George's cost per day is
... c = 30 + 0.18m
We want c < 55, so we can write
... 30 + 0.18m < 55 . . . . . your inequality
_____
Here is the solution to the inequality
... 0.18m < 25
... m < 25/0.18
... m < 138.9
George must drive less than 138.9 miles that day.
Answer:
work output is always less than work input - the ratio is less than 1.
Step-by-step explanation:
This principle comes from the fact that a machine or system cannot produce more work than is supplied to it, because this would violate the energy conservation law (work is a type of mechanical energy).
In theoretical machines called "ideal machines" the input work is the same as the output work, but these machines are only theoretical because in real applications there is always some type of energy loss, either in heat produced by a machine or processes for its operation, for this reason the output work is always less than the input work.
Regarding the ratio work output to work input:
WO/WI<1
because work input WI is always greater than work output WO.
Given:
63 tomato plants
81 rhubarb plants
63 / 9 = 7
81 / 9 = 9
ANSWER: The greatest number of rows Li Na can plant is 9 rows with 7 tomato plants and 9 rhubarb plants per row.
I hope this helps!
The answer is -60.
Why is this so??
The information we have here is that Rafeal rode his bike downhill by 6 kilometers.
Every kilometer he rides his bike, the altitude declines by 10m (meters)
let <em>m</em> represent how many meters the altitude declined.
If there is a positive number (ex. 2) multiplied by a negative number (-2), The result will be negative (-4) and vice-versa.
Same goes with division. positive number (4) divided by negative number (-2), the result will be a negative quotient.
<em>Therefore, the answer would be -60m, or -60 meters.</em>
