The number of cans needed to paint an area covering 2,200 sq. units will be given by:
number of cans=[area required to be painted]/[area that 1 can of paint can cover]
=2200/400
=5.5
Therefore we conclude that we will need 5.5 cans of paint
10 times as much as 2000 is 1/10 of 200,000. I believe.
Should be A if I’m not mistaken
Answer:
A,shift the graph of y =x2 right 15 units
Step-by-step explanation:
You have to learn ho to translate some common words into algebraic expressions and equations.
Here are a few:
<u>"is" means "equals".</u>
When you see "is", write an 'equals sign. ( = ).
<u>"of" means "times".</u>
When you see "of", write 'times' or whatever symbol you like to use for it.
<u>"percent" or the symbol " % " means "divided by 100"</u>.
When you see (a number) with 'percent' or ' % ' after it,
write (the number) 'divided by 100'.
A <u>fraction-bar ( / )</u> and <u>'divided by'</u> mean the same thing.
When you see either one, you can always write the other one if you want to.
Examples:
' 1 divided by 2 ' means 1/2 .
47/54 means ' 47 divided by 54 '.
Now we're ready to look at the example in your question:
54 is 75% of (answer) .
Translation: 54 = 75/100 times (answer)
Now you have an equation. Go to work ! Manipulate it so that
you have (answer) on one side of the equation, and everything else
on the other side. You can do anything you want to one side of the
equation, but the rule is that whatever you do to one side, you must
immediately do exactly the same thing to the other side.
Here's how it works:
54 = 75/100 times (answer)
Multiply each side by 100 : 5400 = 75 times (answer)
Divide each side by 75 : 5400 / 75 = answer
Do the division for the fraction, and you have <em>72 = answer</em>
