A mile is 5, 280 feet long. A certain indoor gym has a running track for which 12 laps around the track is equivalent to 1 mile. Explain how you can use partial quotients to determine
how many feet long the track is
X
Hint
1 of 2
Dividing by partial quotients means subtracting multiples of the divisor from the dividend until there is nothing left to subtract.
First, I would use
and subtract
Then I would use
X
in order to decrease the dividend to 0.
Adding the partial quotients
and
gives the whole-number quotient,
The track is 440 feet long.
Answer:
440 feet
Step-by-step explanation:
The relationship between mile and feet is given as:
1 mile = 5280 feet.
The length of 12 laps around the track is equivalent to 1 mile:
12 laps = 1 mile
Dividing both sides by 12 and simplifying:
12 laps / 12 = 1 mile / 12
1 lap = (1/12) mile
This means that the relationship between the length of the track and feet is given as:
Length of track = (1/12) × 5280 feet
Simplifying the expression:
Length of track = 440 feet

Jill is using a map of her town to determine how far the park is from school. The map does not have a scale, but Jill knows her school is 3 miles from home. On the map, the distance between home and school measures 1.5 inches. If the park is 2.5 inches from the school on the map, what is the actual distance in miles?
Answer:
The answer is five miles.
Step-by-step explanation:
Here’s one way to solve this problem.
First, write the ratio of the known distance on the map to the corresponding actual distance, one point five inches over three miles.
Next, choose a variable, such as d, to represent the unknown distance between the school and the park.
Then, write the ratio of the distance from the park to the school on the map to the corresponding actual distance, two point five inches over d miles.
Next, write a proportion equating the two ratios.
Now, cross multiply.
Finally, divide both sides by one point five to arrive at the actual distance, five miles.
So, the actual distance between the park and the school is five miles.
Answer:
5 miles!

Write a rule that would allow you to test whether (x,y) is on line ℓ.
Answer:
We have a line L.
Remember that in two dimensions, we can write a line as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
And then using one of these points, we can find the value of b.
Then wen we got the equation for the line:
y = a*x + b
We can input a point (x, y)
And see if the equality is true, then the point belongs to the line L.

so the third answer
Step-by-step explanation:
Write the standard form of the equation of the line that passes through (-2, -3) and (2, -5).
the slope is 6-2/2-(-2)=4/4=1
point slope form: y-6=1(x-2)
slope-intercept form: y=x+4
Standard form: -x+y=4 change to x-y=-4

A concert charges $30 admission and $15 per shirt. Alyssa paid $75 at the concert for her admission and shirts. Write and solve an equation to find the number of shirts Alyssa bought. Explain what your variable represents.
Answer:
75-30/15=x
Step-by-step explanation:
75-30=45
45/15=3
75-30/15=x
Answer:
30+15(x)=75 so x would =3
Step-by-step explanation:
So you have one ticket which is $30, then you add 15 times however many shirts she buys which in total will equal $75. She would have bought 3 shirts. So 30+ 15(3)=75. Hope that helps!

Internet Usage The number of hours people in the United States
spent using the Internet each year from 1998 to 2001 can be
modeled by the function f(x) 5 26.4x 1 54.4 where x is the number
of years since 1998.
a. Graph the function and identify its domain and range.
b. Find the number of hours that people spent on the Internet
in 2000. Explain how you found your answer.
c. When did people spend about 120 hours per year on the
Internet? Explain how you found your answer.
Answer:
Look in picture
Step-by-step explanation:
Functions can be represented on graph and as equation.
The domain and the range of the function are [0,3] and [54.4,133.6]The number of hours spent in 2000 is 107.2People spend about 120 hours per year in 2001The function is given as:
[tex]f(x) = 26.4x + 54.4[/tex]
(a) The graph, domain and range
See attachment for the graph of [tex]f(x) = 26.4x + 54.4[/tex]
The function represents years from 1998 to 2001.
This means that:
[tex]x = 0[/tex] in 1998 and [tex]x =3[/tex] in 2001
So, the domain is: [tex][0, 3][/tex]
From the graph;
[tex]x = 0 \to f(x) = 54.4[/tex]
[tex]x = 3 \to f(x) = 133.6[/tex]
So, the range is [tex][54.4,133.6][/tex]
(b) Number of hours spent in 2000
First, we calculate x.
[tex]x = 2000 - 1998[/tex]
[tex]x =2[/tex] i.e. 2 years since 1998
So, we have:
[tex]f(x) = 26.4x + 54.4[/tex]
[tex]f(2) =26.4 \times 2 + 54.4[/tex]
[tex]f(2) =107.2[/tex]
(c) When people starts to spend 120 hours.
We have:
[tex]f(x) = 26.4x + 54.4[/tex]
Substitute 120 for f(x)
[tex]120 = 26.4x + 54.4[/tex]
Collect like terms
[tex]26.4x = 120 - 54.4[/tex]
[tex]26.4x = 65.6[/tex]
Solve for x
[tex]x = \frac{65.6}{26.4}[/tex]
[tex]x = 2.48[/tex]
Round 2.48 to the smallest integer greater than 2.48
[tex]x = 3[/tex]
This represents the number of years, since 1998.
So, the actual year is:
[tex]Year =1998 + 3[/tex]
[tex]Year = 2001[/tex]
Hence, people spend about 120 hours per year in 2001

Quan makes $72 a day as an Uber driver, plus $8 for each client he has. If
Quan typically makes $104 a day. How many clients does he usually have
Answer:
Quan usually has 4 clients
Step-by-step explanation:
Working backward at math is to start with the final situation and work back one step at a time to get to the beginning.
We know Quan makes $104 a day, including his $72 fixed rate plus an $8 rate per client.
Subtracting the total and the fixed rate, we can find the variable part of his earnings.
$104 - $72 = $32
Quan usually makes $32 for the variable rate at $8 per client, thus he usually has $32 / $8 =4 clients.
Quan usually has 4 clients
