Answer:

3x^3y^2\:+1\div 9y=3x^3y^2+\frac{1}{9}y

Step-by-step explanation:

Given the expression

3x^3y^2\:+1\div9y

According to the order of operation with respect to PEMDAS

  • Paretheses
  • Exponents
  • Multiplication
  • Division
  • Addition
  • Subtraction

so

  • 1 ÷ 9y is solved first

Thus, the expression becomes

3x^3y^2+\frac{1}{9}y

There are no like terms involved in the expression.

The expression is very much simplified.

Thus:

3x^3y^2\:+1\div 9y=3x^3y^2+\frac{1}{9}y

Mr. Ramsey just finished bathing his kids, and now he is draining the tub. The tub contains 32 gallons of water and is draining
KIM [24]
The answer would be 11 gallons.

The tub starts with 32 gallons. Every minute it loses 3 gallons.

So after 1 minute it has lost 3 gallons. For example:
32-3= 29 Meaning that after 1 minute the tub has 29 gallons left.

Now you have to remember that the tub is draining for 7 minutes. So it is losing 3 gallons 7 times, because it loses 3 gallons each minute and there are 7 minutes.

We can use multiplication to find how many gallons the tub loses after 7 minutes. This sign “X” basically means “groups of”. We have 7 groups of 3, or
7 X 3

This is the same as saying we have 3, 7 times. Written like this:

3+3 +3 +3 +3 +3 +3 = 21

So after 7 minutes the tub has lost 21 gallons.

Now we take the original number of gallons and take away what was lost:

32-21=11

So there are 11 gallons left after 7 minutes.

Please let me know if you need any further explanation. Hope this helped.

For a popular Broadway musical, the theater box office sold 356 tickets at $80 apiece, 275 tickets at $60 apiece, and 369 ticket
Stella [2.4K]
For 356 ticket, each ticket is $80, so all of those tickets cost 356 × 80 = $28,480.
For 275 ticket, each ticket is $60, so all of those tickets cost 275 × 60 = $16,500.
For 369 ticket, each ticket is $45, so all of those tickets cost 369 × 45 = $16,605.

For all of the tickets the box office took in you have to do:
28,480 + 16,500 + 16,605 = 61,585

<u>The answer is $61,585.</u>

The hypotenuse of a right triangle is 26 millimeters. One leg of the right triangle is 10 millimeters. What is the length of the
Daniel [21]
<span>Hypotenuse = 26 mm </span>

1st Leg        = 10 mm

Other Leg = x.

By Pythagoras Theorem:

x² + 10² = 26²

<span>x² + 100 = 676 </span>

x² = 676 - 100

x² = 576

x = √576

x = 24

<span>The other leg is 24 mm</span>
