First, you are going to want to get the terms to the same power of 10 in scientific notation. Realize that
. Essentially, we have converted the
to a term with
. Now, we can subtract the values in each term that are not 10 as shown below:
![93 \cdot 10^6 - 3.14 \cdot 10^6](https://tex.z-dn.net/?f=93%20%5Ccdot%2010%5E6%20-%203.14%20%5Ccdot%2010%5E6)
![(93 - 3.14) \cdot 10^6](https://tex.z-dn.net/?f=%2893%20-%203.14%29%20%5Ccdot%2010%5E6)
![89.86 \cdot 10^6](https://tex.z-dn.net/?f=89.86%20%5Ccdot%2010%5E6)
Remember that we have to turn it back to scientific notation once we are done!
![89.86 \cdot 10^6 = 8.986 \cdot 10^7](https://tex.z-dn.net/?f=89.86%20%5Ccdot%2010%5E6%20%3D%208.986%20%5Ccdot%2010%5E7)
Our answer is the second choice,
. (This is the closest answer to
.)
A pair of jeans = $40.00
There is a 6.5% sales tax.
First change the % into a decimal by moving the decimal point two spaces to the left.
0.065
Multiply that by 40.00 to find out how much the tax is.
40 × 0.065 = 2.6
Now add the tax to the initial price.
40.00 + 2.6 = 42.60
The total cost is $42.60.
A.T.Q,
Birds = 120, Cats = 60, Dogs = 80
So, Cats : Dogs : Birds = 60 : 80 : 120 = 6:8:12 = 3:4:6
So, 3:4:6 is your answer.
Answer:

e number 45810 contains the combination "58"; the numbers 45180 and 48510 do not contain the combination "58" How many 5-digit numbers (between 10 000 and 100 000) contain the combination "58"?
Answer:
Mrs. Potts needs 72 feet of fencing.
Step-by-step explanation:
You find the perimeter of the rectangular garden, which is 24 yards. You then convert the yards to feet. There are 3 feet in a yard. You multiply 24 by 3 to get your final answer of 72 feet.
