Answer:

5:2 , 30:12 , 60:24 , etc.

Step-by-step explanation:

To identify ratios equivalent to 15:6, all you need to do is multiply or divide both numbers in the ratio by the same amount to find an equivalent ratio.

So, for example:

1:2 --> 1*2 : 2*2 = 2:4 Both one half, so equal.

Now for 15:6...

Let's divide by the least common denominator ( 3 )

15 / 3 and 6 / 3 = 5 and 2

So 15:6 = 5:2

And we can also multiply the ratio by any constant as well...

For example 15 * 2 and 6 * 2

So 30:12 = 15:6

Hope this helped!

49.5 is what percent of 33?
stira [4]
49.5/33 x 100= 150%. This is also rather simple to figure out just by looking at the question itself, you can clearly see that 49.5 is 16.5 greater than 33 and that 16.5 is half of 33. Which you can easily figure out from there.

What is the sum of the first thirteen terms in a geometric series with a<br> r = 3 a1= -10
Ipatiy [6.2K]

To calculate the sum of the first thirteen terms of the geometric series, we use the formula below.

Formula:

  • S₁₃ = a(rⁿ-1)/(r-1).............. Equation 1

Where:

  • S₁₃ = Sum of the first thirteen terms of the geometric series.
  • a = First term of the series
  • r = Common ratio

Given:

  • a = -10
  • r = 3
  • n = 13

Substitute these values into equation 1

  • S₁₃ = -10(3¹³-1)/(3-1)
  • S₁₃ = -7971615
