Answer: THE PROBABILITY OF DRAWING A YELLOW MARBLE IS 1/10

THE PROBABILITY OF DRAWING A RED MARBLE IS 5/18

Step-by-step explanation:

FIRST WE DIVIDE THE NUMBER OF YELLOW MARBLES  WITH THE TOTAL AMOUNT OF MARBLE THAT IS 2(THE NUMBER OF YELLOW MARBLES)/20(THE TOTAL NUMBER OF MARBLES IN THE BAG)

SO 2/20=1/10

WHEREAS IN THE SECOND ONE, THE YELLOW MARBLES ARE ALREADY DRAWN SO 20-2=18 5(THE NUMBER OF RED MARBLES)/18(THE TOTAL NUMBER OF MARBLES)

SO 5/18

What is the surface area of this<br> square pyramid?
Otrada [13]

Answer:

33 ft²

Step-by-step explanation:

The formula for the surface area of a square pyramid is:

SA = b² + 2bs

Where b is the measure of the base and s is the slant height

Let's substitute into this equation:

SA = b² + 2bs

SA = 3² + 2(3)(4)

Solve:

SA = 3² + 2(3)(4)

Square 3:

SA = 3² + 2(3)(4)

SA = 9 + 2(3)(4)

Multiply:

SA = 9 + 2(3)(4)

SA = 9 + (6)(4)

SA = 9 + 24

Add:

SA = 9 + 24

SA = 33

Therefore, the surface area is 33 square feet.

Accounts Payable had a normal starting balance of $800. There were debit postings of $600 and credit postings of $300 during the
sasho [114]
The normal balance of an accounts payable is credit.
So you start with $800-cr
Any debit posting will reduce that normal balance and any credit posting will increase the normal balance.


The $600 debit posting will create a $200 credit balance(800-600)


The $300 credit posting will create a $500 credit balance(300+200)

Answer: A. $500 - Credit.

It may help to figure it out if you create a t-chart and enter the amounts.

The equation y=1/9x relates proportional quantities x and y.
cluponka [151]

Answer:

x=36 when y=4

Step-by-step explanation:

When y=4, you have to multiply 1/9x by 9 to make x whole and to truly figure out how much it is worth. So if 1/9x =4, you need to multiply 4x9

4x9=36

x=36
