Find the measure of each interior and exterior angle. The diagram is not to scale.
Answer/Step-by-step explanation:
✅m<1 = 90° (right angle)
✅m<2 = 90° (<1 and <2 are supplementary, and also linear pair)
✅m<3 = 90° (<1 and <3 are supplementary, and also linear pair)
✅m<4 = 115° (vertical angles theorem)
✅m<5 + m<4 = 180° (linear pair)
m<5 + 115° = 180° (substitution)
Subtract 115 from each side
m<5 = 180 - 115
m<5 = 65°
✅m<6 = m<5 (vertical angles are congruent)
m<6 = 65° (substitution)
✅m<7 = m<1 + m<6 (exterior angle theorem)
m<7 = 90° + 65° (substitution)
m<7 = 155°
✅m<8 = 180 - m<7 (linear pair theorem)
m<8 = 180 - 155 (substitution)
m<8 = 25°
✅m<9 = m<7 (vertical angles are congruent)
m<9 = 155° (substitution)
What is the value of y in the equation 9 + y = 8? this is extremely time sensitive
You have to switch the 8 to the left and the y to the right which would change the equation to 9-8=y
y=1
Answer: y =-1
Step-by-step explanation:y =-1
Last option is correct.
Step-by-step explanation:
The given equation is
In order to solve for y, we need to isolate y.
In this equation 9 is added with y and hence in order to eliminate 9 from the left hand side, we do reverse operation of addition.
The reverse operation of addition is subtraction. Hence, we subtract 9 to both sides of the equation
Using the order of operations, what should be done first to evaluate (-4) +6-(-3-4) (2) - 5?

You purchased concentrated cleaner that must be diluted before use. Container a is the cleaner, which is 20% solution. Container b is pure water. You are mixing together the contents of container a and container b to produce 40 gallons of 9% solution. How many gallons from each container are needed to create the 40 gallons of 9% cleaning solution?
Answer:
18 gallons from container [tex]a[/tex] and 22 gallons from the container [tex]b[/tex] to be mixed to get the required mixture.
Step-by-step explanation:
Given that the container [tex]a[/tex] has 20% concentrated cleaner
and container [tex]b[/tex] has pure water which has 0% cleaner.
Let x gallons from container a and y gallons from the container b are mixed to get a 9% concentrated solution.
So,
[tex]9\%\; \text{of}\; (x+y) = (20\% \; \text{of}\; x )+(0\% \; \text{of}\; y)\cdots(i)[/tex]
As the total amount of the final solution= 40 gallons
So, [tex]x+y=40\cdots(ii)[/tex]
Using the value of equation (ii) in equation (i), we have
9% of 40 = 20% of x
[tex]\Rightarrow 0.09\times 40=0.2 \times x[/tex]
[tex]\Rightarrow x=\frac{0.09\times 40}{0.2}[/tex]
[tex]\Rightarrow x=18[/tex] gallons.
From equation (ii),
18+y=40
[tex]\Rightarrow y=40-18=22[/tex] gallons.
Hence, 18 gallons from container [tex]a[/tex] and 22 gallons from the container [tex]b[/tex] to be mixed to get the required mixture.

I need to rearrange the variables to solve for pressure, P, as a function of volume and temperature, V and T. Write out your work on paper and submit a picture.
Answer:
P = (8T) / V
Step-by-step explanation:
P*V=8*T*P/P multiply both sides by P
P*V=8*T because P/P=1
P = 8T/V divide both sides by V

Step-by-step explanation:
5. You are buying orange juice for $3.50 per container and have a gift card worth $5. The function f(x) = 3.50x-5 represents your total cost f(x) if you buy x containers of orange juice and use the gift card. How much would you pay for 4 containers of orange juice?
Answer:
$9
Step-by-step explanation:
If you do 3.5*4 then you get 14. You then use the $5 gift card so you subtract 5 from 14 and get 9
using the equation, that would be f(x) = (3.5*4)-5. Using PEMDAS, you would do the parenthesis first so it would be f(x) = 14-5 which equals 9

Step-by-step explanation:
Terri is starting a babysitting service to make some extra money. She plans to charge a base fee of $10 plus $7 per hour. Write a function that could be used to represent her total charge for the babysitting service, y, as a function of the number of hours she babysits, x. *
y = 10x – 7
y = 7x – 10
y = 10x + 7
y = 7x + 10
Work Shown:
x = number of hours she babysits
1 hour = 7 dollars
x hours = 7x dollars (multiply both sides by x)
She earns 7x dollars after babysitting x hours if we ignore the $10 base fee. Add on the $10 base fee to get 7x+10 dollars total.
Therefore y = 7x+10 is the equation we want.
Answer:
I thought it would be y=10x+7 because the base fee which is the starting fee is 10 and your adding 7 every hour so that would be +7.

Solve for x by factoring
X^2+4x-21=0
There are multiple answers
Answer:
[tex]x=3,-7[/tex]
Step-by-step explanation:
We can solve for x by using [tex]\frac{-b\pm\sqrt{b^{2} -4ac} }{2a}[/tex]
By applying this on the quadratic equation, we get:
[tex]x=\frac{-4\pm\sqrt{4^{2}+84} }{2}[/tex]
Which simplifies to:
[tex]x=\frac{-4\pm10}{2}[/tex]
[tex]\therefore x=3,-7[/tex]

Ina certain county weights of women are normally distributed with a mean of 138 lb and a standard deviation of 15 lb. What percentage of women in that country weigh more than 120 lb
Answer:
88.493%
Step-by-step explanation:
We solve this question using z score formula.
Z score = x - μ/σ
where
x is the raw score = 120lb
μ is the population mean = 138lb
σ is the population standard deviation = 15lb
Hence,
z = 120 - 138/15
= -1.2
Probability value from Z-Table:
P(x<120) = 0.11507
P(x>120) = 1 - P(x<120)
1 - 0.11507
= 0.88493
Converting to percentage
= 0.88493 × 100
= 88.493%
The percentage of women in that country weigh more than 120 lb is 88.493%
What is the answer to this equation
1) 4(x + 5) = 40
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]4(x + 5) = 40[/tex]
Divide sides by 4
[tex] \frac{4}{4} \times (x + 5) = \frac{40}{4} \\ [/tex]
[tex]x + 5 = 10[/tex]
Subtract sides 5
[tex]x + 5 - 5 = 10 - 5[/tex]
[tex]x = 5[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
CHECK :
[tex]4(5 + 5) = 40[/tex]
[tex]4 \times 10 = 40[/tex]
[tex]40 = 40[/tex]
Thus the solution is correct.

Gribbles are small, pale white, marine worms that bore through wood. While sometimes considered a pest since they can wreck wooden docks and piers, they are now being studied to determine whether the enzyme they secrete will allow us to turn inedible wood and plant waste into biofuel.1 A sample of 50 gribbles finds an average length of 3.1 mm with a standard deviation of 0.72. Give a best estimate for the length of gribbles, a margin of error for this estimate (with 99% confidence), and a 99% confidence interval. Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places. point estimate = Enter your answer; point estimate margin of error = Enter your answer; margin of error The 99% confidence interval is Enter your answer; The 99%confidence interval, value 1 to Enter your answer; The 99%confidence interval, value 2
Answer:
a) The Margin of Error = 0.26
b) The 99% Confidence Interval = ( 2.84, 3.36)
Step-by-step explanation:
a) Margin of Error
The formula for Margin of Error =
z × Standard deviation/√n
From the above question
The z score for 99% confidence interval = 2.576
Standard deviation = 0.72
n = Random number of samples = 50
Margin of Error =
2.576 × 0.72/√50
= 1.85472 /√(50)
= 0.2622970178
Approximately to 2 decimal places = 0.26
b) 99% Confidence Interval
= Mean ± Margin of Error
Mean = 3.1mm
Confidence Interval = 3.1 ± 0.26
3.1 ± 0.26
= 2.84
3.1 + 0.26
= 3.36
The 99% Confidence Interval = ( 2.84, 3.36)
