What is the perimeter of triangle ABC?

Mathematics
1 answer:
julia-pushkina [17]3 years ago
8 0

Answer:

18 units

Step-by-step explanation:

Using the midpoint theorem, the perimeter of the triangle formed by joining the midpoints of the original triangle is exactly half the size in perimeter

What we mean in this case is that the perimeter of BAC IS two times the perimeter of EDF

perimeter of EDF is the sum of all the sides = 2 + 4 + 3 = 9

So the perimeter of BAC is 2 * 9 = 18

A circular ice rink is being built in town. Around the ice rink, a walkway will be built. The ice rink will have a diameter of 8
Archy [21]
 so the ice rink diameter is 80 feet what mean that the radius of ice rink is 40 feet the walkway is 10 feet wide so 10+40=50 what mean that the radius and the walkway wide make 50 feet length together 
using this length area = pi*r^2 = 3,14*(50)^2 = 7850 feet squared
area of ice rink = 3,14*40^2 = 5024 feet squared 

area of the walkway = 7850-5024 = 2826 feet squared 

hope helped

A rectangular prism has a height of 4 inches and a width of 12 inches. If the prism can hold 432 cubic inches of water, what is
chubhunter [2.5K]
Given,

Height of the rectangular prism (h) = 4 inches
Width of the rectangular prism (w) = 12 inches
Since the prism can hold 432 cubic inches of water, 
Volume of the rectangular prism (V) = 432 inches³

Formula for Volume of a rectangular prism (V) is,

V = whl

I am assuming you are looking for the third side, the length (l) of the prism.

From the above formula for volume, 

Length of the prism (l) = V ÷ wh = 432 ÷ (4x12) = 432 ÷ 48 = 9 inches
