Answer:
2/3
Step-by-step explanation:
If we divide both 8 and 12 by 4, we would get 2 and 3. 2/3
Answer:
n=7.87 years
Step-by-step explanation:
- The principal amount of $8000 doubles to become $16000.
-Given the rate is 9% compounded semi-annually, we first determine the effective rate:
We use this rate to in the compound interest formula to solve for n:
Hence, it takes 7.87 years for the amount to double to $16,000
Standard form
Coeficients are: a = 3; b = 4; c = 2;
Because
<span>is negative we get two </span>Complex<span> solutions;
</span>We can use the special Quadratic Formula
x = (-b + or - i
)/(2a); where i =
Then, x1 = (-4 + i2
;
In similar way, we obtain x2 = <span> (-2-i \sqrt{2} )/3;[/tex];</span>
Step-by-step explanation:
diameterfor first minute :
Circumference = 25.12
2πr = 25.12
22/7 × r = 25.12/2
r = 12.56 × 7 /22
r = 87.92/22
r = 3.99 mm ( approx. )
diameter = 2r = 2 × 3.99 = 7.98 mm
diameter for second minute =
circumference = 75.63
2πr = 75.63
πr = 75.63/2
r = 37.815 × 7/22
r = 264.705/22
r = 12.032 mm
diameter = 2r = 24.064 mm
<em><u>COMPARISON</u></em><em><u> </u></em>: 24.064/7.98
<u>3 times greater ( approximately )</u>
It is 56%. You divide 28 by 50 and get 0.56. then convert that into a percent and you find your answer which is 56%. :)
