The length of the hypotenuse of a 45-45-90 Special Right Triangle is given by: Option C: 5√2 inches

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

For this case, we're specified that:

Thus, as shown in the diagram, the hypotenuse is AC.

Its length is found using the Pythagoras theorem as:

[tex]|AC|^2 = |AB|^2 + |BC|^2\\\\|AC|^2 = 5^2 + 5^2 = 25 + 25 = 50\\\\\text{Taking roots, but positive as AC is length, a non-negative quantity}\\\\|AC| = \sqrt{50} = \sqrt{25 \times 2} = \sqrt{5^2 \times 2} = 5\sqrt{2} \: \rm inches[/tex]

Thus, the length of the hypotenuse of a 45-45-90 Special Right Triangle is given by: Option C: 5√2 inches

Answer:

20%

Step-by-step explanation:

To do this we need to find the total number of marbles

272 + 68 ->  340

Now we divide 340 by 68 to get

68/ 340 = .2

Multiply by 100 because percent means PER 100 so to get this decimal in percent form multiply by 100

.2 * 100 = 20%

20% of Jodie's marbles are red

Answer:

im leaning on parallelogram

Step-by-step explanation:

Parallelogram, Quadrilateral, and Rectangles

First off both of these images are parallelogram because the arrows show that both the rectangle and the square (diamond/whatever you want to call it) have pairs of parallel sides so we know that both these shapes are parallelograms

Secondly, these shapes are both quadrilaterals. A quadrilateral, by definition, is simply a four-sided figure. Both a rectangle and a square are four-sided figures so these are both quadrilaterals.

Lastly, these figures are both rectangles. Yes I know one is a square and one is a rectangle but a square is a special four sided figure that can classify as a rectangle. Every square is a rectangle but not every rectangle is a square. A rectangle by definition is a four sided polygon with two pairs of parallel sides, congruent sides, and four 90 degree interior angles.

Answer:

v = 9

Step-by-step explanation:

6(v + 3) = 72

6v + 18 = 72

6v = 54

v = 9

Answer:

V = 9

Step-by-step explanation:

6(v + 3) = 72

Divide both sides by 6

6(v+3)/6 = 72/6

SImplify:

v + 3 =12

Subtract 3 from both sides:

v + 3 - 3 = 12 - 3

Simplify to get your answer of:

v = 9

Answer:

Tarea:

Ana compró una cartera cuyo precio es x dólares con el 10% de descuento y un perfume con precio original en dólares con un descuento del 15%. ¿Cuánto gastó Ana en total?

- Solución:

El precio estará en lenguaje algebraico, ya que no nos dan el dato de cuánto costó cada artículo.

• Hallamos el precio de la cartera con el descuento:

El precio original es x, entonces:

Regla de tres:

100 % --------> x

10 % -----------> ?

10 . x : 100 = ?

10x/100 = ?

El 10% del precio de la cartera es 10x/100.

Entonces el precio de la cartera es (x-10x/100).

• Hallamos el precio del perfume con el descuento:

El precio original es y, entonces:

Regla de tres:

100% -------> y

15 % --------> ?

15.y/100

El 15% del perfume es 15y/100.

Entonces el precio del perfume con el descuento es (y-15y/100).

Entonces lo que gastó en total es:

(x - 10x/100) + (y - 15y/100)

Step-by-step explanation:

Answer:

f(x) = 40 × (1.3)ˣ

Step-by-step explanation:

4. The given parameters of the population of mountain goats are;

The initial number of mountain goats, a = 40

The rate at which their population will increase, r = 30% = 0.3 exponentially

The total population after 'x' years is given by f(x)

For exponential growth, we have;

f(x) = a·(1 + r)ˣ

Plugging in the values, we get;

f(x) = 40 × (1 + 0.3)ˣ = 40 × (1.3)ˣ

Given:

A figure that contains a right triangular prism and cuboid.

To find:

The volume of the figure.

Solution:

The dimensions of cuboid are 16 in, 7 in and 3 in.

So, the volume of the cuboid is:

[tex]V_1=Length\times Width \times height[/tex]

[tex]V_1=16\times 7 \times 3[/tex]

[tex]V_1=336[/tex]

The base of the prism is a right angle with base 3 in and height 5 in, and the length of the prism is 6 in. So, the base are of the prism is

[tex]B=\dfrac{1}{2}\times Base\times Height[/tex]

[tex]B=\dfrac{1}{2}\times 3\times 5[/tex]

[tex]B=7.5[/tex]

The volume of a prism is:

[tex]V_2=Bh[/tex]

Where, B is the base area and h is the height of the prism.

[tex]V_2=(7.5)(6)[/tex]

[tex]V_2=45[/tex]

The volume of combined figure is:

[tex]V=V_1+V_2[/tex]

[tex]V=336+45[/tex]

[tex]V=381[/tex]

Therefore, the volume of the figure is 381 cubic in.

Answer:

r = 6 inch

Step-by-step explanation:

Given that,

The height of a cone, h =8 inches

The slant height of the cone, l = 10 inches

We need to find the radius of the base. The relation between height, radius and the slant height of the cone is given by :

[tex]r=\sqrt{l^2-h^2} \\\\r=\sqrt{10^2+8^2} \\\\r=6\ inch[/tex]

So, the radius of its base is equal to 6 inches.

Answer:

{ 3 }

Step-by-step explanation:

-30+9x=-0.5 |x-1| -2

from the graph, we can see that both curves intersect at (3,-3)⇒x=3

put x=3 in LHS&RHS

⇒LHS=-30+9(3)=-3

RHS=-0.5 |3-1|-2=

-1/2×2-2=-1-2=-3

so the answer will be 3..
