You use 6 6 gallons of water on 20 plants in your garden. At that rate, how much water will it take to water 30 plants?

1 answer:

5 0

So ask yourself how much would I use on 10 plants? Then take what your answer is and multiply that by 3. In this situation you would use 3 gallons of water on 10 plant. So that would mean that you would use 9 gallons of water on 30 plans. When I say this I'm assuming that you only need one of those sixes, and then the second six is a typo

20% of 50 is what number<br><br> PLEASE HELP

Oksanka [162]

To find a percentage, multiply the number by the percentage as a decimal. 20% as a decimal is .2.
50 times .2 is 10
50×.2=x
50×.2 = 10
10=10

20% of 50 is 10!

Break the number apart into hundreds, tens, ones, etc. and add the quantities together. Here is an example:

<em>To write 256 in expanded form, break it apart. There is 200, 50, and 6 in 250. Now, add them together. 200 + 50 + 6 = 256</em>

I need help with this asap

miss Akunina [59]

If Samuel can type 40 words per minute, he can type $40m$ words in $m$ minutes. So, the amount of minutes you're interested in is the solution of the equation

$40m = 3.5 \times 10^5 \iff m = \dfrac{3.5 \times 10^5}{40} = \dfrac{3.5 \times 10^5}{4\cdot 10} = \dfrac{3.5}{4} \times 10^4 = 0.875\times 10^4 = 8750$ minutes.

Since 8750/60 is 145 with reminder 50, Samuel can type the required amount of words in 145 hours and 50 minutes.

What are the values of A and B

Ostrovityanka [42]

Answer:

Step-by-step explanation:

Multiply the denominators so you will have common denominators.

Then 5x + 11 = A(x+3) + B(x+1)

So 5x + 11 = x(A+B) + 3A + B

The only thing that has x in right is (A+B)

So A+B = 5

And 3A + B = 11

So 2A=6

And A=3

B = 5 - 3 = 2
