Neither because they are different size and mirrored it could’ve been congruent but it’s double the size and congruent is mirrored and the same size

You rent an apartment that costs $1100 per month during the first year, but the rent is set to go up 9.5% per year. What would b

uranmaximum [27]

Answer:

$2076.30

Step-by-step explanation:

In the n-th year, the rent will be ...

an = a1·r^(n-1) . . . . . . . . . r is the year on year ratio: 1+rate of increase

an = 1100·(1.095^(n-1))

Then the rent in the 8th year is ...

a8 = 1100·(1.095^(8-1)) ≈ 2076.30

The rent in the 8th year would be $2076.30.

the sum of the digits of two digit number is 10. when 18 is added to the number is digit reversed find and number

Contact [7]

Answer:

<em>The number is 46</em>

Step-by-step explanation:

<u>Equations</u>

Suppose:

a = One digit of the number

b = Tens digit of the number

The sum of the digits is 10:

a + b = 10

The number expressed as two-digits quantity is ab, and its value is

10a+b

When we add 18 to that number, we have:

10a+b+18

And that is represented as the number reversed:

10a+b+18=10b+a

Simplifying:

9a+18=9b

Dividing by 9:

a + 2 = b

Substituting in the first equation:

a + a + 2 = 10

2a = 8

a = 4

b = a + 2 = 6

Thus the number is 46

What are the values the values of a and b?

Setler [38]

The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

$\frac{20}{a} = \frac{21}{20}$

Solving,

$21a =(20)(20) \\ 21a = 400 \\ a = \frac{400}{21}$

To find b, use the fact that b is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it, a.

$\frac{b}{a} = \frac{21+a}{b}$

A little arithmetic shows that $21+a = \frac{841}{21}$ .

$\frac{b}{\frac{400}{21}} = \frac{\frac{841}{21}}{b} \\ b^2 = \frac{336400}{441} \\ b=\frac{580}{21}$
