Answer:20 is the least common
Step-by-step explanation:
Answer:
D) 70 ft
Step-by-step explanation:
1 inch = 20 feet
3 1/2 inches= 20 feet*3 1/2 inches
= 70 ft
ANSWER: 40
EXPLANATION:
1) 40.73 to 1 significant figure = 40.
2) 1.06 to 1 significant figure = 1.
3) Therefore, we just multiply 40 by 1, which equals 40.
FURTHER EXPLANATION (IF NEEDED):
With significant figures, whole numbers such as 10, 20, 50 etc. have 1 significant figure. This is because the 0 does not count as a significant figure.
With decimals, all numbers after the decimal point are also included as significant figures (even 0). E.g. 40.73 has 4 significant figures and 1.06 has 3 significant figures.
EXAMPLES (IF NEEDED):
Rounding to 2 significant figures:
Rounding to 3 significant figures:
- 40.73 = 40.7
- 1.06 = 1.06 (because it's already in 3 significant figures)
Rounding to 4 significant figures:
- 40.73 = 40.73 (already in 4 significant figures)
- 1.06 = 1.060 (0 is counted as a significant figure if there is a decimal or another number comes after that 0)
E.g. 1006 has 4 sig figs, while 1060 would have 3 sig figs because the last 0 is not counted as a significant figure. 10.60 would have 4 sig figs because of the decimal.
3323.5 because if you times the number left by the 15 percent this is the answer.
The absolute value of a number is how many digits away from zero it is, the actual value includes negative numbers while absolute value numbers do not include negatives
hope this helps!
