Answer:

Step-by-step explanation:

o find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

1. What is the slope intercept form for -3, and (4,2) SIMPLIFIED??

Ostrovityanka [42]

Answer:

Step-by-step explanation:

1. y - 2 = -3(x - 4)

y - 2 = -3x + 12

y = -3x + 14

2. y - 6 = -1/2(x + 5)

y - 6 = -1/2x - 5/2

y - 12/2= -1/2x - 5/2

y = -1/2x + 7/2

Our school swimming pool is 25 m long if our coach wants us to swim 3 km how many lengths of food will we need to swim ?

Masja [62]

So,

We will have to divide the length the coach wants you to swim by the length of your pool to find how many laps you must swim. However, we need to first convert 3 km to meters by multiplying by 1000 (because 1 km = 1000 m).

3 * 1000 = 3000 m

Now we can divide.

$\frac{3000}{25} = \frac{600}{5}= 120$

You will need to swim 120 laps (not a realistic number).

d). Diagonals of square are perpendicular-Never

Diagonals bisect angle of the square, i,e they bisect 90 degrees angle into 45 degrees

e). Diagonals of parallelogram are congurent-Always

Diagonals bisect the angle, so they are congurent.

f). If ABCD is parallelogram then , AB is congurent to CD -Always

since, Opposite sides of parallelogram are always equal and are congurent.

g). Square is a rectangle - Sometimes,

In square all the sides are equal where in rectangle only opposite sides are equal, so

square can be rectangle.

h). A parallelogaram is a rohmbus - Sometimes

A parallelogaram is a rohmbus is all the sides of parallelogaram is equal.
