Answer:
The missing value is 6!
Step-by-Step Explanation:
First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)
Now, we can write this as a function, where we can represent the missing value as 'x'.
[tex]4+5+13+x=28[/tex]
In order to get the missing value, we must solve the equation.
Step 1: Simplify.
[tex]4+5+13+x=28\\22+x=28[/tex]
Step 2: Subtract 22 from both sides.
[tex]22+x=28\\22+x-22=28-22\\x=6[/tex]
x is equal to 6, which means the missing volume of gas is 6!

Based on this relationship, how many stairs will Joaquin count by the 23rd level?
A. 165
B. 55
C. 756
D. 736
Answer:
D
Step-by-step explanation:
As soon as you see a number times 1 thats how you can find your unit rate, or constant of proportionality.
So since we know that we are going by 32's, we would do 32 23 times, in other words, 32x23
And when you use a CALCULATOR or pencil and paper you get D, which is 736 stairs

1. If Z2 measures 120°, what is the measure of Z1? Explain how you found the measure of 21.
Answer:
60
Step-by-step explanation:
Angles 1 and 2 are supplementary, which means that their sum is 180 degrees.
180 - 120 = 60
Angle 1 is 60 degrees
If Z2 measures 120°. We can see that Angles 1 and Angles 2 are supplementary. Therefore, Angle 1 is 60 degrees.
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles.
If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line.
Those two-two angles are two pairs of supplementary angles.
That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
If Z2 measures 120°
We can see that Angles 1 and Angles 2 are supplementary, which means that their sum is 180 degrees.
Angles 1 + Angles 2 = 180
Angles 1= 180 - 120
Angles 1 = 60
Therefore, Angle 1 is 60 degrees.

Step-by-step explanation:
On some days, Jardon travels from home directly to his
work. On other days, Jardon visits with his friend on his way
to work.
Approximately how much farther would Jardon travel by
walking from his home to his friend's house and then from
his friend's house to work than he would travel by walking
from his home directly to work?
Using the Pythagorean Theorem, it is found that he would travel 92 miles farther by walking from his home to his friend's house and then from his friend's house to work than he would travel by walking from his home directly to work.
The Pythagorean Theorem states that, on a right triangle, the length of the hypotenuse squared is the sum of the length of each leg squared, that is:
[tex]h^2 = l_1^2 + l_2^2[/tex]
Walking from his home to his friend's house and then from his friend's house to work, Jardon travels 240 + 120 = 360 yards.
Directly from his home to work, the distance is the hypotenuse of a right triangle with legs [tex]l_1 = 240, l_2 = 120[/tex], hence:
[tex]d^2 = 240^2 + 120^2[/tex]
[tex]d = \sqrt{240^2 + 120^2}[/tex]
[tex]d = 268[/tex]
360 - 268 = 92
He would travel 92 miles farther by walking from his home to his friend's house and then from his friend's house to work than he would travel by walking from his home directly to work.

Find the product of the expression:

Answer:
[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)=90x^{15}[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)[/tex]
Apply the exponent rule:
[tex]a^b\cdot \:a^c=a^{b+c}[/tex]
so the expression becomes
[tex]\left(3x^2\right)\:\left(5x^8\right)\:\left(6x^5\right)=3\cdot \:\:5\cdot \:\:6x^{2+8+5}[/tex]
Add the exponent numbers: 2+8+5=15
[tex]=3\cdot \:5\cdot \:6x^{15}[/tex]
Multiply the numbers: 3×5×6=90
[tex]=90x^{15}[/tex]
Therefore, we conclude that:

Write an equation for the line in standard form
Answer:
The equation of the line in standard form is y = -1/2·x - 3
Step-by-step explanation:
From the given graph, the "x" and "y" coordinates points through which the line of the graph passes are;
(-4, -1), (-2, -2), and (2, -4)
The slope, m, of the graph is given as follow;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, by substituting the values of the coordinates for two known points, we have;
[tex]Slope, \, m =\dfrac{(-4) -(-1)}{2-(-4)} = \dfrac{(-4) + 1}{2+4 } = \dfrac{-3}{6} = -\dfrac{1}{2}[/tex]
The slope of the graph, m = -1/2
The equation of the graph on point and slope form is given as follows;
y - (-4) = -1/2(x - 2)
y = -x/2 + 1 - 4 = -x/2 - 3
The equation of the line in standard form, y = m·x + c is y = -1/2·x - 3.

The pentagon is a regular polygon (all sides are equal). What is the Perimeter?
One side is 8x-10
Another side is 2(x+1)
Given:
One side = 8x-10
Another side = 2(x+1)
To find:
The perimeter of the pentagon.
Solution:
We know that, all five sides of a regular pentagon are equal.
[tex]8x-10=2(x+1)[/tex]
[tex]8x-10=2x+2[/tex]
[tex]8x-2x=10+2[/tex]
[tex]6x=12[/tex]
Divide both sides by6.
[tex]x=2[/tex]
Now, the length of each side of the pentagon is
[tex]Side=8(2)-10[/tex]
[tex]Side=16-10[/tex]
[tex]Side=6[/tex]
We know that, perimeter of a regular pentagon is
[tex]P=5a[/tex]
Where, a is the side length.
[tex]P=5(6)[/tex]
[tex]P=30[/tex]
Therefore, the perimeter of the regular pentagon is 30 units.

Where the above right triangle is given, note that the value of x when rounded to the nearest tenth is 19.2.
What is a right triangle?
A right triangle is a triangle with one angle measuring 90°, forming a perpendicular side.
In this case,the base is 9 and the height is 17. Using the Pythagorean theorem, we can calculate the length of the hypotenuse as follows:
x² = 9² + 17²
x²= 81 + 289
x² = 370
To find the value of x, we take the square root of both sides -
x = √370
x = 19.2353840617
x ≈ 19.2 (rounded to the nearest tenth)

If triangle DEF is congruent to triangle GJH, find each missing angle?
Answer
<F = 105°
<G = 41°
<J = 34°
GJ = 19m
JH =14m
GH = 16m
Step-by-step explanation:
Since triangle DEF is congruent to triangle GJH, the following are true
<D = <G
<E = <J
<F = <H
Given
<H = 105°
Hence <F = 105°
Also <E = 34° =<J
From ∆GHJ
<G+<H+<J = 180°
<G+105+34 = 180°
<G + 139 =180
<G= 180-139
<G = 41°
Get the sides. For the sides, the following are true
DE = GJ = 19m
Also EF =JH = 14m
DF =GH = 16m
Mr. Sanders teaches a painting class. He makes the histogram below to summarize the number of paintings each student has completed since the class began. Mr. Sanders says that the histogram shows that 1/3 of the students have finished 12 or more paintings.
Answer:
Step-by-step explanation:
6
2
2/3
Answer:
Mr Sanders likely found that 1/3 of students have completed 12 or more paintings because there are 6 bars on the histogram, and 2 of the bars represent students with 12 or more completed paintings. The actual fraction of the students who have completed 12 or more paintings is 4/19.
Step-by-step explanation:
There are 19 students in Mr Sanders's class. There are 6 bars on that histogram. He most likely thought that since the 2/6 is equal to 1/3, 1/3 of his students completed 12 or more paintings. That is not the case. Two-sixths/one-third isn't even a whole number. The other options are 2/3, 4/19, and 4/17. Two-thirds and four-seventeenths are not whole numbers as well. So that leaves 4/19. Four-nineteenths is actually equal to the whole number 4. We must put 4/19 as our answer because there are no such things as partial students...
