Adog on intravenous fluids has received 40% of the 1000 ml initially in the i. v. bag. how many ml has it received?

Step-by-step explanation:

Givens

To know how many mL the dog received, we just need to find the 40% of 100 mL.

We know that 40% equals 0.40, then we multiply it

Therefore, the dog received 400mL

step-by-step explanation:

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.
