Answer:
The total length of the trip was 400 miles.
Step-by-step explanation:
He fell asleep at 44% through the trip, they already had traveled 176 miles.
.44x = 176 ⇒
176 ÷ .44 ⇒
x = 400
Jenny traveled 70 km/h over 2 hours and 63 km/h over 5 hours. Her travel time was a total of 7 hours.
We need to find out how far she traveled during this 7-hour period.
70 km/h * 2 h = 140 km
63 km/h * 5 h = 315 km
Then, we can add 140 km and 315 km to get a total distance traveled of <em>455 km/h.</em>
We were asked to find the average <em>speed.</em> We can find it now, since we have total distance traveled (455 km) and total time taken (7 hours).
Then,
455km / 7h = 65 km/h.
Answer:
524.96 − 32.50 + x ≥ 500
Amount need to deposit = $7.54
Step-by-step explanation:
Given:
Amount in checking account = $524.96
Maintain amount = $500
Amount of check = $32.50
Find:
Amount need to deposit
Computation:
Assume, amount need to deposit = x
So,
For avoiding fee
524.96 − 32.50 + x ≥ 500
x = 7.54
Amount need to deposit = $7.54
Answer:
Vacation pays are not included in salaries. Therefore, Jerry's calculation is wrong.
Step-by-step explanation:
Given is :
Jerry makes $40,000 a year working at a nearby factory.
He gets two weeks paid vacation per year, plus five other paid holidays.
So total paid holidays become =
days
Subtracting 19 from 365 days and assuming that Jerry works for 365 days a year.
We get =
days
So, his per day salary will be = 
Vacation pays are not included in salaries. Therefore, Jerry's calculation is wrong.
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x -----> the number of open acres
y ----> the number of developed acres
we know that
-----> inequality A
----> inequality B
Remember that
if the number of open acres, x, can be no more than 1. then the number of open acres, x must be less than or equal to 1
Solve the system of equations by graphing
The solution is the shaded area (Note The number of acres cannot be a negative number)
