Step-by-step explanation:

1/10 km long, split into 4 equal parts.

so each part is 1/10 / 4 km long.

1/10 / 4 = 1/10 / 4/1 = 1×1 / (4×10) = 1/40

each athlete has to run 1/40 km.

bixtya [17]
If you pay $400 down, plus $80 for the next 12 months, that means you're paying (80*12)+400 which is equal to $1360. You're saving $100 by paying the entire total up front.

A medicine is decaying at a rate of 5% per hour. If there were initially 1000mg of the medicine, how much is left after 4 hours?
Stolb23 [73]

Answer:

  814.5 mg remain after 4 hours

Step-by-step explanation:

The multiplier of the original quantity is 1 -5% = 0.95 for each passing hour. The amount remaining after x hours is ...

  y = 1000·0.95^x

For x=4, the amount remaining is ...

  y = 1000·0.95^4 = 1000·0.81450625

  y ≈ 814.5 . . . mg remain after 4 hours

Help pls!!!how to solve it​
Mariana [72]

Answer:

q = 5/6

Step-by-step explanation:

First, we distribute.

16q - 10 = 4q

Then, we combine like terms.

-10 = 4q - 16q

-10 = -12q

Finally, we divide -12 on both sides.

5/6 = q, or q = 5/6

Hope this helps ^^
