Answer:
V = 115.3 ft³
Step-by-step explanation:
The left part of the figure shows a cube of side length 4.2 ft. The volume of a cube is V = s³, where s is the side length. Hence, the volume of this particular cube is V = (4.2 ft)³ = 74.088.
The volume of a pyramid is V = (1/3)(base area)(height).
Here V = (1/3)(4.2 ft)²(7 ft) = 41.16 ft³.
Summing up the two distinct areas, we get V = 41.16 ft³ + 74.088 ft³, or
V = 115.3 ft³ after rounding up to the nearest tenth.
3 × 100 = 300
the easiest way to do it is just add the same amount of zero's to the number you multiplied with. for example
3 × 10000 if you would just take out the zero's
it would look like this. 3 × 1
the answer of course would be 3 then you can put the zero's back in the answer (30000)
at least that's how I understood it
3 × 100 =
3 × 1(00) =
-->
-->
(00)
3 × 1(00) = 3
3 × 100 = 300
For this question we can solve it by setting up a proportion:

Now we can solve for x to find the total distance between the towns. Let's cross multiply and solve for x:


So now we know that
the total distance between the towns is 42.5 miles.
