Answer:

Step-by-step explanation:

You want to know the values of x and y that make the angle measures consistent with the triangles being congruent in the given figure.

The side markings show congruent triangles with corresponding vertices (and angles) ...

  L (3x+24)° ⇔ P (8x -11)°

  M 84° ⇔ Q 84°

  N (2x +y)° ⇔ R (no marking)

Corresponding angles L and P have the same measure, so ...

  3x +24 = 8x -11

  35 = 5x . . . . . . . . add 11-3x

  7 = x . . . . . . . . . divide by 5

The measures of these angles are ...

  (3(7) +24)° = 45°

The sum of the angles in each triangle is 180°, so the measure of angle N is found to be ...

  L +M +N = 180°

  45° +84° +N = 180°

  N = 51°

This lets us find the value of y from ...

  (2x +y)° = 51°

  2(7) +y = 51

  y = 37 . . . . . . . . subtract 14

The value of x is 7. The value of y is 37.

The perimeter measures around 36 metre.

The perimeter refers to the area surrounding an object. For instance, your house has a fenced-in yard. The perimeter is the length of the fence. If the yard is 50 feet by 50 feet, your fence is 200 feet long.

While 12.74 rounds up to 13, 5.45 rounds down to 5. Recatangle created a total of four sides, two of which are identical in length to the other two (which is a poor way to explain it). There are two sides that are 13 inches long and two sides that are 5 inches long, which is the solution to this question. When added together, the perimeter would be 13+13+5+5.

As an expression,

2(13)+2(5)

=26+10

=36.

The perimeter is approximately 36 meters.

========================

Let the central angle be α.

Note: You could get it more easily if considered 360° = 2π in your calculations.

Answer:

[tex]\dfrac{78}{5} \pi = 15.6 \pi[/tex]

Step-by-step explanation:

Given values:

As the arc length is given in terms of pi, use the formulas where the angle is measured in radians.

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Arc length}\\\\Arc length $=r \theta$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in radians.\\\end{minipage}}[/tex]

Substitute the given values into the arc length formula to calculate the central angle (in radians):

[tex]\implies 6\pi=5.2\; \theta[/tex]

[tex]\implies \theta=\dfrac{6\pi}{5.2}[/tex]

[tex]\implies \theta=\dfrac{15}{13}\pi[/tex]

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Area of a sector of a circle}\\\\Area of a sector = $\dfrac12 r^2 \theta$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in radians.\\\end{minipage}}[/tex]

Substitute the radius and the found angle into the formula and solve for area:

[tex]\begin{aligned}\implies \textsf{Area of the sector}&=\dfrac{1}{2}(5.2)^2 \left(\dfrac{15}{13}\pi\right)\\\\&=\dfrac{1}{2}(27.04) \left(\dfrac{15}{13}\pi\right)\\\\&=(13.52) \left(\dfrac{15}{13}\pi\right)\\\\&=\dfrac{78}{5}\pi \\\\&=15.6 \pi\end{aligned}[/tex]

3589.9 m is the height at which air pressure equals 65% of the air pressure at the surface of the Earth

Given: the function P(h) =P₀ e^(-0.00012h)

When air pressure equals 65% of the air pressure at the surface of the Earth. That means P = 0.65P₀

Substitute P = 0.65P₀ into the function:

P(h) = P₀ e^(-0.00012h)

0.65P₀  = P₀ e^(-0.00012h)

Dividing both sides by P₀ gives:

0.65  = e^(-0.00012h)

Take ln of both sides (ln is the inverse of e):

ln 0.65 = -0.00012h

h = ln 0.65/ (-0.00012)

h = 3589.9 m

Therefore, the height at which air pressure equal 65% of the air pressure at the surface of the Earth is 3589.9 m. Option D is the answer

The equation of the line that passes through the point (5,3) and has a slope of 3/5 is  y = 3 / 5x .

The equation of a line in slope intercept form can be represented as follows:

y = mx + b

where

The equation of the line passes through the point (5,3) and has a slope of 3/5. Therefore, let's find the y-intercept of the line using (5, 3)

y = 3 / 5 x + b

3 = 3 / 5 (5) + b

3 = 3 + b

b = 3 - 3

b = 0

The distance each player ran for warm up laps is 875 cm and the distance each player ran for the store is 1.47 meters.

According to the question,

We have the following information:

Adrianna’s football team ran some warm up laps with a total distance of 6125 centimeters. There are 7 players on her football team.

The distance to the store = 10.31 meters

Now, we can find the distance ran by each player by dividing the total distance by number of players.

Distance for warm up laps = 6125/7

Distance ran by each player = 875 cm

Distance for the store = 10.31/7

Distance for the store = 1.47 m

Hence, the distance each player ran for warm up laps is 875 cm and the distance each player ran for the store is 1.47 meters.

Equation of line having passing points (-6,0) and (0,-24) is 4x + y + 24 = 0

What do you mean by equation of line?

The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y-axis).

The variables x and y are related to coordinates on the line in the linear equation y = mx + c.

The formula y = mx + c yields a result for y when we enter a value for x.

As y depends on the value of x, it follows that x is an independent variable and y is a dependent variable.

Two passing points of line are (-6,0) and (0,-24)

Equation of line having two passing points as (a,b) and (c,d) is

[tex](y-b) = \frac{d-b}{c-a} (x-a)[/tex]

The slopes of the rays of the absolute value function, y = -3·|x + 2| + 8 are 3 and -3

In an absolute value function, an algebraic expression is contained within an absolute value symbol.

The given absolute value function is; y = -3·|x + 2| + 8

The slope of the rays are found as follows;

The general form of the absolute value function is; f(x) = a·|x - h| + k

The vertex of the function is the point (h, k)

The slope of the function is a

Comparing the specified function, y = -3·|x + 2| + 8, to the general function, we get;

The vertex of the function is (h, k) = (-2, 8)

The slope of the rays of the function are; a = 3

Slope of the ray 1 = (8 - (-19))/(-2 - (-11)) = 3

Slope of ray 1 is therefore; 3

Slope of ray 2 = (8 - (-19))/(-2 - 7) = -3
