Triangle LMN is positioned inside rectangle LKPN as shown in the diagram. Which is the area of △LMN?
Sati [7]

Step-by-step explanation:

The formula of a triangle is A=½bh

Base=6.5

Height=4.8(since the height if the triangle and the width of the rectangle are same)

A=½(6.5)(4.8)

A=½(31.2)

a =  \frac{31.2}{2}

A=15.6

Therefore, the area of the triangle LMN is 15.6

I hope this helps.

A 2 kg block rests on a shelf that is 3m tall. What is the Gravitational Potential Energy of the block? The forse of gravity on
Vaselesa [24]

Answer:

58.8Joules

Step-by-step explanation:

The gravitational potential energy = mgh

m is the mass = 2kg

g is the acceleration  due to gravity = 9.8 m/s²

h is the height = 3m

Substitute;

GPE = 2 * 9.8 * 3

GPE = 6 * 9.8

GPE = 58.8Joules

Hence the Gravitational Potential Energy of the block is 58.8Joules

zavuch27 [327]

Answer:

C. 8 units right and 5 units down

Step-by-step explanation:

since it's only a translation, take one point as an example. lets say the bottom right point on trapezoid P is point A, and the translated point on P' is A'. the coordinates of A are (-3,2) while the coordinates of A' are (5,-3). (-3+x,2+y)=(5,-3). -3+x=5, x=8; 2+y=-3, y=-5
