Answer:
Step-by-step explanation:
The ratio of areas of similar figures is the square of the scale factor. Then we have ...
larger/smaller = √(6800/17) = √400 = 20
The dimensions of the larger triangle are 20 times those of the smaller triangle.
x mm = 20(7.5 mm)
x = 150
__
20(y mm) = 80 mm
y = 4
The interquartile range, IQR, is equal to the difference of Q1 and Q3 (first and third quartiles). These markers are visually shown as the edges of the box.
IQR = Q3 - Q1
IQR = 36 - 16
IQR = 20
Final Answer: Choice D) 20
The percent of increase is 90%
Y - y1 = m(x - x1)
slope(m) = -8/7
(4,4)...x1 = 4 and y1 = 4
sub
y - 4 = -8/7(x - 4) <== answer C
