The answer is D. x/11

Say you need to find the xth place in the sequence. Based on the fact that the 1st place is 1/11, the 2nd place is 2/11, and so on, to find the value of the xth place in the sequence the answer is x/11.

Answer:

The answer is D. $\frac{x}{11}$

Step-by-step explanation:

In order to determine the correct sequence, we need to find differences in the numerator and the denominator of the fraction between two continuous terms.

In the numerator, the number is increasing in one digit. The first term in the numerator of the sequense is 1, the second is 2, the third is 3, and so on.

In the denominator, the number is constant (11).

Therefore, we define a "x" variable that represents the number in the numerator. So to find the value of the nth place in the sequence is:

$\frac{x}{11}$

Find the value of each expression. Show your work.

Verdich [7]

Answer:

$A) (1.2)^{2} = 1.44$

$B)2^ 3+17-(3\times 4) = 13$

$C)\frac{(9)^2}{(3)^3} = 3$

Step-by-step explanation:

Here, the given expressions are:

A) $(1.2)^{2}$

Solving this, we get

$(1.2)^{2} = 1.2 \times 1.2 = 1.44$

⇒ $(1.2)^{2} = 1.44$

B) $2^ 3+17-(3\times 4)$

Now, solving this, we get

$2^ 3+17-(3\times 4) = (2 \times 2 \times2) + (17 -12)\\=8 + 5 = 13$

⇒ $2^ 3+17-(3\times 4) = 13$

C) $\frac{(9)^2}{(3)^3}$

Simplifying this, we get

$\frac{(9)^2}{(3)^3} = \frac{(9\times9)}{(3 \times 3\times3)} = 3$

⇒ $\frac{(9)^2}{(3)^3} = 3$

Evaluate . | 6a |- 10 for a = - 7

Ilia_Sergeevich [38]

The answer would be 32. This is because once you input -7 you multiply -7 and 6 and end up with -42 but since it is in absolute value it turns into positive 42. Now it is 42 - 10. At this point all you do is subtract which will get you 32. Hope this helps ; )
