Answer:
B) 15
Step-by-step explanation:
sqrt(6x) = 3 sqrt(10)
Square each side
(sqrt(6x))^2 = (3 sqrt(10))^2
Remember (ab)^2 = a^2 b^2
6x = (3^2) sqrt(10))^2
6x = 9 * 10
6x = 90
Divide each side by 6
6x/6 = 90/6
x = 15
Divide 3.392 by 32 =.106 is the length because width X length = area
Answer:
Blake's car gets better mileage
Step-by-step explanation:
In order to find how many miles you get per gallon, you would do miles/gallons
As I'm typing this I realize it makes no sense but pretty much you just do 300/20 which is 15 mpg, and 495/15 which is 33 mpg, therefore Blake's car is better
To determine how much of the barrel is left to fill, you must subtract the amount of water already in it from the total mass of the bucket.
25.5 - 5.2 = 20.3 Litres
In order to the fill the entire barrel, Kelly must collect 20.3 Litres of water. You must then covert the measurement from litres to millilitres so that the bucket and barrel are measured in the same units.
20.3L = 20300mL
You must then divide the amount of space left by the mass of the bucket. This will determine the least number of buckets needed to fill the barrel.
20300 <span>÷ 800 = 25.375
That means the you would have to do a minimum on 25.375 buckets to fill the barrel, or 26.
Hope this helps :) </span>
