I’m pretty sure the answer 30
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.
1.8 hours because 6 km is to 3 hours as 10 km is to x hours. So you multiply 3*6 and them divide it by 10
Area of 3400 decreases by 7.25%.
Rewrite 7.25% as a decimal.
This leads to 0.0725.
So, (3400)(0.0725) = 246.5.
Now (246.5)(13 years) = 3,276.
The area after 13 years will be
3,276 km^2.
If you take the square root of a number squared number then they cancel each other out and the number stays the same i.e. √[(4)^2] would equal 4.
In this problem the square root and numbered squared cancel out to leave the problem as -2a.
The solution of this problem is -2a
