Answer:
70 m/s
Step-by-step explanation:
speed = √( g x depth ); where g = 9.8m/s²
given depth = 500m
equation becomes:
speed = √( g x depth )
= √( 9.8 x 500 )
= √( 9.8 x 500 )
=√4900
=70 m/s
Answer:
The straight time pay for $ 7.60 per hour and 40 work hours per week is $ 304.
Step-by-step explanation:
Let suppose that worker is suppose to work 8 hours per day, so that he must work 5 days weekly. The straight time is the suppose work time in a week, the pay is obtained after multiplying the hourly rate by the amount of hours per week. That is:
The straight time pay for $ 7.60 per hour and 40 work hours per week is $ 304.
Any transformation that is getting smaller is a dilation. Bigger, an enlargment. In this instance, it is a scale factor of 1/2, because scale factor 1 is congruent, greater than one an enlargement, less than one but greater than zero is a dilation.
Answer:
8-12a
Step-by-step explanation:
Answer:
11. B
12. D
Step-by-step explanation:
11)
2 times 10⁻² = 2·0.01 = 0.02 ≈ 0.0201
12)
6·10⁻⁴ = 6·0.0001 = 0.0006
However, 0.00058 rounds to 0.0006 and 0.00067 rounds to 0.0007, so the answer is a better estimation for D than for B.
