1. in cecilia’s cd collection, 1/5 of her jazz cds represents 1/10 of all her cds. what is the ratio of her jazz cds to her non-jazz cds? 2. how would you change 5^6(50) to a number times 25?

1. The ratio of Jazz and non-Jazz CDs is 1:1.

2. The given expression can be written as 25 times 31250 .

1. Given information:

In Cecilia’s CD collection, 1/5 of her Jazz CDs represents 1/10 of all her CDs.

Let jazz CDs be J in number and T be the total number of CDs.

The given condition can be written as,

So, the ratio of Jazz CDs to non Jazz CDs will be,

Therefore, the ratio of Jazz and non-Jazz CDs is 1:1.

2. The given expression is . It is required to write the given number as a number times 25.

So, it can be written as,

Therefore, the given expression can be written as 25 times 31250 .

1)

Ratio is 1:1.

2)

The required number is:

Step-by-step explanation:

1)

Let us consider that Cecilia's has a total of 'x' CDs

and let 'y' represent the number of Jazz CDs.

Now we are given information that:

1/5 of her Jazz CDs represents 1/10 of all her CDs.

i.e.

i.e. the Jazz CDs are half of the total CDs.

Hence, the number of Non-Jazz CDs(z)

=

Hence, the ratio of Jazz to Non-Jazz CDs

Hence, the required Ratio is 1:1.

2)

How would you change to a number times 25?

We will find the number by dividing the quantity   by 25 to find the required number.

i.e.

Hence the required number is:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
