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

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%.

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%.

Answer: thaths hard

Step-by-step explanation:

Answer:

The functions have the same initial value

Step-by-step explanation:

As you can see, tour 2 starts at the point (0,35). This is the cost with no people. Tour 1 one the other hand starts at (1,45), not zero. So since the rate of change/slope is 10. Subtract 10 from 45 and you get 35. The same starting point as tour 2.

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:

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!

Answer:

C 6 months

Step-by-step explanation:

since u pay 20$ to sign up u can subtract that from 170=150

and then to find how many months the member payed divide by 25 since its how much u pay each month to get 6 months

The number of months that gym member pay will be 6 months. Then the correct option is C.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

A gym charges its members a one-time $20.00 sign-up fee and $25.00 per month. The function rule f(x) = 25x + 20, where 'x' is the number of months.

If a gym member paid $170.00. Then the number of months that gym member pay will be given as,

170 = 25x + 20

170 - 20 = 25x

25x = 150

x = 6 months

The number of months that gym member pay will be 6 months. Then the correct option is C.

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.

Step-by-step explanation:

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.
