Answer:

110 students

Step-by-step explanation:

Let the total money raised = R ($)

Let the number of student = x

Proposed ticket cost to activity night = $5

(a) R = 5x

     x = R/5----------------------------------------------- (1)

(b)  Total money to be raised to pay for rent  of $200 and have a left over of  $ 350 is = $(200 + 350)

            R    = $ 550

Substituting the value of R in equation (1), the number of student (x) can be found:

x = R/5

  = 550/5

 = 110 students

The student council must sell 110 tickets to students in order to achieve their goal.

A computer store changed the price of a laptop. It was originally $900, but now it is $1,100.Find the percent of change
tigry1 [53]

Answer:

The percent of change is 22.22%.

Step-by-step explanation:

You can calculate the percent of change by subtracting the original number from the final number and dividing that by the original number. Then, you have to multiply the result for 100:

percent of change=((1,100-900)/900)*100

percent of change=(200/900)*100

percent of change=22.22%

According to this, the answer is that the percent of change is 22.22%.

How should the decimal point in 34.05 be moved to determine the product 34.05×106 ?
r-ruslan [8.4K]

Answer: Six places to the right

Step-by-step explanation:

For this exercise it is important to remember that. by definition, the exponent of a number indicates the number of times you must use the same factor to multiply.

Given:

b^n

"b" is the base and "n" is the exponent.

In this case, you have the following multiplication provided in the exercise:

34.05*10^6

Notice that the base 10 has an exponent 6. This indicates the following:

10^6=10*10*10*10*10*10=1,000,000

By definition, moving the decimal point 6 places to the right (because there are six zeros), is the same as multiplying the decimal number 34.05 by 1,000,000.

  Therefore, based on the explained, when you move the decimal point six places to the right, you get the following product.

34.05*10^6=34,050,000
