3:2=5
so girls are 2:5
set up the proportion
2/5=x/9
5x=18
x=3.6 girls; doesn’t work so no!

another way you can look at it is because there are 3 boys for every 2 girls, add 2 more girls, you’ll get 3 more boys
that makes the total of 10 people so 9 is impossible

Answer:

54.1%

Step-by-step explanation:

From the table, the total number of patients with type-B blood is given as 183. On the other hand, the number of males with type-B blood is given as 99. The percentage of patients with type-B blood who are males can be calculated as;

(the number of males with type-B blood/the total number of patients with type-B blood) * 100%;

( 99/183) * 100 = 54.1%

Therefore, the percentage of patients with type-B blood who are males is 54.1

nekit [7.7K]
$9,300
First, multiply your beginning amount by the percent of interest: 3,000x0.07 = 210
Then, multiply your interest times the number of years:
210x30 = 6,300
Add you interest to your initial amount:
3,000 + 6,300 = 9,300
