Answer:

Step-by-step explanation:

We know that a straight angle is equal to 180°. Therefore, 120°+(a)=180°

We can solve for (a) by subtracting 120 from 180, which is 60.

180-120=60

m∠a+120°=180°

m∠a=60°

We know that the sum of all angles in a triangle is 180°.

Therefore, (a)+60°+(b)=180°

We know that (a) is equal to 60°, so our new equation is:

60°+60°+b=180°

60+60=120

180-120=60

m∠b+60°+60°=180°

m∠b=60°

Answer:

Function 1: None of the Above

Function 2: Quadratic

Function 3: Linear

Step-by-step explanation:

Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.

Function 2: It has a vertex-(6,32)

Function 3: The y-axis goes up at a constant rate of 6.

Answer:

5625 feet

I hope it's helps you

Answer:

5625 feets

Step-by-step explanation:

Rate(feet/seconds) = height(feets)/time(seconds)

175 = x/25

x = 4375

After the skydiver opens his parachute the height reduces

Initial height – reduced height

10000 – 4375

= 5625 feets

Answer:

area =12

Step-by-step explanation: you don't need to use all 4 numbers just used the base which is 8 then times it with 3 which gives you 24 then divided it by 2 which gives you 12.

Answer:

Area=12

Step-by-step explanation:

You take the height which is 3 and multiply it by the base which is 8. Then you get 24 and divide it by 2 which gives you 12.

Answer:

The probability is not 4/12 for the red marble, but 4/11

Step-by-step explanation:

Francisco calculated to probability of drawing a yellow marble correctly, but since he isn't replacing it, the amount of marbles in the bag is not 12, but 11. Since there are 4 red marbles, the probability is 4/11

Answer:

0.75

Step-by-step explanation:

Add sixteen on both sides

9 = 12x

Divide by 12

x = .75

Using it's concept, it is found that the probability of spinning an odd number, not flipping heads, then not spinning a 6 is:

[tex]p = \frac{20}{81} = 24.69\%[/tex]

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

Then, the probability of the compound event is:

[tex]p = \frac{5}{9} \times \frac{1}{2} \times \frac{8}{9} = \frac{20}{81} = 24.69\%[/tex]

Answer:

She will earn 150$

Step-by-step explanation:

4% = 0.04

0.04 x $625 = 25

Now we divide 25 by the number of years, which is 6.

6 x 25 = 150$

Therefore, Skye earns 150$ from interest over the course of 6 years.

Answer: A is yes. B is no, C is yes

Step-by-step explanation: The reason A is yes, is because the terms are 27b, 12b and 4 because they are separated. The reason B is no, is because the like terms are 27b and 12b because their variables are alike. The reason C is yes, is because 27b+12b=39b+4 is an équation simplified.

Answer:

You can find X in an equation by doing the opposite operation from both sides.  For example, let"s do 5x=25.  Since there is multiplication, we can use division to isolate the variable.  You would divide both sides by the coifeiccent to get x=5.

Answer:

1: Tip, $2.23

2: Tax, $0.74

3: Total, $17.87

4: Split, $5.95

Step-by-step explanation:

To find the tip, you must multiply the tip percentage by the bill, (which has not been taxed yet). The tip is 15%, which is equivalent to 0.15. The tip multiplied by the bill (0.15×14.90) equals $2.23.

To find the tax, you do the same as you did with the tip. The tax is 5%, which equals 0.05. The tax multiplied by the bill, (0.05×14.90) equals $0.74. The total cost is the bill, tip, and tax added together, (14.90+2.23+0.74) equals $17.87. To find out how much each person will pay equally, you must divide the total bill by the amount of people, (17.87÷3) which equals $5.95.

Answer:

3x−3

Step-by-step explanation:

2x+x−3

=2x+x+−3

Combine Like Terms:

=2x+x+−3

=(2x+x)+(−3)

=3x+−3

Answer:

B

Step-by-step explanation:

I am not sure what your teacher wants but I guess you can say the following:

at n = 1, the cost is 4 dollars.

at n = 2, the cost is 8 dollars.

This trend is the same where the cost increases by 4 as n increases by 1. This means the C = 4n. We can check this by plugging values into the equation.

For the first row, C = 4, n = 1, and so the equation satisfies it. For the second row in the table, C = 8, n = 2, and so the equation works again. The other data points also agree using the equation.
