Amodel rocket is 3 inches long. the real rocket is 120 ft long. what is the unit rate that describes the relationship of the real rocket to the model rocket?
a. 360 ft/in
b. 360 in/ft
c. 40 ft/in
d. 40 in/ft

40 ft/in

Step-by-step explanation:

There is 40 feet for every inch of the model

Option C

40 ft/in

Step-by-step explanation:

We know that:

model rocket = 3 inches long

real rocket = 120 ft long

To find the unit rate that describes the relationship of the real rocket to the model rocket, you must divide the length of the real rocket by the length of the model rocket:

This means that every inch in length of the model rocket equals 40 feet of real rocket length

The answer is the option C

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
