Mathematics

Answer:

8.625 ft for each side.

Step-by-step explanation:

This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th  is 9 (although i doubt saying 1th is right, but just because).

A dose of medicine is made by diluting one part of concentrate to 5 parts of water. How much of the concentrate should there be
Anastasy [175]

Answer:

15 ml

Step-by-step explanation:

If we mix 1 part concentrate and 5 parts water, we have 6 parts in total.

To create 90ml medicine, <em>how many "6 parts" are there?</em>

There would be 90/6 = 15 total "6 parts".

Each of the "6 parts's" 1 part is concentrate, so concentrate would be 1 * 15 = 15 ml.

<u>In ratio:</u>

\frac{Concentrate}{Total(Water+Concentrate)}=\frac{1}{5+1}=\frac{1}{6}\\\frac{1}{6}*90=15

If a sprinkler waters 1/15 of a lawn in 1/5 of an hour, how much time will it take to water the entire lawn?
GaryK [48]

Answer:

3 hours

Step-by-step explanation:

To solve this we can first find out how many minutes is 1/5th of an hour which is: 12 mins.

Now we know it will take 15 sets of 12 minutes to water the full lawn so we can multiply 15*12 to get our answer.

15*12 = 180

Now we divide 180 (minutes) by 60 (minutes) to find out how many hours that is:

180/60 = 3 hours

Hope this helped! If possible please leave a thanks so I can continue to help out others :),

comment if you have any questions.
