Please help me on this geometry question. Is it x axis tangent or y axis tangent?

Answer:

He should dial 289-743-1560

Step-by-step explanation:

The first three digits: "My first three digits are the square of an integer less than twenty"

Step 1: We can get the first three by looking at the squares of the integers from 1 to 19. We need a three digit number, so starting with 10, since 10² = 100, we list the squares of the integers from 10 to 19

10² = 100

11² = 121

12² = 144

13² = 169

14² = 196

15² = 225

16² = 256

17² = 289

18² = 324

19² = 361

Step 2: "The first three digits are in ascending order" and no digits can repeat, so we eliminate the answers above that don't satisfy both of these condintions. This leaves just 3 choices:

13² = 169

16² = 256

17² = 289

*We will come back to this once we have more information.

The last 2 numbers: "the last two digits are multiples of sixty".

The only 2 digit number that is a multiple of 60 is 60, so 6 and 0 are the last 2 digits. This rules out two answers from Step 1 since no digits can repeat. Only 289 works since 169 and 256 each have a 6 in them. So now we know the first 3, and last 2 numbers!

2 8 9 _ _ _ _ _ 6 0

The last 4 numbers: "the last 4 digits are multiples of sixty"

We want to find a 4 four digit number that has 60 as the last 2 digits. Notice a pattern when you multiply 60 by certain digits...

60 x 1 = 60

60 x 2 = 120

...

60 x 6 = 360

60 x 11 = 660

60 x 16 = 960 (these all don't work since they are not 4 digits)

60 x 21 = 1260 (this is the first 4 digit result, but it doesn't work because

there is a '2' in it, and 2 has already been used as the

first digit of the number)

60 x 26 = 1560 (this number could work, so lets try it and see if we can

satisfy the rest of the statements)

Now our number is

2 8 9 _ _ _ 1 5 6 0

The second three digits: "The second three digits are in descending order" and "The sum of the second three digits is 14"

If we assume that 1, 5, 6 and 0 are the last four digits, we know that 2, 8 and 9 are the first three digits, this leaves 3, 4 and 7 as the three remaining digits.

3 + 4 + 7 = 14 so that condition is satisfied. We just need to write then in descending order, so our final number is

289-743-1560

Answer:

the closet would have a width of 5 ft in real life. (5')

Step-by-step explanation:

When forming a blueprint, we often draw out / design the structure before building (so that we aren't just randomly building).

To do this, we are probably going to need to scale down the size of the measurements (scale down = make them each less at the same rate)

And, we usually need to include what the scale factor is (the amount that we are dividing/multiplying by to get from one size to another whilst staying at the same proportions).

If each inch on a map was ten miles, and you drew a 10 inch line, that would be representing a 100 mile line in real life.

1 : 10 = 10 : 100

$\frac{1}{10}=\frac{10}{100}$

(a scale factor of 10 is simple to work with logically. If the scale factor was a random number, like 7, finding equivalent ratios / fractions from dividing the original fraction to the value it is indicating. For example, if a map says 1 inch = 7 miles, I would know that whatever you have to multiply to get to 7 miles . There are 63,360 inches in a mile, so there are 443,520 inches in 7 miles. So, if I changed the area I am looking at to two inches, I must find how many inches would be in 2 x 7, [7+7] miles. The method that I found this value through is by finding how much I had to change the 1 to get to 2. I had to multiply the original value by 2, so I also must multiply the corresponding ratio by 2).

So, if 1 inch is equivalent to 10 feet (1" = 10'), and the width on the blueprint is 0.5 inches, we need to find how to get from 1 to 0.5.

(we divide by 2 ; 1 / 0.5 = 2 ; 0.5 x 2 = 1)

If we are dividing by 2 to find one half of the ratio, we will also need to divide by the same value to find the second half of a ratio.

10 ft / 2 = 5 ft

So, the closet would have a width of 5 ft in real life. (5')
