EastWind [94]3 years ago

Answer:

2/5

Step-by-step explanation:

From the two points we have marked, they are clearly 10 units apart from -5 to 5, and the change in the y-axis is 4. So the change between the two points is 4/10 (rise over run).

4/10 simplifies to 2/5.

The sum of a rational number and an irrational number?
Semenov [28]

Answer:

Is irrational

Step-by-step explanation:

Let r be a rational number, and i be an irrational number. If their sum were rational, say q, then we'd have

r+i=q \iff i=q-r

but q-r is the difference between two rational numbers, and thus a rational number. But it also equals i, which is irrational by hypothesis. Since we have a contradiction, we conclude that the sum of a rational and an irrational can't be rational.

ANTONII [103]

9670 feet

Step-by-step explanation:

The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?

we translate word problem to equation.

8219.5 IS 85% of TOTAL

Firstly, 85% = 85/100 = 0.85

Remember, is means =

of means multiplication

So we have:

8219.5 = 0.85 * Total

Hence, total = [let total be 7]

8219.5 = 0.85 * t

t = 8219.5/0.85 = 9670 feet
