Answer:
Step-by-step explanation:
1. 3.8 x 10^5 + 5.5 x 10^5 = 930,000 or 9.3 x 10^5
You just have to solve the equation and shorten the answer. For number one the answer is 930,000, so you have to make it into a number with decimals since a scientific notation number can not be equal to 10 or be greater. So you have to round the number to 9.3 not 93. To "round" it to 9.3 you have to move the decimal at the end of 930,000 to be in between the numbers 9 and 3. How many times you move the decimal to the left or right, that is the exponent of 10. So for 930,000 you moved the decimal 5 times to the left so the exponent for 10 is positive 5.
Answer:
1/6
Step-by-step explanation:

Answer:1.2 m/s
Step-by-step explanation:
Total distance covered is 500+500+200 m so the average velocity is given by
V = distance/time
V=1200/(17*60)
V=1.176 m/sec
57,800 is 23.8% of the total number of registered doctors.
To find out the number of registered doctors, we divide the number of female doctors by 23.8% as a decimal (which is just 0.238):
57,800 ÷ 0.238 = 242,857

Answer:
So there are 242,857 registered doctors.
