Answer:

12.5 gallons

Step-by-step explanation:

Make a proportion

50 gallons of water in 20 minutes, and x gallons of water in 5 minues

50/20=x/5

To solve, we need to get the variable, x, by itself. Right now, it is being divided by 5. To get rid of this, multiply both sides of the equation by 5

5(50/20)=(x/5)5

This will allow the 5s on the right to cancel, leaving us with

12.5=x

A city has a population of 240,000 people. Suppose that each year the population grows by 7.75%. What will the population be aft
emmasim [6.3K]

Answer:

\large\boxed{\sf \ \ \   404,699 \ \ \ }

Step-by-step explanation:

Hello,

At the beginning the population is 240,000

After 1 year the population will be

   240,000*(1+7.75%)=240,000*1.0775

After n years the population will be

   240,000\cdot1.0775^n

So after 7 years the population will be

   240,000\cdot1.0775^7=404699.058...

So rounded to the nearest whole number gives 404,699

Hope this helps

How do I get the answer??
Lubov Fominskaja [6]

Answer:

4√10

Step-by-step explanation:

Hello!

Let's first simplify the radical.

We can do this by expanding the radical:

We need to pull out a perfect square factor to expand a radical and simplify it. In 45, we have 9 and 5 multiplied, and 9 is a perfect square.

Let's work with √45:

  • √45 can be written as √9 * √5 (using the rule √ab = √a * √b)
  • √9 simplifies to 3, so it is 3√5

Now we can simplify the operation in the parenthesis by combining like terms:

  • 3√5 + √5
  • √5 + √5 + √5 + √5
  • 4√5

Now using the same rule as above, we can multiply the values:

  • √2(4√5)
  • 4√10

Your solution is 4√10
