Answer:

The hypotenuse of qrs is on triangle abc and triangle qrs are similar And have the same orientation.the hypotenuse of traingle Of Qrs Is on the same line as the hypotenuse of triangle Abc and is fourth times length of ab

i am not a expert i search it from web. if u feel its a right answer than only write.

Answer:

QR.

Step-by-step explanation:

A hypotenuse is an edge which is opposite to the right angle, or the longest edge of a right triangle.

Only right triangle has a hypotenuse.

Each right triangle has only one hypotenuse.

In this case, S is the right angle. The opposite edge is QR, so QR is the hypotenuse.

By Pythagoras theorem,

[tex]ac^{2} = {bc^{2} + ab^{2} } [/tex]

[tex]→13^{2} = {x^{2} + 12^{2} } [/tex]

[tex]→13^{2} = {x^{2} + 144} [/tex]

[tex]→169 = x^{2} + 144[/tex]

[tex]→169 - 144 = x^{2} [/tex]

[tex]→25 = x^{2} [/tex]

[tex]→ \sqrt{25} = x[/tex]

[tex]→5 = x[/tex]

Therefore, value of x is 5

Answer:

4/15  or 4:15

Step-by-step explanation:

We know a ratio is basically for everyone of this we will have a "x" number of the other for example

1:4 or 1:33

In order to solve this, all our data should be in the same unit

so in this case let's work with minutes

48min : 3hr  after converting 3hr to min we get...

48min : 180min

now we can simplify this to make this visually easier im going to use a fraction format

 48                    24                        12                 4

-------      ÷2     ----------     ÷2        --------     ÷3   -----   I can not simplify any further

180                   90                        45                15

So my answer is 4/15 or 4:15

Answer:

Identify h and k of [tex]y=a(x-h)^2+k[/tex]

Step-by-step explanation:

Hi there!

First, we would have to organize the quadratic function in vertex form:

[tex]y=a(x-h)^2+k[/tex]

a = vertical stretch

h = horizontal translation

k = vertical translation

If h is positive, the function moves to the right. If it is negative, the function moves to the left.

If k is positive, the function moves up. If it is negative, the function moves down.

I hope this helps!

Answer & Step-by-step explanation:

The equation that is often used for translations of quadratics is the vertex form:

y = a(x-h)^2 + k

This is for a parabola (the graph of a quadratic is a U-ish, V-ish curve called a parabola) that opens up or down. If you have a number inside the parenthesis with the x, such as (x+2) or (x-7) then the parabola will translate or slide left or right. If you alter the x, the curve gets moved in the x-direction left or right. This is the trickier translation bc its a bit backwards from what you expect. (x - 2) moves the curve 2 units to the RIGHT. (x + 7) moves the curve 7 units LEFT.

Then the vertical translations are the number tacked on the end in the vertex form of the equation. + 4 means translate(slide) the curve up 4 units. Whereas, a -3 at the end of the equation would slide the curve down 3 units.

So, for example

y = (x + 1)^2 + 5

The parabola would slide LEFT 1 and UP 5.

Using a system of equations, it is found that Carol is 10 years old.

The complete problem is:

"Gerrys age is 5 more than three times Carols age. If the sum of their age is 45, how old is carol?"

The variables are:

Gerry is 5 more than three times Carol's age, hence:

[tex]x = 5 + 3y[/tex]

The sum of their ages is 45, hence:

[tex]x + y = 45 \rightarrow x = 45 - y[/tex]

We then use the first equation to find Carol's age:

[tex]45 - y = 5 + 3y[/tex]

[tex]4y = 40[/tex]

[tex]y = \frac{40}{4}[/tex]

[tex]y = 10[/tex]

Carol is 10 years old.

Answer:

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan A = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{7}{8}[/tex] , then

∠ A = [tex]tan^{-1}[/tex] ([tex]\frac{7}{8}[/tex] ) ≈ 41° ( to the nearest degree )

The sum of the angles in the triangle = 180° , then

∠ B + 41° + 90° = 180°

∠ B + 131° = 180° ( subtract 131° from both sides )

∠ B = 49°

Using Pythagoras' identity in the right triangle

AB² = BC² + AC² = 7² + 8² = 49 + 64 = 113 ( take square root of both sides )

AB = [tex]\sqrt{113}[/tex] ≈ 10.6 ( to the nearest tenth )

missing number = 75

Step-by-step explanation:

% of 68 = 51

let the number be x

x% * 68 = 51

Answer:

Step-by-step explanation:

[tex]\frac{180}{t}[/tex] = [tex]\frac{75}{100}[/tex] ( divide numerator/ denominator by LCM of 25 )

[tex]\frac{180}{t}[/tex] = [tex]\frac{3}{4}[/tex] ( cross- multiply )

3t = 720 ( divide both sides by 3 )

t = 240

Answer:

So the way I'd do this is by figuring out the two missing rectangles, and then taking them away from the total area. The total area would be 10 × 12 = 120 inches, and the two rectangles would be 5 × 7 = 35, 35 × 2 = 70. Now, you just do 120 - 70 = 50 inches squared, which is your answer. I hope this helps!

Step-by-step explanation:

Trig property: if Sin A = Cos B,      Sin A = Sin (π/2 - B)

sin(6x-10) = cos(4x+10)

sin (6x-10) = sin (π/2 - (4x+10))

6x-10 = π/2 - (4x+10) + 2nπ

6x-10 = π/2 - 4x - 10 + 2nπ

10x = (1+4n)/2 * π

Answer:

y = -6x - 7

Step-by-step explanation:

We already know the slope so all we need to do is find th y-intercept. We can do this by using slope-intercept form and substituting the values we are given.

y = mx + b

5 = -6(-2) + b

5 = 12 + b

-7 = b

Put everything we know back into the formula.

y = -6x - 7

Best of luck!

Answer:

[tex]\displaystyle 6x + y = -7\:or\:y = -6x - 7[/tex]

Step-by-step explanation:

Plug the information into the Slope-Intercept Formula:

The slant height of a cone that has a lateral area of 320π cm² and diameter of 20 cm is 32 cm.

The lateral area of a cone can be described as follows:

where

r = radius

l = slant height

Therefore,

r = 20 / 2 = 10 cm

l = ?

lateral area = 320π cm²

320π = π × 10 × l

320π = 10πl

divide both sides by 10π

l = 320π / 10π

l = 32 cm
