Answer:
A) 9.56x10^38 ergs
B) 7.4x10^-3 mm
Step-by-step explanation:
A) 9.56x10^38 ergs B) 7.4x10^-3 mm A). For the sun, just multiply the power by time, so 3.9x10^33 erg/sec * 2.45x10^5 sec = 9.56x10^38 B) Of the two values 7.4x10^-3 and 7.4x10^3, the value 7.4x10^-3 is far more reasonable as a measurement for blood cell. Reason becomes quite evident if you take the 7.4x10^3 value and convert to a non-scientific notation value. Since the exponent is positive, shift the decimal point to the right. So 7.4x10^3 mm = 7400 mm, or in easier to understand terms, over 7 meters. That is way too large for a blood cell when you consider that you need a microscope to see one. Now the 7.4x10^-3 mm value converts to 0.0074 mm which is quite small and would a reasonable size for a blood cell.

5
Step-by-step explanation:
1. in order to calculate all the required values, it needed to solve:
2. x≥5 means, that x∈[5;+∞), where beginnig is '5'.
Hilda bought 15.11 lb of pork.
Step-by-step explanation:
Cost of Beef that Hilda bought = 4 17/20 = 4.85 lb
Cost of the total meat she bought = 19 24/25 = 19.96 lb.
To find the number of pounds of pork she bought, subtract.
Number of pounds of pork she bought = 19.96 - 4.85 = 15.11 lb.
