Answer:
No, but they add up to 180 degrees.
Step-by-step explanation:
Take one of the angles, interior or exterior and subtract it from 180 and you should have your other angle.

A recipe for making paste calls for a ratio of flour to water of 4:2. If you only have 2 cups of flour, how much water should you put in? Explain how you know.
Answer:
1 Cup of Water
Step-by-step explanation:
Well, this is pretty simple.
This questions topic is known as Equivalent Ratios.
To find an equivalent ratio, add or divide the numbers by the same amount.
Let's do it together.
4:2 is the ratio we already have. If we have to make it have 2 cups of flour, let's divide 2 on both sides.
Since 4 divided by 2 is 2, and 2 divided by 2 is 1,
We can confirm that you would need to put in 1 cup of water.

Find the exact value of 0 tan165 using the appropriate identity formula. Rationalize denominator if needed.
Answer:
[tex]tan165^0 = -2 + \sqrt{3}[/tex]
Step-by-step explanation:
Given;
tan165⁰
165⁰ is in the second quadrant, and sine is positive in this quadrant, thus tan will be negative.
In second quadrant, tanθ = -tan(180 - θ)
tan165⁰ = -tan(180-165)
tan165⁰ = -tan15⁰
[tex]- tan15^0 = -tan(60 - 45)\\\\ tan(\alpha - \beta) = \frac{tan \alpha -\ tan \beta}{1 + tan \alpha tan \beta}\\\\ -tan(60 - 45) = -(\frac{tan 60 - tan 45}{1+tan60tan45} )\\\\ -(\frac{tan 60 - tan 45}{1+tan60tan45} )= -(\frac{\sqrt{3} \ - 1}{1+ \ \sqrt{3} } ) = \frac{1 \ -\sqrt{3} }{1+ \ \sqrt{3} }\\\\\frac{1 \ -\sqrt{3} }{1+ \ \sqrt{3} } =( \frac{1 \ -\sqrt{3} }{1+ \ \sqrt{3} })(\frac{1 - \ \sqrt{3}}{1 - \ \sqrt{3}} ) = \frac{1-\sqrt{3} -\sqrt{3} \ +\ 3 }{1\ -\ 3} = \frac{4-2\sqrt{3} }{-2}[/tex]
[tex]\frac{4-2\sqrt{3} }{-2} = -2 + \sqrt{3}[/tex]
Therefore, [tex]tan165^0 = -2 + \sqrt{3}[/tex]

Amber and Will are in line together to buy tickets. Amber moves back by 3 places three times to talk to friends. She then is invited to move 5 places up in line. Will moved back by 4 places twice, and then moved up in line by 3 places. Overall, who moved farther back in line?
Answer:
Amber
Step-by-step explanation:
Lets pretend they both started at 10
Amber moved back 3 places 3 times, (1), then moved up 5 places (6)
Will moved back 4 spaces twice (2) then moved up 3 places (5)

∠CFD=60 (all the angles in an equilateral triangle are 60)
#6
∠AFD=150=∠AFB+∠BFC+∠CFD
∴150=∠AFB+35+60
∴∠AFB=55
#7
An isosceles triangle has one unique vertex angle and two equal base angles. All the angles in a triangle add up to 180. We know the base angles (55), so:
180 = ∠ABF + 2(55)
∴∠ABF = 70
#8
∠A=∠AFB = 55 (base angles of an isosceles triangle)
11. An isosceles triangle has one unique vertex angle and two equal base angles. All the angles in a triangle add up to 180. Vertex angle is 18, so the sum of both bases is 180-18=162. Therefore, each base angle is 81.

At summer camp, there are 3 boys for every 4 girls. If there are 63 boys & girls at camp, how many boys are there?
Answer:
turn it into an equation
since the total number of students is 63 and for every 3 boys are 4 girls
3x + 4x = 63
7x = 63
x = 63/7
x= 9
to get the number of boys
3 x 9 = 27
therefore the number of boys is 27

Using the binomial distribution, it is found that the probabilities are given as follows:
a) 0.2036 = 20.36%.
b) 0.0011 = 0.11%.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, the parameters are given as follows:
p = 0.95, n = 5.
Item a:
The probability is P(X = 4), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 4) = C_{5,4}.(0.95)^{4}.(0.05)^{1} = 0.2036[/tex]
Item b:
The probability is:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).
Then:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{5,0}.(0.95)^{0}.(0.05)^{5} \approx 0[/tex]
[tex]P(X = 1) = C_{5,1}.(0.95)^{1}.(0.05)^{4} \approx 0[/tex]
[tex]P(X = 2) = C_{5,2}.(0.95)^{2}.(0.05)^{3} = 0.0011[/tex]
Then:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0 + 0 + 0.0011 = 0.0011.

Which of the following is a cause of inflation?
consumers growing apathetic and failing to notice attempts to raise prices
b demand continually exceeding supply, leading to an imbalance of money and goods in the
market
C a natural consequence of the use of money instead of trade goods
d government intervention demanding that prices be raised
Answer:
D. government intervention demanding that prices be raised
Step-by-step explanation:
Inflation means when prices increase and fall in purchasing value of money. The only logical answer would be "Government intervention demanding that prices be raised. " Because it is the only one that talks about prices increasing.
The answer choice which is a cause of inflation is; Choice B; demand continually exceeding supply, leading to an imbalance of money and goods in the market.
What is then cause of Inflation?Inflation is simply a measure of the rate of rising prices of goods and services in an economy. More specifically, a surge in demand for products and services can cause inflation as consumers are willing to pay more for such product in less supply.

A cube has a volume of 216 cubic inches, and another cube has a volume of 729 cubic inches. What is the ratio of the surface area of the larger cube to the surface area of the smaller cube?
Answer:
Ratio is [tex]\frac{9}{6}[/tex]
You can simplify it of course to 3/2
Step-by-step explanation:
Volume of a cube is V = length^3 or l^3
Volume for larger cube = 729 cubic inches
Volume for smaller cube = 216 cubic inches
Surface area is S = 6*l^2
So we just need to find the length of each side of the cube.
We take the cube root for each cube volume since there are three sides.
Larger cube = 729^(1/3) = 9
smaller cube = 216^(1/3) = 6
Ratio is [tex]\frac{9}{6}[/tex]

In order to finance furniture for an office in a new retail store, Tools for Schools signs a 140-day simple discount note with a maturity value of $19300. Find the proceeds if the discount rate is 13.5%.
Answer:
I think it would be $ 66.23
I hope I can help you
have a nice day.
The proceeds of the simple discount note are approximately $18,296.16.
To find the proceeds of the simple discount note, we can use the formula:
Proceeds = Maturity Value - Discount
Where:
Maturity Value = $19,300 (given)
Discount = Maturity Value * Discount Rate * Time
The discount rate is 13.5%, which can be written as 0.135 in decimal form. The time is 140 days. Now, let's calculate the discount:
Discount = $19,300 * 0.135 * (140/360)
we divide by 360 because simple interest is typically based on a 360-day year.
Discount = $19,300 * 0.135 * 0.388888...
Discount ≈ $1,003.84 (rounded to two decimal places)
Now, let's find the proceeds:
Proceeds = $19,300 - $1,003.84
Proceeds ≈ $18,296.16 (rounded to two decimal places).
