Answer:
12:42 (approximately)Step-by-step explanation:
Train 1 will travel for 2 hours before the second train leaves.
The distance at 2 o'clock is reduced by 2*90 = 180 miles and now is:
2000 - 180 = 1820 milesLet the trains spend x hours before crossing, then we have following equation for the distance:
x(90 + 80) = 1820170x = 1820x = 1820/170x = 10 120/170 = 10 12/17 hours ≈ 10 hours and 42 minutesThe trains will cross at:
2 o'clock + 10 h 42 min = 12:42The time when trains cross each other will be approximately 12:42

Jimmy is selling used books at a yard sale. A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill. Jimmy must determine c, the amount of change in dollars he should give the customer. Which equation represents c?
20 minus 0.75 c = 9
20 minus 0.75 = 9 c
0.75 (9) + c = 20
0.75 c + 9 = 20
Answer:
c

Answer: immy is selling used books at a yard sale. A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill. Jimmy must determine c, the amount of change in dollars he should give the customer. Which equation represents c?
20 minus 0.75 c = 9
20 minus 0.75 = 9 c
0.75 (9) + c = 20
0.75 c + 9 = 20
C / 0.75 (9) + c = 20
Step-by-step explanation:
To find your change, first you must determine how much the customer is paying. To find this, you must multiply the cost of one book by the number of books bought.

At the gym, Tika spends twice as much time doing aerobics than weight training. She stretches for one fifth of the time she spends on weight training. Let w be the amount of time Tika spends on weight training. Which expression represents her total workout?
Answer:
Her total workout is [tex]2w+w+\frac{w}{5}[/tex].
Step-by-step explanation:
Consider the provided information.
Let w be the amount of time Tika spends on weight training.
Tika spends twice as much time doing aerobics than weight training.
It means she spends [tex]2w[/tex] time doing aerobics.
She stretches for one-fifth of the time she spends on weight training.
It means she spends [tex]\frac{w}{5}[/tex] time for stretches.
The total workout time is:
[tex]2w+w+\frac{w}{5}[/tex]
Hence, her total workout is [tex]2w+w+\frac{w}{5}[/tex].

what is the period of the sinusoidal function
Answer:
10Step-by-step explanation:
Period is the distance between two consecutive maximum points, or two consecutive minimum points.On the given graph the period is the distance between maximum points -7 and 3:
3 - (-7) = 10Answer:
The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.
From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units
Therefore, 10 units is the right answer.

Which of the following statements is true?
A The system has infinite solutions
OB. The solutions to the system are (0, 1) and (0, -3)
C The solution to the system is (-4,3)
OD The system has no solution
Answer:
The correct answer is Option C: The solution to the system is (-4,3)
Step-by-step explanation:
We can observe the graph to find the solution of the system.
There are three solutions to a system of equation
One solutionNo solutionInfinite many solutionsIn the given graph we can see that the two lines are only intersecting at one point so the system of equations has only one solution.
Observing the graph, we can see that the intersection point is (-4,3)
Hence,
The correct answer is Option C: The solution to the system is (-4,3)
