The formula for the area of a triangle is, 1 А A= bh Calculate the height of a triangle when A= 24 m2 and b = 8 m.

Sphinxa [80]

I hope this helps you

A=1/2.b.h

given Area is 24 and base is 8

24=1/2.8.h

24=4.h (divide 4 both of sides)

h=6 (height)

Write an equation of four lines that intersect to form the sides of a parallelogram

horrorfan [7]

The question requires that the four lines that intersect form a parallelogram but not an specific parallelogram, so you are not restricted by a diagram.

You can use these equations for the four lines:

1) y = 0 (it is the x-axis)

2) y = 4 (it is a line parallel to the x-axis, whose y-intercept is 4.

3) y = x (it is an inclined line that intersects both y = 0 and y = 4 lines.

4) y = x + 7 (it is a line parallel to y = x, that also intersect the both y = 0 and y = 4 lines.

The diagram shows a row of four identical tiles, each in the shape of an isosceles trapezoid. What is the area of one tile?

VMariaS [17]

I saw the image that accompanied this problem.

4 identical isosceles trapezoid forming 2 parallelogram.
1 parallelogram has a base of 16 inches and its height is 10 inches.

We need to get the area of the parallelogram and multiply it by 2 before dividing it into 4 to get the area of each isosceles trapezoid.

Area of a parallelogram = base * height
A = 16 in x 10 in = 160 in²

160 in² x 2 parallelogram = 320 in²
320 in² / 4 tiles = 80 in²

The area of one tile is 80 square inches.

Determine if the scenario is independent or dependent:

Lady_Fox [76]

Answer:

dependent

Step-by-step explanation:

A scenario is called independent if the outcome of one event will not influence the outcome of the other. We are trying to assign a position for each player so that everyone gets a position. But we also need to make no one can have more than one position.

Let's say we have position X, Y, Z for player A, B, C. First you assign the position for player A, there will be 3 possible positions (A/B/C). If you assign position X to player A, player B can't get the X position so the possible outcome is only two(B or C). This makes the scenario dependent because the outcome of the first roll will influence the possible outcome of the next roll.
