Answer:
∠P = 39º
∠Q=120º
∠R = 21º
Step-by-step explanation:
m∠P+m∠Q+m∠R=180º (sum of ∠s in a triangle)
2x-3+6x-6+x=180º (substitution)
9x-9=180º (algebra)
9x=189º (algebra)
x=21º (algebra) (this is ∠R)
(2x-3)=39º (algebra) (this is ∠P)
6x-6=120º (algebra) (this is ∠Q)
Answer:
∠R = 21°
∠Q = 120°
∠P = 39°
Step-by-step explanation:
Step 1:
6x - 6° + 2x - 3° + x = 180° Sum of a Δ
Step 2:
9x - 9° = 180° Combine Like Terms
Step 3:
9x = 189° Add 9 on both sides
Step 4:
x = 189° ÷ 9 Divide
Step 5:
x = 21°
Step 6:
2 ( 21 ) - 3 = ∠P = 39°
Step 7:
6 ( 21 ) - 6 = ∠Q = 126°
Step 8:
∠R = 21°
Answer:
∠R = 21°
∠Q = 120°
∠P = 39°

Step-by-step explanation:
We can find her income by multiplying the number of customers by 606060, and then subtracting her fixed transportation cost to get her net gain:
Y=60X-5Y=60X−5Y, equals, 60, X, minus, 5
How will this transformation impact the mean and standard deviation?
Hint #22 / 4
Effect on mean
Multiplying by 606060 and subtracting 555 both impact the mean:
\begin{aligned} \mu_Y&=60\left(\mu_X\right)-5 \\\\ &=60\left(1.8\right)-5 \\\\ &=108-5 \\\\ &=103 \end{aligned}

Hint #33 / 4
Effect on standard deviation
Multiplying by 606060 impacts the standard deviation, but subtracting 555 does not — adding or subtracting a constant only shifts data, which doesn't affect the spread.
\begin{aligned} \sigma_Y&=60\left(\sigma_X\right) \\\\ &\approx60\left(1.08\right) \\\\ &\approx64.8 \end{aligned}

Answers
Answer:
b(a+2)(a-1)
Step-by-step explanation:
b(2a+a^2-2-2-a)
Answer:
b (a + 2) (a - 1)
Step-by-step explanation:
1. First you need to factor out b from the equation because it is the one factor that they all have in common.
2ab + a²b - 2b - ab
b (2a + a² - 2 - a)
2. Then you just factor 2a + a² - 2 - a and remember the b
b (2a + a² - 2 - a)
b (a + 2) (a - 1)
check your answer:
b (a + 2) (a - 1)
b (a²- a + 2a - 2)
a²b - ab + 2ab - 2b
2ab + a²b -2b - ab

9x + 11 = 110
what is x ?
Answers
Answer:
x = 11, lucky you, this stuff is easy
Step-by-step explanation:
110 - 11 = 99
9 x 11 = 99
99 + 11 = 110
Answer:
x = 11
Step-by-step explanation:
9x + 11 = 110
- Pass the 11 to the other side of the equation (grouping similar terms) and then perform the following operation:
9x = 110 - 11
9x = 99
- Now we have to obtain x by dividing 9 on both sides of the equation:
(9/9)x = 99/9
x = 99/9, which is divisible by 11.
In the bakery 4 cupcakes in one box. If 6 cups
were placed in the box, there would be 20 boxes left
empty. If 3 cupcakes were placed in each box, it
would run out of 20 boxes. Calculate how many
cupcakes were
in the bakery.
Answers
Answer:
There were 240 cupcakes in the bakery
Step-by-step explanation:
Assume that the number of boxes used is x
∵ If 6 cups were placed in the box, there would be 20 boxes left
∴ The number of cups in each box = 6
∴ The number of boxes used = (x - 20)
→ Multiply the number of cups in each box by the number of boxes
used to find the total number of cups
∵ The number of cups = 6(x - 20)
∴ The number of cups = 6x - 120 ⇒ (1)
∵ If 3 cupcakes were placed in each box, it would run out of 20 boxes
∴ The number of cups in each box = 3
∴ The number of boxes used = (x + 20)
→ Multiply the number of cups in each box by the number of boxes
used to find the total number of cups
∵ The number of cups3(x + 20)
∴ The number of cups = 3x + 60 ⇒ (2)
∵ The number of cups is the same in the two cases
→ Equate the right sides of (1) and (2)
∴ 6x - 120 = 3x + 60
→ Add 120 to both sides
∴ 6x = 3x + 180
→ Subtract 3x from both sides
∴ 3x = 180
→ Divide both sides by 3 to find x
∴ x = 60
∴ The number of boxes used is 60
∵ In the bakery 4 cupcakes in one box
∵ The number of boxes is 60
∴ The number of cupcakes = 4 × 60
∴ The number of cupcakes = 240
∴ There were 240 cupcakes

Statistics Probability
A survey of a freshmen English class asked students whether or not they ate breakfast the morning of the survey. The results are included in the table to the right.
(a) What is the probability that a randomly selected student ate breakfast?
(b) Of all students, what is the probability that a randomly selected student is female and ate breakfast?
(c) What is the probability a randomly selected student is male, given that the student ate breakfast?
(d) What is the probability that a randomly selected student ate breakfast, given that the student is male?
(e) What is probability of "is male" or "did not eat breakfast"?
(f) What is the probability of "is male and did not eat breakfast?
Answers
Answer:
Explained below.
Step-by-step explanation:
Denote the variable as follows:
M = male student
F = female student
Y = ate breakfast
N = did not ate breakfast
(a)
Compute the probability that a randomly selected student ate breakfast as follows:
[tex]P(Y)=\frac{n(Y)}{N}\\\\=\frac{198}{330}\\\\=0.60[/tex]
(b)
Compute the probability that a randomly selected student is female and ate breakfast as follows:
[tex]P(F\cap Y)=\frac{n(F\cap Y)}{N}\\\\=\frac{121}{330}\\\\=0.367[/tex]
(c)
Compute the probability a randomly selected student is male, given that the student ate breakfast as follows:
[tex]P(M|Y)=\frac{n(M\cap Y)}{n(Y)}\\\\=\frac{77}{198}\\\\=0.389[/tex]
(d)
Compute the probability that a randomly selected student ate breakfast, given that the student is male as follows:
[tex]P(Y|M)=\frac{n(Y\cap M)}{n(M)}\\\\=\frac{77}{154}\\\\=0.50[/tex]
(e)
Compute probability of the student selected "is male" or "did not eat breakfast" as follows:
[tex]P(M\cup N)=P(M)+P(N)-P(M\cap N)\\\\=\frac{n(M)}{N}+\frac{n(N)}{N}-\frac{n(M\cap N)}{N}\\\\=\frac{n(M)-n(N)-n(M\cap N)}{N}\\\\=\frac{154+132-77}{330}\\\\=0.633[/tex]
(f)
Compute the probability of "is male and did not eat breakfast as follows:
[tex]P(M\cap N)=\frac{n(M\cap N)}{N}\\\\=\frac{77}{330}\\\\=0.233[/tex]

the length of a rectangle is 5 less than twice the width. If the perimeter of the rectangle is 146 centimeters, find the dimensions of the rectangle
Answers
Answer:
26x47
Step-by-step explanation:
To calculate the length of the rectangle we would do 2(2x - 5) + 2(x) = 146
We simplify and get 6x - 10 = 146,
then divide both side by 6 and plus 10 both sides,
we will get
x = 26
Now we've found one of the length,
to find the other side we do 26 * 2 = 52, and subtract 52 from 146,
which would get 94, then we divide it by 2
94/2 = 47
The dimensions is 26x47

The soccer team boughtt-shirts at cost for $7.50. They want to sellthem as a fundraiser for between $11.00 and $15.00. What percent increase could they charge?
Answers
Answer:
47% or 100%Step-by-step explanation:
Step one:
given data
cost of T-shirt = $7.50
they could sell for either $11.00 and $15.00.
Required
The percent increase in the price
% increase = (cost-sales)price/cost price
% increase = (7.5-11)/7.5*100
% increase = 3.5/7.5*100
% increase = 0.47*100
% increase =47%
OR
% increase = (7.5-15)/7.5*100
% increase = 7.5/7.5*100
% increase = 7.5/7.5*100
% increase =1*100
% increase =100%
The increase could be 47% or 100%
