Answer:
The ratio is 
Step-by-step explanation:
The question in English is
In a group of high school third graders, 38 are right-handed and 6 are left-handed. find the ratio of right-handed to left-handed
Let
x -----> number of students that are right-handed
y -----> number of students that are left-handed
we know that
To find out the ratio of right-handed to left-handed, divide the number of students that are right-handed by the number of students that are left-handed
so
we have
substitute
Simplify
Anything greater than or equal to 6/15
$24
40 times 40% gets you 16.
Subtract 16 from 40 to get 24 which is your answer.
Answer:
4072
Step-by-step explanation:
I don't have any other loan terms to see, so i will assume that it's over a period of 10 years compounded at interest of 5%. If its not, you can just use the process I use to calculate the other loan terms cost.
So, you plug in the values. We know the final amount, A is equal to the original amount P, 2500, and the time is 10 years.
So A = 2500(1 + 0.05)^10 which equals 4072
Answer:
Call the number x and y. Then:
x - y = 45
and
x/y = 4, So x = 4y
Substitute 4y for x in the first equation:
4y - y = 45
3y = 45
y = 45/3 = 15
Substitute y = 15 in the first equation
x - 15 = 45
x = 45 + 15 = 60
So the two numbers are 60 and 15
