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.)
X=side length
6x^2 = surface area = 150
x^2 = 150/6=25
x=sqrt(25)=5
Answer:
It means the factor that we multiply by itself three times to get that number.
Answer:
B)3x=15
Step-by-step explanation:
3x=15
x=15/3
x=5 (proven)
6 teaspoons
3/4 * 8 is 24/4
24/4= 6
So you need 6 teaspoons
