Answer:

the red answer

Step-by-step explanation:

Answer:

red

Step-by-step explanation:

Adjacent angles are angles that share a common vertex without overlapping

( to be more specific they are angles that are right next to each other )

∠BOD and ∠AOC are not next to each other, they are vertical angles therefore dark blue is not the answer

∠COB and ∠DOA are not next to each other but vertically aligned with each other ( vertical angles ) therefore cyan is not the answer

∠COB and ∠AOD are the same as ∠COB and ∠DOA therefore yellow is not the answer

∠AOD and ∠AOC are right next together and share a common vertex without overlapping each other therefore red is the correct answer

Answer:

D. Subtract the sum of the three test scores from the product of 75 and 5, and divide the result by 2

Step-by-step explanation:

Alright imma try and make this as simple as possible.

My steps:

1) follow the answers steps:

(100 + 85 + 70) - (75 • 5) = -120

-120 divided by 2 = -60

Now, yes the answer is negative but check this out!

3) add 60 twice to 100, 85, and 70: ( 100 + 85 + 70 + 60 + 60) = 375

4) then divide 375 by 5: 375 divided by 5 = 75

Which is our mean! And there you have it! I really hoped this helped and your not confused. Good luck! :)

Step-by-step explanation:

At time t=​0, water begins to drip out of a pipe into an empty bucket. After 48 ​minutes, there are 6 inches of water in the bucket. Write a linear function rule to model how many inches of water w are in the bucket after any number of minutes t.
The linear function rule is w
plzzzz help

Answers

Answer:

w = 0.125t

Step-by-step explanation:

y = mx + b

make it so that it relates to the problem:

w = mt + b

w = inches of water left after t minutes of time

t = time

m = rate in which the water is dripping

b = water level (when b = 0, the bucket is empty)

Plug the given information into the formula:

6 = 48m + 0

Get the variable, m, by itself on the other side of the equal sign.

*Remember that what you do on one side, must done on the other.

    6 - 0 = 48m + 0 - 0

    6 / 48 = 48m / 48       ← Divide by 48 on both sides to isolate the variable.

    8 = m                           ← This means that 1 in of water drips after 8 mins.

    1 / 8 = 0.125                ← This means that 0.125 in of water drips each min.

So...

0.125 inch/minute, meaning that w = 0.125t

W=0.125 t
