Answer:
- 6.045×10^40 ergs
- 1.8×10^-2 mm
Step-by-step explanation:
A) Your scientific or graphing calculator can tell you the product:
(3.9×10^33 erg/s)(1.55×10^7 s) = 6.045×10^40 ergs
__
B) 10^2 mm is 100 mm, about 4 inches, so 1.8×10^2 mm is about 7 inches. This is somewhat larger than the diameter of a human hair (and about the same size as the diameter of a human <em>head</em>).
1.8×10^-2 mm = 18 μm is a more reasonable estimate of hair diameter
(The range of hair diameters is reportedly about 17 to 181 μm, so the given dimension is on the low end.)
125 is the answer.
A mean of vie numbers is 25. If it is 25, the numbers must be 25. So, since there is 5 of 25, multiply 25 by 5. Then, the answer would be 125.
There is also another way to do it. Set-up your equation.
x/5=25.
Now flip it to make the equation a multiplication problem.
25×5=x
Once you solve the equation, you should get 125 is the answer.
