Mike drew p pictures. Rick drew 41 fewer pictures than Mike. Choose the expression that shows how many pictures Rick drew. (A.) p

(B.) 41 + p

(C.) p - 41

(D.) 41 - p

It's p - 41.

Step-by-step explanation:

We're trying to find how many pictures Rick drew, which is 41 less than how many Mike drew, p. To find the expression in situations like these, always take how many fewer was drawn from the amount the other person drew, which would be 41 - p. But this would most likely give us a negative answer, which isn't possible. Switch them around and you have p - 41.

the answer is c)8

step-by-step explanaction:

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.
