Answer:
8 helicopters at most
Step-by-step explanation:
I worked on this problem and that was the answer not 99 like the other.
Answer:
l=11.25 (total of both lengths, you divide that by 2 for one side.)
Step-by-step explanation:
l*w=20 ft
l=w+2 1/2 ft
w+2 1/2 *w= 20
-2 1/2
2w=17 1/2
divide by 2
w=8.75 l= 11.25
8.75+2.5 = 11.25
Answer:
<u>Let's verify is the corresponding sides have same ratio:</u>
- ΔABC, sides: 6, 9, 11
- ΔXYZ, sides: 21, 31.5, 38.5
<u>Ratios:</u>
- 6/21 = 2/7 (divide by 3)
- 9/31.5 = 2/ 7 (divide by 4.5)
- 11/38.5 = 2/7 (divide by 5.5)
The ratios are same, so the triangles <u>are similar</u>
- Yes, the sides are all proportional
The scale factor (ΔABC to ΔXYZ) is <u>2/7</u> (or ΔXYZ to ΔABC is 7/2 = <u>3.5</u>)
For this exercise it is important to know that, in Dilations:
1. When the scale factor is greater than 1, the Image (the figure obtained after the transformation) is an enlargement.
2. When the scale factor is greater than 0 but less than 1, the Image is a reduction:
And the scale factor is:
Since:
It is a reduction.
You can identify that the rule of this transformation is:
