Answer:
20
Step-by-step explanation:
because -20 + -12 = 32 + -12 = 20
approximately 20
The exponential constant is an important mathematical constant and is given the symbol e. Its value is approximately 20. It has been found that this value occurs so frequently when mathematics is used to model physical and economic phenomena that it is convenient to write simply e, f and g.

Step-by-step explanation:
Marcus earned $230 for 40 hours of work. Phillip earned $192 for 32 hours of work. Are these pay rates proportional? Explain.
Answer:
No.
Step-by-step explanation:
Find ROC for Marcus and Phillip
Marcus
230/40 = $5.75 per hour
Phillip
192/32 = $6 per hour
$6 > $5.75
Answer:
These pay rates are not proportional
Step-by-step explanation:
Dividing 230 by 40 gave 5.75, so Marcus earns $5.75 per hour he works
However, dividing 192 by 32 gives 6, which shows that Phillip earns $6 per hour and $0.25 more than Marcus
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
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%.

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.
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.

Hey everyone, I suck at math so here's a question to the people who don't:
12x+(-4x+1)3
Answer:
24x+3
Step-by-step explanation:
Not sure if you're supposed to simpilfy or solve for x but I simplifyied it!
First you want to start with (-4x+1) which becomes 12x, so recreate the expression to 12x+12x+3. Then combine likes terms, 12x+12x=24x. Then you can't do anything with the 3 so it becomes 24x+3!
An English teacher reviewed 2 3 of an essay in 1 4 of an hour. At this rate, how many essays can she review in 1 hour?
Pls help me I've spent like an hour on this now
Answer: The English teacher can review 2 essays in one hour
Step-by-step explanation: ok so if she reviewed 2/3 in 1/4 of an hour then she only needs to do 1/3 which is 1/8 of an hour so she can do another 1/3 of another essay for 1/8 of an hour and both 1/3rds would get you another 1/4 of an hour so that's 2/4 of an hour gone she can review another 2/3rds of an essay and another 2/3rds and your answer is 6/3 and that is 2.
I don't know if that makes sense it sounded better in my head, hope this helps!

Answer:
80 minutes
Step-by-step explanation:
One wall takes 20 minutes, so 20×4=80 minutes.
Answer: 320 minutes
Step-by-step explanation:
1/4 of a wall takes 20 minutes, therefore one wall takes 80 minutes. Multiply that by 4 for 4 walls, and that becomes 320 minutes.

If Josh can read 18 pages in 40 minutes, how long will it take him to read 90 pages?
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.

Show your work for all of them
1. 105 = 4x please show your work
2. 3.08 + w = 5
3. x/8 =2
4.2u + 2u = 64
5. Is g = 2.5 a solution for 11.8 = 9.3 + g Yes or No
6. Is x = 30 a solution for 120 = 4x Yes or No
Answer:
1. x= 26 1/4 (If you divide 105 by 4 you get the answer)
2. w=1.92 (subtract 3.08 from 5 and you get that)
3. x=16 (16/8 simplifies into 2)
4. u=16 (2 times 16 is 32 and if you add 32 plus 32 you get 64)
5. Yes (subtract 9.3 from 11.8)
6. Yes (divide 120 by 4)
