Un prisma cuadrangular regular tiene 4 m de arista de la base y 6m de altura Calcula el area y el volumen
Answers
Answer:
El área y volumen del prisma cuadrangular mencionado son respectivamente:
Área = [tex]16m^{2}[/tex] Volumen = [tex]96m^{3}[/tex]Step-by-step explanation:
Para solucionar este ejercicio debes recordar que un prisma cuadrangular tiene como base y como superficie cuadrados, por lo tanto, para calcular el área de dicho cuadrado puedes utilizar la siguiente fórmula:
Área de un cuadrado = [tex]arista^{2}[/tex]Ya que el ejercicio nos da el valor de la arista (4 metros), podemos reemplazarla en la ecuación y calcular:
Área de un cuadrado = [tex](4m)^{2}[/tex]Área de un cuadrado = [tex]16m^{2}[/tex]Por último, para calcular el volumen debes multiplicar el área superficial, el área del cuadrado calculado, por la altura del prisma, cuyo valor dentro del enunciado es de 6 metros, de esta forma:
Volumen de un prisma cuadrangular = área superficial * alturaVolumen de un prisma cuadrangular = [tex]16m^{2}[/tex] * [tex]6 m[/tex]Volumen de un prisma cuadrangular = [tex]96m^{3}[/tex]Como puedes ver tras los cálculos, el área superficial del prisma es de [tex]16m^{2}[/tex] y su volumen es [tex]96m^{3}[/tex].

Just subtract 16 from both sides to get 5 as the solution
Answer:
ADDITION
16+f=x
Step 1: Add -16 to both sides.
f+16+−16=x+−16
f=x−16
Answer:
f=x−16
Step-by-step explanation:
SUBTRACTION
16−f=x
Step 1: Add -16 to both sides.
−f+16+−16=x+−16
−f=x−16
Step 2: Divide both sides by -1.
−f /−1 = x−16 /−1
f=−x+16
Answer:
f=−x+16

Jelani has twice as much money on his subway pass as Alexis. If they both add $20 to their passes, Jelani will have 1.5 times as much on his pass as Alexis. Write an equation to represent this situation. How much do Jelani and Alexis have on their subway passes now?
Answers
Answer:
x = 2x
x + 20 = 2x + 20
And,
1.5(x + 20) = 2x + 20
x = 20 i.e. Alexis
And, Jelani be 40
Step-by-step explanation:
Given that
Jelani has twice as much as Alexis
And, both can added $20
Jelani will have 1.5 times as much on his pass on Alexis
We need to write an equation also the amount does Jelani and Alexis have
So,
Let us assume the alexis be x
And, Jelani be 2x
Now
x = 2x
x + 20 = 2x + 20
And,
1.5(x + 20) = 2x + 20
1.5x + 30 = 2x + 20
-0.5x = -10
x = 20 i.e. Alexis
And, Jelani be 40

6. Angle A and Angle B are vertical angles. If the measure of Angle A is 30 degrees, what is the measure of Angle B?
Answers
Answer:
Angle B is 30 degrees
Step-by-step explanation:
Vertical angles are always congruent
Vertical angles are always of same measure. The measure of angle B in this case is evaluated as: [tex]m\angle B = 30^\circ[/tex]
What are vertical angles?Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.
They are always of same measure.
We can think about this fact as: "there were two lines overlaying on each other. Then, there was a finite point chosen, from where both decided to rotate by a certain degree. Since angle is measure of rotation, and as vertically opposite sides were equally rotated, so they get same measure:"
Its diagram is attached below. The vertical angles are congruent (denoted by ≅) (which is another way to say that they are of same measure)
Since the angle A and angle B specified in this case are pair of vertical angles, and since measure of angle A = 30 degrees, thus, angle B is also of measure 30 degrees.
The measure of an angle is written by writing small m in its left as: [tex]m\angle B = 30^\circ[/tex]
Therefore, the measure of angle B in this case is evaluated as: [tex]m\angle B = 30^\circ[/tex]

If h(x) = f(x) - g(x) = 2x, at what x-value will f(x) = g(x) + 20?
a) x = 20
b) x = 10
c) x = 5
d) x = 2
Answers
Answer:
B
Step-by-step explanation:
This is a neat question
f(x) - g(x) = 2x Add g(x) to both sides
f(x) = g(x) + 2x
Now you need the right hand side to have 20 added to g(x).
2x must = 20
2x = 20 Divide by 2
x = 20/2
x = 10
So the answer must be x = 10

An ecologist studying starfish populations collects the following data on randomly selected 1-meter by 1-meter plots on a rocky coastline

--The percentage of area in the plot that is covered by barnacles (food for starfish)
--Whether or not the plot is underwater midway between high and low tide
How many of these measurements can be treated as contituous random variables and how many as discrete random variables?
Answers
Answer:
2 continous random variable
1 discrete random variable
A fourth variable that cannot be treated as random.
Step-by-step explanation:
A continous random variable differs from a discrete variable in a few ways ; Continous random variables are usually uncountable as they can take up an infinite number of values within an interval. These variables may include those obtained by measurement such as height, weight, distance and so many other decimal yielding values. Discrete random variables in the other hand are countable and values can be obtained by counting as successive values are usually whole numbers.
In the scenario above ;
The weight of starfish and percentage area on the plot are continous variables while the number of starfish is discrete.
Whether or not plot is underway or midway between high and low tide isn't a random variable.
Suppose a theater cast has 28 actors, 8 of whom are men. Express the ratio of men to women in simplified rational form.
Answers
Answer:11/4
Step-by-step explanation:
8 actors are men so the number of women who are actresses will be
Total actors - male actors
Female actors = 28 - 8 = 20
The ratio of men to women = 8 : 20
To simplify, decrease ratio to its simplest form. The lowest common factor of both numbers is 2. Divide both sides by 2 until it can be divided no more
8 : 20 = 4 : 10 = 2 : 5
The ratio of men to women in simplified rational form is 2 : 5
