Is this a irrational or rational number?

Mathematics

The value 18 is rational but the sqrt(5) is irrational. Multiply a rational with an irrational, and you get irrational. Overall, the entire expression is irrational. There is no way to represent this value as a fraction of whole numbers.

note: "sqrt" is shorthand for "square root"

Write an equation for the line that is parallel to the given line and that passes through the given point. y = –5x + 3; (–6, 3)
Nutka1998 [239]
You would need a new y-intercept in order for this to be parallel. So you use the points given and the slope and fill it in. 3=-5(-6)+b. 3=30+b. Then subtract 30 from both sides. -27=b. Then just put it all back into slope intercept form. y=-5x-27.

nalin [4]

Answer:

Zamzam could make $400 per day.

Step-by-step explanation:

Given:

Zamzam can sell 1 liter of camel milk for $1.

Jasmin herd produces 400 liters per day.

Now, to find the money Zamzam could make per day.

By multiplying we get the money zamzam could make:

<em>If cost of 1 liter milk = $1.</em>

<em>Then cost of 400 liters milk = $1 × 400.</em>

                                              =  $400.

Therefore, zamzam could make $400 per day.
