Answer:
500 flags each
Step-by-step explanation:
If 40 schools receive 250 each, then in total, that's 10,000
25,000 - 10,000 = 15,000. There are 30 schools remaining, so we divide. 15,000 / 30 = 500, so...
40 schools get 250 flags each, and the other 30 schools get 500 flags each.
600 ft³
Base area: B
Base is triangle
base = 12 ft and height = 5 ft
Area of triangle = B =
H = 20 ft
Volume = B * H
= 30 * 20
= 600 ft³
Just the second one is correct
Negative correlation
1 9/10
3 1/10 = 3.10
1 1/5 = 1.2
3.1 - 1.2 = 1.9
1.9 = 1 9/10
Hope this helped!
