A. 54 7/9
B. 15 1/3
C. 164 1/3
D. 30 2/3

Answer:

2/5

Step-by-step explanation:

it is 2/5

Probability = 12/25 or 48%.

To find the probability that a number chosen at random from the positive, even integers from 2 to 50 is divisible by 3 or 8, we need to count the number of even integers within this range that are divisible by 3 or 8, and then divide this count by the total number of even integers in the range.

First, let's find how many even integers between 2 and 50 are divisible by 3.

The even integers divisible by 3 in this range are: 6, 12, 18, 24, 30, 36, 42, 48.

Count: 8

Now, let's find how many even integers between 2 and 50 are divisible by 8.

The even integers divisible by 8 in this range are: 8, 16, 24, 32, 40, 48.

Count: 6

Notice that 24 and 48 are counted twice because they are divisible by both 3 and 8. We only want to count them once.

So, the total count of even integers between 2 and 50 that are divisible by 3 or 8 is 8 (from being divisible by 3) + 6 (from being divisible by 8) - 2 (counting 24 and 48 once) = 12.

Now, we calculate the total number of even integers between 2 and 50:

Total even integers between 2 and 50 = (50 - 2) / 2 + 1 = 25

Now, we can calculate the probability:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

            = 12 / 25

            = 0.48

So, the probability that a number chosen at random from the positive, even integers from 2 to 50 is divisible by 3 or 8 is 0.48.

Answer:

428,820,000 pounds

Step-by-step explanation:

The amount of garbage is number of person times the amount produced by each person. Thus, we have:

Amount of Garbage (in pounds) = 2.61 × 10^5 * 1.643 × 10^3

Note: We multiply 2.61 and 1.643, which is 4.28823 & multiplying 10^5 and 10^3 is 10^(5+3) = 10^8

Thus, we have 4.28823 * 10^8 = 428,823,000 pounds

This is approximately 428,820,000 pounds, last answer choice.

The solution to the given inequality is [tex]b\leq 1.7[/tex]

From the question, we to determine the solution to the inequality.

To determine the solution of the inequality, we will determine the value of the variable. The variable in the given question is b.

The inequality can be solved as shown below.

[tex]\frac{7}{2} \geq b + \frac{9}{5}[/tex]

Multiply through by 10

That is,

[tex]10 \times \frac{7}{2} \geq 10\times b + 10\times \frac{9}{5}[/tex]

This becomes

[tex]5 \times 7 \geq 10b + 2 \times 9[/tex]

[tex]35 \geq 10b + 18[/tex]

Now, subtract 18 from both sides

[tex]35 - 18\geq 10b + 18-18[/tex]

[tex]17 \geq 10b[/tex]

This becomes,

[tex]10b \leq 17[/tex]

Divide both sides by 10

[tex]\frac{10b}{10} \leq \frac{17}{10}[/tex]

[tex]b\leq 1\frac{7}{10}[/tex]

OR

[tex]b\leq 1.7[/tex]

Hence, the solution to the given inequality is [tex]b\leq 1.7[/tex]

solve for x

[tex]102\°=(160\°-x\°)[/tex]

[tex]x=160\°-102\°=58\°[/tex]

Answer:

see explanation

Step-by-step explanation:

Given f(x) = - 20x² + 23x - 6

To find the zeros set f(x) = 0, that is

- 20x² + 23x - 6 = 0 ( multiply through by - 1 )

20x² - 23x + 6 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 20 × 6 = 120 and sum = - 23

The factors are - 15 and - 8

Use these factors to split the x- term

20x² - 15x - 8x + 6 = 0 ( factor the first/second and third/fourth terms )

5x(4x - 3) - 2(4x - 3) = 0 ← factor out (4x - 3)

(4x - 3)(5x - 2) = 0

Equate each factor to zero and solve for x

4x - 3 = 0 ⇒ 4x = 3 ⇒ x = [tex]\frac{3}{4}[/tex]

5x - 2 = 0 ⇒ 5x = 2 ⇒ x = [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

Answer:

The figure obtained is a cylinder

The exact surface area is 1440π.

Step-by-step explanation:

* Lets study the rotation of a rectangle around one of its sides

- If the dimensions of the rectangle are length (L) and width (W)

- If we rotate the rectangle around its length (L), we will construct

 a cylinder with radius = W and height = L

- If we rotate the rectangle around its width (w), we will construct

 a cylinder with radius = L and height = W

∵ The surface area of any cylinder =

   perimeter of base × height + 2 base area

∵ The base is a circle

∴ perimeter base = 2πr and base area = πr²

∴ The surface area = 2πrh + 2πr²

* In first case:

- Surface area = 2π(W)L + 2π(w)² = 2πWL + 2πW²

* In second case:

- Surface area = 2π(L)W + 2π(L)² = 2πLW + 2πL²

* Now lats check our question:

∵ L = 22 and W = 18

- It will rotate around the largest side

∴ It will rotate around L

∴ The figure obtained is a cylinder

* From the explanation above this is the first case

∵ L = 22 and W = 18

∵ The surface area = 2πWL + 2πW²

∴ The surface area = 2 × 18 × 22 × π + 2 × (18)² × π

                                = 792π + 648π = 1440π

* The exact surface area is 1440π.

60 people claimed they they got at least eight hours of sleep.

Answer:

Step-by-step explanation:

We know that 30 people claimed that they get an average of seven hours of sleep. Using the circular diagram, we find that these 30 people represent 25% of the total number of people.

According to the graph, people that get at least eight hours of sleep each night represent 65%, that is, 50% of the people sleep eight hours and 15% sleep nine or more.

Then, we use the rule of three, if 30 people represent 25% of the total, how many people would represents 65%?

[tex]x=65\%\frac{30 \ people}{25 \%} = 78 \ people[/tex]

Therefore, 78 people claimed that they get at least eight hours of sleep each night.

In this algebra problem, we created two equations from the problem and solved them simultaneously, finding that Darlene burns 15 calories per minute jogging and 10 calories per minute cycling.

This question is about working out two equations using two variables, a classic application in

algebra

. Let's call the calories burned per minute jogging as

J

, and the calories burned per minute cycling as

C

. From the information given in the question, we know that:

These equations can be solved simultaneously. To make things easier, let's multiply the second equation by 2, which gives us:

By subtracting equation 1 from this, we get:

30C = 300

, simplifying this, we find that

C = 10 calories per minute for cycling

. Substitute C=10 into the first equation, we get:

20J + 100 = 400

, which simplifies to

J = 15 calories per minute for jogging

. Thus, Darlene burns 15 calories for each minute of jogging and 10 calories for each minute of cycling.

Answer:

Hello there! How are you doing? I am doing fine! I'll answer the question now.

So basically, your hunger would be satisfied with the 2 slices of 8 inches, because although one slice of 8 inches is two inches less than the 10 inch slice. But then you could add another 8 inch slice and it would make it greater and bigger than the one 10 inch slice itself. So in conclusion, the 2, 8 inch slices would be better than the 1, 10 inch slice because 16 inches is greater than 10 inches.

Hope this helped! Your welcome! I can help with other history stuff too! And byee! :)

Step-by-step explanation:

Two slices from an 8-inch pizza provide more pizza than one slice from a 10-inch pizza based on the calculation of the areas of the pizza slices. Therefore, your hunger would be better satisfied with the two pieces from the 8-inch pizza.

The subject here is a mathematical comparison of the area of different pizza sizes and the number of slices eaten. The location of a pizza can be calculated using the formula for the circle size, which is πr², where r is the radius of the pizza.

In the case of a 10-inch pizza, the radius is 5 inches (half of the diameter). So the area is π(5)² = 78.5 square inches. One slice of this pizza would be 1/8th of the total area, approximately 9.81 square inches.

For an 8-inch pizza, the radius is 4 inches. So the area is π(4)² = 50.24 square inches. Two slices of this pizza would amount to 1/4th of the total area, approximately 12.56 square inches.

So, when it comes to fulfilling your hunger at lunch, two slices of an 8-inch pizza would be more satisfying as it offers more pizza than one slice of a 10-inch pizza.

The given function is

[tex]f(x) = - (x + 5)(x + 1)[/tex]

Expand

[tex]f(x) = - ( {x}^{2} + x + 5x + 5)[/tex]

[tex]f(x) = - ( {x}^{2} + 6x + 5)[/tex]

[tex]f(x) = - {x}^{2} - 6x - 5[/tex]

a=-1,b=-6,c=-5

The x-value of the vertex is given by

a=-1,b=-6,c=-5

[tex]x = \frac{ - b}{2a} [/tex]

[tex]x = - \frac{ - 6}{2( - 1)} = - 3[/tex]

The y-value of the vertex is

[tex]f( - 3) = - ( - 3 + 5)( - 3 + 1)[/tex]

[tex]f( - 3) = - ( 2)( - 2) = 4[/tex]

Since a=-1, the function opens downwards.

The highest value is the y-value of the vertex which is 4.

Therefore the range is all real numbers less than or equal to 4.

The correct choice is A.

Answer:

(x - 7)² + (y - 2)² = 130

Step-by-step explanation:

The first step is finding the length of the radius.

r² = (2 - -5)² + (7 - -2)²

    = 7² + 9²

    = 49 + 81

   = 130

The general equation of a circle is:

(x - a)² + (y - b)² = r²

Where (a, b) is the coordinate of the center and r is the radius.

∴ The equation of the required circle is;

 (x - 7)² + (y - 2)² = 130
