Simplify: √54 + √486 + √24
Answer:
14√6.
Step-by-step explanation:
√54 = √9√6 = 3√6
√486 = √81 √6 = 9√6.
√24 = √4√6 = 2√6.
So √54 + √486 + √24
= 3√6 + 9√6 + 2√6
= 14√6.

Las longitudes de dos lados de un octágono regular están representadas por las expresiones 2x + 4 y 3x-8. Encuentra la longitud de un lado del octágono
Answer:
La longitud del lado del octágono es de 28 unidades.
Step-by-step explanation:
Si las longitudes de los dos lados pertenecen a un octágono regular, entonces se satisface la siguiente condición:
[tex]2\cdot x + 4 = 3\cdot x - 8[/tex] (1)
A continuación, despejamos [tex]x[/tex] en (1):
[tex]3\cdot x - 2\cdot x = 4 + 8[/tex]
[tex]x = 12[/tex]
Ahora, determinamos la longitud del lado del octágono: ([tex]x = 12[/tex])
[tex]l = 2\cdot x + 4[/tex]
[tex]l = 28[/tex]
La longitud del lado del octágono es de 28 unidades.

In a class of 25 students, 16 have a brother and 10 have a sister. There are 6 students who have a brother and a sister. What is the probability that a student chosen randomly from the class has a sister?
The probability that a student chosen randomly from the class has a sister, in a class of 25 students, is 2/5.
What is the addition rule of probability for two events?For two events A and B, we have:
Probability that event A or B occurs = Probability that event A occurs + Probability that event B occurs - Probability that both the event A and B occur simultaneously.
This can be written symbolically as:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
For three events, A, B and C:
[tex]P(A \cup B \cup C) = P(A) + P(B) + P(C) - P(A\cap B) - P(A \cap C) - P(B \cap C) + P(A \cap B \cap C)[/tex]
In a class of 25 students, 16 have a brother and 10 have a sister. There are 6 students who have a brother and a sister.
Let A is event of a student having a brother and B is event of a student having a sister.
The probability of event A is,
[tex]P(A)=\dfrac{16}{25}[/tex]
The probability of event B is,
[tex]P(B)=\dfrac{10}{25}\\P(B)=\dfrac{2}{5}[/tex]
The probability of occurrence of both event A and B together,
[tex]P(A\cap B)=\dfrac{6}{25}[/tex]
Thus, the probability that a student chosen randomly from the class has a sister, in a class of 25 students, is 2/5.

Step-by-step explanation:
The graph shows the daily sales goal of
a coffee shop. If the employees sell
20 cups of coffee, how many cups of tea
must they sell to meet their goal?
Answer:
25 cups of tea
Step-by-step explanation:
On the x-axis, we have the number of cups of coffee plotted against the number of cups of tea which are plotted on the y-axis to represent the daily sales goals.
From the graph, when 20 cups of coffee are sold (x = 20), a corresponding sales of 25 cups of tea (y = 25) would be sold as well to meet the sales goal.
Therefore, when employees sell 20 cups of coffee, 25 cups of tea must be sold to meet their goal.

x2 + 6x - 13 = 3
Answer:
x = 2
Step-by-step explanation:
x2 + 6x - 13 = 3
first you add 13 to other side and get
x2 + 6x = 16
next you combine x's
8x = 16
then you divde the 8x by 16
and you get x = 2

There are 6500 people in a certain area. The area is growing at a rate of 3.5%.
Use the formula A=Pertto calculate the time it would take for the area to reach 11500 people. Calculate the solution for t to the nearest tenth using logarithms.
Answer:
24,831.28
Step-by-step explanation:
Brainliest pls
Answer:
t = 16.6
Step-by-step explanation:
In the formula:
[tex]a = p(1 + r )^{t} [/tex]
A is the final amount, in this case is 11500 people. P is the initial amount, in this case is 6500 people. r is the growth rate, which in this case is 0.035 - we have to express it s a decimal, not a percent. And finally t is the time, which is the variable we want to find.
Let's clear t first and replace all these values at the end. To clear t we have to leave only the factor which exponent is t on one side of the equation. To do this we have to divide both sides by P:
[tex] \frac{a}{p} = \frac{p}{p} (1 + r) ^{t} \\ \frac{a}{p} = (1 + r)^{t} [/tex]
Now we have to use the following rule for the exponents and logarithms:
[tex] {a}^{x} = b[/tex]
Apply logarithms on both sides:
[tex]log( {a}^{x}) = log(b)[/tex]
By the exponents rule of logarithms
[tex]x \: log(a) = log(b)[/tex]
For this problem we have:
[tex]log \frac{a}{p} = log(1 + r)^{t} \\ log \frac{a}{p} =t \: . \: log(1 + r)[/tex]
Now we have to divide both sides by log(1+r) to clear t:
[tex]log \frac{a}{p} = t \: . \: \frac{log(1 + r)}{log(1 + r)} \\ t = \frac{log \: \frac{a}{p} }{log(1 + r)} [/tex]
And finally we just have to replace the values into this equation we found: A = 11500, P = 6500 and r = 0.035:
[tex]t = log \: \frac{11500}{6500} \\ log(1 + 0.035) \\ log \: \frac{23}{13} \\ t = log \: 1.035 \\ t = 16.6[/tex]

On Sarah's shelf are 6 mystery books,5 science books,4 history books, and 3 adventure books. What is the probability of NOT selecting a mystery book?
Answer:
Probability of Sarah NOT selecting a mystery book = 0.67
Step-by-step explanation:
Probability helps to show how likely an event will occur;
The probability an event will not occur can be obtained by subtracting the probability that the event will occur from 1.
We can take this route to solve this problem
The probability of picking an option from a broad list of alternatives can be calculated using the formula:
Probability = number of expected outcomes/ total number of options
For our problem, there are only 6 mystery books on the shelf. Hence, the number of expected outcomes is = 6. Sarah cannot pick any more than 6 mystery books, and any mystery book she picks will be from that lot.
The total number of options refers to the total number of books available to pick from; whether mystery, science history, and adventure.
We can get this by adding 6 + 5 + 4 + 3 = 18
Probability of Sarah selecting a mystery book = 6/18
Probability of Sarah NOT selecting a mystery book = 1 - (6/18) = 0.67

Find the perimeter and total area of the composite shape shown below. All measurements are given in inches. Use pi=3.14 in any formulas used.
Answer:
Perimeter of the entire shape is 114.24
Step-by-step explanation:
Use pi x diameter of the semicircle divided by 2 + the diameter to find the perimeter of one semicircle. There are 4 semi circles so you multiply this by 4. Then you take the perimeter of the inside 8x4 = 32. Add them all together to get 114.24

What is the area in square centimeters of the trapezoid below
Answer:
39.6 cm²
Step-by-step explanation:
The formula for the area of a trapezoid is given as:
Area of a Trapezoid = 1/2(a + b) h
Where, from the question:
a = 8.9 cm
b = 5.5 cm
h = 5.5cm
Hence,
1/2 (8.9cm + 5.5cm) × 5.5cm
= 1/2 × 14.4 cm × 5.5 cm
= 39.6 cm²
Area of the Trapezoid = 39.6 cm²
