Log3x - log13 = 2
This is to base 10, because the base was not specified.
log A - log B = log(A/B) law of logarithm
log(3x/13) = 2
By law of logarithm, conversion from logarithm to indices
(3x/13) = 10²
3x/13 = 100
3x = 100*13
x = 1300/3
x = 1300/3 = 433 1/3
Answer:
A.
Step-by-step explanation:
Answer:
320 ft^3
Step-by-step explanation:
I split the shape into 3 rectangular prisms. Two where 120ft^3 and one was 80 ft^3.
Adding them all together gave me 320ft^3. ( 80ft^3+ 120ft^3 + 120ft^3= 320ft^3)
Volume of drum = 3.14*r^2*h
= 3.14* 4^2 * 5 ( as r = 1/2*8 = 4 and h = 5)
= 251.2 ft^3
