Answer: True

Step-by-step explanation:

Suppose the length and width of the original rectangle is L and W

After dilation by a factor of y, it becomes yL and yW

Area of the original rectangle A_1=L\times W

The area of the dilated rectangle is A_2=yL\times yW=y^2LW

we can see that

\Rightarrow A_2=y^2A_1

What type of number is -16.2i
azamat

Answer:

Complex and imaginary number

Step-by-step explanation:

First, let's write the number-16.2i in the form of a+bi.

Compare the two ratios is 6 : 15 less than 30 : 80 or greater than?
romanna [79]

Work:
6/15 = x/1
To get from 15 to 1, you have to divide by 15. So, to make an equal field, divide 6 by 15.

6 : 15 is the same as 2 : 5 or 0.4.

30/80 = x/1
To get from 80 to 1, you have to divide by 80. So, to make an equal field, divide 30 by 80.

30 : 80 is the same as 3 : 8 or .875.


Comparing the two, 30 : 80 is greater than 6 : 15.


Hope this helps. Have a good day.

Helppppppppppppppp lol
Sladkaya [172]
The given expression is: 
(x/2) + 5

Let's look at each terms separately:
x/2 means that you you're getting half the value of a number
+5 means that you are adding 5
Combining both, you can conclude that you are adding 5 to half a certain given number.

Comparing this with the choices, the correct choice would be:
C. five more than half a number.
