Hannah's school hosted a book donation. there are 150150 students at her school, and they donated a total of bb books! hannah donated 33 times as many as the average number of books each student donated. how many books did hannah donate? write your answer as an expression.

books.

Step-by-step explanation:  

We have been given that Hannah's school hosted a book donation.

Total number of students = 150.

Total number of books donated by all students = b.

Since we know that average is calculated by dividing the sum of the values in the set by their number.

Since we are told that Hannah donated 3 times as many as the average number of books each student donated.  So books donated by Hannah will be:

Upon simplifying we will get,

Therefore, Hannah donated books.

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!

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.
