but we arent adults right!so it would be good if u dont be rude!

Until you suggested it, I did not think of it as rudeness. I suppose one’s mild impudence is another’s rudeness. How would you suggest, I gain the attention of someone in an environment of cacophony?

and for your hint, i cant find any use of it!it like a nursery school rhyme!

DS has one of the most advance computers in the world. It is not as advanced as yours, but it is close enough. DS can probably figure this out. There is a greater probability you can.

Remember, it is not just the nursery school rhyme, it is also the phrase that follows.

log(xy) = 14

log x + log y = 14

log x = 14 - log y

x = 10^(14 - log y).

What is submarine B's position?

Compute the parentheses first. Then, do the exponents. Finally, subtract.

If you enter, for example, 0.8 and hit enter, the calculator will display the fraction.

Use long division: 

Divide both sides by -3.

Then, add 8 to both sides.

Divide the number on the right side by 4 to get r.

(-3-3i)(-1-3i)

Use the FOIL method:

First, multiply the first terms: -3*-1.

Second, multiply the outside terms: -3*-3i.

Third, multiply the inside terms: -3i*-1.

Last, multiply the last terms: -3i*-3i.

Add all the results together and collect like terms. Remember i² = -1.

4%= .04. or 4 one hundreths.    .04 X  40000= 1600      15.8%= .158  or one hundred fifty eight thosandths.      .158 X  40000= 6320.    Since you are dealing with 40000 on both equations, you can add the %s together    (.04 + .158)=  .040 + .158=  .198 X 40000 =7920, the same as 1600 + 6320= 7920

25.5% of 2759

Convert the percent to a decimal by moving the decimal place 2 times to the left.

Finally, multiply the decimal with 2759.

You can use the on-site calculator to do this.

This doesn't make sense. How can x = something that has x.

If x = 1: 1 = (2+1)/1 ? NO & 1 = 2 + (1/1) ? NO.

Also, parentheses are very important! Is it (2+1)/x or 2+(1/x)?

Need parentheses for the n-2/3 part...could be (n-2)/3 or n - (2/3)...

Anyway, you can multiply both sides by 3 to get rid of the 1/3. From there, depending on where the parentheses go, you can solve the rest.

.5+.75=1.24= 17.5/14

You can use the on-site calculator to solve for this.

First, find the conversion of cg to g. You know that centi means 100, so how many grams?

.5 + .75= 1.25= 17.5/14

1.) Multiply both sides by 2.5 and add 62.5 to get x.

2.) Simply plug all the values into the formula for the z-score.

3.) The class has a total of 20+13+12+15 = ? students. What is 30% of ?. That is your answer. 

4.) 0.01 is the same as 1/100. 0.0062 is the same as 62/1000. Note that 4/99 is almost like 4/100. You should be able to figure out the order.

Add 8 to both sides and then divide that number by -15 to get m.

Distribute the 4.

Sorry, need to rework.

Make the square 1 m each side.  Area=  1X1=1 sq. m  Triangle is 18/3= 6m each side. Area of triangle = (6X6)/2=18   18plus 1= 19 sq.m

4. (there is always an invisible decimal after an integer).
