Mathematics

Put the values of w = 12 and x = 1/2 to the expression 15 - 0.75w + 8x.

15 - 0.75(12) + 8(1/2) = 15 - 9 + 4 = 6 + 4 = 10

A box is 12 in, high, 24 in. long, and 8 in. wide. What is the longest poster you could fit in
never [62]

Answer:

If you put the posters in the box diagonally from bottom corner to the top corner.  It will fit a poster 26 in long.  

x = SqRoot (24^2 + 12^2)= 26.83 in

One one will fit because it has to go right into each of the corners to fit in the box.

Answer:


Step-by-step explanation:

I'm guessing you want a graph? I can't give you one, but I can help you make one.

To find intercepts, plug in zero for the opposite variable. So:

y-int: y=(1/5)0-6

        y=-6. The y-int point is (0,-6)

x-int: 0=(1/5)x-6

        6=(1/5)x

       30=x. The x-int point is (30, 0)

Also, the slope is 1/5, so you go up 1, go right 5. This should help :))

Identify the segments that are parallel, if any, if ∠KCB≅∠JAC.
-Dominant- [34]

The two lines are parallel if they are at same distant, but these lines will never meet at any point.

Parallel lines do not intersect each other. These lines are equidistant from each other.

In the given angles the line CB will be parallel to line AC.

CB ≅ AC

These two lines will be equidistant from each other since they both form an equivalent angle. These lines will not intersect with each other.
