A cone is 1/3 the volume of a cylinder, so if the cone is 258.9, we should multiply by 3 is get the cylinder's volume:
258.9 times 3 = 776.7
Since no base is stated, assume base 10
remember
loga-logb=log(a/b)
also
![log_a(b)=c](https://tex.z-dn.net/?f=log_a%28b%29%3Dc)
translates to
![a^c=b](https://tex.z-dn.net/?f=a%5Ec%3Db)
and log(a^z)=zlog(a)
log25x-log5=2 means
![log_{10}(25x)-log_{10}(5)=2](https://tex.z-dn.net/?f=log_%7B10%7D%2825x%29-log_%7B10%7D%285%29%3D2)
translates to
![log_{10}( \frac{25x}{5} )=2](https://tex.z-dn.net/?f=log_%7B10%7D%28%20%5Cfrac%7B25x%7D%7B5%7D%20%29%3D2)
simplies to
![log_{10}(5x)=2](https://tex.z-dn.net/?f=log_%7B10%7D%285x%29%3D2)
translates to
![10^2=5x](https://tex.z-dn.net/?f=10%5E2%3D5x)
expands to
100=5x
divide both sides by 5
20=x
The answer should be the "Shawn" statement. Due to trying to find out the area, you would have to multiply length times width. so 14 x 35 = 490 ft^2 ( the up symbol is a karat, used to make it the exponent.) hope this helps!
3x-6y=-12 the answer is -4+2y but u didn’t say solve for what so I solved for x
-x+2y=8 the answer is y= 4+x/2 but u didn’t say solve for what so I solve for y this time
