In how many different ways can the curator of a museum arrange five of eight paintings horizontally on the wall?

Help please asap I’m desperate!

Verizon [17]

Answer:

f(x)=x-2x+3; f(x)=-bx

x-2x=3=-bx

x+4x+3=0

(x+3) (x+1) = 0

x=-3 or x=-1

when x+-3. f(x)=b x(-3)=18

x=-1. f(x) = - b x (-1) = b

so system of equations : ( -3, -18)

; (-),b

Step-by-step explanation:

hope it helps

If 6 pipes fill a tank in 120 minutes, then 5 pipes can fill it in how many minutes

Marianna [84]

Answer:

It'll take 144 minutes for 5 pipes.

Step-by-step explanation:

${ \sf{6 \: pipes = 120 \: mins}} \\ { \sf{5 \: pipes = ( \frac{6}{5} \times 120) \: mins}} \\ \\ = { \sf{144 \: mins}}$

but practically, it seems to be abnormal. if 6 pipes take 120 mins, 5 pipes must takes a time greater than 120 mins cause amount of water flowing to the tank is decreasing.

But there is a possibility that pressure of water was increased for the case of five pipes, that's why it takes a time less than 120 mins. (t < 120)
