Answer:

Step-by-step explanation:

Using the Altitude- on- hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse), that is

x² = (30 - 6) × 30 = 24 × 30 = 720 ( take square root of both sides )

x = $\sqrt{720}$ = $\sqrt{144(5)}$ = $\sqrt{144}$ × $\sqrt{5}$ = 12 $\sqrt{5}$ → d

Answer:

$\frac{4x^2y-5xy^2-11}{y}$

Step-by-step explanation:

$\frac{8x^2y^2-10xy^3-22y}{2y^2}$

$=\frac{8x^2y-10xy^2-22y}{2y}$

$=\frac{4x^2y-5xy^2-11}{y}$

I need the answers for both a and b so thats why 61 points are up for grab

kodGreya [7K]

Answer:

Step-by-step explanation:

From the picture attached,

a). Triangle in the figure is ΔBCF

b). Since, $L_1$ and $L_2$ are the parallel lines and m is a transversal line,

m∠FBC = m∠BFG [Alternate interior angles]

Since, $L_1$ and $L_2$ are the parallel lines and n is a transversal line,

m∠BCF = m∠CFE [Alternate interior angles]

By triangle sum theorem in ΔBCF

m∠FBC + m∠BCF + m∠BFC = 180°

From the properties given above,

m∠BFG + m∠CFE + m∠BFC = 180°

m∠GFE = 180°

Therefore, angle GFE is the straight angle that will be useful in proving that the sum of the measures of the interior angles of the triangle is 180°.

How do you find which function has a greater rate of change?

sometimes the greater rate of change has a “steeper” slope or greater absolute value than the other function ...

A right cylinder has a radius of 6 m and a surface area of 84 m². Find the surface area of a similar cylinder with a radius of 2

dlinn [17]

Answer:

The surface area of the second cylinder is equal to $9.33\ m^{2}$

Step-by-step explanation:

we know that

If two figures are similar then

the ratio of their surfaces areas is equal to the scale factor squared

Let

z-------> the scale factor

x------> the surface area of the smaller cylinder (second cylinder)

y-------> the surface area of the original cylinder (first cylinder)

$z^{2}=\frac{x}{y}$

Step 1

Find the scale factor

$z=\frac{2}{6}=\frac{1}{3}$

Step 2

Find the surface area of the second cylinder

we have

$z=\frac{1}{3}$

$y=84\ m^{2}$

substitute and solve for x

$(\frac{1}{3})^{2}=\frac{x}{84}$

$x=\frac{1}{9}*84=9.33\ m^{2}$

Please someone help me

Marysya12 [62]

Answer:

The correct answer option is D. 5.

Step-by-step explanation:

We are given the following expression where 4 is to be divided by a fraction 1/5:

$4$ ÷ $\frac{1}{5}$

This can also be written as:

$\frac{4}{\frac{1}{5} }$

Now to find the quotient of this, we will take the reciprocal of the fraction in the denominator to change it into multiplication.

$4 \times \frac{5}{1}$

Therefore, ignoring the 1 in denominator, we can simply multiply 4 by 5.
