A 1080 foot cable weighs 307 pounds. How much will 36 inches of cable weigh? Round to 2 decimal places
noname [10]

Answer:

0.85 pounds

Step-by-step explanation:

1080 foot cable = 307 pounds

36 inches/2.9999988ft = (2.9999988 x 307) / 1080 = 920.9996316/1080 = 0.85277743666 pounds ≈ 0.85 pounds

1 inch = 0.0833333 ft

36 inch = 36 x 0.0833333 = 2.9999988 ft

A jar contains 5 blue marbles, 6 yellow marbles, and 4 green marbles. What is the probablity of randomly choosing a yellow marbl
marusya05 [52]

First, you need to choose a yellow marble. That is 6/15.

Next, you need to choose a blue marble. That is 5/14, because 1 yellow marble would have been "chosen" already.

So the probability altogether is 6/15 * 5/14 = 1/7, or about 14%.

Please help I'm bad at math i don't understand
dybincka [34]

Answer:

a) Vertex is at (-3, -1)

b) y-intercept is at (0,8)

c) x intercept is at (-4,0) and (-2,0)

d) x=-3

Step-by-step explanation:

The vertex of a parabola is the lowest or highest point, implying that all points are reflected across it. It's the only y value that doesn't have a corresponding pair.

For example, -1 and 1, -3 and 3, and so on.

The vertex is at (-3,-1) because it is the sole point without a corresponding y value (-3,-1)

The y-intercept is where the parabola meets the y axis or when the x value equals 0. To determine the y-intercept, simply find when x = 0.

intercept y: (0,8)

The x-intercepts are the same as the y-intercepts; you must determine where the parabola crosses the x-axis or when y = 0.

x intercept 1:(-4,0)

x intercept 2: (-2,0)

The axis of symmetry is also the x coordinate of the vertex which is 3 so

x = 3
