A community center charges x dollars for a summer activity if individuals are signed up before the day of the activity. Individuals who sign up the day of the activity are charged a fee of x plus 0.20 x dollars. Which expression also represents the fee for signing up the day of the activity, and what does it mean about the fee?

1.2 x; individuals signing up the day of the activity get charged 20% more

0.8 x; individuals signing up the day of the activity get charged 20% more

1.2 x; individuals signing up the day of the activity get charged 20% less

0.8 x; individuals signing up the day of the activity get charged 20% less

Answers

A is the answer to the question

The correct option will be "Option A."

It is given that a community center charges x dollars for a summer activity before the day of activity and on the day of activity they charge x plus 0.20x dollars.

We have to find the expression on day of activity and what is correct statement about the fee.

What will be the value if we add x with 2x ?

The value will be 3x.

Let's translate the problem to an equation we can work with:-

Before the day of activity, fee = x

On the day of activity fee will be ,

x + 0.2x

Because x and 0.2x are both in terms of the same variable x, we can add them together:

1.2x = fee on the day-of-activity

So, individuals signing up the day-of the activity are charged 1.2x and because 20% of 1 is 0.2, individuals are charged 20% more on the day-of-activity.

Thus , the correct option is "option A".

Aaliyah measured a line to be 8.7 inches long. If the actual length of the line is 8.3 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?

Answers

The correct answer you are looking for is B

The Percent Error of the measurement is 4.59%.

What is Percent Error?

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.

Given:

Aaliyah measured a line to be 8.7 inches long.

If the actual length of the line is 8.3 inches.

So, the Percent Error

=  | (approx - exact) ÷ approx | x 100

= 8.7 - 8.3)/ 8.7 x 100

= 0.4/ 8.7 x 100

= 4.59

The Georgia Bulldogs football team are assessed 10-yard penalties 14 times during a football game. Which equation models the total number of yards the team lost in the game?

C. (-14)(-10) = 140 yards
D. (-14)(10) = -24 yards

Answers

It should be b because if they lost 10 years each time. It would be -10 yards times 14 because if you made the 14 negative it would cancel out so it would be 140 yards and that would seem like they’re earning 140 yards

Jared runs 1/4 mile long.Today,Jared ran 6 times around the track in 13 1/2 minutes.Did Jared run faster or slower than 6 miles per hour today?

Answers

Answer:

Step-by-step explanation:

he ran like the wind lol

Jared runs faster than 6 miles per hour today.

What is Average speed?

Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.

Jared runs 1/4 mile long.

Today, he ran 6 times around the track in 13 1/2 minutes.

Total distance traveled by him = 1/4 × 6 = 6/4 mile

Total time = 13 1/2 minutes = 27/2 minutes = (27/2)/60 = 27/2 × 1/60 = 9/40 hour

Average speed = Total distance/Time

Average speed = (6/4)/(9/40)

Reciprocal the term of denominator,

Average speed = (6/4) × (40/9)

Apply the multiplication operation, and we get

Average speed = 20/3 = 6.67 miles per hour

Thus, Jared runs faster than 6 miles per hour.

plz tell me what y + 4 = ½ (x – 4) is in standard form of a linear equation this is my 3rd question about it i need it plz

Answers

Answer:

1/2x - y = 6

Step-by-step explanation:

First, distribute 1/2 to the parentheses:

y + 4 = ½ (x – 4)

y + 4 = 1/2x - 2

Then, subtract y from both sides:

4 = 1/2x - y - 2

Add 2 to both sides:

6 = 1/2x - y

Reorder the equation:

1/2x - y = 6 is the standard form of the equation
