Answer:
-√64: rational
15 pi: irrational
46.86 repeated: rational
15/19: rational
-2√6: irrational
Step-by-step explanation:
From the picture that I used, I was able to find out which ones were rational and irrational.
-√64: rational because it equals to -8
15 pi: has "pi" in it
46.86 repeated: as long as it's repeated, it's rational
15/19: fractions are usually rational
-2√6: √6 is cannot be rationalized
Answer:
7.5 litres.
Step-by-step explanation:
Volume of water lost in 1 month = 2.5 * 10^-4 * 3 * 10^5
= 2.5 * 3 * 10^(-4+5)
= 7.5 * 10^1
= 7.5 litres (answer)
A = 1/2 bh
A = 1/2 • (6x + 4)(x-7)
Use FOIL to multiply the binomials
A = 1/2 • 6x^2 - 3x - 28
Multiply the (1/2) in
A = 3x^2 - 3/2x - 14
