90
Step-by-step explanation:
300 / 30 which equals 90%
Answer:
Ok so 1. I am in AP Calculus BC and I legit just fully learned how to do exponents (I had a rough year in algebra 1 lol) so don't feel bad. And 2. It's really simple. When you multiply exponents you so just add them so x^2 * x^3=x^5. This makes sense visually since x^3 is x*x*x and x^2 is x*x and when you multiply that out you get x*x*x*x*x. Division is also pretty simple and all you have to do is subtract them. (There is a reason for this but its not important but I'll explain it anyways. Basically when you divide it is the same thing as multiplying by a negative exponent so x^3 / x^2 = x.) When you have multiple variables all you have to do is combine like terms so if you have something like xy^2*xy^4 you would get (x^2)(y^6). As for your problems, here:
8vx
63ce
21a^2
48xw^2
30m^3n^2
120a^2c^2x^3
2n
8x
3wx
4ac^2
2wx^2
2a^2c
5a
3
4c
8ab
7bc
8ac
I hope this helps!
(Also, double check those when you put them in please lol)
Answer:
bus is 8 books are 3 and apples are 2 so last answer should be 13
The radius of cone is 2 inches
<em><u>Solution:</u></em>
<em><u>The volume of cone is given by formula:</u></em>
![V = \frac{\pi r^2h}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B%5Cpi%20r%5E2h%7D%7B3%7D)
Where,
"V" is the volume of cone
"r" and "h" are the radius and height of cone respectively
Given that, volume of a cone is 16 pi cubic inches
Its height is 12 inches
Therefore, we get,
V =
cubic inches
h = 12 inches
r = ?
<em><u>Substituting the values in formula, we get</u></em>
![16 \pi = \frac{ \pi \times r^2 \times 12}{3}\\\\16 = 4r^2\\\\r^2 = 4\\\\r = \pm 2](https://tex.z-dn.net/?f=16%20%5Cpi%20%3D%20%5Cfrac%7B%20%5Cpi%20%5Ctimes%20r%5E2%20%5Ctimes%2012%7D%7B3%7D%5C%5C%5C%5C16%20%3D%204r%5E2%5C%5C%5C%5Cr%5E2%20%3D%204%5C%5C%5C%5Cr%20%3D%20%5Cpm%202)
Since, radius cannot be negative, ignore r = -2
Thus radius of cone is 2 inches
