Answer:

Step-by-step explanation:

An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.

Therefore we have the equation:

[tex]\dfrac{x+8}{10}=\dfrac{2x-5}{14}[/tex]              cross multiply

[tex]14(x+8)=10(2x-5)[/tex]             use the distributive property

[tex](14)(x)+(14)(8)=(10)(2x)+(10)(-5)[/tex]

[tex]14x+112=20x-50[/tex]           subtract 112 from both sides

[tex]14x=20x-162[/tex]           subtract 20x from both sides

[tex]-6x=-162[/tex]         divide both sides by (-6)

[tex]x=27[/tex]

The ones that give a rational number answer are:

C+D

A*B

C*D

A*A

Step-by-step explanation:

A+B does not give a rational number answer; √3+2√3 = 3√3

C+D is a rational number; √25=5 and √16=4; 5+4=9.

A+D is not a rational number; √3+√16 = √3+4

A*B is a rational number; √3*2√3 = 2√9 = 2*3 = 6

B*D is not a rational number; 2√3*√16 = 2√3*4 = 8√3

C*D is a rational number; √25*√16 = 5*4 = 20

A*A is a rational number; √3*√3 = √9 = 3

Answer:8>4n=6 or 8>4+n=6

Step-by-step explanation:

Let's solve the equation step by step. The problem statement can be translated into a mathematical equation:
"Eight more than the product of a number and 4 is equal to 6."
Let x be the number we are looking for. When the problem says "the product of a number and 4," we can express this as 4 * x or 4x. The phrase "eight more than" implies we are to add 8 to the product of the number and 4, making the expression 4x + 8. According to the statement, this expression is equal to 6. Thus, we write the equation as:
4x + 8 = 6
To find the value of x, we will follow these steps:
1. Subtract 8 from both sides of the equation to isolate the term with x on one side.
4x + 8 - 8 = 6 - 8
This simplifies to:
4x = -2
2. Divide both sides of the equation by 4 to solve for x.
4x / 4 = -2 / 4
This simplifies to:
x = -1/2
So the number we were looking for, represented as x, is -1/2.

The formula of a volume of a cylinder:

[tex]V=\pi r^2H[/tex]

r - radius

H - height

We have r = 6cm and H = 8cm. Substitute:

[tex]V=\pi(6^2)(8)=\pi(36)(8)=288\pi\ cm^3[/tex]

[tex]\pi\approx3.14\to V\approx(288)(3.14)=904.32\ cm^3[/tex]

Answer:

904.32 cm³

Step-by-step explanation:

The volume (V) of a cylinder is calculated using the formula

V = πr²h ( r is the radius of the base and h the height )

here r = 6 and h = 8, so

V = 3.14 × 6² × 8

   = 3.14 × 36 × 8 ≈ 904.32 cm³

Final answer:

The expression that is 444 times as large as the expression 34 - 15 is (4 x 34) - 15.

Explanation:

To find the expression that is 444 times as large as the expression 34 - 15, we need to multiply the expression by 444. The correct expression is option C, which is (4 x 34) - 15. Let's break it down:

First, we perform the multiplication: 4 x 34 = 136.

Then, we subtract 15 from the result: 136 - 15 = 121.

Therefore, the expression (4 x 34) - 15 is 444 times as large as the expression 34 - 15.

Step-by-step explanation:

Answer:

The answer would be graph A.

Step-by-step explanation:

Since the cards all belong to four suites, the king can be a heart as well as the jack, but they cannot be the same card. So the choice is graph A.

A Venn diagram displaying events A, B, and C, with overlaps representing the king of hearts (A intersect B) and the jack of hearts (B intersect C), correctly describes the description given.

The Venn diagram that represents the description given should consist of three overlapping circles, one for each event: choosing a king (event A), choosing a heart (event B), and choosing a jack (event C).

Since there is one king and one jack in the hearts suit, the events are not mutually exclusive and the intersections between the circles will represent these possibilities.

There will be an overlap between events A and B, which represents the king of hearts, and an overlap between events B and C, which represents the jack of hearts. However, there will not be an overlap between events A and C since a card cannot be a king and a jack simultaneously.

Answer:

Final answer:

The probabilities are matched as follows: A-24%, B-76%, C-19%, and D-25%. These are calculated based on the total number of balls of each color and the fraction that are labeled to win a prize.

Explanation:

The question provides a scenario where there are 24 yellow balls and 76 red balls in a box, and one-fourth of each color are labeled "Win a prize." We are asked to match descriptions of probabilities with their corresponding percent values.

A: Probability that a randomly selected ball labeled "Win a prize" is yellow = (1/4 * 24) / ((1/4 * 24) + (1/4 * 76)) * 100 = 6 / (6 + 19) * 100 = 24%.

B: Probability that a randomly selected ball labeled "Win a prize" is red = (1/4 * 76) / ((1/4 * 24) + (1/4 * 76)) * 100 = 19 / (6 + 19) * 100 = 76%.

C: Probability that a randomly selected ball is labeled "Win a prize" and is red = (1/4 * 76) / 100 = 19%.

D: Probability that a randomly selected yellow ball is labeled "Win a prize" = (1/4 * 24) / 24 * 100 = 25%.

Answer:

10

Step-by-step explanation:

The perimeter will also be halved:  (1/2)(20) = 10.

Example:  a rectangle of length 14 ft and width 8 ft has perimeter P = 2(14 ft) + 2(8 ft), or 28 ft + 16 ft = 44 ft.

If we halve the length and width, we get 7 ft and 4 ft, and the P is

2(7 ft) + 2(4 ft) = 14 ft + 8 ft = 22 ft, which is half of the original perimeter 44.

Before 0, it hadn't been dropped. After 2.5sqrt(10), it has hit the ground and stopped falling.Positive Real Numbers. This includes fractions of seconds, the other two don't.

The appropriate domain for the function describing the height of a ball dropped from a 1,000 feet high building as a function of time is 0 <= x <= 25 seconds, indicating the ball's descent time until it hits the ground.

The student has asked about the appropriate domain for a function describing a ball dropped from a height of 1,000 feet, given by the equation f(x) = 1,000 - 16x². To find the domain, we need to understand when the ball hits the ground, marking the end of its free fall and the function's practical use.

The height (f(x)) becomes 0 when the ball reaches the ground. Setting the equation to zero gives us 0 = 1,000 - 16x². Solving for x, we find x = 25 seconds. This means the ball will hit the ground after 25 seconds, indicating the end of its descent and the maximum value of x in the domain. Therefore, the appropriate domain for this function, representing the time from when the ball was dropped until it hits the ground, is 0 ≤ x ≤ 25 seconds.

Answer:

4 inches

Step-by-step explanation:

If you divide 18 by 6, the answer is three, so it is scaled down 3x.

So, you have to divide 12 by 3, and the answer is 4.

Answer: 4 Inches

Step-by-step explanation: The rectangle on the left shows that the length is 18 inches and the height is 12 inches. Now, to find the height on the right, First we must realize what changed has been made from the left to the right. We know that our length has decreased to 6 inches from 18. 18 can be divided by 3 and that will give us the quotient of 6. Now, we must divide our height on our original rectangle by 3 as well. Once we divide, our new height of our rectangle also known as X will be 4 Inches Long.

You can use the Pythagorean Theorem to find the hypotenuse. Then you should be able to find the altitude.

First you must have the quadratic equal to zero. In order to do this you must subtract 7 to both sides

x^2 + 20x + (100 - 7) = 7 - 7

x^2 + 20x + 93 = 0

Now you must find two numbers who's sum equals 20 and their multiplication equal 93
