# Decide whether the following rates are equivalent. 12 pages in 20 minutes or 20 pages in 32 minutes

QUESTION POSTED AT 20/02/2020 - 11:12 PM

The two fractions that we can extract from the given rates above are:
(1) 12 pages / 20 minutes
(2) 20 pages / 32 minutes
We can reduce the fractions or rates to their lowest term by dividing the numbers by 4 such that,
(1) 3 pages / 5 minutes
(2) 5 pages / 8 minutes
Therefore, the rates are not equivalent.

### Jonathan and Sarah purchased a beach house for $10,000,000. The home appreciates at a rate of 3% per year. The appreciation of the house is shown in the graph. The home is currently worth about$13,000,000. Jonathan and Sarah have owned the home for about ______ years. how many years

Current worth = 10,000,000 * (1.03)^years
We must determine the years when current worth = 13,000,000
13,000,000 / 10,000,000 = 1.03^years
1.3 = 1.03^years
Taking logs of both sides:
log (1.3) = years*log(1.03)
log(1.3) / log(1.03) = years
0.11394335231 / 0.012837224705 = years
years = 8.8760113598

### Which type of data is BEST described by a continuous model? A) points scored B) pages in a book C) children in a family D) temperature of an engine

The meaning of term continuous is that there should be no breaking.

In terms of mathematics , a function is said to be continuous function if there are no gaps when you plot the curve on coordinate axis.

In option 1, points scored is an incomplete statement.

Option 2, pages in a book is an example of constant function if you count pages between two pages. But it is a continuous function if page numbers are counted.

Option 3, children in a family is not a continuous function because there are gap in birth of two children.

Option 4, Temperature of an engine varies if engine is moving, otherwise remains constant.

Option (B), pages in a book is a type of data which is BEST described by a continuous model.

QUESTION POSTED AT 29/03/2020 - 04:30 PM

Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs, or 1.29x. This cannot be more than 20, so we set this less than or equal to 20: 1.29x ≤ 20. To solve this, we divide both sides by 1.29: ≤ ; x ≤15.5. We cannot download half of a song, so we round this down to 15 (although the number rounds up mathematically, he would not have enough money to download 16 songs). This means he can download at most 15 songs.

### Tristen is a salesman whose base pay plus commissions amounted to $59,238 last year. if his base pay was?$31,050 and he made \$97,200 in sales last year, what was his rate of commission? a) 61% b) 52% c) 29% d) 32%

The commission rate is 0.29 or 29%

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Before we can solve this problem, we need to create a formula that calculates the total amount of Tristen's payment. The formula would be the following,

Where:

• T is the total pay
• b is the base pay
• r is the rate of commission
• s is the total sales

Now that we have the formula we can plug in the values from the question and then solve for the rate of commission (r)

.... subtract 31,050 on both sides

.... divide both sides by 97,200

Now we can see that the commission rate is 0.29 or 29%

If so, we can write the following proportion:

AB/AC = BE/CD.
We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22
