Basically there are 3 addition properties and they are associative property, identity property, and commutative property.

Commutative property is just changing the order of the addends. Example: 26+19+34+21= 21+34+19+26

Identity Property is just adding a 0 to the number that doesnt change anything. Example: 26+19+34+21 +0 = 100

Associative property is just changing the grouping of the addends. Example: (26+19) + (34+21)

I know these properties may be complicated i know inhate them too haha but i hope i helped :) if you want you can search up the distributive property too but its with multiplication and addition combined and its harder but i think these are the 3 main properties.

Shilpa bought 30 T-shirt at a clothing store. 20% of the t-shirt were blue and 1/2 of the t-shirts were black. Howmany of the t-
k0ka [10]
The number of T-shirt bought by Shilpa from a clothing store = 30
Percentage of T-shirt that were blue = 20%
Then Number of T-shirt that were blue in color = (20/100) * 30
                                                                           = 2 * 3
                                                                           = 6
Number of T-shirts that were black in color = (1/2) * 30
                                                                     = 15
Then
The total number of T-shirts that were black and blue = (15 + 6)
                                                                                     = 21
Then
The total number of T-shirts that were neither black nor blue = 30 - 21
                                                                                                 = 9
So the number of T-shirts that were neither black nor blue was 9.

Answer:

The correct answer is choice D.

Step-by-step explanation:

Since the parabola opens sideways, that means the function will feature y^2 and not x^2, so you can immediately rule out options B and C. Because the graph also opens right, that means the coefficient of y^2 is positive. Using all of this information, you'll find that the correct answer is D: x = \frac{1}{12} y^2.

lara31 [8.8K]

Answer:

If 11 oranges cost $2.35, then the cost of 18 oranges is $3.84.

Step-by-step explanation:

We have,

The number of oranges purchased varies directly as the price of the oranges.

If the cost of 11 oranges is $2.35.

It is required to find the cost of 18 oranges.

As their is direct relation between number and oranges and price.

So,

The cost of 1 orange is $\dfrac{2.35}{11}.

For finding the cost of 18 oranges, multiply 18 by $\dfrac{2.35}{11} such that,

C=18\times \dfrac{2.35}{11}\\\\C=3.84

So, If 11 oranges cost $2.35, then the cost of 18 oranges is $3.84.
