The scale on a model railroad train set is 3.5 millimeters to 1 foot. If the length of a model car in the set is 150 millimeters

Vera_Pavlovna [14]

Answer:

The approximate length of the actual car is 43 feet.

Step-by-step explanation:

Given:

The scale on a model railroad train set is 3.5 millimeters to 1 foot. If the length of a model car in the set is 150 millimeters.

Now, to find the approximate length of the actual car.

Let the actual length of the car is $x.$

The length of a model car in the set is 150 millimeters.

As, given the scale on a model railroad train set is 3.5 millimeters to 1 foot.

So, 3.5 millimeters equivalent to 1 foot.

Thus, 150 millimeters to $x$ .

Now, to get the actual length of the car by using cross multiplication method:

$\frac{3.5}{1} =\frac{150}{x}$

By using cross multiplying we get:

$3.5x=150$

Dividing both sides by 3.5 we get:

$x=42.85\ feet.$

The approximate length of the actual car = 43 feet.

Therefore, the approximate length of the actual car is 43 feet.

Find the coordinates of the point seven-tenths of the way from A to B

bezimeni [28]

Answer:

the x distance is 9 - -4 = 9+4 = 13

7/10 of that is 91/10 = 9.1

-4 + 9.1 = 5.1

the y-distance is 6 - -5 = 6+5 = 11

7/10 of that is 77/10 = 7.7

-5 + 7.7 = 2.7

so ( 5.1, 2.7) is hte point that is 7/10 of the distance. Please label this point M.

the distance of AB is sqrt( 11^2 + 13^2) = sqrt(121+169) = sqrt(290) , or approximately 17.0294

the distance from A to M is sqrt( 9.1^2 + 7.7^2) , or approximately 11.92

the quotient of these distances is 0.7 approximately

Step-by-step explanation:

Find the coordinates of the point seven tenths of the way from A to B.

the coordinates of b is (-4,-5)

the coordinates of a is (9,6)
