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?
Answer:
1/4 x 6/1 equals 1 2/4.
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
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

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?
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

Step-by-step explanation:
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
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".

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he has 11 chairs left over. If he arranges the chairs in 4 rows of that same length, he has 19 left over. How many chairs does Liam have?
Answer:
35 chairs in all
Step-by-step explanation:
each row has 4 chairs as if 4 rows has 19 extra chairs and 6 rows has 11 there are 8 chairs in 2 rows which means 4 chairs are in 1.
so take 4 (rows) x 4 (chairs) and get 16
16 + 19 (leftover) and get 35
