Answer:

x = 8.57

Step-by-step explanation:

<em>Hi! So first of all, I attached an image that has my best visual explanation of how the 2 triangles overlap but are indeed two separate triangles! </em>

Since the question states that the triangles are similar, that basically means in simple terms that their sides are proportional or, are all based on the same fraction (proportion)! (An example of this is the triangles with the sides that correlate [in this problem, 11 to 7] would be 1 to 2, 3 to 6, and 4 to 8)

Now, we have to figure out which of our sides correspond, the first one being 11 to 7, and the second one being x + 15 (which I got by adding the small portion I have from the big triangle, and the portion I have from the smaller triangle together because the small triangle is inside of the big one!) to 15.

Next, I have to find out what x is based on the fraction (proportion) I already have which is 11 to 7 or \frac{11}{7}. Then, I compare this by setting this proportion equal to are other proportion with x in it!

\frac{11}{7} = \frac{x+15}{15}

Finally, I have to get x by itself to find what it is equal to, which you can see in the image! (If you have a number in the denominator and a variable in the numerator, and a regular number or fraction without a variable on the other side, you can just multiply both sides by the number in the denominator to cancel out the bottom of said variable fraction!)

<em>So! X is equal to 8.57!</em>

<em></em>

Hope this Helps! :)

Joeff charges 20$ flat rate plus 27$ per hour to work on cars. how many dollars does joeff earn for a 5 hour job?
Ket [755]
Answer is $155 for the job

Step by step

You can use y intercept formula for this one.

Y = mx + b
Y = Dollars earned, what you are looking for.
M= rate per hour (27)
X = hours worked (5)
B = flat rate (20)

y = (27) (5) + 20

y = $155

Problem solved!

Simplify.<br> (2x2 - 5x + 3) - (-x2 + 4x - 5)
vlada-n [284]

Answer:

Simplify.

(2x2 - 5x + 3) - (-x2 + 4x - 5)

the answer is -7x +12

Step-by-step explanation:

the question can be solved using BODMAS law

from Simplify.

(2x2 - 5x + 3) - (-x2 + 4x - 5)

opening the bracket

4-5x + 3 + 2x - 4x + 5

collecting the like terms we  have;

12-7x

therfore ; -7x  + 12

Question 4: Finding a basis of the orthogonal complement Consider the matrix Find a basis of the orthogonal complement of the co
pickupchik [31]

Answer: hello your question is poorly written hence I will provide the required matrix

answer :

A = \left[\begin{array}{ccc}1&0&1\\0&1&1\\1&-1&0\end{array}\right]

Step-by-step explanation:

Given that the basis of the orthogonal complement have been provided already by you in the question I will have to provide the Matrix

The required matrix

\left[\begin{array}{ccc}1&0&1\\0&1&1\\1&-1&0\end{array}\right]

column1 = column 3 - column2

where column 3 and column 2 are the basis of the orthogonal complement of the column space of the Matrix
