<em><u>Question:</u></em>
? Liter equivalent to 0.000 000 000 013 cubic kilometers
How do we do it?´
<em><u>Answer:</u></em>
13 liter is equivalent to 0.000 000 000 013 cubic kilometers
<em><u>Solution:</u></em>
Given that,
? Liter equivalent to 0.000 000 000 013 cubic kilometers
So we have to convert cubic kilometer to liter
<em><u>Use the following conversion factor</u></em>

Therefore,

Thus, 13 liter is equivalent to 0.000 000 000 013 cubic kilometers
F(x)=(x-8)/7
<span>g(x) = 7x + 8
</span>g(f(x))-------------- > 7*((x-8)/7)+8----------- >x-8+8=x
the answer is x
Answer: 890.12 cm^3
Step-by-step explanation:
The formula for the volume of a cylinder is

V=628.3185307 cm^3
or simply
V=628.32 cm^3
Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.
Next, the formula for the volume of a sphere is

so the volume of a hemisphere is half of that or:

V= 261.7993878 cm^3
or simply
V=261.80 cm^3
Finally, you add both of the volumes together to get
V= 890.1179185 cm^3
or simply
V=890.12 cm^3
Answer:
37
Step-by-step explanation:
Let the answer be represented by xy where x is the tens digit and y is the ones digit.
The ones digit of a two-digit number is 4 more than the tens digit.
y = x+4
the sum of that number and the number reversed is 110
xy+yx = 110
Lets rewrite this vertically
x y
y x
------
1 1 0
We can replace y with x + 4 I will put the 4's in a separate row up top for ease of writing
4 4
x x
x x
------
1 1 0
Taking the one's column, we get
2x +4 = 0 and I will assume there is a carry of 10
so rewriting
2x+4 = 10
Subtract 4 from each side
2x+4 -4 = 10-4
2x =6
Divide each side by 2
2x/2 = 6/2
x=3
We still need to find y
y = x+4
Substituting in x
y = 3+7
y =7
The number is xy
