Answer:
$ 5674.076
Step-by-step explanation:
The question is on compound interest
The formulae = A= P(1+ r/n) ^nt .......where P is the principal amount, r is the rate of interest in decimal, n is number of compoundings per year and t is the total number of years.
Given; P= $4,000.00 , r=12/100=0.12, n=2 and t=3
Substituting values in the equation A= P(1+ r/n) ^nt
A= 4000 ( 1+0.12/2)^2×3
A=4000(1.06)^6
A=$ 5674.08
I don’t know the answer for a and b. I’m really sorry.
C) 24 more
D) 18 more hours
You need to know and have memorized metric unit conversions. They are easy, you just need to know how many zeros to add.
1 cm = 10 mm
1 m = 1000 mm
1 m = 100 cm
1 km = 1000 m
(1.) 4m + 3cm = 400cm + 3cm = 403cm
(2.) 3km + 8m = 3000m + 8m = 3008m
(3.) 7cm + 9mm = 70mm + 9mm = 79mm
(4.) 1m + 5cm = 100cm + 5cm = 105cm
(5.) 5km + 5m = 5000m + 5m = 5005m
Do you see that to switch 5km to smaller unit meters you just add the zeros on to the end. Because 1km = 1000m ; 5km = 5000m
You try the rest. let me know if you have any questions.
You cannot subtract a number from a unknown. You’d simply put (9-b) in its place.
<h3>I'll teach you how to solve 22/2 = x/3</h3>
--------------------------------------------------
22/2 = x/3
Switch sides:
x/3 = 22/2
Divide the numbers 22/2:
x/3 = 11
Multiply both sides by 3:
x/3*3= 11*3
Simplify:
x=33
Your Answer Is x= 33
plz mark me as brainliest :)
