Answer:
A
Step-by-step explanation:
In pattern A, we see that each number is 3 more than the one before it. B is incorrect because the pattern is +9. C is incorrect because the numbers in Pattern A is 3x Less than the corresponding numbers in Pattern B. D is incorrect because the numbers in Pattern B are 3x more than the numbers in Pattern A.
Hope this helps!
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.
S= d/t,
6.5mi/hr=d/30mi,
6.5mi/hr*30mi,
195mi=d.
I would say D. 10/16, 5/8

-- Kenny's weight is 6/7 of Melvin's weight.
-- Melvin's weight is 7/7 of Melvin's weight.
-- The ratio of Kenny's weight to Melvin's weight is (6/7) / (7/7) = 6/7 .
