An Eastbound train (E) traveling 95 mph and a Westbound train (W) traveling 110 mph leave the same train station at different times. After 4 hours, they are 4 00 miles apart. Which system of linear equations can be used to determine the time that each of the trains has been traveling?

Answers

Answer:

The system of linear equations that can be used to determine the time that each of the trains has been traveling is:

E + W = 4 ....... Equation 1

95 E + 110W = 400  ......Equation 2

Hence,

An Eastbound train has been travelling for =  (E) = 2.67 hours

A Westbound train has been travelling for =  (W) = 1.33 hours

Step-by-step explanation:

An Eastbound train (E) traveling 95 mph and a Westbound train (W) traveling 110 mph leave the same train station at different times. After 4 hours, they are 4 00 miles apart. Which system of linear equations can be used to determine the time that each of the trains has been traveling?

Speed = Distance/Time

Distance = Speed × Time

Let the time

An Eastbound train =  (E)

A Westbound train =  (W)

E + W = 4 hours ....... Equation 1

95mph × E + 110mph × W = 400 miles

95 E + 110W = 400 miles ......Equation 2

The system of linear equations that can be used to determine the time that each of the trains has been traveling is:

E + W = 4 ....... Equation 1

95 E + 110W = 400  ......Equation 2

E = 4 - W

We substitute 4 - W for E in Equation 2

95 (4 - W) + 110W = 400  

380 - 95W + 110W = 400

Collect like terms

95W - 110W = 400 - 380

15W = 20

W = 20/15

W = 1.3333333333 hours

≈ 1.33 hours

E = 4 - W

E = 4 - 1.33 hours

E = 2.67 hours

Therefore,

An Eastbound train has been travelling for =  (E) = 2.67 hours

A Westbound train has been travelling for =  (W) = 1.33 hours

How to tell if your table is linear or exponential?

Answers

Answer: If the first difference is the same value, the model will be linear. If the second difference is the same value, the model will be quadratic. If the number of times the difference has been taken before finding repeated values exceeds five, the model may be exponential or some other special equation.

Step-by-step explanation: You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference. This table is linear.

68 lb 13oz - 30 lb 15 oz=

Answers

Answer:

37.875 lb (37 lb 14 oz)

Step-by-step explanation:

(There are 16 oz in 1 lb)

68 lb = (68 x 16 =) 1,088 oz

1,088 oz + 13 oz = 1,101 oz

30 lb = (30 x 16 =) 480 oz

480 oz + 15 oz = 495 oz

1,101 oz - 495 oz = 606 oz = (606 oz ÷ 16 =) 37.875 lb

Final answer:

37.875 lb (37 lb 14 oz)

Pauline Romer has taken a $100000 mortgage loan on her house at an interest rate of 3 percent per year. If the mortgage calls for 20 equal annual payments, what is the amount of each payment?

Answers

Answer:

5000

Step-by-step explanation:

Using the mortgage interest principle, the amount of equal payment to be made ls $8000

Mortgage payment = $100000

Interest rate = 3%

The total amount to repayed can be calculated thus :

Mortgage payment × interest rate × time

Number of annual payments = 20

Total repayment = 100000(1 + (0.03 × 20))

Total repayment = 100000 + 60000 = $160,000

Amount of each payment = $160000 / 20 = $8000

Therefore, the amount to be repayed annually is $8000

Elliot collects miniature toy cars. He wants to fill 4 display cases.each display case holds 15 cars. He has 28 cars now, and he is able to buy 3 more every month with the money he saves from his allowance. How many more months will it be until elliot has enough cars to fill all 4 display cases?

Answers

Answer:

Elliot has to wait 11 months before he has enough cars

Step-by-step explanation:

Elliot has 4 display cases with each case being able to hold 15 cars. Thus we know

total # of cars Elliot can place in his display case = 4 * 15 = 60 cars

From this, we can figure out how many more cars Elliot needs by subtracting the amount of cars he already has

# of cars Elliot needs = 60 - 28 = 32 cars

Now to find the number of months Elliot needs, we divide by how many he can buy each month

# of months Elliot needs to save up for = 32 / 3 = 10 2/3

Assuming Elliot does not get his allowance until the end of the month, we will have to round the number of months up to the nearest integer, 11

How far will 25 N of force stretch a spring with a spring with a spring constant of 125 N/m?​

Answers

Answer:

-0.656168ft

Step-by-step explanation:

If Spring force constant (k)  is 125  N/m

And the force is (F) 25 N ,

then the spring displacement (Δx) -0.656168

Equation used:

Knowing Hooke's law, we can write it down it the form of a formula:

F = -kΔx

F is the spring force (in N);

k is the spring constant (in N/m); and

Δx is the displacement (positive for elongation and negative for compression, in m).

In the background, a man uses a jump rope. A woman does push-ups. (CAIN, a small boxer, sits on a bench unwrapping the protective tape off of his knuckles and wrists using his teeth. SERGIO, his sparring partner and best friend, cuts away at the tape on CAIN'S other hand.)SERGIO: I know you've got a hand in there somewhere.CAIN: (spitting the tape out of his mouth) Well, remember to stop cutting once you see bone. (The people exercising in the background finish their workouts and move off stage, leaving the focus of the audience on CAIN and SERGIO.)SERGIO: Right, like you'd be able to feel it otherwise. I don't even think you have bone in there. I think you've got anvils in your hands.CAIN: Are you kidding? I'll need more than anvils come fight night. Doerkson is a monster in the ring. To bring him down, I'll need a lead pipe and a tank if you can spare them. (Freed from the cast of protective tape, CAIN'S hands start to violently shake. CAIN closes them into a fist until they calm.)SERGIO: What was that? (CAIN stands up and walks over to a nearby heavy bag and starts to throw light jabs.)CAIN: It's nothing, just nerves.
