When John bought his new computer, he purchased an online computer help service. The help service has a yearly fee of $25.50 and

a S10.50 charge for each help session a person uses. If John can only spend S170 for computer help this year, what is the maximum number of help sessions he can use this year?

The yearly fee can be subtracted, resulting in 170-25.50=144.5

So with 10.50 a session, you must divide, resulting in around 13.8 sessions.

13 sessions if you need a whole number.

Hope this helps

Which choice below shows the following numbers in order from least to greatest?
vfiekz [6]

Answer:

1/3, \sqrt{4}, π, \sqrt{16}, 8

Step-by-step explanation:

Simplifying or rounding complicated numbers to integers can help us order them.

  • Integer - an integer is any whole number, including zero, that can be negative or positive.

Simplifying Numbers

Numbers like 1/3 and 8 don't need to be simplified because they are commonly used and understood.

Both 4 and 16 are perfect squares. So, to simplify these numbers we can just solve.

  • \sqrt{4} = 2
  • \sqrt{16} = 4

There is no way to "solve" pi, but we can round it to an easier number. Technically, pi is irrational, so there is no way to write out the whole number. However, in this case, we can just round to the nearest whole number.

  • π ≈ 3

This means, in the order they appear, the simplified numbers are 2, 8, 4, 1/3, and 3.

Ordering the Numbers

From this point, they should be easy to order.

  • 1/3 is the smallest because it is the only number less than 1.
  • \sqrt{4} is next because it is equal to 2
  • π is third since it is only slightly above 3
  • \sqrt{16} is fourth since it is equal to 4
  • 8 is the largest number on the list.

Gas mileage is the number of miles you can drive on a gallon of gasoline. A test of a new car results in 440 miles on 20 gallons
Mamont248 [21]

Answer:

Step-by-step explanation:

20 : 440 = 60:x

Product of means = 440*60

Product of extremes = 20*x

20*x = 440*60

x = 440*60/20 = 440*3

x = 1320 miles

james has $3000 in credit card debt, which charges 14% interest. how long will it take to pay off the card if he makes the minim
GREYUIT [131]

Answer:

The answer is approx 75 months.

Step-by-step explanation:

We have P = 3000

r = 14%

Monthly payment = $60

We will use the formula :

[(0.14/12) \times3000] / [1- (1+(0.14/12)^{-12n}]

Solving this we get n = approx 75 months. After 75 months few dollars will be left. And in the 76th month the balance will become negative.

For easy and better understanding, I have attached an excel sheet.

The answer is approx 75 months.
