An architect has a blueprint of a movie theatre he is designing using a scale of 12ft:6 in. After the theatre is built, the screen will be 30 feet high. What is the height of the screen
on the blueprints

a. 15 inches
b. 125 inches
c. 72 inches

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
