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
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 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.

Answers
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.
Describe how the graph of each function compares with the graph of the parent function y=log5 x+1

B: It translates the graph to the left 1 unit.
C: It translates the graph up 1 unit
D: There is no change in the graph.
Answers
C- it translates the graph up 1 unit.
Answer:
C
Step-by-step explanation:
[tex]y=log_5(x)+1[/tex]
Here parent function is [tex]y=log_5(x)[/tex]
If any number is added or subtracted at the end of parent function then we we move up or down
when we compare [tex]y=log_5(x)+1[/tex] with parent function , +1 is added at the end.
So the graph will be translated 1 unit up
Answer : C: It translates the graph up 1 unit

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
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 $7.5
----.----.----
to check you answer:
7.5 + 7.5*6%= 7.5 + 7.5*0.06 = 7.5 + 0.45 = 7.95$

When Lou started his current job, his employer told him that he would receive two vocation days for each full year he worked. How long will it take him to earn 18 paid vacation days?
Answers
By solving a linear equation, we will see that he needs to work for 9 years.
How long will take Lou to earn 18 vacation days?We know that for each year that he works, he gets 2 vacation days.
So we can write the linear equation:
y = 2*x
Where y is the number of vacation days, and x is the number of years that he worked.
We want to find the value of x such that y = 18, then we need to solve:
18 = 2*x
Solving for x w get:
18/2 = x = 9
This means that to get 18 vacation days, he needs to work for 9 years.

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
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
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.

Answer:
y > x² - 6
y < x² + 2 Option A
Step-by-step explanation:
Given that,
Two parabolic inequality's graph is given.
If we graph inequality y > x² - 6
it shaded the upper part of graph because greater than sign is given.
If we graph inequality y < x² + 2
it shaded the lower part of graph because less than sign is given.
So, common shaded part is mid of both the graph.
Final answer is:
y > x² - 6
y < x² + 2
That's the final answer.

In the world problem, we learn Eduardo's dad is purchasing 1 adult ticket and 2 child tickets. This gives us: X= 17(1) + 13(2)

Answers
First, add 2 to both sides. It would then be 5x = 3x + 10. Then subtract 3x from both sides and you would end up with 2x = 10. Divide 2x by 2 and the 10 by 2. The answer is x = 5.
2x-2=8
Add 2 to both sides
2x=10
Divide both sides by 2
x=5
Final answer: x=5
