Question: solve for r: 6 ^ (2r) = 800
Answer: 1.87
Step-by-step explanation:
6 ^ (2r) = 800
log(6 ^ (2r)) = log(800)
2r log(6) = log(800)
r = log(800) / (2 log(6))
r = 1.86537641979
round
r = 1.87
log can be any logarithm function.
6^(2×1.86) = 784.734328546
6^(2×1.87) = 813.365367336
B. 0

Answer:
The amount of water in liters in 1/4 of the container.
Step-by-step explanation:
4 feet 8 inches
______________________________________________________________
First find how many inches are in 4 feet + 8 inches. There are 12 inches in 1 foot. Multiply 4 x 12 = 48. Add 8 to 48 = 56. Laney's height in inches is 56 inches.
______________________________________________________________
There are 2.54 centimeters in 1 inch. Multiply 56 x 2.54 = 142.24.
______________________________________________________________
Laney's height is 142.24 centimeters.
So eight (8) less than (3) times a number ( 8 - 3x) is (=) twice the sum of x (2x) and (4) so the answer would be 8 - 3x = 2x + 4
