Answer:

A pool can fill 22,000 gallons in 55 minute.

Step-by-step explanation:

Given :  A pool holds 22,000 gallons and to fill the pool at a rate of 400 gallons per minute,

To find  :  how long will it take to fill the pool .

Solution : We have given that

A pool can fill 400 gallons = 1 minute.

A pool can fill 1 gallons = \frac{1}{400}

A pool can fill 22,000 gallons =  \frac{22000}{400}.

A pool can fill 22,000 gallons = 55 minute.

Una ciudad tenía 8000 habitantes a final del año 2000. Cada año su población se incrementa en un 0.5 %
Digiron [165]

Answer:

The correct answer is 2030.

Step-by-step explanation:

To start we must analyze the information we have.

We know that a city has 8000 inhabitants and that each year this number increases by 0.5%. That means that <u>each year it has 40 more inhabitants</u>:

(8000 . 0,5) : 100 = 40

Having this information we could do a cross multiplication:

1 year ------- 40 inhabitants

x years ------- 81200

81200 = 40.x

x = 81200 : 40

x = 2030

In this way we can verify that the correct answer is 2030.

D is the wrong answer please help :(
Stella [2.4K]

This can be solved by Newton's binomial formula

Tk+1 = (n k) a∧(n-k) b∧k  k+1=7 => k=6, n=11 , a=-3x and b=-2y

T7= (11 6) (-3x)∧(11-6) (-2y)∧6 = (11*10*9*8*7)/(1*2*3*4*5) (-3x)∧5 (-2y)∧6

T7= 462 (-3x)∧5 (-2y)∧6

The correct answer is A.

Good luck!!!
