First you need to find the amount of gallons per hour
1000 ÷ 4 = 250
then divide that by the amount of gallons you want to find (2500)
2500 ÷ 250 = 10
the answer is C. 10 hours

Answer:

Option C. 10\ hours

Step-by-step explanation:

we know that

A pipe can pump 1000 gallons of water in 4 hours

so

by proportion

Find how long would it take the pipe to fill a 2500 gallon pool

\frac{4}{1,000}\frac{hours}{gallons} =\frac{x}{2,500}\frac{hours}{gallons}\\ \\x=2,500*4/1,000\\ \\x=10\ hours

The transformation of a function may involve any change. The correct option is D.

<h3>How does the transformation of a function happen?</h3>

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

  • Left shift by c units, y=f(x+c) (same output, but c units earlier)
  • Right shift by c units, y=f(x-c)(same output, but c units late)

Vertical shift

  • Up by d units: y = f(x) + d
  • Down by d units: y = f(x) - d

Stretching:

  • Vertical stretch by a factor k: y = k \times f(x)
  • Horizontal stretch by a factor k: y = f(\dfrac{x}{k})

Given the function f(x)=2ˣ, while the h(x)=-3(2ˣ), therefore, the function f(x) is a reflection and a translation of a function. Hence, the correct option is D.

What is the answer meyn?
Alexandra [31]

Answer:

the best value is two 50 ml bottles

Step-by-step explanation:

Okay focus with me , if you buy a bottle of 50 ml you will get a second for half price so we can say that --> 2 bottles of 50 ml =

45 +  \frac{45}{2}  = 67.5

We get 100 ml with £67.5 just , but when you buy 80ml you must pay £55 Hum !

then you can dived the volume of bottle with price ...

  • the price of one ml is 0.675 in first State

\frac{67.5}{100 } = 0.675

  • in the second state the price of one ml is

\frac{55}{80}  = 0.6875

then :

0.675 < 0.6875

so the best value is two 50 ml bottles

Can anyone help with this?
Iteru [2.4K]

Answer:

It can not be proved, so the last option

Step-by-step explanation:

Because there are no two angles in one triangle so it's not AAS or ASA. And there are no two sides so it's not SAS either.
