10. Given that N = 48 ÷ 3 × 2
⇒ N = 48 ÷ 3 × 2
⇒ N = 48 ÷ 6
⇒ N = 8
Answer:
Step-by-step explanation:
<u>Given ratio</u>
- 1/8 pound ⇔ 25 square feet
<u>To find </u>
<u>Divide both sides by 25</u>
- 1/8÷25 pounds ⇔ 25÷25 square feet
- 1/200 pounds ⇔ 1 square foot
The number 12,300 is written 1.23 x 10⁴ as a scientific notation. It's coefficient is 1.23; base is 10⁴ in exponent form.
Scientific notation is a method developed by scientists to shorten the number that expresses a very large number. The scientific notation is based on powers of the base number 10.
Scientific notation has two numbers: coefficient and base. The coefficient must be greater than or equal to 1 and less than 10. The base is always 10 written in exponent form.
12,300 as coefficient in standard form in scientific notation.
1) put decimal after the first digit and drop the zeros. from 12,300 to 1.23 this is the coefficient.
2) to find the exponent, count the number of places from decimal to the end of the number.
1.2300 ; there are 4 places
So the scientific notation is 1.23 x 10⁴
