Answer:
2.8
Step-by-step explanation:
You have to divide 0.42 by 15%.
0.42 / 15% = 2.8
Answer:
=12.56 ft^2
Step-by-step explanation:
First we need to find the radius
r = d/2 = 4/2 =2
Then we can find the area
A = pi r^2
= pi ^ 2^2
= 4pi
= 4*3.14
=12.56 ft^2
Answer:
Periodic Behavior consists of insects, like most other living organisms, exhibit cycles of activity that are synchronized with periodic events in their environment. Hatching, molting, foraging for food, courtship, and nest building are all examples of common behaviors that may recur at regular intervals.
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>)
