The volume of the rectangular prism is 4180in^3.

"A rectangular prism can be defined as a 3-dimensional solid shape which has six faces that are rectangles".

For the given situation,

Length of the rectangular prism = 19 in

Width of the rectangular prism = 20 in

Height of the rectangular prism = 11 in

The formula for volume of the rectangular prism,

[tex]V=l[/tex] × [tex]w[/tex] × [tex]h[/tex]

On substituting the values,

⇒[tex]V= 19[/tex] × [tex]20[/tex] × [tex]11[/tex]

⇒[tex]V=4180[/tex]

Thus the volume of the rectangular prism is [tex]4180 in^{3}[/tex].

The solution is : Second option is correct. O B. a circle, can not form a perpendicular bisector.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

here, we have,

Since we know that to form perpendicular bisector .

We need atleast two lines which form right angle.

So, right triangle can form perpendicular bisector with base and height.

Parallel lines can also form perpendicular bisector if a line is drawn from mid point of one line to mid point of another line.

A line segment can form perpendicular bisector.

But circle can't as it is curved shape it needs line to make perpendicular bisector.

Hence, Second option is correct. O B. a circle, can not form a perpendicular bisector.

Answer:

[tex]m(c(a)) = 4.8875a[/tex]

Step-by-step explanation:

The missing parameters are:

[tex]c(a) = 4.25a[/tex] --- Cost of marble countertops

[tex]m(c) = 1.15c[/tex] --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

[tex]c(a) = 4.25a[/tex]

[tex]m(c) = 1.15c[/tex]

[tex]m(c) = 1.15c[/tex] can be written as:

[tex]m(c(a)) = 1.15*c(a)[/tex]

Substitute: [tex]c(a) = 4.25a[/tex]

[tex]m(c(a)) = 1.15*4.25a[/tex]

[tex]m(c(a)) = 4.8875a[/tex]

Hence, the cost of marked up price is: [tex]m(c(a)) = 4.8875a[/tex]

Answer:

Step-by-step explanation:

The measure of the reference angle for a -287° angle is 17°.

To measure of the reference angle for a -287° angle

1. Determine the quadrant: First, we need to identify the quadrant in which the angle -287° lies.

  - In the standard coordinate plane, angles between 0° and 90° are in the first quadrant, between 90° and 180° are in the second quadrant, between 180° and 270° are in the third quadrant, and between 270° and 360° are in the fourth quadrant.

  - Since -287° falls in the third quadrant, we know that the reference angle will be found in the first quadrant.

2. Find the corresponding acute angle: To find the reference angle, we need to find the acute angle that has the same trigonometric values as the given angle.

  - To do this, we can add 360° to the given angle (-287° + 360° = 73°). This gives us an equivalent positive angle in the same position.

3. Determine the reference angle: Now that we have the positive equivalent angle (73°), we can find the reference angle by subtracting it from 90° (90° - 73° = 17°).

Therefore, the measure of the reference angle for a -287° angle is 17°.

Answer:

El pH del refresco es 3.42.

Step-by-step explanation:

Se puede calcular el pH del refresco usando la siguiente fórmula:

[tex]pH = -log([H^{+}])[/tex]

En donde:

[H⁺]: es la cocentración de los iones H⁺ de la solución

Entonces, el pH es:

[tex]pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42[/tex]

El resutlado obtenido nos permite concluir que ese refresco es ácido.

Por lo tanto, el pH del refresco es 3.42.

Espero que te sea de utilidad!

Usando su fórmula, se encuentra que el valor de PH de ese refresco​ es dado por 3.42.

[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]

Step-by-step explanation:

Since the hyperbola opens left and right with a center at the origin, then

[tex]\frac{x^{2} }{^{2} } - \frac{y^{2} }{b^{2} } = 1[/tex]

In the graph a = 60 and b = 11

So

[tex]\frac{x^{2} }{60^{2} } - \frac{y^{2} }{11^{2} } = 1[/tex].

[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]

Answer:

15

Step-by-step explanation:

The grade percentage of Marco is 50%.

A percent is a dimensionless number, meaning that it has no units of measurement, since it represents a part of whatever whole is being measured.

Given that, Marco got 15 questions wrong on his 30-question test.

We need to find his grade as a percent,

So,

Since he got 15 answers wrong,

Therefore, his correct answers = 30-15.

That mean his grade in marks = 15

Now, his grade in percent = 15/30 x 100 = 50%

Hence the grade percentage of Marco is 50%.

Answer:

125 units^3

Step-by-step explanation:

Volume is l*w*h = V. A cube has all equal sides so wecan divide 1000 by 3 and get our side lengths.

You then divide the sides by 2 because the question says the second cubes sides are half the size

5*5*5 = 125

The volume of the second cube is 125 units³.

In mathematics, ‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

Given that a cube has volume 1000 units³ and another smaller cube has smaller volume has side only half as long.

We need to find the volume of the second cube,

So, let the side of the first cube be x,

We know that the volume of a cube = side³

Therefore,

x³ = 1000

x = ∛1000

x = 10 units

Therefore, the second cube will have a side of 10/2 = 5 units

Volume of second cube = 5³ = 125 units³.

Hence the volume of the second cube is 125 units³.
