The answer would be A)20/77.
The reason is that without replacement it would go (10/22)*(12/21)=0.2597
You can do the easy route I did then do (20/77) which would also give you 0.2597.

Yes, the bathroom have enough water and shampoo for 35 long haired and 40 short haired members.

<h3>What is inequality?</h3>

Inequality can be define as the relation of equation contains the symbol of ( ≤, ≥, <, >) instead of equal sign in an equation.

For 35 long haired and 40 short haired member.
Put this values in the given equation.

For water 70L+60S < 5600
  70 x 35 + 60 x 40
2450+2400
4850 <5600
inequality holds


For shampoo 0.02L+0.01S ≤ 1.50
0.02 x 35 + 0.01 x 40
0.7 + 0.4
1.1 < 1.50
inequality holds

Yeah i don't know how to answer this....
Deffense [45]

Answer:

y = \sqrt{16} x

that is equal to  y = 4x

\sqrt{16} = 4

when graphing (x,y) the x is the horizontal value of the point (east west)

and the y in the vertical (north south) ....

if you have y = x it would be a 45 degree line that goes from the lower left to the upper right....

if you compare the red line  the point  1,1  (y=x) versus 1,4 (y=4x) in the blue line you will see that it is "stretched" upward
