Mr. Green wants to know how far he can run. He knows he can run 103,000 mm. How many miles can he run? Show all work if you want to receive credit.
I know the answer is 0.064 miles but I need the work!! help please
Answer:
1 Mile = 1609000 mm.
1.03 × 10^5 × 6.21371192237337 = 0.064 mile
103000 /1609344= 103000 mm.
Step-by-step explanation:
The beginning process is just to find the amount that mm = miles. After that you will move the decimal to then get 0.064 of a mile.
103,000 mm is 0.064 miles
So he can run 0.064 miles.
Given,
He can run = 103,000 mm
We need to find how many miles he can run.
How many mm in a mile?1 mile = 1609344 mm
Find how many miles is 103,000 mm.
We have,
1 mile = 1609344 mm
Multiplying both sides by 103,000
103,000 x 1 mile = 103,000 mm x 1609344
Divide both sides by 1609344
( 103,000 x 1 mile ) / 1609344 = (103,000 mm x 1609344) / 1609344
0.064 miles = 103,000 mm
This means 103,000 mm is 0.064 miles.
Thus 103,000 mm is 0.064 miles

What do u get when you Simplify -4x - x.
Answer:
-4x? whats the value to x?
Step-by-step explanation:
Solve the compound inequality. −5x≤−10 or 7x−21≥14
-5x ≤ -10
Divide both sides by -5
x ≥ 2
7x - 21 ≥ 14
Add 21 to both sides
7x ≥ 35
Divide both sides by 7
x ≥ 5

A concert hall has seven sections. Each section has 23 rules. Please roll has 14 seats. If the theater sells out pretty particular performance, how many people attended? If the average ticket sold for $20, how much was collected at the box office? Need to write an equation. Thanks
Answer:
The number of people that attended the performance = 2,254
Amount collected at box office = $45,080
Step-by-step explanation:
For the theater to sell out a performance, it means it was filled to the brim( completely filled)
We have 7 sections, with 23 rows each
The total number of rows will be 23 * 7 = 161 rows
Since each row has 14 seats, the total number of seats will be 161 * 14 = 2,254 seats
Secondly we want to know how much was collected at the box office given the average ticket price
The amount collected at the box office = Number of seats * average ticket price = 2,254 * 20 = $45,080

Directed line segment porque is shown on the coordinate plane. What are the coordinates of the point 1/3 of the way from point P(4,4) to point Q(-2,1)?
Answer: (2,3).
Step-by-step explanation:
We need to find the coordinates of the point 1/3 of the way from point P(4,4) to point Q(-2,1).
Let the point be A.
[tex]PA:PQ=1:3[/tex]
[tex]PA:AQ=PA:(PQ-PA)=1:(3-1)=1:2[/tex]
It means the point A divide the segment PQ in 1:2.
Section formula: If a point divide a segment is m:n.
[tex]\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
[tex]A=\left(\dfrac{1(-2)+2(4)}{1+2},\dfrac{1(1)+2(4)}{1+2}\right)[/tex]
[tex]A=\left(\dfrac{-2+8}{3},\dfrac{1+8}{3}\right)[/tex]
[tex]A=\left(\dfrac{6}{3},\dfrac{9}{3}\right)[/tex]
[tex]A=\left(2,3\right)[/tex]
Therefore, the required coordinates are (2,3).
Is 0.35217534 a rational
Answer: YES
Step-by-step explanation:
THREE WAYS TO DETERMINE:
If the number given is in integer, it is rational.
If the number given is fraction, it is rational.
If the number given is decimal, as long as it is terminating or repetitive decimal, it is rational. (Because then you can write it as a fraction which leads to the second point)
--------------------------------------------------------------
0.35217534
It is a terminating decimal, which fits the third point.
So it is rational.Hope this helps!! :)
