How do you find the percent of increase from 12 to 18?

1 answer:

4 0

Let's get the data out of the problem:

Nv = 18

Ov = 12

Now, we can apply in this equation that relates the new and the old values:

i = Nv / Ov

i = 18 / 12

i = 1.5

Now, we just consider what has passed from 1, and this is 0.5, converting to percentage it is:

p = 0.5 . 100

p = 50%

The increase was 50%.

Hope it helps.

What is the probability against drawing a 7 from a standard deck of 52 cards ? ( percentage% )

MaRussiya [10]

In a standard deck of cards, there are 48 cards that are not sevens. Therefore the probability of not drawing a seven is 48/52 = 12/13 (92.31%).

Answer:

1. 52 degrees 2. D

Step-by-step explanation:

1. The interior angles of a triangle add up to 180, so you can do 180 - 36 - 92 to find the third angle.

180 - 36 - 92 = 52 degrees

2. the angle XYZ has to equal the sum of the angles WXY and XWY. This means that 115 = 45 + XWY

115 - 45 = 72

XWY = D. 70 degrees

4. Name the first five terms of the arithmetic sequence. a1 = -35, d=4

Answer:

Step-by-step explanation:

We first have to write the equation for the sequence, then finding the first five terms will be easy. Follow the formatting:

$a_n=a_1+d(n-1)$ and we are given enough info to fill in:

$a_n=-35+4(n-1)$ and

$a_n=-35+4n-4$ and

$a_n=-39+4n$ or in linear format:

$a_n=4n-39$ where n is the position of the number in the sequence. We already know the first term is -35.

The second term:

$a_2=4(2)-39$ so

$a_2=8-39$ and

$a_2=-31$

The third term:

$a_3=4(3)-39$ and

$a_3=12-39$ so

$a_3=-27$ and we could go on like this forever, but the nice thing about this is when we know the difference all we have to do is add it to each number to get to the next number.
