Answer:

16. D. 180 inches

17. A. 1/20 pound

18. D. (2,6)

19. A. 2/8

20. D. 22

Step-by-step explanation:

16. every 5 feet is 60 inches there is 15 feet because 1 yard=3 feet so 60*3=180

17. when you round it upwards you would have 30/40 and 32/40 so it would be 2/40 and then simply 1/20 so therefore it would be 1/20

18. The cost of milk is 3 so that would be (3,y) then every gallon would be y so (3,1)

19. You know this because when you plug in all the other numbers none of the rest of them work but A so therefore it must be A

20. So first you would multiply 2*2*2*2=8 Then you would divide 172/8=22. So therefore your answer would be 22

5 days 6 hours 20 minutes minus 3 days 8 hours 40 minutes plz help will make brainliest
Blababa [14]

Answer:

1 day   21 hours   40 minutes

Step-by-step explanation:

5 days 6 hours 20 minutes

- 3 days 8 hours 40 minutes

============================

We will need to borrow  minutes from the hours because we don't have enough.

1 hour = 60 minutes

6-1 = 5 hours

20 +60 = 80 minutes


5 days 5 hours 80 minutes

- 3 days 8 hours 40 minutes

==========================

We will need to borrow  hours from the days because we don't have enough.

1 day = 24 hours

5 -1 =4 days

5 + 24 = 29 hours


4 days 29 hours 80 minutes

- 3 days 8 hours 40 minutes

==========================

1 day   21 hours   40 minutes

Please help me with this...
AURORKA [14]

Answer:

- 84 + 10i

Step-by-step explanation:

A complex number in standard form is a ± bi

a is the real part and bi the imaginary part

and \sqrt{-1} = i

Given

\sqrt{-100} - 84

= \sqrt{100(-1)} - 84

= \sqrt{100} × \sqrt{-1} - 84

= 10i - 84

= - 84 + 10i ← in standard form

You unfold chicken wire to make a circular pen. The area of the pen is 78.5 square meters. How many meters of chicken wire do yo
Lelu [443]
Circular pen means you are going to use Area = Pi(r^2). 

So 78.5 = pi(r^2). Divide by pi on both sides to get r^2 = 78.5/pi. Take the square root of that to get r or radius = approximately 4.99. If you need an exact answer then use \sqrt{ \frac{78.5}{ \pi } } for the next part because you are not done yet.

Plug whatever R you use into the circumference formula of Circumference = 2(pi)(r).

If you use 4.99, you do 2(pi)(4.99) which is approximately 31.35. If you use the exact answer, you do 2(pi)(\sqrt{ \frac{78.5}{ \pi} }) which gives you approximately 31.41. 

Either way you'll need about 31 meters of chicken wire but the 31.40796 or ~31.41 is closer to the exact answer.
