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.

A pizza has a radius of 13.5 centimeters. What is the CIRCUMFERENCE of the pizza? Use 3.14 for pi. Round to the nearest tenth

Answers

Answer:

The circumference is:

[tex]C=84.8\: cm[/tex]

Step-by-step explanation:

The pizza is a circle, so the circumference equation is given by:

[tex]C=2\pi R[/tex]

Where:

R is the radius of the circumference.pi is 3.14

Therefore, the circumference is:

[tex]C=2\pi*13.5[/tex]

Quiz results:

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

What is Pythagoras Theorem?

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:

The triangle is 45-45-90 Special Right Triangle,that means, two of its angles are of 45 degrees and one is of 90 degrees.The legs of the triangle (non-slant side, the sides which are perpendicular to each other) are of 5 inches length.

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

4 A group of 40 mountain goats has just been
transplanted to an area with the expectation
their population will increase exponentially by
30% each year. If f(x) represents their total
population and x is the number of years in the
future, which function models the situation?

Answers

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

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

Answers

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)

If a cone has a height of 8 inches and a side measurement of 10 inches, what is the radius of its base?

Answers

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.

Jodie has 68 red marbles and 272 blue marbles. What percent of Jodie’s marbles are red?

Answers

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

To find:

increasing order of the given numbers.

Solution:

Increasing order: We need to start from the smallest number, then write larger number and end with the largest number.

We know that all negative numbers are less than the positive numbers and larger negative value is always the smaller one.

For example: -3 is less than -1.

i) We have,

3, -5, -2, 1

So, the increasing order of these number is -5, -3, -2, 1.

ii) We have,

-1, -8, -7, -2

So, the increasing order of these number is -8, -7, -2, -1.

iii) We have,

-2, -4, 0, 2

So, the increasing order of these number is -4, -2, 0, 2.
