Answer:
4
Step-by-step explanation:
Given :
10 grams of 15% sugar syrup;
25 grams of 10% sugar syrup
Therefore,
(10grams * (15/100)) + (25 grams * (10/100))
(10 * 0.15) + (25 * 0.1)
1.5 + 2.5
= 4 grams
Answer:
Step-by-step explanation:
You'll use similar triangles to solve this. Set up 2 ratios as a proportion. First, however, you have to convert the 15 inches to feet. If everything else is in feet, then EVERYTHING has to be in feet. 15 inches is equal to 1.25 feet. Now for the equation:

The first fraction is made up of the heights, 3 being the height of the plumb bob and x being our unknown height of the flagpole; the second fraction is made up of the distances on the ground. Cross multiply to solve:
1.25x = 18 so
x = 14.4 feet, or 14 feet, 4.8 inches
add the like terms
14x=-3+x
subtract x from both sides
13x=-3
divide both sides by 13
x=-3/13
Answer:
90^
Step-by-step explanation:
Lets consider SAM's age is 'x' and Hank's age is 'y'
So as per given data Sam's age is 5/3 times of Hank's age
so x = 5/3 * y
3x = 5y --> equation 1
and also sum of their ages is 24
so, x + y = 24
we need to find Hank's age (y)
so x = 24 - y
Now replace x value in equation 1
3(24-y) = 5y
72-3y = 5y
72 = 3y+5y
8y= 72
y= 72/8
y = 9 years.
So the Hank's age is 9 years
