Suppose a bay window is a perfect semicircle with an area of 4.5 square feet. if the architect wants to use a scale of 0.5 inch = 1 ft on the floor plan, what is the radius of the bay window on the floor plan? a) 0.85 inches b) 1.7 inches c) 3 inches d) 3.4 inches

The answer is A) .85 inches

Step-by-step explanation:

A =  

1 /2 πr2 4.5 =  1 2 πr2  1.6926 = r

  thus, 0.50 in  

1 ft  =  x in 1.6926 ft x = 0.8463

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
