Because the ratio of women to children is 10:1, double the ratio of men to women so the women are both 10:
Men to women becomes 8:10
Now total the 3 ratios: 8 for men, 10, for women and 9 for children:
8 + 10 + 9 = 27
Divide total people by that number:
270/27 = 10
Multiply 10 by each ratio:
Men = 8 * 10 = 80
Women = 10 * 10 = 100
Children = 9 *10 = 90
There is 80 men.
Hello :
<span>(4-5i) +(-2+3i) -(1-7i) = (4-2-1)+(-5+3+7)i =1+5i....( answer : B)</span>
The manager’s likely error was forgetting to add the $2 back to the $18. Because $2 is roughly 11% of $18 for a markup you need to add the $2 back into the $18 for a total of $20.
1) To create an equation with r isolated, you divide both sides by π and square root both (it is given that all variables are positive). The equation is √A/π = r.
2) Plugging in the numbers give us <em>√54/(22/7) = r</em>.
√54(22/7) can be rewritten as √54*7/22, which is √378/22, which can be simplified to √189/11, or about 17.18.
Answer:
I'm pretty sure the answer is y=1x+3, also written as y=x+3
Step-by-step explanation:
the line crosses the y axis at 3, and the slope is 1 up and 1 over (1/1), simplified to just 1.
