Student Council sells bottled water at the cheerleading completion. At this rate, how many cases of bottled water would they sel
amid [387]

Answer:

27

Step-by-step explanation:

Lets find the rate of selling:

Let v= the rate of selling, b = number of bottles of water, and t = time:

b over t gives us the v=\frac{b}{t}=\frac{3}{20}=\frac{6}{40}=0.15 rate of selling:

3 hours is 60min * 3 = 180 mins, and since v=b/t, vt=b:

(0.15) * 180 = 27 bottles of water

4x2 + 4x =- 4<br> Find the solutions to the Quadratic equation.
VashaNatasha [74]

Answer:

x=-3

Step-by-step explanation:

(4)(2) + 4x = -4

                   multiply the 4 and 2

8 + 4x = -4

                   subtract 8 from both sides

4x = -12

                   divide both sides by 4

x = -3

PLEASE HELP ive been stuck on this for a long time
Tomtit [17]

Answer:

Below

Step-by-step explanation:

You can use Pythagorean theorem to find the hypotenuse of a right triangle.

a2 + b2 = c2

The square root of 15 = 3.8729.... (a bunch of other numbers)

4^2 + 3.8729^2 = c2

16 + 15 = 31

Now that you have this, you need to find the square root

The square root of 31 = 5.56775436

Rounding this to the tenth it would be: 5.57

Final answer: C = 5.57

hope this helps! :)

Step 1: Add 5 to both sides.

y−5+5=−2/3x−6+5

y=−2/3x−1
