Is 1.5 over 7.5 a rational number

1 answer:

5 0

Yes, because you can simplify it to .2 which can be written as a fraction. Irrational numbers are those ones that keep going with an infinite string of numbers past the decimal.

If a, b, and c are positive integers, what

r-ruslan [8.4K]

The greatest common factor is 2ab

To determine this you need to determine what is divide in both 18 and 8. The only number that can divide in both numbers is 2. Which means they have a common factor/number. And then you continue looking at the expression and see what other numbers or letters are common. The only common thing besides the number is a and b since it’s found in both. There is no c in 18ab.
Hope this makes sense

Please mark as a brainliest (crown) above my comment. Would be much appreciated

Find the length of GI in the triangle below. Show your work.

love history [14]

Answer:

The length of GI is 90.06 units

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

GH = 60 units

HI = 42 units

∠H = 123°

2. Using the Law of Cosines, we can find the length of GI, this way:

GI² = GH² + HI² - 2 * GH * HI * cos ∠H

Replacing with the real values:

GI² = 60² + 42² - 2 * 60 * 42 * cos ∠123°

GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545

GI² = 3,600 + 1,764 + 2,746.8

GI² = 8,110.8

GI = √ 8,110.8 = 90.06 units
