Answer:
25 gallons
Step-by-step explanation:
Given:
total no. of gallons= 50
Percentage of sulfuric acid= 50%
Number of gallons of sulfuric acid= total no. of gallons x Percentage of sulfuric acid
Putting values in above equation:
Number of gallons of sulfuric acid= 50 x 50/100
= 50 x 1/2
= 25 !
So if for every 10 pounds you get 12.70 which is 10:12.70 divide it it
its what I would do
3/2 ÷ 1/4 is 3/2 x 4/1 (the reciprocal)
Since 3/2 is the same as 1 1/2 we are asking how much are 4 x 1 1/2
Think money
1 1/2 is like $1.50
If I had $1.50 two times - I'd have $3.00
If I had $1.50 four times - I'd have twice as much or $6.00
Now I know that 6 is between 5 and 7 so answer c. is correct
You could also just multiply 3/2 x 4/1 but I think my explanation helps you understand it better than just using the multiplication algorithm.
Answer:
x=17
Step-by-step explanation:
The total degree of a hexagon is 720 degrees.
720-110-116=494.
(8x-1)+(6x-2)+(7x+19)+(5x+36)=494
x=17.
