the change in the scale factor is
.Correct option C) StartFraction 45 feet over 40 feet EndFraction
<u>Step-by-step explanation:</u>
Here we have , Norma Ann planned a rectangular courtyard, as shown in the scale drawing below. A rectangle with length of 15 inches and width of 5 inches. She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. We need to find Which expression finds the change in the scale factor . Let's find out:
Initially the ratio of width to actual width is :
⇒ 
Now , After 45 ft is changed to 40 ft , New ratio becomes :
⇒ 
So , change in scale factor is from
to
i.e.
⇒ 
⇒ 
⇒ 
Therefore , the change in the scale factor is
.Correct option C) StartFraction 45 feet over 40 feet EndFraction
Let d be the number of days and h be the height
h = 13 + 0.6d
Answer: (a) h = 13 + 0.6d
Given height = 0.208m, find d:
0.208m = 20.8 cm
20.8 = 13 + 0.6d
0.6d = 20.8 - 13 = 7.8
d = 7.8 ÷ 0.6 = 13
Answer: (b) 13 days
Using the four points around the drawing, we can see that angle four is connected to the vertex A.
The answer I believe is:
D. Vertex A.
Hope I could help! Have a good one.
<span>You need to look at the scale of different values and find one which is in the 40th percentile. This means 40 percent are higher and 60 percent are lower than the value you select. This can be done by figuring out the middle and going up a bit.</span>
