3/5 or 60% of .25 is found by doing this.3/5 times x/.25.Cross multiply to get 5x = .75. Divide both sides by 5 to get .15. .25 - .15 is .10, or 1/10. The answer is 1/10 of a gallon.
So the range is that combined sugar and chocolate chips you can have [1,10/3] cups.
So far, you have already poured in three and three quarters which in improper fractions is 15/4. Multiply the y-range of the combined with 4, to get this:
12/12 => 40/12. Then multiply 15/4 by three to get 45/12. Clearly you see this that more cups of sugar than the limit is poured. you can only go to 40/12, but 45/12 is just sugar, so no chocolate chips can be added
Answer:
The sides are 5,18,16
Step-by-step explanation:
To find the perimeter of a triangle, we add up all the sides
n +4n-2 + 5n-9 = 39
Combine like terms
10n -11 = 39
Add 11 to each side
10n-11+11 = 39+11
10n = 50
Divide by 10
10n/10 =50/10
n = 5
Now we need to find each side
n = 5
4n-2 = 4(5)-2 = 20-2 =18
5n-9 = 5(5) - =25-9 = 16
The sides are 5,18,16
