B = 5sqrt(2)

Answer:

2

Step-by-step explanation:

For this equation, x = 1/2 makes it true.

4x + 1 = 3

To find a value for x that makes this equation true, we need to find a value where 4x + 1 equals 3.

  4x + 1 = 3

Subtracting 1 from both sides:

  4x = 2

Dividing both sides by 4:

  x = 2/4

  Simplifying:

  x = 1/2

Substituting x = 1/2 into the equation:

  4 .  1/2 + 1 = 3

  2 + 1 = 3

  3 = 3

Answer:

85 ft

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let h be the hypotenuse, then

h² = 40² + 75² = 1600 + 5625 = 7225 ( take the square root of both sides )

h = [tex]\sqrt{7225}[/tex] = 85

Answer:

85

Step-by-step explanation:

The most obvious way to solve this is by using the Pythogream therom which I strongly reccomend learning.

[tex]a^{2} + b^{2} = c^{2}[/tex]

Answer:

x = - 1

Step-by-step explanation:

Given

15x - 7 = 4x - 18 ( subtract 4x from both sides )

11x - 7 = - 18 ( add 7 to both sides )

11x = - 11 ( divide both sides by 11 )

x = - 1

BECAUSE I KNOW!!!

Answer:

The solution to this system of equations is x = -3 and y = 4.

Step-by-step explanation:

In order to solve this system we will use the second equation, which have the "y" isolated on the left side and use that value for "y" in the first equation. This is shown bellow:

5x + 4(1 - x) = 1

5x + 4 - 4x = 1

5x - 4x = 1 - 4

x = -3

Now we can use the value we found for x in the second equation to determine y.

y = 1 - x

y = 1 - (-3) = 1 + 3

y = 4

So the solution to this system of equations is x = -3 and y = 4.

Step-by-step explanation:

The average rate of change over the interval [tex][a,b][/tex] for a function [tex]f[/tex] is [tex]\frac{f(b)-f(a)}{b-a}[/tex].

So the average rate of change for [tex]f(x)=2^x[/tex] on [tex][2,4][/tex] is:

[tex]\frac{2^4-2^2}{4-2}=\frac{16-4}{2}=\frac{12}{2}=6[/tex].

Answer:

Explanation:

Any multiple of 3 and 4 shall blow clouds of smoke through its nostrils and breathe fire. Those are:

Hence, that is 8 dragons that shall have both characteristics.

Any multiple of 6 shall have glowing eyes. The common multiples of 6 and 3 are: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, and 96.

Then, that adds:

Hence, add 8 more dragons.

And the common multiples of 6 and 4 are: 12, 24, 36, 48, 60, 72, 84, and 96, all of which are already included.

Any multiple of 8 shall have a tail with spikes on it. Then, you must find the common multiples of 8 and 3, 8 and 4, and 8 and 6.

Common multiples of 8 and 3 are: 24, 48, 72, and 96, which are already included.

Common multiples of 8 and 4 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, and 96. Then, you must add:

Those are other 8 dragons.

At the end the number of dragons that shall have more than one of these characteristics is:

Final answer:

By calculating the least common multiples (LCMs) of the intervals for the dragon's characteristics and considering the first 100 dragons, we find that there will be 12 dragons with overlapping features.

Explanation:

Sir Dwayne at the King's Toy Factory is tasked with creating dragons with characteristics that occur at different intervals. Specifically, every 3rd dragon billows smoke, every 4th breathes fire, every 6th has glowing eyes, and every 8th has a spiked tail. We are asked to calculate how many of the 100 dragons will have more than one of these features.

To solve this problem, we need to consider the least common multiples (LCMs) between the provided intervals: 3, 4, 6, and 8. The LCM of any two numbers is the smallest number that is a multiple of both numbers. We'll find the number of dragons that have characteristics occurring at multiple intervals (overlapping features).

We must not forget to find the LCM for all three and four characteristics together, if any, to see if there is any dragon with three or all four features:

Since the highest LCM (which covers all the characteristics) is 24, and we are making 100 dragons, we can divide 100 by 24 to find how many dragons would have all four characteristics. This results in 4 dragons with some remaining. Now, we'll consider all unique multiples of our LCMs up to 100 and sum them up, taking care not to double-count any dragons:

Note that every multiple of 24 is also a multiple of 12, which means these have already been counted. So, we only count the additional multiples of 12 that are not multiples of 24.

Counting all the unique multiples, we have: 8 (from LCM 12) + 4 (from LCM 24) = 12 dragons. Thus, Sir Dwayne will make 12 dragons having more than one of these characteristics.

Answer:

V=7+6+8/2

Step-by-step explanation:

The probability of rolling double threes with two number cubes is calculated by multiplying the likelihood of each die showing a three independently, which is 1/6. Since each die is independent, the combined probability is 1/6 x 1/6 or 1/36.

When rolling two number cubes, often referred to as dice, the probability of rolling double threes is determined by considering the likelihood of each event occurring independently. Each die has six faces, so the probability of rolling a three-on-one die is 1/6. Since the outcome of rolling the second die is independent of the outcome of the first die, its probability of showing three is also 1/6.

The combined probability of both independent events occurring—that is, rolling a three on both dice—is found by multiplying the probabilities of the individual events. This means the probability is 1/6 multiplied by 1/6, which equals 1/36. So, the chance of rolling double threes is 1/36.

If we were discussing a different combination, such as rolling a one and a three, we would add the probability of the first die rolling a one and the second a three to the probability of the first die rolling a three and the second a one. But in the case of double threes, there is only one possible outcome that meets the criteria (a three on the first die and a three on the second) and therefore only one product of probabilities to consider.

To find the other endpoint of the diameter of a circle, you can use the midpoint formula in reverse with the given center and one endpoint. In this case, the coordinates of the other endpoint of the diameter are (5, 7).

The coordinates of the other endpoint of a diameter of a circle given that one endpoint and the center of the circle are known. We know the center of the circle, O, is at (2, 3) and one endpoint of the diameter is at (-1, -1). The diameter of a circle is a straight line through the center connecting two points on the circle. If you have one endpoint (x₁, y₁) and the center (x₂, y₂), the coordinates of the other endpoint (x₃, y₃) can be calculated using the midpoint formula in reverse:

x₃ = 2 × x₂ - x₁

y₃ = 2 × y₂ - y₁

For this circle:

x₃ = 2 × 2 - (-1) = 4 + 1 = 5

y₃ = 2 × 3 - (-1) = 6 + 1 = 7

So, the coordinates of the other endpoint of the diameter are (5, 7).

The word describing 3y is "term". The correct option is (D).

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given algebraic expression is as below,

5x + 3y + 9

Since an algebraic expression consists of different terms separated by each other by a plus or minus sign.

The given expression has three terms as  5x, 3y and 9.

Hence, the word that describes 3y for the given expression is "term".

Final answer:

In the expression 5x + 3y + 9, the term '3y' is one of the three terms present, with '3' serving as the coefficient, making '3y' correctly identified as a term.

Explanation:

In the given expression 5x + 3y + 9, the term "3y" is described as a term. In algebra, a term is a single mathematical expression that may form a part of a larger expression, which can include numbers, variables (like x or y), or the product of numbers and variables. Here, "3y" is one of the three terms in the expression, with "5x" and "9" being the others. The number 3 in "3y" is called the coefficient, which is the numeric part of the term that multiplies the variable y. Therefore, the correct answer to the question is D) term.
