Answer:

x = $\frac{C-By}{A}$

Step-by-step explanation:

Given

Ax + By = C ( subtract By from both sides )

Ax = C - By ( divide both sides by A )

x = $\frac{C-By}{A}$

Answer:

a. $\bold{45000\times \:10^7}$
b. $\bold{3500}$

Step-by-step explanation:

a. $\left(5\times \:10^3\right)\left(9\times \:10^7\right)$

$5\times 10^3 = 5000\\\\5000\times \:9\times \:10^7$

$\mathrm{Multiply\:the\:numbers:}\:5000\times \:9=45000$

$=45000\times \:10^7$

b. $\left(7\times 10^5\right)\div \left(2\times 10^2\right)$

$\left(7\times 10^5\right)\div \left(2\times 10^2\right)=\frac{7\times \:10^5}{2\times \:10^2}$

$\frac{10^5}{10^2} = 10^3$

$\frac{7\times \:10^3}{2}$

$\mathrm{Factor}\:\: 10^3 : 2^3\times5^3$

$\frac{7\times \:2^3\times \:5^3}{2}$

$\frac{2^3}{2}=2^2$

$7\times \:2^2\times \:5^3=3500$

Which triangles are similar by the angle-angle criterion for similarity of triangles ?

Alex Ar [27]

Answer:

Option D is correct.

$\triangle ADE \sim \triangle ABC$

Step-by-step explanation:

In triangle ADE and triangle ABC

From the figure:

$\angle ADE = \angle ABE$ [Angle] [Given]

$\angle DAE = \angle BAC$ [Angle]

AA(Angle-Angle) similarity criterion states that in two triangles if two pairs of corresponding angles are equal, then these triangle Similar.

By AA similarity:

⇒ $\triangle ADE \sim \triangle ABC$

Answer:

Mean= 4.9

Mean Absolute Deviation (MAD): 4.099173553719

Step-by-step explanation:

An outlier is a value that is very different from the other data in your data set. This can skew your results. As you can see, having outliers often has a significant effect on your mean and standard deviation. Because of this, we must take steps to remove outliers from our data sets.

outlier: 21
