In a recent year, 22.8% of all registered doctors were female. if there were 49,900 female registered doctors that year,

what was the total number of registered doctors?

round your answer to the nearest whole number.

oc

218,860

Step-by-step explanation:

If you were to set up a proportion, you would set it up as 22.8/100 = 49,900/x. Then you would cross multiply the numbers to get that 22.8x = 4,990,000. Then you would divide 4,990,000 by 22.8 and get 21859.649122807. You want a whole number so the .6 would round the 9 up and you would get 218,860.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
