Hey there, Guest!

Just as EP said, you might want to find the full word problem and double-check your grammar before posting.

Hey there, Guest!

Random question, this is from 8th-grade math ALEKS, right?

First, we need to find the area of the rectangle and then subtract the area of the circle from it.

1) \(35*19=630\)

2) \(A=(3.14)r^2\)

 \(A=3.14*81\)

\(A=254.34\)

3) 630-254.34

=\(375.66 cm^2\)

And there you have it, 375.66 cm^2 is your answer, mate. ;)

Hope this helped! :)

Hey there, Guest!

Alright, so I'll lead you step-by-step through this question.

Step 1: Simplify both sides of the equation.

\(3m^2+126=318\)

Step 2: Subtract 126 from both sides.

\(3m^2+126−126=318−126\)

\(3m^2=192\)

Step 3: Divide both sides by 3.

\(\frac{3m^2}{3}\)\(=\frac{192}{3}\)

\(m^2=64\)

Step 4: Take square root.

\(m=±√64\)

Therefore, m=8 when n=5.

Hope this helped! :)

Hey there, Guest!

So as we know, each dollar has 100 cents in it.

$6=600 cents

600/50=12

Therefore, Mrs. Smith bought 12 apples.

Hope this helped! :)

Hey there, Guest!

Alright, so AMber sold \(\frac{3}{4}\) of \(12\) candy bars on Saturday.

So we can turn that into an equation: \(\frac{3}{4}\)\(*12\)

Which equals 9.

12-9= 3

Therefore, she sold 3 candy bars on Wednesday.

Hope this helped! :)

Yeah, it should be "I am" or "I'm," but you'll get used to it. :P

Hey there, Guest!

So, the equation to find a circle's circumference is \(C=πd\).

So, let's insert the numbers now: \(C=π2\)

I know that IXL makes you use 3.14 for π, so the final equation should be 3.14*2.

And the answer to that should be 6.28.

And there, we have it, the answer.

Hope this helped! :)

Hey there, Guest!

As crazy as this might seem, this question is actually just division.

2625/25

See?

Now we need to solve it:

And then, BAM, there you have it, 25 is our answer.

Hope this helped! :)

Hey there, Guest!

Two equations can solve this problem for us here.

\(\frac{136}{4}=34\)

\(136 - 34 - 29 =\left [ 73\right ]\)

Therefore, 73 is our answer.

Hope this helped! :)

Hey there, Guest!

So this question has already been semi-answered here: https://web2.0calc.com/questions/dora.

Building off of what HighSchoolCalculus said...

We would burn the 5 hour one first with the 4-hour candle.

That would automatically give us 5 hours.

Then, when the first 4 hours are up, we would replace it with the 3-hour candle.

That gives us one more hour because of the limits of the 5-hour candle.

Now, do the addition:

5+1= 6 hours

Hope this helped! :)
