<h2>Answer:</h2>

The percentage of loss is 43%.

<h2>Step-by-step explanation:</h2>

The first price was $210,000. He sold it for $120,000. First, we need to count how much money did he lost. We do it simply by 210,000-120,000 = 90 000. Then, we need to find out, what is 1% of the first price. We get it, If we divide 210,000/100 = $2100 Now, we divide the money he lost by one percent of the first price. 90,000/2100 = 42,85714 %. We round that to 43%. His percentage of loss is 43%.

I hope that I have helped you! I will be really happy, If you mark my answer as Brainliest.

Answer:

Bill suffered a loss of 42.85%.

Step-by-step explanation:

Bill bought a home for $210000 and sold it for $120000 and we have to calculate the percentage loss he suffered.

As we know loss suffered = Difference of sale price and cost price of the home.

Total loss = 210000-120000 = $90000

Now percentage loss = \frac{Total Loss }{cost price}.(100) = \frac{9000}{210000}.(100)

= 9/21×100 = 3×100/7 = 42.85%

So the answer is 42.85% loss.

Find the probability of a least one birthday match among a group of 44 people.
Cerrena [4.2K]

Answer:

0.1137= 11.37%

Step-by-step explanation:

Assuming there are 365 days in one year and every people have 1 birthday, then the chance for two people to have the same birthday is 1/365 and the chance they are not is 364/365. We are asked the chance for at least one match among 44 people. The opposite of the condition is that we have 0 matches and easier to calculate. The calculation will be:

P(X>=1)= ~P(X=0) = 1

P(X>=1)=- P(X=0)

P(X>=1)=1 - (364/365)^44

P(X>=1)=1- 0.8862

P(X>=1)=11.37%

What value of x will make ONM similar SRQ by the SAS similarity theorem?
Marta_Voda [28]

Answer:

The correct answer is 25

Step-by-step explanation:

See the attached figure.

SAS similarity theorem mean that when two triangles have corresponding angles are congruent and corresponding sides with identical ratios the triangles are similar.

So, if ΔONM similar ΔSRQ by the SAS similarity theorem

∴∠N = ∠R

And

\frac{NM}{RQ} =\frac{NO}{RS}

given that NM = 10 , NO = 8 , QR = x , RS = 20

∴\frac{10}{x} =\frac{8}{20}

∴x=\frac{10*20}{8} =25

So, the value of x will make ONM similar SRQ by the SAS similarity theorem = 25

Solve the system by using a matrix equation.<br> --4x - 5y = -5<br> -6x - 8y = -2
evablogger [386]

Answer:

Solution : (15, - 11)

Step-by-step explanation:

We want to solve this problem using a matrix, so it would be wise to apply Gaussian elimination. Doing so we can start by writing out the matrix of the coefficients, and the solutions ( - 5 and - 2 ) --- ( 1 )

\begin{bmatrix}-4&-5&|&-5\\ -6&-8&|&-2\end{bmatrix}

Now let's begin by canceling the leading coefficient in each row, reaching row echelon form, as we desire --- ( 2 )

Row Echelon Form :

\begin{pmatrix}1\:&\:\cdots \:&\:b\:\\ 0\:&\ddots \:&\:\vdots \\ 0\:&\:0\:&\:1\end{pmatrix}

Step # 1 : Swap the first and second matrix rows,

\begin{pmatrix}-6&-8&-2\\ -4&-5&-5\end{pmatrix}

Step # 2 : Cancel leading coefficient in row 2 through R_2\:\leftarrow \:R_2-\frac{2}{3}\cdot \:R_1,

\begin{pmatrix}-6&-8&-2\\ 0&\frac{1}{3}&-\frac{11}{3}\end{pmatrix}

Now we can continue canceling the leading coefficient in each row, and finally reach the following matrix.

\begin{bmatrix}1&0&|&15\\ 0&1&|&-11\end{bmatrix}

As you can see our solution is x = 15, y = - 11 or (15, - 11).
