your recipe calls for 1/2 a pound of potatoes. You use 1/6 of the bag of potatoes. whats the number of pounds per bag
zhannawk [14.2K]
I you use 1/6 of the bag for 1/2 a pound then you need to set up a proportion.

1/6 bag / 1 bag = 1/2 pound / x pounds      Cross Multiply
(1/6)*x = 1/2 pounds * 1 bag Divide by 1/6

Remember: in a 4 level fraction, the denominator inverts and multiplies.


x = {x = }\frac{ \frac{1}{2} }{ \frac{1}{6} } \\ \\ {x =} \frac{1}{2} *  \frac{6}{1} \\ \\{x = }  \frac{6}{2} = 3

Three bells ring at an interval of 10,20,and 30 minutes respectively. If they all ring together at 10:30 p.m.,at what time will
Ahat [919]

Answer:

11:30 PM

Step-by-step explanation:

This question is essentially asking for the lowest common multiple of 10, 20, and 30. If we write out all the multiples of each, we get:

10: 10, 20, 30, 40, 50, 60, 70, ...

20: 20, 40, 60, 80, ...

30: 30, 60, 90, ...

As you can see, the lowest common multiple is 60, and 60 minutes after 10:30 PM is 11:30 PM.

Given the function ƒ(x) = x^2 - 4x - 5
pychu [463]
F(x) = x² - 4x -5, factored is simply f(x) = (x - 5)(x + 1).

if you zero out f(x), namely 0=(x-5)(x+1), that simply gives you the zeros of 5 and -1.

now, from ----- -1------0---------------------------------5, notice from -1 to 5, there are 6 units, and half of 6 is 3, so, the half-way is 3 units away from either zero.

so we can get to the half-way point by -1 + 3, or 2, x = 2, that's where the vertex is at, but you already knew that, and of course the y-coordinate is at f(2) = (2)² - 4(2) - 5, which is -9, so the vertex is indeed at (2, -9).

now to draw it, well, surely you can, simply use the zeros location, -1 and 5, and draw a bowl between them, with the bottom of the bowl at 2, -9.

I think it’s the one with acute because it’s less than 90 degrees
