Areas of paralleolgrams and triangles?

Mathematics

The area of parallelogram is

A=base\cdot height.

If base has length 9.9 in and height has length 5.5 in, then the area is A=9.9\cdot 5.5=54.45 sq. in.

When base has length 11 in and height is unknown h, then A=11\cdot h.

Since the area is 54.45 sq. in., then

54.45=11h,\\ \\ h=\dfrac{54.45}{11} =4.95 in.

Answer: h=4.95 in.

If M (6,8) is the midpoint of line segment AB, and if A has coordinates (2,3) , find the coordinates of B.
sveticcg [70]
Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.
If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.
Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.
Solving for the coordinates gives x2 = 10, y2 = 13

A scientist measures the angle x and the distance y between the Earth and the Sun. Using complete sentences, explain how the sci
yanalaym [24]

Answer:

The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:

The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:

cos x = BC / y

Solving for BC

BC = y cos x

BC is the distance between the Earth and the sun
