Hi there! :)

Answer:

The answer is D. 25% of 180 is 45.

Step-by-step explanation:

Let's replace "what percent" with the letter "x" because it's what we are looking for.

The word "of" is the same thing as a multiplication sign, which means that the sentence "What percent of 180 is 45?" can turn into "x times 180 is 45".

The word "is" is the same thing as an equation sign, wich means that you can write this as an equation:

x × 180 = 45

180x = 45

Now all you have to do is solve this equation by isolating "x" to find your answer:

180x = 45

Divide each side of the equation by 180 → 45 ÷ 180 = 0.25

x = 0.25

0.25 = 25 ÷ 100 = 25%

There you go! I really hope this helped, if there's anything just let me know! :)

Describe and correct the error : |-13| - |13| = -13 - 13 = 26

hjlf

First,
|-13| represents the absolute value of the number 13. Absolute values cannot be negative. So |-13| cannot become -13, it would become 13.

So,
|-13| - |13| = -13 - 13 = 26 would become
|-13| - |13| = 13 - 13 = 0

A sequence of numbers begins with 12 and progresses geometrically. each number is the previous number divided by 2. which value

Viefleur [7K]

1/2 value can be used as the common ratio in an explicit formula that represents the sequence.

Definition of sequence -

The following of one thing after another; succession. order of succession: a list of books in alphabetical sequence.
A continuous or connected series: a sonnet sequence. something that follows; a subsequent event; result; consequence.

A sequence that progresses geometrically has the first term as 12.

Each number is the previous number divided by 2.

so the sequence will be 12, 6, 3, 1.5...........

Explicit formula of a geometric sequence is given by

$T_{n} = ar^{n-1}$
