Keisha drinks 15 quarts of water in 12 days what is the average amount of water that she drinks per day

Keisha drinks 1.25 quarts of water per day

Solution:

Given that,

Keisha drinks 15 quarts of water in 12 days

To find: Average amount of water that she drinks per day

Average amount of water that she drinks per day is found by dividing 15 quarts by 12 days

The formula used is:

Therefore,

Thus she drinks 1.25 quarts of water per day

the solution is h=10 because you add 9 to each side of the equation.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
