) If the pattern shown continues, how many black keys appear on a portable keyboard with 49 white keys? Suggestion: use equivale
andriy [413]

Answer:

35

Step-by-step explanation:

Here we see 5 black keys for every 7 white keys.

So the ratio is 5:7

If we need 49 white keys, find the amount we scale the original ratio by:

    49/7 = 7

So we are scaling by a factor of 7.

The number of black keys would be 5 * the scale of 7. = 35

So there should be 35 black keys.

What is the quotient (x3 – 3x2 + 3x – 2) ÷ (x2 – x + 1)?
timofeeve [1]

We need to find the quotient of the given division problem.

\frac{x^{3}-3x^{2}+3x-2}{x^{2}-x+1}

In order to find its quotient, we will use long division.

x^{2}-x+1)x^{3}-3x^{2}+3x-2

First of all, we put x in the quotient as x^{2} goes into x^{3}, x times.

So, we get:

x^{2}-x+1)x^{3}-3x^{2}+3x-2(x

\text{ ..................}x^{3}-x^{2}+x

Upon subtracting, we get:

\text{....................}-2x^{2}+2x-2

We can see that x^{2} goes into -2x^{2}, -2 times, therefore, the next term in the quotient will be -2. This makes our quotient as (x-2).

Including Jose, there are eight people in his family.
SIZIF [17.4K]

Answer:

840

Step-by-step explanation:

Since the order matters, we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

In this question:

The first seat is Jose's.

The remaining four are organized among the other 7 members. So

P_{(7,4)} = \frac{7!}{(7-4)!} = 840

So the correct answer is:

840
