let's firstly convert the mixed fractions to improper fractions and then divide.
[tex]\bf \stackrel{mixed}{-4\frac{3}{5}}\implies \cfrac{-4\cdot 5+3}{5}\implies \stackrel{improper}{\cfrac{-23}{5}}~\hfill \stackrel{mixed}{1\frac{1}{5}}\implies \cfrac{1\cdot 5+1}{5}\implies \stackrel{improper}{\cfrac{6}{5}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{-23}{5}\div \cfrac{6}{5}\implies \cfrac{-23}{\begin{matrix} 5 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}}\cdot \cfrac{\begin{matrix} 5 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}}{6}\implies \cfrac{-23}{6}\implies -3\frac{5}{6}[/tex]
Okay I'm assuming this is a mixed fraction -4 ⅗ ÷ 11/5
First step get rid of the mixed fraction.
4 multiplied by 5 is 20 then you add 3 and you get 23
Next step cross cancel
-23 times 11 equals -23
5 5 11
improper fraction so convert to mixed number
answer is -2 1/11

Gary works at a bakery, and he needs to select a rectangular cookie sheet with an area of 192 square inches. The area of the cookie sheet is represented by the expression given below.
[tex]x^{2} + 4x[/tex]
Complete the given statements, and find the width of the cookie sheet.
The answers are:
Second step:
First box, 4
Second box,
The width is:
[tex]x+4[/tex]
Fourth step:
Box, 16
The length cant be -16in, the length is 12in, and the width is 16in.
Why?To solve the problem, we are using the formula to calculate the area of a rectangle, however, since the dimensions of the rectangle are not constant numbers, we will work with the variable "x", also, we know that the area of the cookie sheet is equal to 192 square inches.
So, solving we have:
First step:
We have the expression:
[tex]x^{2} +x[/tex]
Which is equal to: [tex]192in^{2}[/tex]
So,
[tex]x^{2} +4x=492[/tex]
Second step:
We have that the common factor of the left side of the equation is "x", so, we can simplify the expression in the following way:
[tex]x(x+4)=492[/tex]
Now, using the formula to calculate the area of a rectangle, we have:
[tex]length*width=Area\\\\length*width=92in^{2}\\\\x(x+4)=192in^{2}[/tex]
Where,
The length of the rectangle is "x"
The width of the rectangle is "x+4"
Third step:
Rewriting the expression, we have:
[tex]x^{2} +4x-192=0[/tex]
We need to find the roots (zeroes) of the quadratic function, in order to find the width of the rectangle without using the variable "x".
So, finding the values of "x" (roots or zeroes of the expression), we have:
[tex]x^{2} +4x-192=0[/tex]
Fourth step:
We need to find two numbers which it product gives as result the number -192 (including its sign) and their algebraic sum gives as result "4", those numbers are, -12 and 16,
[tex]-12*(16)=-192\\-12+16=4[/tex]
Then, rewriting the equation, we have:
[tex](x+16)(x-12)=0[/tex]
So, we that the expression is equal to 0 for two values of "x", these values are:
[tex]x_1=-16\\x_2=12[/tex]
Now, since the length can't be -16in, its equal to 12in.
[tex]length=x=12in[/tex]
[tex]length=12[/tex]
Then, from the second equation, we have that:
[tex]width=x+4[/tex]
Substituting "x" we can find the value of the width, so:
[tex]width=x+4=\\\\width=12+4=16in[/tex]
Hence, we have:
[tex]length=12in\\width=16in[/tex]

The number of sports drinks in a cooler during practice is modeled by the equation y=648-24x where y is the number of ounces in the cooler after practice and x is the number of players at the practice who take drinks from the cooler.
Part A
Based on the information in the equation, press the hotspots of three statements that are true.
Hint: 648 is the starting point.
-24 is the slope (rate of change).
The answers are:
B. Before practice, there are 648 ounces of sports drink in the cooler.
C. Each plater drinks approximately 24 ounces of sports drink at practice.
E. For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice.
Why?We are given the equation:
[tex]y=f(x)=648-24x[/tex]
Let's discard each of the given options in order to find the three correct options.
A. The cooler is meant to be used only by 24 players: False.
If we want to calculate how many players can use the cooler, we need to isolate "x" (rate of change) from the given equation, so, isolating we have:
[tex]f(x)=648-24x[/tex]
[tex]0=648-24x[/tex]
[tex]648=24x\\\\24x=648\\\\x=\frac{648}{24}=27[/tex]
We have that the cooler can be used by 27 players, so, the first option that states that "The cooler is meant to be used only by 24 players" is false.
B. Before practice, there are 648 ounces of sports drink in the cooler: True.
We have that before the practice when the cooler is not being used by any player (or there is no any player) has 648 ounces (full), we can calculate it making the variable "x" equal to 0, so, calculating we have:
[tex]f(x)=648-24x[/tex]
[tex]f(0)=648-24*(0)=648[/tex]
Therefore, we have that the statement "Before practice, there are 648 ounces of sports drink in the cooler." is true.
C. Each plater drinks approximately 24 ounces of sports drink at practice: True.
From the statement, we know that the rate of change is equal to (-24), and it's equal to the number of ounces that each player drinks.
Hence, we have that the statement "Each plater drinks approximately 24 ounces of sports drink at practice." is true.
D. If 24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink: False.
If we want to calculate the number of ounces that 24 players will drink, we need to use the slope value. If we know that each player drinks 24 ounces, so, to calculate how many ounces of sports drink will 24 players drink, we need to use the following equation:
[tex]DrankOunces=24oz*Players\\\\DrankOunces=24oz*24=576oz[/tex]
We have that 24 players will drink a total of 576 ounces, so, the statement "If 24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink." is false.
E. For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice: True.
From the statement and the equation, we know that the slope (rate of change) is negative, meaning that for each player (x) it will be 24 fewer ounces of sports drink after practice, for example, calculating for 1 and 2 players, we have:
[tex]f(1)=648-24*1=624[/tex]
[tex]f(x)=648-24*2=600[/tex]
We can see that for each player, it will be 24 fewer ounces of sports drink after practice.
Hence, we have that the statement "For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice." is true.
Therefore, the correct options are:
B. Before practice, there are 648 ounces of sports drink in the cooler.
C. Each plater drinks approximately 24 ounces of sports drink at practice.
E. For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice.

The table of values represents the function g(x) and the graph shows the function f(x).
The answer is:
The first and second options:
f(x) and g(x) intersect at exactly two points.
The x-intercepts of f(x) are common to g(x)
Why?To find the correct option (or options) , we need to remember the following:
- When a function intercepts the y-axis, it means that the "x" coordinate will be equal to 0.
- When a function intercepts the x-axis, it means that the "y" coordinate will be equal to 0.
Now, to find the correct option, we also need to compare the graphed function (f(x)) to the given table (g(x)).
So, discarding each of the given options to find the correct option, we have:
- First option, f(x) and g(x) intersect at exactly two points: True.
From the graph we can see that f(x) intercepts the x-axis at two points (-1,0) and (1,0), also, from the table we can see that g(x) intercepts the x-axis at the same two points (-1,0) and (1,0), it means that the functions intersect at exactly two points.
Hence, we have that f(x) and g(x) intersect at exactly two points.
- Second option, the x-intercepts of f(x) are common to g(x): True.
From the graph we can see that f(x) intercepts the x-axis at two points (-1,0) and (1,0), also, from the table we can see that g(x) intercepts the x-axis at the same two points (-1,0) and (1,0), so, both functions intercepts the x-axis at common points.
Hence,we have that the x-intercepts of f(x) are common to g(x)
- Third option, he minimum value of f(x) is less than the minimum value of g(x): False.
From the graph, we can see that the minimum value of f(x) is located at the point (0,-1), also, from the given table for g(x) we can see that there are values below the point (2,-3), meaning that the minimum value of f(x) is NOT less than the minimum value of g(x).
Hence, we have that the minimum value of f(x) is NOT less than the minimum value of g(x).
- Fourth option, f(x) and g(x) have the same y-intercept: False.
We can see that for the function f(x) the y-intercept is located at (0,-1) while from the given table, we can see the y-intercept for the function g(x) is located at (0,1)
Hence, we have that f(x) and g(x) have differents y-intercepts.
Therefore, the correct answers are:
The first and second options:
f(x) and g(x) intersect at exactly two points.
The x-intercepts of f(x) are common to g(x)
Have a nice day!
Note: I have attached an image for better understanding.
The graph of f(x) overlaps with the graph of g(x). Then the correct option is A.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function.
The table of values represents the function g(x) and the graph shows the function f(x).
The graph of f(x) overlaps with the graph of g(x).
Then the correct option is A.

Could the lengths 18 in., 80 in., and 82 in. be the side lengths of a right triangle?
Answer:
yes
Step-by-step explanation:
The formula to finding the hypotenuse of a right triangle is a^2+b^2=c^2. So since the longest side is the hypotenuse, the 82 in. is the hypotenuse. 18^2+80^2= 6724, then we square root it, square root of 6725 is 82.
Answer:
This is a right triangle
Step-by-step explanation:
We can check this using the Pythagorean theorem
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
18^2 + 80^2 = 82^2
324+6400=6724
6724 = 6724
True, so this is a right triangle
If the measure of arc AD = (6x – 80)° and 2G = (x + 2)°, what is the measure of G?
Answer:
The measure of G = 9.2°
Step-by-step explanation:
From the figure we can write,
The measure of <G is half the the measure of arc AD
To find the value of x
We have AD = (6x - 80)° and 2G = (x + 2)°
6x - 80 = (x + 2)
6x - 80 = x + 2
6x - x = 82
5x = 82
x = 82/5 = 16.4
To find the measure of <gG
m<G = (x + 2 )/2
= (16.4 + 2)/2 = 18.4 = 9.2
Therefore the measure of <G = 9.2°

3. A rocket is launched vertically from the ground with an initial velocity of 64 .
(a) Write a quadratic function that shows the height, in feet, of the rocket t seconds after it was launched.
(b) Graph on the coordinate plane.
(c) Use your graph from Part 3(b) to determine the rocket’s maximum height, the amount of time it took to reach its maximum height, and the amount of time it was in the air.
Answer:
(A): The equation is h(t)= -16t^2 + 64t
(B): The vertex points are (2,64) and the t intercepts are 0 and 4
(C): I dont know c!! i need help!
PLEASE EXPLAIN WELL!!!
a) The graph of the function is illustrated below.
b) The rocket's maximum height is 64 feet, it takes 2 seconds to reach this height.
c) The total time it was in the air is 4 seconds.
(A) Quadratic Function: To model the height of the rocket as it moves upward, we use a quadratic function in the form h(t) = at² + bt + c, where h(t) represents the height of the rocket at time t seconds. Since the rocket is moving vertically, we consider the acceleration due to gravity, which is -32 feet per second squared. The initial velocity of the rocket is 64 feet per second, so the coefficient of the linear term, b, is 64.
The equation for the height of the rocket is: h(t) = -16t² + 64t
(B) Graphing on the Coordinate Plane: To graph the quadratic function, we plot points on a coordinate plane. The vertex of the parabola represents the maximum height of the rocket, and the t-intercepts correspond to the times when the rocket hits the ground. The vertex of a quadratic function in the form h(t) = at² + bt + c is given by the coordinates (t_v, h(t_v)), where
t_v = -b / 2a.
In this case,
t_v = -64 / 2(-16) = 2 seconds.
(C) Finding Rocket's Maximum Height and Time in the Air: The vertex point we found earlier is (2, 64). This means that the rocket reaches its maximum height of 64 feet after 2 seconds of flight. To find the maximum height, we plug the value of t_v back into the equation:
h(t_v) = -16(2)² + 64(2) = -16(4) + 128 = 64 feet.
The rocket's maximum height is 64 feet, and it takes 2 seconds to reach this height. To find the total time the rocket is in the air, we look at the t-intercepts on the graph, which correspond to the times when the rocket hits the ground. From the equation h(t) = -16t² + 64t, we set h(t) to 0 and solve for t:
0 = -16t² + 64t t(0) = 0 (corresponding to the initial time of launch) t(4) = 4 seconds.
The rocket is in the air for 4 seconds.

use the system of equations and graphs below to complete the sentences
Answer:
Graph C; (2, 1)
Step-by-step explanation:
When equations are in standard form, finding the x- and y-intercepts is relatively easy. For ...
ax +by = c
x-intercept: c/ay-intercept: c/bUsing this idea on the first equation, we find its x-intercept to be -2. There is only one graph showing that has a line going through the point (-2, 0). That is Graph C. Checking the remaining intercepts for the two equations confirms that Graph C is the graph of this system of equations.
The two lines intersect at point (2, 1), so that is the solution to the system.
The correct graph is: Graph C
and the solution for this system is: (2,1)
Step-by-step explanation:The first equation is given by:
[tex]x-4y=-2-------(1)[/tex]
and the second equation is given by:
[tex]-2x-y=-5----------(2)[/tex]
from (1) we have:
[tex]x=-2+4y-------------(3)[/tex]
We put the value of x in equation (2) to get:
[tex]-2(-2+4y)-y=-5\\\\i.e.\\\\-2\times (-2)-2\times 4y-y=-5\\\\i.e.\\\\4-8y-y=-5\\\\i.e.\\\\4-9y=-5\\\\i.e.\\\\-9y=-5-4\\\\i.e.\\\\-9y=-9\\\\i.e.\\\\y=1[/tex]
Now on putting this value of y back to equation (3) we get:
[tex]x=-2+4\times 1\\\\x=-2+4\\\\x=2[/tex]
Hence, the solution to this system of equality is: (2,1)
someone please help me choose all answers that apply
First you must combine like terms (x and x)
2y + 2 + (x + x)
2y + 2 + 2x
^^^All have the number two in common so we can take a two out like so...
2 (y + 1 + x)
or
2(x + y + 1)
There fore the answer is A!
Hope this helped!
