Answer:

15 grams .

Step-by-step explanation:

We need to multiply the percentage as a decimal (0.30) with the amount of chocolate (50 g):

0.30*50 = 15 g

There are 15 grams of cocoa in the chocolate bar.

<h3>Answer:  15 grams of cocoa</h3>

Work Shown:

30% = 30/100 = 0.30

30% of 50 = 0.30*50 = 15

Here's another way to think about it: If we had 100 grams of chocolate and 30% are cocoa, then we have 30 grams of cocoa by definition of what percentage means. Divide the 100 in half to get 50, so we'll have to divide the 30 in half to get 15.

Only the circled ones

2.

M must be (0,0) since it coincides with the origin
R must be (a+b, √(a²-b²)).
The x-coordinate is b from A translated to the right by a.
The y-coordinate is the same as A.

(I think the square root is there to confuse you).

3.

R(0,0)
C(a,b) (same x as T, same Y as E)

5.

Not sure how to prove that.

Using the Associative Property which expression is equivalent to (2+x)+4=
Anna35 [415]

Answer:

x+6

Step-by-step explanation:

The given expression is (2+x)+4.

The associative property is :

(a+b)+c= a+(b+c)

Here,

a = 2, b = x and c = 4

So,

(2+x)+4 = 2+(x+4)

= x+6

So, the equivalent expression is x+6.
