We can use the compound interest formula
F=P(1+i)^n
where
F=Future value of investment to be found
P=present value of investment ($1000)
i=interest per period (1/4 year)=0.04/4=0.01
n=number of periods (3 years * 4 quarters = 12)
Substitute or "Plug in" values, so to speak,
F=1000*(1+0.01)^12
use a calculator to do the sum
=1126.83 (to the nearest cent, and use the proper rounding rules)
Answer:
Slove For X
x= -1
Solve for Y
Y= 10/3
Step-by-step explanation:
SO I did Elimination method
To isolate X and to solve for it
x+3y=9
3x−3y=−13
Add these equations to eliminate y:
4x=−4
Solve for X
x=-1
Now plug x back in to solve for y
Answer:
For blue its 3/12 = 1/4 = 25%
For red it's 6/12= 1/2= 50%
For green 2/12= 1/6= 17%
For black 1/12= 8%
Step-by-step explanation:
All you have to do is add up all the marbles 3 + 6 + 2 + 1 = 12 and then you put the number of marbles for each color and divide it by 12 which gives you those percentages. I don't know if you wanted the answers in percentages or fractions so I gave you both . Good luck!!
