Remember to incorporate Bimdas, into you calculation and ensure where the addition and subtraction occur you work from left to right.
Answer:
Im pretty sure A
Step-by-step explanation:
multiply both sides by 3/4 (reciprocal)
3/4X=pie(r)cubed
divide by pi on both sides
3/4X
-------- = r(cubed)
pi
cube root both sides
Answer: No, the money won't be enough to buy the car
Step-by-step explanation:
you plan on buying yourself a new $20,000 car on graduation day and graduation day is 24 months time. If you invest $300 a month for the next 24 months.
The principal amount, p = 300
He is earning 4% a month, it means that it was compounded once in four months. This also means that it was compounded quarterly. So
n = 4
The rate at which the principal was compounded is 4%. So
r = 4/100 = 0.04
It was compounded for a total of 24 months. This is equivalent to 2 years. So
n = 2
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount that would be compounded at the end of n years.
A = 300(1 + (0.04/4)/4)^4×2
A = 300(1 + 0.01)^8
A = 300(1.01)^8
A = $324.857
The total amount at the end of 24 months is below the cost of the car which is $20000. So he won't have enough money to buy the car
Answer: x = 4
Step-by-step explanation:
3x - 11 + 9 = 10
Add 11 to each side
3x + 9 = 21
Subtract 9 from each side
3x = 12
Divide each side by 3
x = 4
