The USS Enterprise was 1,123 feet in length.

Kitty [74]

Answer:

The scale for a model that is 30 inches long is 449.2 inches.

The scale for a model that is 2 feet long is 561.5 feet.

Step-by-step explanation:

Consider the provided information.

The USS Enterprise was 1,123 feet in length.

Part (A) What is the scale for a model that is 30 inches long?

1 feet = 12 inches.

First convert the length of USS enterprise in inches.

1×1,123 feet = 12×1,123 inches

1,123 feet = 13476 inches

Divide original length with the length of model.

The scale for the model is:

$\frac{13476}{30}=449.2\ inches$

Hence, the scale for a model that is 30 inches long is 449.2 inches.

Part (B) What is the scale for a model that is 2 feet long?

Since, both the units are in feet, so simply divide original length with the length of model.

The scale for the model is:

$\frac{1123}{2}=561.5\ feet$

Hence, the scale for a model that is 2 feet long is 561.5 feet.

0.661 rounded to nearest hundretg

elena-s [515]

Since you are doing decimals, know that you are mirroring what you would do on the left side

Your decimal number: .661

The first 6, which is .6 is the tenths place

The second 6, which is .06 is the hundredths place

1 which is .001 is the thousands place

The farther you go left, the bigger the digit number value

So when rounding up, you look at the digit after the number you are rounding

So what is after the hundredths place? Its the thousandths place which is 1

Is 61 closer to 60 or 70? Since 1 is smaller than the halfway point which is 5, its closer to 60

Answer: .661 rounded to the nearest hundredths is .660 or just simply written as .66

write the equation of the line that passes through the points (3, 6)and (5, 18) using function notation.

Delvig [45]

Ok basically slope can be found by doing one y value - the other y value divided by one x value - the other x value. so in this it would be (18-6) divided by (5-3) which is 12 divided by 2, which is 6. So slope = 6.

6 = 6(3) + b
6 = 18 + b
-12 = b

f(x) = 6x-12
