Answer:
123,876.3 = 7 sig figs
1,236,840= 7 sig figs
422000 = 3 sig figs
0.000000000000211= 3 sig figs
0.000238 = 3 sig figs
0.0000205 = 3 sig figs
Step-by-step explanation:
Leading zeros are not significant, trailing zeros with no decimal are not significant. Whole numbers are always significant.
Here I'll Simplify it to show the work.
You need PEMDAS
9(2*2+4÷2)
9(4+4÷2)
9(8÷2)
9(4)
9(4) = 9 × 4 = 36
The Answer is 36.
250/5 = 50.....so each person is stacking 50 chairs...
50/20 = 2.5 minutes....so it takes each person 2.5 minutes to stack 50 chairs.
so ur answer is 2.5 minutes
Answer:
B) Victoria's method is linear because the number of minutes increased by an equal number every month.
Step-by-step explanation:
Zach reading time written in sequence form is given as:
- 10,20,40,80,...
- Each succeeding term is a product of the previous term by 2
Victoria reading time written in sequence form is given as
- Each succeeding term is an addition of 15 Minutes to the previous term.
The statement that best describes the methods used by Zach and Victoria to increase the time they spent reading a book is therefore:
B) Victoria's method is linear because the number of minutes increased by an equal number every month.
