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.

Answer:
The length of the side adjacent to that angle is 26 units
Step-by-step explanation:
We are given
In a right triangle, the side opposite a 33 degree angle is 17 units
Firstly, we will draw diagram
we can use trig
now, we can solve for x
So,
The length of the side adjacent to that angle is 26 units
Answer:
brainliest also gimmie a sec to figure it out
Step-by-step explanation:
We will represent everything in cents
nickles are worth 5 cents and dimes are 10 cents
n=number of nickles
d=number of dimes
60 total coins
n+d=60
total is 430 cents
5n+10d=430
divide both sides by 5
n+2d=86
we gots
n+d=60 and
n+2d=86
eliminate
multiply first equation by -1 and add to 2nd equation
-n-d=-60
<u>n+2d=86 +</u>
0n+1d=26
d=26
so
n+d=60
n+26=60
n=34
34 nickles and 26 dimes
