<h3>Answer: 36%</h3>
============================================
Explanation:
There are 20 blue cards out of 10+20+25 = 55 cards total.
Divide the 20 over 55 to get
20/55 = 0.363636...
where the "36"s go on forever
So 20/55 = 0.3636 approximately
Move the decimal point over 2 spots to go from 0.3637 to 36.37%
Then round to the nearest percent: 36.37% ---> 36%
The probability of getting a blue card is approximately 36%
Add 9 to both sides
x-9=0
x-9+9 = 0+9
x = 9
Answer- 971.76 yd^3 (btw I used pi not 3.14)
Explanation:
Solve for the volume of the cone
V=pi*r^2*h/3
V=pi*10^2*22/3
V= 2408.55
Next solve for the volume of the sphere
V=4/3*pi*r^3
V=4/3*pi*7^3
V=1436.76
The last step it to subtract the volume of the sphere from the volume of the cone
2408.55-1436.76=971.76
