Answer:
x=1
Step-by-step explanation:
3^ (3x+1) = 81
Rewrite 81 as a power of 3
3^4
3^ (3x+1) = 3^4
Since the bases are the same, the powers are the same
3x+1 =4
Subtract 1 from each side
3x+1-1 =4-1
3x=3
Divide by 3
3x/3 = 3/3
x =1
The volume is about 7234.56 cubic mm.
I assume the radius is 12 mm, it must have been repeated accidentally.
To find the volume of a sphere, we cube the radius, multiply by pi and finally multiply by 4/3.
We are the steps:
(12^3) = 1728 x pi (3.14) = 5425.92 x (4/3) = 7234.56
-17/2
Step-by-step explanation:
30-8(8)+4y
30=64+4y
30-64=4y
-34=4y
y= -34/4
y= -17/2

Hey there.
15% is equivalent to 0.15 and 1/8 is equivalent to 0.125. Let's set these from greatest to least:
0.2, 0.15 (15%), 0.125 (1/8), 0.09.
I hope this helps!
