The answer is the store has 240 melons.
(30x4)x2=240
3x9=27
21/3 = 7
so
7+27x9+5
27x9=243
243+7+5
answer is 255
Since they are just next to each other ill take it multiplication and that would be 128 if its not let me know and ill correct it
The volume of a cube (V) is given in terms of its side length (s) as
... V = s³
You have
... 27n²⁷ = s³
You may recognize that 27 = 3³, so this can be written as
This result matches your second selection
... 3n⁹ units
Answer:
2.8 hours
Step-by-step explanation:
Distance = rate * time
If the west-bound train travels at a rate of 80 mph for t hours, then the distance it travels is 80t.
If the east-bound train travels at a rate of 90 mph for t hours, then the distance it travels is 90t.
The distance between the trains after t hours is 476; therefore, the distance of the west-bound train plus the distance of the east-bound train equals the total distance between them, 476:
80t + 90t = 476 and
170t = 476 so
t = 2.8 hours
