Sum of the angle measures of the quadrilateral = sum of all the angles of the rectangle which is equal to 360°

<h3>What is a Rectangle?</h3>

Rectangle: A rectangle is a quadrilateral. The opposite sides are parallel and equal to each other. Each interior angle is equal to 90 degrees.

The sum of all the interior angles is equal to 360 degrees. The diagonals bisect each other. Both the diagonals have the same length.

It is given that it is a Rectangle ABCD has 4 right angles

sum of all the angles of a rectangle = 90°+90°+90°+90°=360°

If we move vertex A to a different location without changing vertex angle then it can be moved to C because its diagonal of A

Sum of the angle measures of the quadrilateral = sum of all the angles of the rectangle which is equal to 360°

Martin will earn $20 per hour at a new job. During training he will earn $15 per hour. What percent of Martin’s regular hourly r

Contact [7]

Answer:

75%

Step-by-step explanation:

To find the percentage, you would divide the training hourly rate by Martin's regular hourly rate and multiply the quotient by 100

If martin normally earns $20 and he earns $15 during training, that means you would divide 15 by 20.

15/20=.75 and .75x100=75, so Martin earns 75% of his regular hourly rate during training

Check all of the ordered pairs that satisfy the equation below.y=2/5x

zvonat [6]

We are going to do this step by step:

Let's start with option A

X = 25 and Y = 5/2

$y=\frac{2}{5}\cdot x=\frac{2}{5}\cdot25=\frac{2\cdot25}{5}=\frac{50}{5}=\frac{5\cdot10}{5\cdot1}=10$

In this case, when X = 25 , then Y = 10 ,which is different to 5/2

X = 14 , Y = 35

$y=\frac{2}{5}\cdot14=\frac{28}{5}$

In case, when X = 14, then Y = 28/5, which is different to 35

X = 40 , Y = 24

$y=\frac{2}{5}\cdot40=\frac{80}{5}=16$

Similarly, in this case, when X = 40, then Y = 16, which is different to 24

X = 10 , Y=4

$y=\frac{2}{5}\cdot10=\frac{20}{5}=4$

Now, in this case, we can see that when X = 10, then Y = 4 which is the same as the given value of Y

X = 50 , Y = 20

$y=\frac{2}{5}\cdot50=\frac{100}{5}=20$

In this case, the values of Y are also the same.

X = 30 , Y = 12

$y=\frac{2}{5}\cdot30=\frac{60}{5}=12$

Again, in this case, the values of Y are the same, so the pair satisfies the equation.

In conclusion: options D, E and F satisfy the equation

Identify all sets to which the number -3/4 belongs

leonid [27]

Answer:

a. rational numbers

Step-by-step explanation:

we observe that -3/4 is a proper fraction (i.e it is a rational number)

hence

1) It cannot be a whole number

2) it cannot be an integer

therefore any answer choices that mention whole number or integer is not correct. By default, only a is correct.
