The amount of the quarts of milk to prepare a pound of cheese in mixed number is 4 ¹³/₂₀.
What is the meaning of the term mixed number?The mixed number is a representation of both a whole number and a legal fraction. A whole number, one numerator, as well as a denominator are combined to create a mixed number.Creating mixed fractions from incorrect fractions.
Step 1: Divide this numerator by the denominator
Step 2: The quotient should be expressed as a whole number.
Step 3: Input the numerator and denominator as the remainder and the divisor, respectively.
For the given question,
The quantity of 4.65 quarts of milk to make a pound of cheese.
This can be written as-
= 465/100
Dived the numerator and denominator by 5
= 93/20
Write the value in mixed fraction as;
The remainder will be 13 after diving 93 with 20 and with quotient 4.
= 4 ¹³/₂₀.
Thus, the amount of the quarts of milk to prepare a pound of cheese is 4 ¹³/₂₀.

The total area of a polygon is 176 sq.ft. Find the value of x in the drawing
Answer:
x=6 ft
Explanation:
The given polygon is a trapezium in which:
• The parallel sides are a=16 ft and b=(16+2x) ft
,• The height, h = 8 ft
,• Area = 176 sq.ft.
The area of a trapezium is calculated using the formula:
[tex]\begin{gathered} A=\frac{1}{2}(a+b)h \\ a,b\text{ are the parallel sides} \\ h\text{ is the perpendicular height} \end{gathered}[/tex]Substitute all the known values:
[tex]\begin{gathered} 176=\frac{1}{2}\times8(16+16+2x) \\ 176=4(32+2x) \end{gathered}[/tex]Divide both sides by 4.
[tex]\begin{gathered} \frac{176}{4}=32+2x \\ 44=32+2x \end{gathered}[/tex]Subtract 32 from both sides:
[tex]\begin{gathered} 44-32=32-32+2x \\ 12=2x \end{gathered}[/tex]Divide both sides by 2.
[tex]\begin{gathered} \frac{12}{2}=\frac{2x}{2} \\ x=6\text{ feet} \end{gathered}[/tex]The value of x in the drawing is 6 feet.
Answer:
X=6
Step-by-step explanation:
First multiply 8 by 16 to get 128. Then subtract that from 176 to get 48. Then divide by to because there are two triangles to get 24, so each triangle is 24 square feet. Find a number that multiplied by 8 equals 48 (this will be x). The reason that I did this is because of the formula for area of a triangle (B*H/2=A). After you divide by 48 by 2 you will get 24. The number that was multiplied by 8 is x (x=6).

Answer:
$8.4
Explanation:
To find how much money you should leave for a tip, we need to find how much is 20% of $42. So, to calculate this, we need to multiply 42 by 20 and then divide by 100, so:
$42 x 20% = 42 x 20 / 100 = 840 / 100 = 8.4
Therefore, the answer is $8.4
Lin ran 234 miles in 2/5 of an hour. Noah ran 823 miles in 4/3 of an hour.Who ran faster, Noah or Lin?How far would Lin run in 1 hour?How far did Noah run in 1 hour?How long would it take Lin to run 1 mile at that rate?How long would it take Noah to run 1 mile at that rate?
Given:
• For Lin:
Distance = 234 miles
Time = 2/5 of an hour
• For Noah:
Distance = 823 miles
Time = 4/3 of an hour
Let's determine who ran faster.
Let's find the time of each runner by multplying by 60.
Where:
60 minutes = 1 hour
To determine the speed of each of them, apply the formula:
[tex]speed=\frac{dis\tan ce}{time}[/tex]• To find Lin's speed, we have:
[tex]\text{ Lin's sp}eed=\frac{dis\tan ce}{\text{time}}=\frac{234}{\frac{2}{5}\ast60}=\frac{234}{24}=9.75\text{ mph}[/tex]Therefore, Lin's speed is 9.75 miles per hour.

There will be 1,215,450 different random samples of four accounts are possible.
What is combination and permutation?There are two methods to calculate the number of ways a certain event can happen. Both are used in different circumstances, such as, when the order of arrangement does not matter we use the combination and when the order matters we use permutation.
Given,
Population size, N = 75
Sample size, n = 4
We have selected a random sample of 4 accounts in order to learn about the population because these accounts can not be repeated and can be in any order, so we will use combination without repetition. According to this, the number of ways by which n subjects can be chosen from N subjects are given by,
[tex]\frac{N}{n}[/tex] = [tex]\frac{N!}{n!(N-n)!}[/tex]
Therefore, required number of ways are,
= 75!/4!(75-4)!
= 75!/4!*71!
= 75*74*73*72*/4*3*2

The slope of this regression line is 0.8 .What does this tell you about the relationship between the amount of fertilizer and the height of the seedlings?
The slope of a line shows the relation between a unitary increment in the x-variable and the corresponding change in the y-variable.
In this case, the x-variable represents the amount of fertilizer, in grams, and the y-variable represents the height of the seedings, in cm.
Then, the slope of 0.8 means that when the x-variable increases in 1 unit, the y-variable increases 0.8 units. Or more specifically, for each additional gram of fertilizer used, the height of the seedings increases by about 0.8 cm on average.

Tell whether the following statement is always, sometimes, or never true for numbers greater than zero. Explain. In equivalent ratios, if the numerator of the first ratio is greater than the denominator of the first ratio, then the numerator of the second ratio is greater than the denominator of the second ratio.
Answer
The statement is always true.
Explanation
Since equivalent ratios reduce to essentially the same fundamental ratios, if the numerator of one of the ratios is greater than its denominator, then the numerator of each of the equivalent ratios must be greater than each of their corresponding denominators too.
So, this statement is always true!

Use the table of values for f and g below to find the indicated compositions. (f \circ g)(8) =Answerg(f(3))=Answerf(f(1))=Answer (g \circ g)(6) =Answer
In order to find the value of a composition of functions at x = a, (f º g)(a), we first find the value of g(a), then find the value of f(x) at x = g(a).
(f º g)(a) = f(g(a))
In this problem, the values of f(x) and g(x) are shown in the table, for integer values of x from 0 to 9.
So, we have:
1. (f º g)(8) = f(g(8))
From the table, we see that
g(8) = 4 (value of g(x) in the line corresponding to x = 8)
Then:
f(g(8)) = f(4) = 4 (value of f(x) in the line corresponding to x = 4)
Thus:
[tex]\mleft(f\circ g\mright)\mleft(8\mright)=4[/tex]2. g(f(3))
f(3) = 8
g(8) = 4
Thus:

f(6) = 2
Thus:
[tex]f(f(1))=2[/tex]4. (g º g)(6) = g(g(6))

what do you do after you multiply an equation in the elimination method?2x -3y=-11x+3y = 8
1) Let's multiply the second equation by -2, to eliminate x
2x -3y=-11
x+3y = 8
2) Now let's add both equations
2x -3y=-11
-2x-6y = -16
--------------------
-9y = -27
3) Divide both by -9
y=3
4) Plug y=3 into the simpler original equation, to make calculations easier:
x +3y=8
x+3(3) =8
x +9 =8 Subtract 9 from both sides
x = 8-9
x=-1
So, after multiplying it we add both equations to eliminate one variable either x or y.
