Answer:
B
Step-by-step explanation:
sum of angles in a triangle is 180
6n +1 +108+9n-4=180
15n = 180 -105
15n = 75
n= 75/15 = 5
Error Analysis: Henry incorrectly said the rate 1/2 over 1/4 can be written as the unit rate 1/8 pound per quart.
What is the correct unit rate? What was Henry's likely error?
Answer:
1/2 = 2/4 = 4/8
Step-by-step explanation:
his error was probably that he only change the denominator since there all even
It says Find out the value of x
Answer:
x=31, x=31, x=21.
Step-by-step explanation:
So for number 33, we see that 2x+28=90 degrees so you just simplify the equation to 2x=62, x=31.
For number 34, we see that 4x+56=180 (flat line), so we simplify the equation again and get 4x=124, x=31 degrees.
For number 35, according to the vertical angle theorem, 43=2x+1, so we simplify that too and we get 42=2x, 21=x, x=21.

Given m∥n, find the value of x.
Answer:
x = 20
Step-by-step explanation:
The 2 given angles are alternate interior angles and are congruent, thus
7x - 3 = 6x + 17 ( subtract 6x from both sides )
x - 3 = 17 ( add 3 to both sides )
x = 20

Answer:
m∠1 = 148° and m∠2 = 32°
Step-by-step explanation:
m∠1 + m∠2 = 180° (supplementary angles)
4x° + (x - 5)° = 180 (substitution)
4x + x - 5 = 180
5x - 5 = 180
5x = 185
x = 37
m∠1 = 4(37)° =148° and m∠2 = (37 - 5)° = 32°

The number of machine parts produced at a manufacturing plant is based on the number of parts made in a given day
and the number of hours worked. Let P = 14x + 100 give the number of parts that are produced since the start of the
shift and H = x be the number of hours that are to be worked that particular day. Create the equation that would give
the number of parts produced per hour.
Answer:
The equation that would give the number of parts produced per hour, [tex]P_H[/tex] is given as follows;
[tex]P_H[/tex] = P/H - 100/H
Step-by-step explanation:
The given parameters are;
The number of parts produced is given by the equation, P = 14·x + 100, where x represents the number of hours worked on a particular day
The number of hours worked = H
Therefore, we have;
P = 14·H + 100
At H = 0, P₀ = 100
At H = 1, P = 114
At H = 2, P = 128
Therefore, the rate of change of the number of parts produced with the number of hours spent = The number of parts produced per hour, ΔP/ΔH = [tex]P_H[/tex], is given as follows;
ΔP/ΔH = [tex]P_H[/tex] = (P - P₀)/(H - 0) = P/H - P₀/H = (128 - 100)/(2 - 0) = 14
∴ The number of parts produced per hour, [tex]P_H[/tex] = P/H - 100/H.

Answer:
The better deal is 8 for $7.50
4 of pack one=$25
2 of pack two=$15
Spent altogether= $40
Answer:
Which is the better deal? Pack of 8 is a better deal.
Buy 4 of Pack One: $24.40
Buy 2 of Pack Two: $11.90
How much did you spend altogether? $36.30
Step-by-step explanation:
Let's start with the Swag Bags. To figure out if something is a good price, divide the items inside of it by the price so you can get the $ per item and compare.
[tex]\frac{6.25}{6}[/tex] = $1.04 per item for Pack of 6
[tex]\frac{7.50}{8}[/tex] = $.94 per item for Pack of 8
Generally, saying "which item is the better deal" refers to which price per item is cheaper. In this case, Pack of 8 is a better deal.
Now, goodie bags.
Pack one costs $6.10 while Pack two costs $5.95.
"Buy 4 of Pack One: $" is asking for the price of 4 Pack Ones. To do this, you simply multiply the pack one price by 4, since you are buying 4 of them.
4 * 6.10 = $24.40
Same idea for Pack Two, just different price and different amount.
2 * 5.95 = $11.90
How much did you spend altogether? Add the total values for both goodie bag packs.
$24.40 + $11.90 = $36.30

The answer Is C
• When volleyballs are purchased, they are not fully inflated. A partially inflated
volleyball can be modeled by a sphere whose volume is approximately 180 in). After
being fully inflated, its volume is approximately 294 in. To the nearest tenth of an
inch, how much does the radius increase when the volleyball is fully inflated?
Answer:
The radius increase when the volleyball is fully inflated is 0.5
Step-by-step explanation:
Volume of Partially inflated volleyball = 180 in³
Volume of Full inflated volleyball = 294 in³
We need to find how much does the radius increase when the volleyball is fully inflated?
First we will find the radius of both Partially inflated and Full inflated volleyball. Then we will find increase in radius.
The formula for Volume of sphere is: [tex]Volume=\frac{4}{3}\pi r^3[/tex]
Finding Radius of Partially inflated volleyball
Volume = 180
Putting values and finding radius of Partially inflated volleyball
[tex]Volume=\frac{4}{3}\pi r^3\\180=\frac{4}{3}*3.14*r^3\\4.186r^3=180\\r^3=\frac{180}{4.186}\\r^3=43.0\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{47}\\r= 3.6[/tex]
So, radius of Partially inflated volleyball is r = 3.6
Finding Radius of Fully inflated volleyball
Volume = 294
Putting values and finding radius of Fully inflated volleyball
[tex]Volume=\frac{4}{3}\pi r^3\\294=\frac{4}{3}*3.14*r^3\\4.186\:r^3=294\\r^3=\frac{294}{4.186}\\r^3=70.23\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{70.23}\\r= 4.1[/tex]
So, radius of Partially inflated volleyball is r = 4.1
Now, finding increase in radius by subtracting radius of fully inflated volleyball with partially inflated volleyball
Increase in radius of Fully inflated volleyball = 4.1 - 3.6
Increase in radius of Fully inflated volleyball = 0.5
So, the radius increase when the volleyball is fully inflated is 0.5

Answer:
The measure of <TRU is 72 deg.
Step-by-step explanation:
<QRU is a right angle, so it measures 90 deg.
Since m<QRT = 18 deg, then m<TRU must be 72 deg since 72 + 18 = 90.
Answer: The measure of <TRU is 72 deg.

What is an equation of the line that passes through the point (4,-3) and is perpendicular to the line x-2y=2?
Answer: 2x+y+11=0
Step-by-step explanation:
The equation of given line is x-2y-2=0
Slope of given line is (m1)= - coefficient of x÷coefficient of y
m1= -1÷-2 =1÷2
Let slope of required line be m2.
Since the two lines are perpendicular,
So,
m1×m2= -1
or, 1÷2×m2 = -1
m2 = -2
The required line is passing through (4,-3)
Using two points slope form,
y-y1 = m(x-x1)
or, y-(-3)= -2(x+4)
or, y+3= -2x -8
or, 2x+y+3+8 = 0
2x+y+11 = 0 which is required equation of line.
