55

Step-by-step explanation:

Answer:

55

Step-by-step explanation:

your trying to make it equal, in order to do that you must do to the top what you did the bottom

11 = ?

20=100

to get from 20 to 100 you multiply by 5 so we multiply the top by 5 to make it equal

11/20x5/5=55/100

Answer:

So if you have a 165 so the 5 is half of 10 so the 6 will got up but if you have 133 the three is lower then 5 so it would round down

Step-by-step explanation:

Answer:

Change in Y over change in X. So down 8 and over 2. Simplified it would be 4/1

Answer:

6

Step-by-step explanation:

The reason you would do 6 is because you need to isolate the  variable term.

This means you need the variable and its coefficient alone. so if you subtract 6 from each side of the equation you can achieve that goal. So the equation would then read -2x= -9 (because you combine the like terms of -6 and the -3 that was already there)

If you need to complete the rest of the equation you would divide both sides by -2 to further isolate x. This means x= 9/2 (since they are both negative they cancel each other out turning it positive) and the simplified answer would be 4  1/2

Answer:

8 and - 4

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (2.5, 14) ← 2 points on line A

\(m_{A}\) = \(\frac{14+6}{2.5-0}\) = \(\frac{20}{2.5}\) = 8

Repeat with (x₁, y₁ ) = (0, 8) and (x₂, y₂ ) = (2, 0) ← 2 points on line B

\(m_{B}\) = \(\frac{0-8}{2-0}\) = \(\frac{-8}{2}\) = - 4

The given statement "the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring." is False.

The union of two events A and B represents the event that at least one of the events A or B occurs. The probability of the union of two events can be calculated using the formula:

P(A or B) = P(A) + P(B) - P(A and B)

On the other hand, the intersection of two events A and B represents the event that both events A and B occur. The probability of the intersection of two events can be calculated using the formula:

P(A and B) = P(A) * P(B|A)

where P(B|A) is the conditional probability of B given that A has occurred.

It is possible for the probability of the union of two events to be greater than the probability of the intersection of two events if the two events are not mutually exclusive.

In this case, the probability of both events occurring together (the intersection) may be relatively small, while the probability of at least one of the events occurring (the union) may be relatively high.

In summary, the probability of the union of two events occurring can sometimes be greater than the probability of the intersection of two events occurring, depending on the relationship between the events.

At the instant when the bottom of the ladder is 6 ft from the wall and sliding away at a rate of 1 ft/sec, the top of the ladder is sliding down the wall at a rate of -3/4 ft/sec.

Let's denote the distance between the top of the ladder and the ground as y and the distance between the bottom of the ladder and the wall as x. We are given that dx/dt = 1 ft/sec and want to find dy/dt when x = 6 ft.

According to the Pythagorean theorem, we have the equation

\(x^2\) + \(y^2\) = \(10^2\).

Differentiating both sides with respect to time (t), we get:

2x(dx/dt) + 2y(dy/dt) = 0.

Substituting the given values, we have:

2(6)(1) + 2y(dy/dt) = 0.

Simplifying the equation, we get:

12 + 2y(dy/dt) = 0.

Now, we can solve for dy/dt:

2y(dy/dt) = -12,

dy/dt = -6/y.

To find dy/dt when x = 6 ft, we substitute x = 6 into the equation:

dy/dt = -6/y = -6/8 = -3/4 ft/sec.

Therefore, the top of the ladder is sliding down the wall at a rate of -3/4 ft/sec when the bottom of the ladder is 6 ft from the wall.

In summary, the equation 3x - 6 = 9 + 2x can be solved to find a single solution, which is x = 15. This means that when we substitute 15 into the equation, it holds true.

To explain the solution, we start by combining like terms on both sides of the equation. By subtracting 2x from both sides, we eliminate the x term from the right side. This simplifies the equation to 3x - 2x = 9 + 6. Simplifying further, we have x = 15. T

his shows that x = 15 is the value that satisfies the original equation. To confirm, we can substitute 15 for x in the original equation: 3(15) - 6 = 9 + 2(15), which simplifies to 45 - 6 = 9 + 30, and finally 39 = 39. Since both sides are equal, we can conclude that the solution is indeed x = 15.

The diameter of a wire significantly impacts its strength, range, and stiffness.

1. Strength: As the diameter of a wire increases, its overall strength improves. A larger cross-sectional area allows the wire to withstand greater forces before breaking. This is because the increased material can distribute force more effectively, resulting in enhanced tensile strength.

2. Range: The diameter of a wire also influences its range or length. Thicker wires tend to have shorter range capabilities compared to thinner wires. As the diameter increases, the weight and stiffness of the wire rise as well, making it harder to extend or coil over long distances. Conversely, thinner wires are more flexible and lightweight, enabling them to cover greater lengths.

3. Stiffness: Lastly, the diameter of a wire impacts its stiffness, which is the resistance of the wire to bending or deformation. With a larger diameter, the stiffness of the wire increases due to the higher amount of material present. This means that it requires more force to bend or change the shape of the wire, resulting in greater rigidity. On the other hand, wires with smaller diameters are more pliable and can easily be bent or manipulated.

In summary, the diameter of a wire plays a crucial role in determining its strength, range, and stiffness. Thicker wires exhibit enhanced strength and stiffness but may have limited range capabilities, while thinner wires are more flexible and suitable for longer distances but may not be as strong or rigid.

Correct question

At what point do the lines y = x - 8 and y = - 3x + 16 intersects?

Equating both expressions;

x - 8 = -3x+16

Collect like terms

x+3x = 16+8

4x = 24

x = 24/4

x = 6

Substitute x = 6 into any of the equation

Recall that y = x - 8

y = 6 - 8

y = -2

Hence the point (x, y) where they intersects is at (6, -2)

Answer:

Step-by-step explanation:

Since the length of the actual racecar is 19 feet, and the length of the model is represented by x, we can set up the following proportion:

Length (model) / Length (actual) = Width (model) / Width (actual)

This can be written as:

x / 19 ft = 1.4 in / 7 ft

To solve for x, we can cross-multiply and simplify:

x * 7 ft = 19 ft * 1.4 in

x = (19 ft * 1.4 in) / 7 ft

x = 3.8 in

Therefore, the length of the model is 3.8 inches.

To explain this solution in more detail, we can use proportionality concepts and unit conversions. The proportion relates the length and width of the actual racecar to the length and width of the model.

We set up the proportion with the length of the model as the unknown (x) and solve for it by cross-multiplying and simplifying. Since the width of the model and actual racecar are given in different units, we convert the width of the model from inches to feet before using the proportion.

The final answer is expressed in inches, which is the same unit as the width of the model.

There are 4,368 different ways to select an 11-player soccer team from a group of 16 players.

The combination formula is used to determine the number of ways to select items from a collection where the order of selection is irrelevant.

We can use the combination formula to determine the number of ways to select an 11-player soccer team from a group of 16 players. The combination formula is:

n choose k = n! / (k! * (n - k)!)

where n is the total number of items, k is the number of items to choose, and ! denotes the factorial function (i.e., the product of all positive integers up to and including the argument).

In this case, we want to choose k = 11 players from a group of n = 16 players. Therefore, the number of ways to select an 11-player soccer team from a group of 16 players is:

16 choose 11 = 16! / (11! * (16 - 11)!) = 4368

Therefore, there are 4,368 different ways to select an 11-player soccer team from a group of 16 players.

none of the provided options (a, b, c, d) appear to be accurate or close to the minimum space required.

To determine the minimum space required for a male restroom design with the given plumbing requirements, we need to consider the minimum space required for water closets and lavatories.

The minimum space required for water closets is typically around 30-36 inches per unit, and for lavatories, it is around 24-30 inches per unit.

Since the design requires a minimum of 12 water closets and 13 lavatories, we can estimate the minimum space required as follows:

Minimum space required for water closets = 12 water closets * 30 inches = 360 inches

Minimum space required for lavatories = 13 lavatories * 24 inches = 312 inches

Adding these two values together, we get a total minimum space requirement of 672 inches.

Among the given options, the closest value to 672 inches is option d) 249. However, this value seems significantly lower than the expected minimum space requirement.

Given that, the function s(t) describes the motion of a particle along a line. s(t) = t³ − 13t² + 35t − 220

We need to find the time intervals in which the particle moves in the positive direction and the negative direction.

The given equation is s(t) = t³ − 13t² + 35t − 220

Taking the derivative,

v(t) = s'(t) = 3t² -26t + 35 = velocity at time t

s'(t) = 3t² -26t + 35 = 0

(3t -5)(t-7) = 0

t = 5/3 and 7 seconds

Therefore, the velocity > 0 when s'(t) > 0, when t>7 or t < 5/3 seconds

velocity <0 when 5/3 < t < 7 seconds

When moving in a positive direction, the intervals :-

(-∞, 5/3) ∪ (7, ∞)

When moving in a negative direction, the interval :-
