The easiest way to solve this is to add 0.8 to 0.07 repeating 7 as fractions. 0.8 as a fraction is 8/10 and the other one as a fraction is 7/90. To give them a common denominator, 8/10 becomes 72/90. The two add to 79/90.
Answer:
$51.05
Step-by-step explanation:
In order to compare these, you would need to multiply the 5 gallon to match the 25 gallon. in which you would multiply by 5. because you multiplied the 5, you also need to multiply the 11. when you multiply 11 by 5 its 55. so your total comparison would be $55 for 25 gallons vs $51.05 for 25 gallons. Obviously the cheaper one is better.
Answer:
The average density of the rod is 1.11 kg/m
Step-by-step explanation:
Linear density is given by the expression 10/(sqrt(x 1)) kg/m
x is said to be measured in meters from one end of the rod. Therefore x represents the length of the rod = 8 m
Substitute the value of x into the expression of linear density to determine the average density of the rod
Average density = 10/(sqrt(81)) = 10/9 = 1.11 kg/m
