It's 66 ft per second.
Answer:
Part A) Annual
Part B) Semiannual
Part C) Monthly
Part D) Daily
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
so
Part A) Annual
in this problem we have
substitute in the formula above
Part B) Semiannual
in this problem we have
substitute in the formula above
Part C) Monthly
in this problem we have
substitute in the formula above
Part D) Daily
in this problem we have
substitute in the formula above
Answer:
Step-by-step explanation:
Area of an equilateral triangle = 
Sub in your value of 16ft
A = 
A = 110.85 
Answer:
x=2, y=1
Step-by-step explanation:
2x + y = 5
5x − 2y = 8.
Multiply the first equation by 2
2( 2x + y) = 5*2
4x +2y = 10
Add this to the 2nd equation to eliminate y
4x+2y = 10
5x -2y = 8
--------------------
9x = 18
Divide by 9
9x/9 = 18/9
x = 2
Now find y
2x+y = 5
2(2)+y = 5
4+y = 5
Subtract 4 from each side
y = 5-4
y =1
Step-by-step explanation:
Let the number be x
160% of x=144

then we cross multiply


divide both sides by 160


therefore the number is 90
