaps even bigger. For a steel ball on a thick steel plate, f is >0.95. For a properly inflated basketball, f is about 0.75. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. The steel ball on an unvarnished pine wood floor may not bounce at all, but rather make a dent, and so what the floor is made out of makes quite a lot of difference.

Answers
Answer:
128 bags of popcorn
Step-by-step explanation:
356.20 / 6.85 = 52
634/60 / 8.35 = 76
76 + 52 = 128
Answer: 52 bags of butter popcorn, 76 bags of caramel. Total of 128.

Find the percent of change. Round your answer to the nearest tenth of a percent, if
necessary.
a. Original price: $185
New price: $160
b. Original number of students: 56
New number of students: 77
Answers
Answer: a. 14% decrease or 86% of the whole
B. 137.5% increase
Step-by-step explanation:
A. Divide new price by old price and you get .86, change that to a percent by multiplying by 100. That equals 86%, the percent of change would be the difference of 100% to 86%, which is 14%
B. Use above explanation but don’t find the difference. 77/56= 1.375, 1.375*100=137.5
The percentage of decrement for case a will be around 13.52% and the increment in case b will be 37.5%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is equivalent to the quantity of that value between 1 and 100, and it is highly helpful for forecasting. For instance, if you say 678, we must also know the whole number, but if you say 80%, it is obvious.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Case a)
Given that
Original price: $185
New price: $160
% decrement = (change/original)100
% decrement = (185 - 160 )/185 × 100 ⇒ 13.52%
Case b)
The original number of students: 56
New number of students: 77
% increment = change/original × 100
% increment = (77 - 56)/56 × 100 ⇒ 37.5%
Hence the percentage change for case a) will be 13.52% and that of case b) will be 37.5%.

Jake's mom is making peanut butter cookies with chocolate chips. In her first batch, she used the ratio of 2:2 for the number of ups of chocolate chips to the number of cups of peanut butter chips. In her second batch, she used a ratio of 3:1 for the number of cups of chocolate chips to the number of cups of peanut butter chips and made the same number of cookies as the first batch. Jake made the following tape diagrams for his mom to reference. If her first batch used 4 cups of peanut butter chips, how many cups of chocolate chips did Jake's mom use for the second batch?
Answers
Explanation:
If in the first batch the ratio of 2 is 4 cups, that means that the ratio 1 would be 2 cups. In the second batch, the chocolate chip ratio was 3, so it would be 6 cups. I hope this helps!!!

Question 1- Y= -6x - 4
Question 2- -6
Step-by-step explanation:
If this is the original question, 12x + 2y = -8, you first need to move x to the right like so ----- 12x + 2y = -8
-12x - 12x
Leaving you with 2y = -12x -8. Then dived both sides by the Y coefficient ---------- 2y = -12x -8
/ 2 /2 /2
For the final answer---- Y = -6x -4
For question 2- Just take M from the top and put it in there ------- -6
Hope this helps. Comment below if you have any other questions. I'd be happy to explain!
12x+2y=-8
-12x on both sides
2y = -12x -8
/2 on both sides
y = -6x -4
