Answer:
Volume of prism = 39 km cubed
Step-by-step explanation:
<u>IMPORTANT FORMULA: Volume of any prism = Area of base * Height </u>
<u />
In this case, <u><em>the area of the base</em></u> means <u><em>the area of the trapezoid. </em></u>
Area of trapezoid = base1+base2/2 * height
Area of trapezoid = 8+5/2 * 1.5
Area of trapezoid = 13/2 * 1.5 = 9.75
We already know that the height of the trapezoidal prism is 4 kilometers.
So, we have all of the values that are needed to correctly fill in the formula.
Volume of the prism = 9.75 * 4 = 39
Answer:
6.7
Step-by-step explanation:
Given is a right angled triangle.
So by Pythagoras theorem:
Length of the third side

55% of 79.95 is 43.972 so that is the discount amount. 79.95-43.972=35.978. 35.978 is the new price.
