Answer:

360

Step-by-step explanation:

We find Wanda's reading speed in pager per hour, which is 180/2 3/4 = 180/2.75 = 65.4545...

To find how many pages she reads in 5 1/2 hours, multiply 65.4545... by 5 1/2, or 5.5 to get 360. She reads 360 pages in 5 1/2 hours

A cube with an edge of length s has a volume of 27 units.<br> What is the length of s?
matrenka [14]

Answer:

s = 3

Step-by-step explanation:

The volume formula for a cube is V = s^3, where “s” is the edge length. Since we know the volume and need to find “s,” we just do the inverse operation for an exponent, which is a radical. The cubed root of 27 is 3, so there’s your answer! Hope this is helpful & accurate. Best wishes.

How would you solve this problem?
photoshop1234 [79]

Answer:  [c, ∞)

<u>Step-by-step explanation:</u>

Range is all of the y-coordinates.

The parabola is upright (∪) because the coefficient of x² is positive.

So the minimum value is at "c" and the parabola tends toward infinity.

Range: y ≥ c    <em>in Interval Notation</em>: [c, ∞)
