Janie mad a 2.5 inch scale model of one of the tallest buildings in the world: Taipei 101. The scale for the model is 1/4 inch= 167 feet. Find the actual height of Taipei 101.

1,670 feet

Step-by-step explanation:

Given that the scale is

1/4 inches : 167 feet, i.e

1/4 inches (model) --> equivalent to 167 feet (actual)   (multiply both sides by 4)

1 inch (model) --> equivalent to 167 x 4 = 668 feet (actual)

2.5 inch (model)--> equivalent to 668 x 2.5 = 1,670 feet

your answer would be 10x - 1

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
