The uss enterprise was 1,123 feet in length.
a. what is the scale for a model that is 30 inches long?
b. what is the scale for a model that is 2 feet long?

The total length is 1123 feet.

a) if the model is 30 inches long, the first thing we need to do is write inches in feets, so 1 feet is equivalent to 12 inches.

so 30 inches are 30/12 = 2.5 feets.

the scale is the ratio between the feets in the the two lengths.

1123/2.5 = 449.2

so the scale is 1:449.2

so each feet in the model is equivalent to 449.2 feets in the enterprise.

b) if the model is 2 feet long, then:

1123/2 = 561.5

the scale is 1:561.5

so each feet in the model is equivalent to 561.5 feets in the enterprise.

da freeck kinda math is this just drop out

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
