a hose fills a hot tub at a rate of 3.59 gallons per minute. how many hours will it take to fill a 309 gallon hot tub

iris [78.8K]

Answer:

about 1.43 hours.

Step-by-step explanation:

You can use your original equation to find how many minutes it takes to fill up the 309 gallon hot tub.

3.59x=309

x= how many minutes it takes to fill up a certain gallon.

Divide both sides by 3.59 to isolate x and you get x=86.0724234.

That is how many minutes it takes.

The question asks for how many hours, so that divide 86.0724234 by 60 since there are 60 minutes in an hour, and you get 1.43454039 or 1.43 hours.

There is also another way which is called dimensional analysis, but I don't know if you guys learned that yet.

Hope my answer helps!

20% of the rose Annette picked from a rose garden were red if she picked 10 red roses how many roses did she pick from the garde

horrorfan [7]

Answer:

Option A

Annette picked 50 roses from the garden

Step-by-step explanation:

Let us understand the problem, designating letters to represent unknown quantities.

Let the total number of roses = x

20% of the roses were red means that 20% of x = red

Since the number of red roses = 10,

we will have that 20% of x = 10

mathematically, we will have

$\frac{20}{100} \times x = 10\\x= \frac{1000}{20}= 50$

hence, Annette picked 50 roses from the garden

How do you reduce ln(3^-e e^3) to simplest form

leva [86]

The logarithm of a product is equal to the sum of logarithms:

$\ln(3^{-e}e^3)=\ln3^{-e}+\ln e^3$

Drop the exponents:

$-e\ln3+3\ln e$

The logarithm of a number is equal to 1 if the base of the logarithm is the same as the number itself:

$-e\ln3+3$
