1000 = x^3
1000 cube root = x
10 = x
10*10 = 100
100*10 = 1000
Hope this helped, and please make me brainlest! :)
Answer:
1.28 minutes
Step-by-step explanation:
Given data
Speed= 7 meters per minute
Distance= 8.96 meters
We know that the expression for the Speed, Distance, and time is given as
Speed= Distance/Time
TIme= Distance/Speed
Substitute
Time= 8.96/7
Time= 1.28 minutes
Answer:
16.34
Step-by-step explanation:
To find the answer, you multiply 3.8 (how much is in one gallon) by 4.3 (number of gallons) to get the answer of 16.34.

Cups = c
Plates = p
6p + 5c = 23.80 ==> multiply by 6 ==> 36p + 30c = 142.80
7p + 6c = 28.00 ==> multiply by 5 ==> 35p + 30c = 140.00
Now use algebra to have the 30c be on one side and the rest on the other:
36p + 30c = 142.80 | -36p
30c = 142.80 - 36p
35p + 30c = 140.00 | -35p
30c = 140.00 - 35p
Now set them equal to each other about the 30c:
142.80 - 36p = 140.00 - 35p
Use algebra to solve for p:
142.80 - 36p = 140.00 - 35p | +36p
142.80 = 140.00 + p | - 140
2.80 = p
Go back to one of the "30c" equations and plug in the value for p:
30c = 140 - 35p
30c = 140 - 35(2.80)
30c = 140 - 98
30c = 42 | /30
c = 42/30
c = 1.4
Plates are $2.80
Cups are $1.40
