The scientific notation is .
Solution:
Let us first define the scientific notation.
Scientific notation is used to write large numbers in a small manner.
Rule to write the Scientific notation:
- Write one number before the decimal point.
- Count the zeroes and number after the decimal point.
For example:
500 can be written as 5 × 10².
6500 can be written as 6.5 × 10³.
Given data:
Distance from Earth to Moon = 221,000 miles
To write this in a scientific notation.
221,000 =
Hence the scientific notation is .
The answer is 71 when simplified
Cheese $1.99 * 1/2 = $1.00
Sliced Ham $3.29 * 3 = $9.87
Bread $1.59 * 2 = $3.18
Potato Chips $3 * 2 = $6
Salsa $1.39 * 1 = $1.39
Total $1.00+$9.87+$3.18+$6+$1.39
Total Spent $21.44
Coupon 1 $21.44-$4.00=$17.44
Coupon 2 $21.44 * 10% = $2.14
$21.44 - $2.14 =$19.30
Coupon 1 will save you the most money
Answer:
±3/5
Step-by-step explanation:
±sqrt(9/25)
We can separate this into
± sqrt(9) / sqrt(25)
Since these are perfect squares
±3/5
