Answer:

Choice C is the answer.

Known information:

a = adult $

s = student $

We have 2 adults and 3 students.

Step-by-step explanation:

To find the total price of tickets given a # of students and adults, multiply a by the # of adults and multiply s by the # of students. Therefore, it would look like this:

2a + 3s = price

Therefore, choice C is the answer.

The area of this square

ANEK [815]

It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.

The area of a square is given by the equation $A=s^{2}$ where s is the length of the side.

$A=24^{2}$

A=576

The area of this square is 576cm2.

Hope this helps!

Ellen has a beginning balance of $370 in her checking account. She writes two checks for $40 and $50 respectively and deposits $

Naily [24]

$370.00 - $40.00 = $330.00
$330.00 - $50.00 = $280.00
$280.00 + $210.00 = $490.00
Ellen now has $490.00 as her new balance.

A coin is flipped until 3 heads in succession occur. list only those elements of the sample space that require 6 or less tosses.

Mashutka [201]

we are given

A coin is flipped until 3 heads in succession occur

so, firstly, we will find sample space

S={HHH , THHH , HTHHH, TTHHH , TTTHHH , HTTHHH , THTHHH , HHTHHHH, ......}

now, we are given that

list only those elements of the sample space that require 6 or less tosses

so, we can see that sample space

S={HHH , THHH , HTHHH, TTHHH , TTTHHH , HTTHHH , THTHHH , HHTHHHH, ......}

There are infinite such possibilities

so, there are infinite number of elements in space

and we know that

discrete sample space will always have finite elements

but we have infinite number of sample space elements here

so, this is not discrete sample space...........Answer

Someone please answer this correctly!!

Luda [366]

Answer:

1.98 × 10^10

Step-by-step explanation:

First solve for how many text messages were sent out per one month:

22,000,000 × 900

19,800,000,000

Convert into scientific notation:

1.98 × 10^10

In scientific notation, there can only be one number before the decimal. The rest of the numbers must be after the decimal; hence, why I put the numbers 9 and 8 after the decimal. If the rest of the numbers are zeros, you do not have to add them after the decimal. Instead, starting from right to left, count the number places until you reach your decimal. The number you have counted will be your exponent. I counted nine 0's, one 8, and one 9 which made this exponent 10 as there were 10 decimal placements.
