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 describes the relationship between the number of months x, and the total cost of membership f(x). If a gym member paid $170.00, for how many months did the gym member pay?

A. 4 months
B. 5 months
C. 6 months
D. 7 months

Answers

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.

What is the solution to the equation?

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.

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%.

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?

Answer:

The moon is a bit more than one-fourth (27 percent) the size of Earth, a much smaller ratio (1:4) than any other planets and their moons. Earth's moon is the fifth largest moon in the solar system. The moon's mean radius is 1,079.6 miles (1,737.5 kilometers).

Step-by-step explanation: Earth's moon is the brightest object in our night sky. It appears quite large, but that is only because it is the closest celestial body. The moon is a bit more than one-fourth (27 percent) the size of Earth, a much smaller ratio (1:4) than any other planets and their moons. Earth's moon is the fifth largest moon in the solar system.

The moon's mean radius is 1,079.6 miles (1,737.5 kilometers). Double those figures to get its diameter: 2,159.2 miles (3,475 km), less than a third the width of Earth. The moon's equatorial circumference is 6,783.5 miles (10,917 km).

"If Earth were the size of a nickel, the moon would be about as big as a coffee bean," according to NASA.

Marcus earned $230 for 40 hours of work. Phillip earned $192 for 32 hours of work. Are these pay rates proportional? Explain.

Answers

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

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

I think it’s 6 cups of chocolate chips.

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!!!
