F=5 dollar bills
t=twent dollar bills
38 total bills
f+t=38
400 in bills
400=5f+20t
we have
f+t=38
5f+20t=400
multipy first equation by -5 and add to second equation
-5f-5t=-190
5f+20t=400 +
0f+15t=210
15t=210
divide both sides by 15
t=14
subsitute
t+f=38
15+f=38
f=23
23 five dolar bills
15 twenty dollar bills
Circumference = 2πr
3π=2πr
r=3π÷2π
r=3/2
area of a circle= πr²
=π×(3/2)²
=2.25π
If you would like to know how much money you must save for an emergency fund of 6 months, you can calculate this using the following steps:
36% of $3,076.45 = 36% * 3,076.45 = 36/100 * 3,076.45 = $1,107.522
6 months * $1,107.522 = 6 * 1,107.522 = $6,645.132
The correct result would be $6,645.132.
75% because a third quartile is 3/4 which is 75% which if you break each fourth down it would be 25% so then you multiply 25%x3 to get 75%
