Answer:
3/2
Step-by-step explanation:
A couple of different methods are used for dividing fractions.
1. "Invert and multiply". Dividing by a number is the same as multiplying by its reciprocal:
(3/4) / (1/2) = (3/4) × (2/1)
= (3·2)/(4·1) = 6/4 = 3/2
__
2. Make the denominators the same and use the ratio of numerators.
(3/4) / (1/2) = (3/4) / (2/4) = 3/2
_____
For these fractions, you can recognize that 3/4 is 1/4 more than 1/2, and that 1/4 is half of 1/2. That means 3/4 is half-again as much as 1/2, so is 1 1/2 = 3/2 times 1/2. This tells you the ratio (3/4) : (1/2) = 3/2.
__
Along the lines of the above, you can write the ratio as ...
(3/4) : (1/2)
and multiply by 4 to get
= (3/4)×4 : (1/2)×4 = 3 : 2
Answer:
f(5) = 2
Step-by-step explanation:
it says to use the function (-x+3) for when x is bigger than 2
f(x) = (-x) + 3 replace x with 5
f(5) = (-5) + 3 and f(5) = 2
The volume of the baseball is <span>65.8
r = 1/2 d
r = 1/2 5.1
r = 2.505
</span>V = 4/3 π r^3
V = 4/3 π 2.505^3
V = 65.8
I hope this helps!

Step-by-step explanation:
<h2>Area of scalene triangle:</h2>

Here, a, b and c are the sides of the triangle. s is the semi perimeter.
a = 13
b = 14
c = 15

s -a = 21 - 13 = 8
s -b = 21 - 14 = 7
s - c = 21 - 15 = 6
