Pretty, pretty, pretty please help!!!Which proportion models this problem?

1 answer:

8 0

8 of 19 players said that they had 2 or more siblings.

8 out of 19 is equal to what out of 570

8/19 = x/570

This proportion can be written in different ways.

8/19 = x/570 cross multiplies to 19*x = 8*570

The task is to find a proportion among the answer options that cross multiplies to the same equation.

Option C is x/570 = 8/19. That cross multiplies to 19*x = 8*570 and is the correct answer.

Answer: There are 6 pieces of cloth are rectangles and 9 pieces of cloth are triangles.

Explanation:

Since we have given that

For every 5 pieces of cloth, 2 are rectangles

So, remaining piece will be of triangle so,

$5-2=3$

3 are triangles.

Ratio of rectangles to triangles is 2:3.

Now, she needs 15 pieces of cloth to complete her scarf,

So, Number of rectangles is needed is given by

$\frac{2}{5}\times 15\\\\=2\times 3\\\\=6$

Number of triangles is needed is given by

$\frac{3}{5}\times 15\\\\=3\times 3\\\\=9$

Hence, there are 6 pieces of cloth are rectangles and 9 pieces of cloth are triangles.

Explain how you can tell if a rational expression is in simplest form. Include an example with your explanation.

yan [13]

The numerator and denominators will have no common factors.

For example 4/6 is not in its simplest form because both 4 and 6 can be divided by 2. In simplest form this will be 2/3.
