-1,3 that’s easy u should definitely pay attention in class
UT = 3 √3
A = 1/2 *12 * 3√3 = 18√3
18√3 = 6y/2
y = 6√3
Answer:
48
Step-by-step explanation:
The fraction who picked apples is the rest of the students:
1 - 5/8 = 3/8
of them.
So the number who picked apples relative to the number who picked bananas is ...
apples/bananas = (3/8)/(5/8) = 3/5
Multiplying this by the number who picked bananas gives the number who picked apples:
apples = bananas · 3/5 = 80·3/5 = 48
48 students picked apples.
____
<em>Alternate solution</em>
Let "a" represent the number who picked apples. The ratio of banana choosers to the total is 5/8, and there were 80 who chose bananas. That gives rise to the equation ...
80/(80 +a) = 5/8
640 = 400 +5a . . . . . . multiply by 8(80+a) and simplify
240 = 5a . . . . . . . . . . . subtract 400
240/5 = a = 48 . . . . . . divide by 5
48 students picked apples.
The answer would be B because it's saying sum which means adding then it says less which means subtracting.
Answer:
His collection increased in a 20%.
Step-by-step explanation:
If 100% represents 10 records, what percentage would be for 12 records?
x = 12 100% / 10 = 120%
So, if we subtract 120% - 100%, it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.
