Two trains leave stations 204 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at miles per hour. How long will it take for the two trains to meet?
Answers
Answer:
t = 1.23 hours
Step-by-step explanation:
Given that,
Distance between two stations is 204 miles
One train travels at 90 miles per hour while the other travels at 75 (let) miles per hour.
We need to find how long will it take for the two trains to meet.
As both cars travel toward each other, it means they approach with a speed of 90 mph + 75 mph = 165 mph.
Let t is the time when they meet. So,
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{204}{165}\\\\t=1.23\ h[/tex]
It will take 1 hour 23 minutes for the trains to meet.

You recently started your own company. Your first year in business, your company reported a net loss of $1,250. The next year, your company made a $3,475 net profit. The year after that, your company reported a $2,478 net profit. What was your company's net loss or gain over the last 3 years?
Answers
Answer:
$4703
Step-by-step explanation:
Given that :
First year :
Net loss = $1250
2nd year:
Net profit = $3475
3rd year :
Net profit = 2478
Net loss or gain over the last 3 years :
Let Net loss be represented as negative and net profit as positive
Net loss + net profit + net profit
(-$1250 + $3475 + $2478)
$4703 net gain over the last 3 years

If you are trying to decide whether a system of equations has a solution, would you rather have the equations or the graphs? Why?
Answers
When determining if the set of equations has a solution, this is when graphing is the best method to be used.
What are linear equations in two variables?If an equation is written in the form axe + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables.
When there is a system of equations, there are mainly three solutions for equations that are,
no solution, unique solution, and infinitely many solutions,
these solutions can be found by solving the equations or comparing their variables, hence the process takes more time,
but the same process for finding the solutions can be done by graphing method and it is easy as compared to the above method because,
As it offers the visual to record what they have actually looked for, it was seen to be the greatest way at the time it was taught to new students for solving the system of two equations in two variables.
Hence graph method is best to find the solution to equations.

Answers
Answer:
Step-by-step explanation:
Given: He needs 8ft and 6 ft
The trim costs 2.95 per foot
so if we do 8 times 2.95 we get 23.60
Next we do the same with 6 and we get 17.7
Add then together and we get $41.30

13. x = 21; y = 15
14. x = 8; y = 11
15. x = 16; y = 23
Step-by-step explanation:
13. (3x - 16)° + (6x + 7)° = 180° (same side interior angles are supplementary)
Solve for x
3x - 16 + 6x + 7 = 180
Collect like terms
9x - 9 = 180
Add 9 to both sides
9x = 180 + 9
9x = 189
Divide both sides by 9
x = 189/9
x = 21
(6x + 7)° = (11y - 32)° (vertical angles are congruent)
Solve for y by substituting x = 21 into the equation
6(21) + 7 = 11y - 32.
126 + 7 = 11y - 32
133 = 11y - 32
Add 32 to both sides
133 + 32 = 11y
165 = 11y
Divide both sides by 11
165/11 = y
15 = y
y = 15
14. (11x - 25)° = (8x - 1)° (alternate exterior angles theorem and corresponding angles theorem)
Solve for x
11x - 25 = 8x - 1
Collect like terms
11x - 8x = 25 - 1
3x = 24
Divide both sides by 3
x = 24/3
x = 8
(8x - 1)° + (15y - 48)° = 180° (linear pair theorem)
Substitute x = 8 into the equation and solve for y
8(8) - 1 + 15y - 48 = 180
64 - 1 + 15y - 48 = 180
15 + 15y = 180
Subtract 15 from both sides
15y = 180 - 15
15y = 165
Divide both sides by 15
y = 165/15
y = 11
15. (7x - 44)° = (4x + 4)° (alternate exterior angles theorem)
Solve for x
7x - 44 = 4x + 4
Collect like terms
7x - 4x = 44 + 4
3x = 48
Divide both sides by 3
x = 48/3
x = 16
39° + (8y - 43)° = 180° (corresponding angles theorem and linear pair theorem)
Solve for y
39 + 8y - 43 = 180
Collect like terms
-4 + 8y = 180
Add 4 to both sides
8y = 180 + 4
8y = 184
Divide both sides by 8
y = 184/8
y = 23

Jane contribuyó con $ 10,000 y Julie contribuyó con $ 6,000. Después de un año, la empresa obtuvo una ganancia de $ 4,000. ¿Qué proporción de las ganancias debería tomar Julie si se comparten en la misma proporción que sus contribuciones originales?
Answers
Answer:
Ganancias Julie= $1,500
Step-by-step explanation:
Dada la sigueinte información:
Jane contribuyó con $ 10,000 y Julie contribuyó con $ 6,000. Después de un año, la empresa obtuvo una ganancia de $ 4,000.
Primero, debemos calcular la proporción de aportes de cada una:
Jane= 10,000/16,000= 0.625
Julie= 6,000/16,000= 0.375
Ahora, lo que le corresponde a Julie de las ganancias:
Ganancias= 4,000*0.0375
Ganancias Julie= $1,500
Denver is planting strawberry seedlings in a new garden. He can plant 3 rows of a certain length with 2 seedlings left over or 4 rows of the same length with 3 seedling spots left empty. What is the length, x, of each row in meters?
Answers
Answer:
The length of each row is 5 m.
Step-by-step explanation:
It is given that,
Denver can plant 3 rows of a certain length with 2 seedlings left over and 4 rows of the same length with 3 seedling spots left empty.
Let the length of each row is x.
Case 1,
Total number of seeds = 3x+2
Case 2,
Total number of seeds = 4x-3
From both of the cases,
3x+2 = 4x-3
Taking like terms together,
3x-4x=-3-2
-x=-5
x=5
So, the length of each row is 5 m.
Write the number in standard form.

A car initially moving at 4 m/s accelerates to a new velocity of 10 m/s in a time of 3
seconds. What was the acceleration of the car?
Answers
Step-by-step explanation:
Hey there!
Given;
Initial velocity (u) = 4m/s
Final velocity (v) = 10m/s.
Time(t) = 3s
Acceleration (a) = ?
We know;
[tex]a = \frac{v - u}{t} [/tex]
Keep all values.
[tex]a = \frac{10 - 4}{3} [/tex]
Simplify it.
[tex]a = \frac{6}{3} [/tex]
Therefore, acceleration is 2m/s^2.
