use what you already know to find a,b and c. input each value NEED HELP

Answers

Answer:

b=100

a=80

c=100

Step-by-step explanation:

to find b we know that in a straight angle there is 180 degrees and since we already know that one side is 80 degrees we just need to substract 180 by 80 to get 100 degrees.

since its parallel lines we can confirm that 80degrees and r are coresponding angles so r=80.Which also means a and r are alternate angles so a=80.

Lastly to find c we need to do the same thing as we did with b. Which means c=100    

Find they -intercept and -x intercept of the line. -9x-2y=-14

Answers

Answer:

the x-intercept is when y equals 0, so it's 14/9, which is 1 5/9

the y-intercept is when x equals 0, so it's 7

Step-by-step explanation:

Answer:

Step-by-step explanation:

y -intercept, put x = 0:

-9(0) - 2y = -14

2y = 14

y = 7.

So y-intercept is at (0, 7).

x -intercept, put y = 0:

-9x - 2(0) = -14

-9x = -14

x = 14/9/

So x-intercept is at (14/9, 0).

A car is traveling with a velocity of 65.0 km/h. In the next 15 minutes the car gradually slows down at the end of the 15 minutes the car is traveling at 45.0 km/h what is the average acceleration of the car during the time it slows down?

Answers

Answer:

- 0.006173 m/s²

Step-by-step explanation:

Given :

Initial Velocity, u = 65km/hr = (65*1000) / 3600 = 18.056 m/s

Final velocity, v = 45 km/ hr = (45*1000) / 3600 = 12.5 m/s

Time at which change in velocity occurred = 15 minutes = 15 * 60 = 900 s

Acceleration = Change in velocity with time

Acceleration = (v - u) / t

Acceleration = (12.5 - 18.056) / 900

Acceleration (deceleration) = - 5.556 / 900

Deceleration = - 0.006173 m/s²

What is the solution(s) to the equation 5a2 - 44 = 81?
A
+25
B
-5
55
D
1125

Answers

Answer:

B

Step-by-step explanation:

5a^2 - 44 = 81                     Add 44 to both sides

5a^2 = 81 + 44                    Collect like terms

5a^2 = 125                          Divide both sides by 5

a^2 = 125/5                  

a^2 = 25                              Take the square root of both sides

√a^2 = √25

a = +5

a = -5

Joseph has saved $325. He wants to purchase a surfboard that costs $785. If he saves $12 each week from the money he earns mowing yards and another $6 each week from his allowance, how many weeks will it take Joseph to save enough to buy the surfboard?

Answers

Answer: 25.6 weeks

Step-by-step explanation:

He has saved $325 already so the amount left to purchase the surfboard is:

= 785 - 325

= $460

He saves $12 and $6 every week.

= $18.

Number of weeks left:

= 460/18

= 25.6 weeks

Warren drank 4 5 liter of water Monday before going jogging. He drank 2 3 liter of water after his jog. How much water did Warren drink altogether? Write your answer as a mixed number.

Answers

Answer: Warren drank 1 7/15 Liters of water  altogether

Step-by-step explanation:

Step 1

Amount of water drank before jogging = 4/5 liters

Amount of water drank after jogging =2/3 liters

Amount of water drank altogether =Amount of water drank before jogging +Amount of water drank after jogging

Step 2

Amount of water drank altogether = 4/5 + 2/3

The LCM of 5 and 3 gives 15 , so we have the  denominator becoming 15,

4/5 + 2/3 =     /  15

15 divided by 5 gives 3 multiplied by 4  gives us 12 and also 15 divided by 3 gives 5 multiplied by 2 gives 10 , such that we have

12 + 10  / 15

= 22/ 15

=1 7/15
