NEED HELP PLEASE!!!!!!!!!!!!
Lostsunrise [7]

Answer: The exact answer is 3.61 weeks, so <u>the "about" answer is 4 weeks.</u>

Step-by-step explanation:

b = $85 + w (10+8)

b = 85 + w (18)

b = 85 + 18w

b is the total amount need in the bank account, so $150.

$150 = $85 + 18w

$150 - $85 = $85 - $85 + 18w

$65 = 18w

$65 / 18 = 18w / 18

3.611 weeks = w

So, it will take about <u>4 weeks</u> to get $150 in his bank account.

Hope this helps!

You have been assigned a 9 digit identification number.
aniked [119]

Answer:

1,000,000,000 identification numbers are possible.

Step-by-step explanation:

We are assigned a 9 digit identification number.

Each digit is a number from 0 to 9. So, each digit has 10 different choices.

Using the Fundamental Counting Principle (is better than the tree diagram) because it's simpler. To illustrate this, we can attempt to draw a tree diagram.

The first column will be the digits 0 to 9.

Then for each of those digits, we need another 0 to 9.

As you can imagine, the amount of numbers grow exponentially, so using the Fundamental Counting Principle is simpler.

And since we have a 9 digit identification number, with each digit having 10 choices, the total number of identification numbers possible are:

10\times 10\times 10 \times 10\times 10 \times 10 \times 10 \times 10 \time 10\times 10=10^9=100000000

So, 1,000,000,000 identification numbers are possible.

Suppose a triangle has sides a,b,and c and that a^2 + b^2
bagirrra123 [75]

Answer:

a^2+b^2=c^2

Step-by-step explanation:

a, b, c each represent a side. Lets say a triangle has a=2 and b=4.

  1. a^2= 2^2= 2*2= 4 do the same with B.

b^2= 4^2= 4*4= 16

    2. a^2+ b^2= 4+16= 20= c^2
