Given
Alchemist wishes to mix a solution that is 10% acid.
She has on hand 6 liter of a 8% acid solution and wishes to add some 16% acid solution to obtain the desired 10% acid solution. H
To find: ow much 146 acid solution should she add?
Explanation:
It is given that,
Alchemist wishes to mix a solution that is 10% acid.
Let x be the amount o acid mixed to obtain the desired 10% solution.
Since she has on hand 6 liters of a 8% acid solution and wishes to add some 16% acid solution to obtain the desired 10% acid solution.
Then,
Hence, she should add 2 liters of acid solution.
Answer:
Total length of the road = 6 3/4 miles.
Each markers are spaced at a distance = 1/8 of a mile.
Step-by-step explanation:
Total length of the road ÷ each marker space =
a) 6 3/4 ÷ 1/8.
b) In order to solve it, we need to convert that fraction into improper fraction:
6 3/4 = 27/4
6 3/4 ÷ 1/8 = 27/4 ÷ 1/8
We need to convert division sign into multiplication sign and flip the second fraction.
27/4 × 8/1
then simplify to get
27 × 2 = 54.
There would be total number of 54 markers of lengths (1/8) of a mile.

Answer:
83.4
Step-by-step explanation:
Area of a Regular Polygon: L (of side) times apothem (height) x 1/2
L : 13.9
Looking at the triangle we can assume the height would be 12 since its logical that 3 of the 4 lines can fit in the middle of the triangle.
H: 12
13.9 x 12 = 166.8
166.8/2 = 83.4
