Answer:
- 152 men
- 76 women
- 38 children
Step-by-step explanation:
The ratios given are ...
men : women : children = 4 : 2 : 1
The total number of ratio units is 4+2+1 = 7, so each unit stands for 266/7 = 38 persons.
Then the numbers of each were ...
men : women : children = 4·38 : 2·38 : 1·38 = 152 : 76 : 38
There were 152 men, 76 women, and 38 children.
Answer:
Step-by-step explanatio
1mile = 5280 feet
607,200 / 5280 = 115
607,200 feet per hour = 115 miles per hourn
X² + 2x + 5 = 0
a = 1, b = 2, c = 5
Discriminant = b² - 4ac = <span> 2² - 4*1*5 = 4 - 20 = -16
Since the Disciminant, D < 0, the roots are imaginary</span>
