Answer:
0.875
Step-by-step explanation:
Answer:
let the unit digit be x
and the tens digit be y
so x+y = 9 ---> y = 9-x
the number is 10y+x
the number reversed is 10x + y
3(10y+x) = 8(10x + y)
30y + 3x = 80x + 8y
22y = 77x
2y = 7x
2(9-x) = 7x
18 - 2x = 7x
18=9x
x=2
y=7
the number is 72
check:
number is 72
reverse is 27
is 3(72) = 8(27)
Assuming your looking for volume.
The following formula is used for calculating the volume (V) of a cone.

- where r is the radius and h, the height.
- Substitute r = 3 and h = 5 into the formula.

Answer:
d=2
Step-by-step explanation:
3d + 6 = 12
first subtract 6 from both sides
3d=6
divide by 3 on both sides
d=2
6/10 is the closest to zero because if you simplify all the fractions you can, then convert them into decimals, you can easily find what is closer to zero:
8/12 = 2/3 = 0.66
5/8 = 0.62
6/10 = 3/5 = 0.60
2/3 = 0.66
0.60 or 6/10 is the smaller number ;))
