Dr. Al-Islam teaches the football team 4 new plays in 2/5 of a practice. How many new plays can he teach them in one practice?

1 answer:

4 0

10 plays

Divide 2/5 and 4 by 2 to get 1/5 and 2

For every 1/5 of practice he teaches the ten 2 plays

5/5 = 1

So 5*2 = 10 plays

$\bf f=k\sqrt{t}\quad \textit{we also know that }

\\\\\\
\cfrac{300}{\sqrt{8}}=k\implies \cfrac{300}{\sqrt{2^2\cdot 2}}=k\implies \cfrac{300}{2\sqrt{2}}=k\implies \cfrac{150}{\sqrt{2}}=k

telo118 [61]

Area of the garden that 15 trees are planted will be:
Area=250×25=6250 ft²
but 1 acre= 43560 ft²
thus converting our area to acres we get:
6250/(43560)
=0.1435 acres
thus the population density will be:
(Population)/(area)
=15/0.1435
=104.544 trees/acre

15/x = 20/100
15*100 = 20*x
1500 = 20x

75 = x

15/75 = 20/100

the expected number of couples who met online is 75
