Answer:
264 miles
Step-by-step explanation:
Using the relation ...
distance = speed · time
we can rearrange to get ...
speed = distance/time
We can choose to let d represent the distance we want to find. Then Jina's speed going to the mountains is d/6. Her speed coming home is then d/6+22. It takes Jina 4 hours at that speed to cover the same distance, so we have ...
d = 4(d/6 +22)
d = 2/3d +88 . . . . eliminate parentheses
1/3d = 88 . . . . . . . subtract 2/3d
d = 264 . . . . . . . . . multiply by 3
Jina lives 264 miles from the mountains.
7:3=8:x is like like 7/3=8/x
so 7x=24
24/7=x
x=~3.43
Exact Form:
4/9
Decimal Form:
0.4
Sum of cubes: a^3 + b^3 = (a+b)(a^2 - ab + b^2)
Sum of cubes: x^3*y^3 + 34, or (xy)^3 + (∛34)^3
This factors into (xy + ∛34)*( [xy]^2 - xy∛34 + (∛34)^2 )
If the base has an area of 8, and we’re dealing in whole numbers, then the dimensions of three of the chests are 2x2x4. The last one is 2x3x4. Just multiply the dimensions by each other to find the volume of one unit, and then add them all together. Hope that helps!
