If angleA and angleB are supplementary angles, and angleA = 63°, find the measure of angleB. A. B = 27° B. B = 63° C. B = 117° D. B = 153°

Answers

C. B = 117° because 63°+117°=180°

Answer: C. B=117°.

Step-by-step explanation:

We know that if a pair of angle are supplementary then their sum is added up to 180 degrees.

Given : angle A and angle B are supplementary angles.

i.e [tex]\angle{A}+\angle{B}=180^{\circ}[/tex]

Also, angle A = 63°

i.e [tex]63^{\circ}+\angle{B}=180^{\circ}[/tex]

i.e [tex]\angle{B}=180^{\circ}-63^{\circ}[/tex]

i.e [tex]\angl{B}=117^{\circ}[/tex]

Hence, the measure of angleB is 117°.

Marco has room for 15 more minutes of songs on his mp3 player. he has 3 songs to upload with the following lengths: 5.15 minutes,3.8 minutes, and 4.4 minutes. After uploading all three songs, about how many minutes will he have left?

Answers

He has room for 15 more minutes.
He uploaded 3 songs with the times 5.15, 3.8, and 4.4.
5.15 + 3.8 + 4.4 = 13.35

He now added 13.35 more minutes onto his mp3 player.
To find the room in minutes he has left, subtract that number from 15.
15 - 13.35 = 1.65

He has 1.65 minutes left.

There are two jars. One jar contains 2 red gum balls , 3 green gum balls ,and 1 yellow gumball.the other jar contains 2 blue balloons and 3 purple balloons . Jeff randomly draws one gumball and then balloon .what is the probability that he will draw a green gumball and a blue balloon?
A.1/15
B.2/15
C.1/5
D.3/10

Answers

There are 3 green gumballs out of 6 in total. So, the odds of Jeff pulling out a green gum ball is 3/6, or 1/2.

There are 2 blue balloons out of 5 in total. So, the odds of Jeff pulling out a blue balloon is 2/5.

Therefore, the combined odds of Jeff pulling out a green gum and a blue balloon is 1/2 multiplied by 2/5, which is 2/10, or 1/5, Making the answer C.

The quantity demanded of a certain brand of DVD player is 3000/wk when the unit price is $485. For each decrease in unit price of $40 below $485, the quantity demanded increases by 500 units. The suppliers will not market any DVD players if the unit price is $334 or lower. But at a unit price of $559, they are willing to make available 2500 units in the market. The supply equation is also known to be linear.

Answers

Given that the quantity demanded of a certain brand of DVD player is 3000/wk when the unit price is $485. For each decrease in unit price of $40 below $485, the quantity demanded increases by 500 units. The suppliers will not market any DVD players if the unit price is $334 or lower. But at a unit price of $559, they are willing to make available 2500 units in the market. The supply equation is also known to be linear.

Part (a): Find the demand equation.
To find the demand equation, we notice that the demand function is linear because we were told that for each decrease in unit price of $40 below $485, the quantity demanded increases by 500 units.

Given that at a price of $485, the quantity demanded is 3,000 and given that for each decrease in unit price of $40 below $485, the quantity demanded increases by 500 units. Then for a price of $485 - $40 = $445, the quantity demanded is 3,000 + 500 = 3,500 units

Thus, using the formula for the equation of a straight line and the points (3,000, 485) and (3,500, 445), we find the demand equation as follows:

[tex] \frac{p-485}{q-3,000} = \frac{445-485}{3,500-3,000} \\ \\ \Rightarrow \frac{p-485}{q-3,000}= \frac{-40}{500} =- \frac{2}{25} \\ \\ \Rightarrow25(p-485)=-2(q-3,000) \\ \\ \Rightarrow25p-12,125=-2q+6,000 \\ \\ \Rightarrow25p+2q=18,125[/tex]

Part (b): Find the supply equation.
To find the supply equation, given that the supply function is linear and that the suppliers will not market any DVD players if the unit price is $334 or lower. But at a unit price of $559, they are willing to make available 2500 units in the market.

Thus, using the formula for the equation of a straight line and the points (0, 334) and (2,500, 559), we find the demand equation as follows:

[tex] \frac{p-334}{q-0} = \frac{559-334}{2,500-0} \\ \\ \Rightarrow \frac{p-334}{q}= \frac{225}{2,500} =\frac{9}{100} \\ \\ \Rightarrow100(p-334)=9q \\ \\ \Rightarrow100p-33,400=9q \\ \\ \Rightarrow100p-9q=33,400[/tex]

(c) Find the equilibrium quantity and price.
The equilibruim quantity and price is given by the quantity and price at which the quantity demanded is equal to the quantity supplied. It is obtained by equating the demand and the supply equations.

i.e.
From demand equation, we have
[tex]25p+2q=18,125 \\ \\ \Rightarrow25p=-2q+18,125 \\ \\ \Rightarrow p= -\frac{2}{25}q +725 \ . \ . \ . (1)[/tex]

From supply equation, we have
[tex]100p-9q=33,400 \\ \\ \Rightarrow100p=9q+33,400 \\ \\ \Rightarrow p= \frac{9}{100} q+334 \ . \ . \ . (2)[/tex]

Equating equations (1) and (2), we have
[tex]-\frac{2}{25}q +725=\frac{9}{100} q+334 \\ \\ \Rightarrow\frac{9}{100} q+\frac{2}{25}q=725-334 \\ \\ \Rightarrow \frac{17}{100} q=391 \\ \\ \Rightarrow q= \frac{391\times100}{17} =2,300[/tex]

Substituting for q into equation (1), we have
[tex]-\frac{2}{25}(2,300) +725=-184+725=541[/tex]

Therefore, the equilibruim quantity is 2,300 units at a price of $541.

How did I get a=60 as an answered?

Answers

The square marker means that the angle is a right angle, or a 90 degree angle.

Rule: For any triangle, the three angles add to 180 degrees.

The angles are: 'a', 'a-30', and 90 degrees

Add them up and set the result equal to 180. Then solve for 'a'
( a ) + ( a - 30 ) + 90 = 180
(a + a) + (-30 + 90) = 180
2a + 60 = 180
2a + 60 - 60 = 180 - 60 ..... subtract 60 from both sides
2a = 120
2a/2 = 120/2
a = 60

Side Note: Since a = 60, this makes a-30 = 60-30 = 30. So the two other angles of the triangle are 60 and 30. Add up the three angles to get 30+60+90 = 90+90 = 180 so that confirms we have the right answer.

Anton bought a picnic cooler. His total bill, with tax, was $7.95. He paid 6 percent sales tax. How much did he pay for the cooler alone without the tax?
For the cost of the cooler, solve:
106% of cost of cooler = $7.95

To find the total bill in terms of the cost of the cooler :
100% of cooler price
+ 6% of cooler price (tax)
--------------------------------------------
106% of cost (7.95)

Now, solve this problem.

106% of $ _______ = $7.95

Answers

106% of $ _______ = $7.95

this means that 1.06 of the price of the cooler is 7.95

so we can assume th
at the cooler price is x

then:

1.06 x = 7.95

Divide both sides by 1.06, we get:

x = 7.5

The price of the cooler itself without tax is $7.5

Matt needs to make $230 for a trip. He plans on selling 16 bags of snacks to raise money. The lowest acceptable price for him to sell these to make his goal is $______.

Answers

Divide 230 by 16 and you'll get 14 point a lot of numbers so then just keep adding some cents like $14.20 then multiply by 16 so 16 x $14.20 =227 so then do 16 x $14.40 =230 so your answer is $14.40 I believe

So here you just want to find how many times you can fit 16 into 230 to find the lowest acceptable price.

The actual answer is 14.375, but we should round up to 14.38.

So the lowest acceptable price for Matt to sell bags of snacks is $14.38.

If you broke it into the left section and the right bottom section youd get 2 rectangles and the area of a rectangle is defined as A=Length*Width. The left would be a 3*4 rectangle making its area 12 units^2 and the right would have a height of (3-2) units and a length of (7-4) units making its area 1*3 or just 3 units^2, if you add both areas you get the total area, which is 15 units^2

break it up into chunks: the small rectangle and the big rectangle.
subtract 7 and 4 to get the big side of the rectangle, and subtract 3 and 2 to get the small side. then find the area of the big rectangle and small rectangle to get the area of the entire rectangle. area equals 15 units^2

what is the missing reason in the proof

Answers

There's a lot going on, but the main thing to focus on really is the equation
AE+EB = CF+FD

and on the equation
EB = CF

Because the second equation (shown above) is true, we can effectively replace the "EB" with "CF" like so
AE+EB = CF+FD
AE+CF = CF+FD

Then we can subtract CF from both sides
AE+CF = CF+FD
AE+CF-CF = CF+FD-CF
AE = FD

When I subtracted CF from both sides, I used the Subtraction Property of Equality, which is the answer needed to go into the blank.

Of a group of 500 people, 60 are fit enough to climb Mount Shasta in California. The group has 300 women and 200 men. 12% of the men are fit to climb the mountain. What is the probability that a person picked at random from the group is a male or is fit to climb Mount Shasta?

Answers

Since 12%=0.12 by moving the decimal over 2 spots to the left, we multiply 200 by 0.12 to get 24. The amount of women fit to climb the mountain (since there are only women and men in this example) is 60-24=36. That means that there are 200+36=236 people that are either male, fit to climb the mountain, or both. 236/500=0.472=47.2%. If it means that you can't be a male and fit to climb, it's 200-24+36=212. 212/500=0.424=42.4%. This is due to that we subtract the 24 males who are both and add the 36 females that are fit
