Based on the definition of a right angle, the value of x is: B. 40.

A right angle is an angle that measures exactly 90 degrees, or one quarter of a full circle. The symbol used to represent a right angle is a small square placed in the corner where the two lines or rays meet

Therefore, if two parts of a right angle measures 10 degrees and 2x respectively, we would have:

2x + 10 = 90

Subtract 10 from both sides:

2x = 90 - 10

2x = 80

2x/2 = 80/2

x = 40

What is a square?

A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles. It can also be explained as a rectangle with two adjacent sides that are of equal length.

Given that fencing is sold in 8-foot sections at $15 per section and the fence posts cost $4 each.

The length of each side is 240 feet.

The perimeter of the square field is 4×240 = 960 feet.

The number of sections that need to fence the field is 960/8 = 120.

The number of posts that need to fence the field is 120.

The cost of 120 Fencing sections is 120×$15 = $1800.

The cost of 120 posts is 120 × 4 = $240.

To find the scale factor of the dilation, we can compare the corresponding dimensions of the original and the enlarged card.

The original card has a length of 3 1/2 inches and is being enlarged to a length of 5 1/4 inches. So the scale factor for the length is:

5 1/4 inches / 3 1/2 inches = 3/2

Similarly, the original card has a width of 2 inches and is being enlarged to a width of 3 inches. So the scale factor for the width is:

3 inches / 2 inches = 3/2

Therefore, the scale factor of the dilation is 3/2 or 1.5.

The probability that a random sample of 150 bowlers will have an average score greater than 165 is 0

Probability is a branch of mathematics that deals with the study of random events or outcomes. It is used to measure the likelihood or chance of an event occurring, ranging from impossible (0 probability) to certain (1 probability).

The basic concept of probability involves determining the ratio of the number of favorable outcomes to the total number of possible outcomes. This ratio is expressed as a fraction, decimal, or percentage.

For example, if you toss a fair coin, there are two possible outcomes: heads or tails. The probability of getting heads is 1/2 or 0.5 or 50%, and the probability of getting tails is also 1/2 or 0.5 or 50%.

To give the probability that a random sample of 150 bowlers will have an average score greater than 165

P( [tex]\bar X[/tex]> 165) = P(z > (165 - 157)/(12/√(150)))

x^2 + 4x + 4 is a perfect square trinomial that can be factored as (x + 2)^2.

Explanation:
To complete the expression x^2 + 4x + __ as a perfect square trinomial, we can take half of the coefficient of x (which is 4), square it, and then add it to the expression.

Half of 4 is 2, and 2 squared is 4, so we can add 4 to the expression to get:

x^2 + 4x + 4

This expression is a perfect square trinomial and can be factored as:

(x + 2)^2

Answer:

Step-by-step explanation:

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of a line is a measure of how steep the line is, and it is defined as the change in y divided by the change in x between any two points on the line. In other words, if we choose two points (x1, y1) and (x2, y2) on the line, then the slope of the line is:

m = (y2 - y1) / (x2 - x1)

The y-intercept of a line is the point where the line crosses the y-axis. In other words, it is the value of y when x = 0. To find the y-intercept of a line given in slope-intercept form, we simply look at the constant term (the term with no x) in the equation.

In the given equation, y = -6x - 7, we can see that the coefficient of x is -6, which means that the slope of the line is -6. This tells us that as we move along the line from left to right, the y-value will decrease by 6 units for every 1 unit that the x-value increases. In other words, the line is sloping downwards from left to right.

To find the y-intercept of the line, we look at the constant term, which is -7. This tells us that when x = 0, y is equal to -7. So the y-intercept is the point (0, -7), which means that the line crosses the y-axis at the point (0, -7).

To summarize, the slope of the line y = -6x - 7 is -6, which means that the line is sloping downwards from left to right. The y-intercept of the line is (0, -7), which means that the line crosses the y-axis at the point (0, -7).

a)The value of acceleration will be 4.8 m/s²

b)The total distance travelled is 505 m.

a) As all the movement happens along a straight line, we need to define an axis only, which we call x-axis, being the positive direction the one followed by the car.

We can choose to place our origin at the location where the motorcycle was stopped at the side of the road (assuming that it is the same point  for the car when it passes him), so our initial position is 0.

We can also choose our time origin to be the same as the instant that the motorcycle starts from rest, so t₀ = 0.

With these assumptions, and assuming also that the acceleration is constant, we can write two equations, one for the car (at constant speed) and the another one for the motorcycle, as follows:

xc = vx*t

xm= 1/2*a*t²

When the motorcycle passes the car, both distances traveled from the origin will be equal each other, i.e., xc = xm :

⇒ vx*t = 1/2*a*t²

We have as givens vx=35 m/s and t = 14.5 sec when both equations are equal each other.

⇒ 35 m/s* 14.5 s = 1/2*a*(14.5)²(s)²

Solving for a:

a = (2* 35 m/s) / 14.5 s = 4.8 m/s²

b) Replacing the value of a in the equation for xm, we have:

xm = 1/2*4.8 m/s²* (14.5)²s² = 505 m.

Answer:

The efficiency of the transmission and drive mechanism is 57.5%, rounded to two decimal places.

Step-by-step explanation:

We can use the following formula to calculate the efficiency of the transmission and drive mechanism:

Efficiency = (Power output / Power input) x 100%

where "Power output" refers to the amount of power delivered to the driving wheels, and "Power input" refers to the amount of power produced by the engine.

Determine the power input: The problem states that the automobile engine produces 120 horsepower, so this is our power input.

Power input = 120 hp

Determine the power output: The problem states that only 69 horsepower is delivered to the driving wheels of the car, so this is our power output.

Power output = 69 hp

Calculate the efficiency using the formula:

Efficiency = (Power output / Power input) x 100%

Substituting the values we found in steps 1 and 2, we get:

Efficiency = (69 / 120) x 100%

Simplifying this expression, we get:

Efficiency = 0.575 x 100%

Efficiency = 57.5%

Therefore, the efficiency of the transmission and drive mechanism is 57.5%, rounded to two decimal places.

Step-by-step explanation:

If the generation time of bacteria is 30 minutes, it means that in every 30 minutes, the number of cells will double. Let No = 100 be the initial number of cells, and n be the number of generations at that point.

Using the given formula N1 = N x 2^n, we can find the number of cells at any given time t, in minutes.

For t = 30 minutes:

The number of generations in 30 minutes is 1 (since generation time is also 30 minutes)

N1 = 100 x 2^1 = 200 cells

For t = 60 minutes:

The number of generations in 60 minutes is 2 (since generation time is 30 minutes)

N1 = 100 x 2^2 = 400 cells

For t = 90 minutes:

The number of generations in 90 minutes is 3 (since generation time is 30 minutes)

N1 = 100 x 2^3 = 800 cells

For t = 120 minutes:

The number of generations in 120 minutes is 4 (since generation time is 30 minutes)

N1 = 100 x 2^4 = 1600 cells

Therefore, after 30 minutes, the number of cells will be 200, after 60 minutes it will be 400, after 90 minutes it will be 800, and after 120 minutes it will be 1600.
