For this case, what you must keep in mind is that the volume of a triangular prism is the product of the area of the base by height.
 We observed that:
 V = (15) * (20) = 300
 The numeric value is correct.
 However, the units are not because the volume is expressed in:
 units ^ 3
 Answer:
 "a triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 CUBIC inches. "

The horizontal line segment at the top of the polygon on the grid below is how many units long?​
Ymorist [56]

Answer:

6 units long.

Step-by-step explanation:

Given:

A polygon drawn on a graph.

In order to determine the distance of the horizontal line at the top, we find the coordinates of the end points and then use distance formula to find the exact distance.

Let us label the polygon as ABCD as shown below. AB is the length of the horizontal line.

Coordinates of A are (x_1,y_1)=(-3, 4) as seen in the graph.

Coordinates of B are (x_2,y_2)=( 3, 4) as seen in the graph.

Now, distance formula  for two points (x_1,y_1)\ and\ (x_2,y_2) is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d_{AB}=\sqrt{(3-(-3))^2+(4-4)^2}\\d_{AB}=\sqrt{(3+3)^2+0}\\d_{AB}=\sqrt{36}=6\ units

Therefore, the horizontal line at the top is 6 units long.

The dimensions of the upper part:

  • Width = 18 inches
  • Length = 14 inches / 2 = 7 inches

How many 7 digit phone numbers are there assuming the first digit can't be a 0 or a 1?
Anettt [7]
The first digit can be any one of the numbers 2-9 That a total of 8 numbers.

The next 6 digits can be any permutation of 6  from the numbers  0 to 9.
(10 numbers)

nPr  =  n! / r!

so here we have  10P6  = 10! / 6!  =  10*9*8*7  =  5040

So final answer  is 8 * 5040 = 40,320
