Answer: Last option.

Step-by-step explanation:

The total amount of concrete in the ramp (V_t) will be the sum of the volume of the  rectangular prism (V_{rp}) and the volume of the triangular prism (V_{tp})

V_t=V_{rp}+V_{tp}

The formulas are:

V_{rp}=lwh

Where "l" is the lenght, "w" is the width and "h" is the height.

 V_{tp}=\frac{bhl}{2}

Where "l" is the lenght, "b" is the base and "h" is the height.

Substituting, we get:

V_t=V_{rp}+V_{tp}\\\\V_t=lwh+\frac{bhl}{2}\\\\V_t=(18in)(6in)(6in)+\frac{(8in)(6in)(18in)}{2}\\\\V_t=1,080in^3

I can't get the answer lol

Answer:

-7/4

Step-by-step explanation:

Recall that slope, m, is defined as the ratio rise to run:  rise/run.

Note that if we start at x = -2 (an arbitrary choice), and move 6 units to the right, we end up at x = 4.  This is the 'run.'  Simultaneously, y starts at 1 and decreases to - 6, a change of -7.  

Thus, the slope of the line through these two points is m = rise/run = -7/4

Answer:

  1. -51
  2. -30
  3. -60
  4. 2 or -2

Step-by-step explanation:

The function puts a minus sign on 3 times the magnitude of the input.

1. y = -|3×17| = -51

2. y = -|3×10| = -30

3. y = -|3×20| = -60

4. -6 = -|3x|

  2 = |x| . . . . divide by -3

  x = ±2 . . . . two possibilities

Why will percent of change always be represented by a positive number?
Murljashka [212]
Percent of change will always be positive because the change is an absolute value. As we know, absolute value is always a positive value because you don't pay attention to the direction, only the distance is important.
