timurjin [86]

Answer:

<h3>"The answer is the yellow lines in the attached figure. </h3>

Step-by-step explanation: As shown in the attached figure, regular hexagon FGHIJK and square ABCD shares common centre on the co-ordinate plane and AB || FG.

We are to find the line across which the combined figure will reflect onto itself.

In the attached figure, we see two lines which are yellow in colour. We can easily detect that the figure will be reflected onto itself if these two lines acts as a mirror separately.

Hence these yellow lines are the required lines."

Ali picked three numbers out of a hat. Use the information in the box to work out what numbers he picked. The lowest number was
IgorC [24]

Answer:

The numbers he picked are 11, 17 and 24

Step-by-step explanation:

To solve this, we will work with the information we are given, interpreting it properly.

From the information given , we can already decode that the first of the three numbers is 11. We can write that number down.

The next piece of information we are given is that the range is 13.

The range of a data set is the difference between the highest and lowest numbers in the data set.

Let us say that our highest number is x

Range =x-11

x= range + 11\\x=13+11=24

Now, we know that the highest number of the data set is 24

Finally, from the information given, we can see that the median number is 17. This is the middle number of the data set. we can simply write that down since the number of figures in our data set is an odd number.

Hence the numbers picked are

11, 17 and 24 arranging them in an ascending order

Laura and Martin obtain a 30-year, $180,000 conventional mortgage at 10.0% on a house selling for $210,000. Their monthly mortga
Westkost [7]

Answer:

total payment = $563,760

Interest = $383,760

Principal part = $66

Step-by-step explanation:

(a) total payment:

n = 30 years = 360 months

monthly payment = $1,566

Total payment = $1,566 * 360 months = $563,760

(b) interest:

Total payment = $563,760

Principal = $180,000

Total payment = Principal + Interest

Interest = Total payment - Principal

Interest = $563,760 - $180,000 = $383,760

(c) part of first payment applied to the principal:

First payment = $1,566

Principal = $180,000

Interest rate = 10% yearly = 10% / 12 = 0.8333% = 0.008333 monthly

Monthly interest = Principal * Interest rate = $180,000 * 0.008333 = $1,500

Principal part = $1,566 - $1,500 = $66

Hope this helps!
