Answer:
0.41 × 570 = 5.7+228 = 234.
Step-by-step explanation:
If the 100 students are an accurate sample
(not a random sample, but chosen by first asking all 570 students the question and choosing 100 to reflect the proportion, and assuming they didn't change their answers and didn't lie)
then 41% of students have multiple pets so 0.41×570=234 have multiple pets.

Answer:
3.14
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
The constant of proportionality is the constant in this equation: π. To two decimal places, the value of π is 3.14.
The constant of proportionality is about 3.14.

Step-by-step explanation:
let width = w
if width = w, then length = w + 4
Therefore the perimeter is 2w + 2(w+4)
2w + 2(w+4) = 4w + 8
perimeter = 60cm
4w + 8 = 60
<em>-8</em>
4w = 52
<em>divide each side by 4</em>
w = 13
length = w+4
therefore, length = 17
