A used boat dealership buys a boat for $2990 and sells it for $4200. what is percent increase?

1 answer:

4 0

It is a 40.5% increase, how I got my answer.

It is really simple, all I done was added $2,990 and on a caculater started at 100% increase would be 5,980, the reason I started out with 100% is because it is much easyer to judge how much I need to go down or up in percentage, so I knew that I needed to find $4,200, so I moved it down to 45% which equaled $4,335.5 so I brought it down to 41% which equals $4,215.9, so I brought it down to 40% which equals $4,186, then I brought it up to 40.5% which equals $4,200.95, but the .95 does not matter.

I hope this helps!

Model the number 5.55 on the place value chart

Nady [450]

Answer:

Here's what I get

Step-by-step explanation:

Each digit in a number has a place value, based on its distance from the decimal point.

The value of a digit is the digit multiplied by its place value.

The place value of a digit increases by a factor of 10 as we move left on the place value chart and decreases by a factor of 10 as we move right.

Numbers to the left of the decimal point increase in the order: ones, tens, hundreds, thousands, etc.

Numbers to the right of the decimal point decrease in the order: tenths, hundredths, thousandths, etc.

So, we put the digits of 5.55 on the chart according to their place value.

A whole number from 1 to 15 inclusive is picked at random.

Helen [10]

Answer:

a) 3/7

b) 3/5

Explanation:

The figure attached shows the Venn diagram for the given sets.

a) What is the probability that the number chosen is a multiple of 3 given that it is a factor of 24?

From the whole numbers 1 to 15, the multiples of 3 that are factors of 24 are in the intersection of the two sets: 3, 6, and 12.

There are a total of 7 multiples of 24, from 1 to 15.

Then, there are 3 multiples of 3 out of 7 factors of 24, and the probability that the number chosen is a multiple of 3 given that is a factor of 24 is:

b) What is the probability that the number chosen is a factor of 24 given that it is a multiple of 3?

The factors of 24 that are multiples of 3 are, again, 3, 6, and 12. Thus, 3 numbers.

The multiples of 3 are 3, 6, 9, 12, and 15: 5 numbers.

Then, the probability that the number chosen is a factor of 24 given that is a multiple of 3 is:
