If 2 = 6, 3 =12, 4 = 20, 5 = 30, 6 = 42 then 9 = ?
Soloha48 [4]
At first you may get confused but look at those numbers carefully :)

as you see first result is divisible buy one of the product (second product in all cases is unknown)
so let's check where it will lead us :)

6/2=3

12/3=4

20/4=5

30/5=6

42/6=7

Now you can clearly see that every number was multiplied by number 1 higher than itself. 
2*(2+1)=6

3*(3+1)=12

4*(4+1)=20

etc...

it means that after equation sign there should be 90 because 

9*(9+1)=90 :)

Morgarella [4.7K]
$49.9 more interest

2680x1.07=2867.6
3069x1.045=3197.7

2867.60-2680=187.6
3197.7-3069=137.7

187.6-137.7=49.9

Hunter-Best [27]

Answer:

To represent parts of whole numbers, we use fractions.

So if 4 kids are sharing 3 cookies, what happens?

First, we divide one cookie into four equal parts, and give one part to each kid. Then we do the same with the second cookie, and then with the third one.

In the end, each kid will have three pieces. Each piece is a whole cookie divided into four equal parts.

So we represent this amount as

3 (Number of parts) & 4 (How many equal parts the whole is divided into)

3

4

as a fraction

A fraction is made of two numbers :

The angles when added give the sum of 90 degrees and are called complementary angles. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

In the given figure it is observed that the two angles ∠a and ∠b when added give 90 degrees.

Therefore, the relation between the two angles ∠a and ∠b is that they are complementary angles. The correct option is B.
