3 gallons of acid = 100% concentration acid
? (water+acid) gallons = 15 concentration acid
Note: Every gallon of water added reduces the percentage concentration of acid. Therefore, the relationship is inverse proportionality.
Solution:
Total number of gallons (water+acid) = (3*100)/15 = 20 gallons
Therefore, gallons of water = 20-3 = 17 gallons
Answer:
5
Step-by-step explanation:
Add the given numbers to the last recorded temp and see what is closest to 100 degrees.
95.5 + 6.5 = 101.5
95.5 + 6.6 = 102.1
95.5 + 5.5 = 101
95.5 + 5 = 100.5
So the closest to 100 degrees would be 5.
This is a typical algebra problem pretending to be geometry. The two indicated angles are supplementary, adding to 180 degrees, precisely when the lines are parallel.
It's not really indicated, but the 8 and the 2 are in units of degrees.
6x + 8 + 4x + 2 = 180
10x = 170
x = 17 degrees
Left Side Triangle: x = 142°
Top Middle Triangle: x = 136°
Bottom Middle Triangle: x = 26°
Right Side Triangle: x = 54°
