Answer: Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. The formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.?
Step-by-step explanation:
Part A:
For the parallelograms it is shape 5.
For the rectangles it is the shapes 1 and 3
For other it is the shapes 2 and 4
Part B:
It would have the shapes 1, 3 and 5.
Part C:
All quadrilaterals are not parallelograms because some quadrilaterals do not have any congruent sides
The absolute value is always non-negative.
Answer:
69.6 miles per hour
Step-by-step explanation:
Length of the skid marks = 242 feet
The formula used for the velocity is
where, L is the length of skid marks in feet and the velocity obtain has the units of miles per hour.
By substituting the value
v = 69.6 miles per hour
Thus, the speed of the car at the time of accident is 69.6 miles per hour.
