A two-story building measures 21 feet from the ground. A scale model shows the building
to be 3 inches tall. How many inches would an
84-foot building be in the model?

Step-by-step explanation:

Given,

Measure of a two-story building (in feet)

= 21 feet

So, Measure of the building in (in inches)

= 3 inches

Therefore,

By the problem,

21 feet building

= 3 inches

So,

1 feet building

Then,

84 feet building

= 3 × 4 inches

= 12 inches

Hence,

84 feet building will measure 12 inches (Ans)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
