The length of the side AB in triangle ABC is 6.58 units.
What are trigonometric ratios in terms of a right-angle triangle?
We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjacent/hypotenuse and
tan = opposite/adjacent.
From the given figure we can conclude that we have length of the adjacent
with an angle of 20° and we have been asked to find the hypotenuse.
We know cos = adjacent/hypotenuse.
∴ cos20° = adjacent/7.
0.937 = adjacent/7.
adjacent = 7*0.937.
adjacent = 6.58.
Hence , the length of the side AB in triangle ABC is 6.58 units.

SP when CPi is 380 and gain percentage is 25
Answer:
If the cost price (CP) is 380 and the gain percentage is 25%, we can use the following formula to find the selling price (SP):
SP = CP + (gain percentage/100) * CP
Substituting the given values, we get:
SP = 380 + (25/100) * 380
SP = 380 + 95
SP = 475
Therefore, the selling price is 475.

The numerical value of standard deviation can never be______
The standard deviation lies in the range of 0 to 1. The numerical value of standard deviation can never be negative.
The standard deviation is a measure of amount of variation or dispersion of a set of values. When we compare two unequal observations, the result is always greater than zero i.e., always positive.
Standard deviation is the square root of the variance of the observations and the root always gives values either positive or zero, it can never be negative.
Therefore, the numerical value of the standard deviation can be positive. The value of standard deviation is always greater or equal to zero.

Equilateral triangle abc has a perimeter of 96 millimeters. A perpendicular bisector is drawn from angle a to side at point m. What is the length of ? 16 mm 24 mm 32 mm 48 mm.
Option a is correct- The length of MC is 16mm.
The equilateral triangle has its three sides with the same length.
So if the perimeter is 96 mm, we have,
perimeter = 3 * side
3 * side = 96
side = 32mm
The segment MA is the height of the equilateral triangle, and its length can be calculated with the equation,
height = (side * root(3))/2
height = 16root(3)
Using the Pythagoras' theorem in the triangle ACM, we have,
side^2 = MC^2 +height ^2
1024 = MC^2 + 768
MC^2 = 256
MC = 16mm
so, The length of MC is 16mm.

Three spheres each with charge Q uniformly distributed through its volume Rank the spheres according to the magnitude of the electric field they produced at point P (greatest firstl P (1) (2) (3) Select one: a. 3 > 2 > 1 b. all tie c. 1>2>3 d. 1 and 2 tie > 3 e. 2 > 3 >1
The correct ranking of the spheres according to the magnitude of the electric field they produce at point P (greatest first) is: 1 > 2 > 3. The answer is option C.
Since all three spheres have the same charge Q and radius, the magnitude of the electric field at point P due to each sphere is proportional to 1/d^2, where d is the distance between the center of the sphere and point P. Therefore, the sphere closest to point P will produce the greatest electric field at that point.
Assuming that the three spheres are arranged in a straight line with sphere 1 being the closest to point P and sphere 3 being the farthest, we can rank the spheres according to the magnitude of the electric field they produce at point P as follows:
Sphere 1 produces the greatest electric field at point P since it is the closest to it.
Sphere 2 produces the second greatest electric field at point P since it is farther away from point P than sphere 1 but closer than sphere 3.
Sphere 3 produces the smallest electric field at point P since it is the farthest from it.

Brian was recording the height of a plant for a science project. The plant was 6 1/2 inches tall last week. After measuring the plan this week he recorded that the plant grew 1 1/4 inches. What is the height of the plant now
Answer:
The height of the plant now is 7 3/4 inches, as it has grown by 1 1/4 inches from the previous measurement of 6 1/2 inches.
Step-by-step explanation of how to calculate the height of the plant:
1. Measure the height of the plant last week, and record it (it is 6 1/2 inches).
2. Measure the height of the plant this week, and record it (it is 7 3/4 inches).
3. Subtract the height measured last week from the height measured this week (7 3/4 - 6 1/2 = 1 1/4 inches). This result indicates the amount the plant has grown.
4. Add the result from Step 3 (1 1/4 inches) to the height that was recorded last week (6 1/2 inches).
5. The final result is the current height of the plant, which is 7 3/4 inches.

Q is the centroid of the triangle. What is the length of QK?
Applying the centroid theorem, the length of QK in the triangle is: 10.
What is a Centroid of a Triangle?The centroid of a triangle is the point of intersection of the three medians of the triangle. A median is a line segment that connects a vertex of a triangle to the midpoint of the opposing side. T
What is the Centroid Theorem?The Centroid Theorem states that the centroid of a triangle is located two-thirds of the distance from each vertex to the midpoint of the opposite side.
In other words, if G is the centroid of triangle ABC, then AG = (2/3)AD, BG = (2/3)BE, and CG = (2/3)CF, where D, E, and F are the midpoints of sides BC, AC, and AB, respectively.
Therefore, given that:
Q is the centroid of ΔJKL
PQ = 5
Thus, PQ = 1/3(PK) [according to the centroid theorem]
Substitute:
5 = 1/3(PK)
15 = PK
PK = 15
QK = PK - PQ
QK = 15 - 5

how do you conversion ml to ounces
To convert milliliters (ml) to ounces (oz), multiply the number of milliliters by 0.033814. The conversion factor of 1 ml = 0.033814 oz is used to convert any given volume in milliliters to ounces.
In order to convert milliliters (ml) to ounces (oz), we use the conversion factor of 1 ml = 0.033814 oz. This means that one milliliter is equivalent to 0.033814 ounces. To convert any given volume in milliliters to ounces, we multiply that value by the conversion factor of 0.033814.
The result should be rounded off to an appropriate number of decimal places based on the level of precision required for the particular application.
For example, if we want to convert 500 ml to ounces, we would do:
500 ml * 0.033814 oz/ml = 16.907 oz
So, 500 milliliters is equal to 16.907 ounces.
Note that this conversion factor is exact, meaning that it has an infinite number of decimal places. However, when we round off the final result, we should choose an appropriate number of decimal places based on the level of precision that we need for the particular application.

The airplane is 10735.96 feet away from the control tower
The angle of depression from the top of the lighthouse to the boat is 0 degrees.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Using trigonometry, we can find the horizontal distance x:
tan(15) = x / 228
x = 228 tan(15)
x = 57.87 feet
Therefore, the horizontal distance between Ryan and the dolphin is 57.87 feet.
2. Using trigonometry, we can find the horizontal distance between the airplane and the control tower:
tan(56) = x / 7450
x = 7450tan(56)
x = 10735.96 feet
Therefore, the airplane is approximately 10735.96 feet away from the control tower
3. We want to find the angle of depression from the top of the lighthouse to the boat. Since the lighthouse is 275 feet above the water, we can use trigonometry to find the height of the lighthouse above the boat:
tan(90) = 275 / x
x = 275 / tan(90)
x = undefined
Therefore, the angle of depression from the top of the lighthouse to the boat is 0 degrees.

A rigid motion maps each part of a figure to an Rotation.
What is rotation ?
In physics, rotation refers to the movement of an object around an axis or a fixed point. When an object rotates, every point on the object moves in a circle around the axis of rotation, and the object typically completes one full rotation or revolution after it has moved a full 360 degrees around the axis.
The study of rotation in physics is important in many fields, including mechanics, electromagnetism, and quantum mechanics. Rotational motion is characterized by several key parameters, including the angle of rotation, the angular velocity (how fast the object is rotating), and the angular acceleration (how quickly the angular velocity is changing).
In addition, rotational motion is subject to a number of physical laws and principles, such as Newton's laws of motion, which describe the relationship between the forces acting on a rotating object and its resulting motion. Other principles, such as the conservation of angular momentum, relate to the conservation of the rotational energy of a system as it undergoes rotational motion.
Therefore, a rigid motion maps each part of a figure to an Rotation.
