Find the quotient of 4 4/5 divided 4/5. Explain how you can use the GCF to write your answer I. Simplest form.
Answer:
5/4 Quotient[24/5] and 6
Step-by-step explanation:
5/4 Quotient[24/5]
Simplify the following:
(4 + 4/5)/(4/5)
Multiply the numerator of (4 + 4/5)/(4/5) by the reciprocal of the denominator. (4 + 4/5)/(4/5) = ((4 + 4/5)×5)/4:
((4 + 4/5)×5)/4
Put 4 + 4/5 over the common denominator 5. 4 + 4/5 = (5×4)/5 + 4/5:
(((5×4)/5 + 4/5) 5)/4
5×4 = 20:
((20/5 + 4/5)×5)/4
20/5 + 4/5 = (20 + 4)/5:
(((20 + 4)/5)×5)/4
20 + 4 = 24:
(24/5×5)/4
24/5×5 = (24×5)/5:
((24×5)/5)/4
((24×5)/5)/4 = (24×5)/(5×4):
(24×5)/(5×4)
(24×5)/(5×4) = 5/5×24/4 = 24/4:
24/4
The gcd of 24 and 4 is 4, so 24/4 = (4×6)/(4×1) = 4/4×6 = 6:

The relationship between money earned and hours worked is linear. Joe computes the slope between (4, 30) and (12, 90), then computes the slope between (4, 30) and (10, 75). How do the two slopes compare?
The slope between (4, 30) and (12, 90) is greater because the ordered pairs are farther apart on the x-axis.
The slope between (4, 30) and (12, 90) is greater because the ordered pairs are farther apart on the y-axis.
The slope between (4, 30) and (12, 90) and between (4, 30) and (10, 75) is the same.
The slope between (4, 30) and (12, 90) is less because 4 is a factor of 12 and 30 is a factor of 90.
The slope between (4, 30) and (12, 90) and between (4, 30) and (10, 75) is the same.
What is slope?Slope is the 'steepness' of the line, also commonly known as rise over run. slope is dividing the change in the y-value between two points over the change in the x-value.
given co-ordinates:
(4, 30), (10, 75), (12, 90), (22, 165)
Now, the slope between (4, 30) and (12, 90)
m= ( 90-30)/ (12-4)
m= 60 / 8
m = 7.5
and, the slope between (4, 30) and (10, 75)
m= ( 75-30)/ (10-4)
m=45 / 6
m= 7.5
Hence, The slope between (4, 30) and (12, 90) and between (4, 30) and (10, 75) is the same.

Last saturday 16 people worked the at the theater. four people worked the morning shift and 12 worked the evening shift. they earned a total of $1,080.00. what did they earn each?
Earning of each = $33.75
Let's take the earnings of each person to be x.
Total person working at the theater = 16 + 4 + 12
= 32
Now the total earnings of the people = 32x
Which is given = $1080
So we get an equation
32x = 1080
x = $33.75

1. At 2 p.m., a car is 100 km east of Toronto, driving eastward at 80 km/h. A truck leaves Toronto at 2 p.m. and is driving eastward at 120 km/h. At what time will the truck pass the car? How far east of Toronto will they be when this occurs?
The time at which the truck will pass the car is 2.5 hours and the distance at which the car and truck meet is 200km.
What is velocity?Velocity is defined as the ratio of the distance moved by the object at a particular time. The velocity is a vector quantity so it needs both the magnitude and the direction.
Given that at 2 p.m., a car is 100 km east of Toronto, driving eastward at 80 km/h. A truck leaves Toronto at 2 p.m. and is driving eastward at 120 km/h.
The time will be calculated as:-
Relative velocity = Distance / Time
Time = Distance / Relative velocity
Time = 100 / 120 - 80
Time = 2.5 Hours
Distance of car = Speed x time = 80 x 2.5
Distance of car = 80 x 2.5
Distance of car = 200 Km
Therefore, the time at which the truck will pass the car is 2.5 hours and the distance at which the car and truck meet is 200km.

Jeremy is 80 ft from a wall. Each time he moves toward the wall he reduces his distance from the wall by half. Which graph best models the situation?
the four photos are to this question
question 5
Which expressions describe the end behavior of the graph?
the 5 photo is to this one
Select EACH correct answer.
Using a geometric sequence, we have that:
Graph 1 models the situation.
The end behavior of the graph is given as follows:
As x decreases, y approaches the line y = 2.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q, hence the second term is the first multiplied by q, the third is the second multiplied by q, and so on.
For item 4, we have that:
The first term is of 80.The common ratio is of 0.5.Hence when x = 2, y = 40, when x = 3, y = 20, and so on.This means that the first graph is correct.
What is the end behavior of a function?The end behavior of a function is given by the limits of the function when x goes to infinity.
Hence, from the final graph, we have that:
As x decreases, y approaches the line y = 2. (lim x -> negative infinity = -2).As x increases, y decreases without bound. (lim x -> infinity = - infinity, not an option but just to explain).More can be learned about geometric sequences at https://brainly.com/question/24643676

we are calculating miles.
when we have speed, which is mph or miles/hour. what do we have to multiply it with to get miles ? hours !
miles/hour × hour = miles
so, in the function D(x) the speed 60 mph has to be multiplied by the hours spent driving to get the driven miles.
x = hours spent driving
the domain is the interval or set of all valid x (input) values. the range is the interval or set of all valid y (function result) values.
so what are valid x (number of driving hours) values ?
it starts with 0, if course (before actually driving). and it goes up to 4 (after 4 hours the 240 miles are "done").
the domain is
0 <= x <= 4
and the range ? that is all the function result values for the valid x values.
for x = 0 this starts at 240.
and goes down for x = 4 to 0.
the range is
0 <= y (= D(x)) <= 240

the volume of right circular cylinder a is 22 cubic centimeters. what is the volume, in cubic centimeters, of a right circular cylinder with twice the radius and half the height of cylinder a?
The new volume of the right circular cylinder is 44 cubic centimeter.
The formula for the volume of the cylinder is given as
V = Πr^2h (1)
We have been given that, V = 22 cubic centimeters
Now we need to find the volume of the cylinder which is denoted by V’ whose,
r = 2r
and, h = h/2
Now putting the required values in equation (1) we get
V’ = Π(2r)^2(h/2)
V’ = Π4r^2(h/2)
V’ = 4/2(Πr^2h)
V’ = 2V [as V = Πr^2h]
V’ = 2*22 cubic centimeter
V’ = 44 cubic centimeter

Joel, Ben, and Luke are each wearing a hat with a number on it. Each person adds the two numbers on the other two hats, giving totals of 11, 17, and 22. What is the largest number on a hat?
Solving a system of equations, we conclude that the largest number on a hat is 14.
What is the largest number on a hat?
We have 3 hats, each one with a number that we will define as:
x, y, and z.
We know that by adding pairs of these numbers we get 11, 17 and 22, then we can write a system of equations:
x + y = 11
x + z = 17
y + z = 22
Clearly z is the largest number, so we want to find z.
First, we can isolate x on the first equation so we get:
x = 11 - y
Replacing that in the second equation giveS:
x + z = 17
(11 - y) + z = 17
Now our system is:
y + z = 22
(11 - y) + z = 17
Isolating y in the first one we get:
y = 22 - z
Now we can replace that in the other equation:
(11 - (22 - z)) + z = 17
Now we can solve this for z.
11 - 22 + z + z = 17
-11 + 2z = 17
2z = 17 + 11 = 28
z = 28/2 = 14
z = 14
We conclude that the largest number on a hat is 14.

A> The equation for the line is y = -0.1x + 2600
B> The value of the car is $16,500
From the table, we know that for every 6000 miles added there is a decrease in the value by $600.
A> So it is the function of one order
y = kx + b
25500 = 5000k + b
24800 = 12000k + b
After equating it we get
b = 26000 and k = -0.1
Now put the value of b and k in the equation, and we get
y = -0.1x + 26000
Therefore the equation is y = -0.1 + 26000
B> When we put the value of x = 95000, we get
y = -0.1 × 95000 + 26000

If 4 is subtracted from the numerator of a fraction, its value becomes 1/3. If 5 is added to the denominator of the original fraction its value becomes 1/2. What is the original fraction.
Answer:
79
Step-by-step explanation:
Let the numerator of the original fraction be 'x' and the denominator be 'y'. So, the original fraction becomes xy
According to the question,
Condition I,
If 4 is subtracted from the numerator of a fraction, its value becomes 1/3.
or,x−4y=13
or,3(x−4)=y
or,y=3x−12
Condition II,
If 5 is added to the denominator of the original fraction, the value becomes 1/2.
or,xy+5=12
or,2x=y+5
Put value of y from equation (i) in equation (ii), we get,
or,2x=(3x−12)+5
or,2x=3x−12+5
or,3x−2x−7=0
∴x=7
Put value of x in equation (i), we get,
or,y=3×7−12
or,y=21−12
∴y=9
So, (x,y) = (7,9)
Therefore, the required original fraction is 79.
