Hi there
The formula of the future value of simple interest is
A=p (1+rt)
A future value?
P principle 750
R interest rate 0.09
T time 5years
So
A=750×(1+0.09×5)
A=1,087.5
Good luck!
Answer:
Below
Step-by-step explanation:
● x-20 = y+20 (1)
● 2(y-22) = x+22 (2)
This is a system of simulataneous equations
Let's simplify the expressions first
● x -20 = y + 20 (1)
Add 20 to both sides
● x -20 + 20 = y+20 +20
● x = y + 40 (1)
● 2(y-22) = x+22 (2)
● 2y - 44 = x +22
Substrat 22 from both sides
● 2y-44-22 = x+22-22
● 2y -66 = x (2)
This is the new system:
● x = y+40 (1)
● x = 2y-66 (2)
Substract (2) from (1)
● x-x = y+40-(2y-66)
● y+40-2y+66 = 0
● -y +106 = 0
● y = 106
Replace y with 106 in (1)
● x = y +40
● x = 106+40
● x = 146
So the solutions are (146,106)
0.765 (100) + .06 (.0765 x 100)
76.5 + .06 (76.5)
76.5 + 4.59 = 81.09 Chris will pay $81.09
Probability: Probability of an event to occur is given by:
Probability of Wednesday:
Probability of first day rainy:
Probability that first day is rainy Wednesday:
Let probability
Since these two events are independent
Percentage chances of rainy Wednesday
