The scale of a model train is 1 1 inch to 13.5 13.5 feet. One of the cars of the model train is 5 5 inches long. What is the length, in feet, of the actual train car?

Answers

Answer:

74.25feet

Step-by-step explanation:

Given the scale of a model train expressed as;

1in = 13.5feet

We are to express length of 5.5in in feet

5.5in = x

Divide both expressions

1/5.5 = 13.5/x

Cross multiply

1×x = 5.5× 13.5

x = 74.25feet

Hence the actual length of the car in feet is 74.25feet

Pleasss help thank you :)

Answers

Answer:

The answer is 68 and 52

Step-by-step explanation:

x + y = 120

3(x - y ) = 48

We have 3x + 3y = 360

and 3x - 3y = 48

Adding we have the following:

6x = 408

x = 68

y = 120-48 = 52

In the oak forest, 60 kids are playing capture the flag.That is 40 percent of all kids in the park.How many kids are in the park?

Answers

Answer:

150 kids

Step-by-step explanation:

If 60 kids is 40% of the total kids, we can add another 60 to get 80% and then half of 60 (30) to bring the total up to 100% of the kids.

150 kids because if you did the percents right then you would get the total and then divide it

Line segment JK is divided by point L in the ratio of 3:2. Endpoint J is at (-16, 2) and point L is at (-15, -20). What are the coordinates of endpoint K?

Answers

9514 1404 393

Answer:

  K(-14 1/3, -34 2/3)

Step-by-step explanation:

The division ratio says ...

  (L -J)/(K -L) = 3/2

  2(L -J) = 3(K -L)

  5L -2J = 3K

  K = (5L -2J)/3

  K = (5(-15, -20) -2(-16, 2))/3 = (-75+32, -100-4)/3 = (-43/3, -104/3)

  K = (-14 1/3, -34 2/3)

7x + 5 = 3(2x + 3) + x - 4​

Answers

Answer:

Infinite Many Solutions

0 = 0

Step-by-step explanation:

7x + 5 = 3(2x + 3) + x - 4​ (Given)

7x + 5 = 6x + 9 + x - 4 (Distributive Property Of Equality)

7x + 5 = 7x + 5 (Combine Like Terms)

0 = 0 (Subtraction Property Of Equality)

As you see it's the same thing in both sides and if you solve it gives 0 = 0 because it would cancel each other out and since 0 is equal to 0 it's infinite many solutions.
