HELP!!!!!!!!!!!!!!!!!!!!!!!!!! Can U Answer All These.

QUESTION 1

In figure A, the area of the bigger square is $625\:units^2$ . This means that the length of this square is the hypotenuse of the right angle triangle formed, which is $25\:units$ .

The area of the two smaller squares are $576\:units^2$ and $49\:units^2$ .

The length of these two squares form the two shorter legs of the right angle triangle, which are $24$ and $7$ units respectively.

Therefore we can write the equation, $576+49=625$ .

This implies that, $24^2+7^2=25^2$

We can see that the sum of the squares of the two shorter legs equals the square of the longer side which is the hypotenuse and this what the Pythagoras theorem says.

But in fig. B,

$5^2+4^2\ne 6^2$

Therefore the correct answer is Fig A.

QUESTION 2

See diagram.

We introduce the two lines as shown in the diagram.

From Pythagoras' Theorem,

$|AB|^2=|AC|^2+|BC|^2$

But $|AC|=|7-3|=4$ units.

and

$|BC|=|8-2|=6$ units.

This implies that,

$|AB|^2=4^2+6^2$

$|AB|^2=16+36$

$|AB|^2=52$

$|AB|=\sqrt{52}$

$|AB|=2\sqrt{13}$

$|AB|=7.2$ to the nearest tenth.

QUESTION 3

The numbers $3,4$ and $5$ form a Pythagorean triplet because $3^2+4^2=5^2$ .

If these numbers represent the side lengths of a triangular fence, then the triangular fence must be a right angle triangle.

The correct answer is B

Yes,because $3^2+4^2=5^2$ .

QUESTION 4

See graph.

We want to find the image of the triangle with vertices A(-5,-4), B(-2,-4), and C(-5,-1) after a reflection in the x-axis.

The mapping for this transformation is

$P(x,y)\rightarrow P'(x,-y)$ .

We just have to negate the y-coordinates.

$A(-4,-5)\rightarrow A'(-4,5)$ .

$B(-4,-1)\rightarrow B'(-4,1)$ .

$C(-5,-1)\rightarrow C'(-5,1)$ .

A parallelogram rotates about its center. At what angle of rotation will the image of the parallelogram coincide with its preima

zmey [24]

The correct answer is option C. i.e. When a a parallelogram rotates about its center., then taking 180 degrees as the angle of rotation, the image of the parallelogram coincide with its preimage. Thus 180 degree rotation is the answer.

Lesson 7 module 4 grade 6 please help me

torisob [31]

Length of rectangle

Rectangle 1) 23m
Rectangle 2) 14yd

Width of rectangle

Rectangle 1) 36m
Rectangle 2) 3.5yd

An expressions is an equations but without the equal sign ( = ) and without the solution ( the answer)

The formula To find the area of a rectangle is

A = base * height
or
A = length * width

Rectangle’s area written in as an expression

Rectangle 1) 23 * 36
Rectangle 2) 14 * 3.5

To find the area, you multiply the numbers

23 * 36 = 828
14 * 3.5 = 49

Rectangle’s area written as a number

Rectangle 1) 828m
Rectangle 2) 49yd
