First thing the formula is slightly mistated.
it should be
A=P(1+r/n)nt (you had rt fo the exponent and it should be nt
now lets solve this thing
you want A = 2P (double your money
2P = P(1+r/n)nt
we can divide through by P adn put in the values we know
2 = (1+.085/2)2t
2 = (1.0425)2t
and now we can take the log of both sides to make it easy to solve our equation
log(2) = 2tlog(1.0425)
.301 = 2t (.018)
divide both sides by .018
16.653 = 2t
t = 8.327 (number of years to double your money at this rate
check it
(1.0425)16.653 =2
Answer:
30 is the correct choice.
Step-by-step explanation:
150 = {baseball} + {cricket} + {soccer} - {exactly 2 sports} - 2*{exactly 3 sports} + {none of the ports}
150 = 66 + 45 + 42 - 27 - 2*3 + {none of the ports}
--> {none of the ports} = 30

Answer:
Step-by-step explanation:
∠CGH = 14° {Vertical angles are congruent}
∠EGH = ∠EGC + ∠CGH
= 78 + 14
= 92
GH // EC and BG is transversal.
∠BEC = ∠EGH {Corresponding angles are congruent}
4x = 92
Divide both sides by 4
x = 92/4
x = 23°
Step-by-step explanation:
x(x+2)-6(x+2)
x^2+2x-6x-12
x^2-4x-12
Answer:
Step-by-step explanation:
step 1
Find the perimeter of one lap
we know that
The perimeter of one lap is equal to the circumference of a complete circle (two half circles is equal to one circle) plus two times the length of 96 meters
so
we have
substitute
step 2
Find the total meters of four laps
Multiply the perimeter of one lap by four
