Answer:

Step-by-step explanation:

Lila made a triangular flag to cheer on her favorite sports team. The perimeter of the flag is 20 inches.

A triangular flag is shown. 2 sides have lengths of 8 inches. The total perimeter of the flag is 20 inches.

Heron’s formula: Area = StartRoot s (s minus a) (s minus b) (s minus c) EndRoot

Approximately how many square inches of fabric were used to make the triangular flag?  

15 square inches

76 square inches

186 square inches

215 square inches

Given that we have an outside border of 20 inches and 2 sides are 8 inches each, the third side is equal to 4 inches. Solving for s which is the semi outside border ,                                                   S = 20/2 = 10

Using Heron’s formula,

A = sqrt of  (10)(10-8)(10-8)(10-4) = 15.49 in2

The height of a cone-shaped container is 15 centimeters and its radius is 14 centimeters. Kate fills the container completely wi
lesantik [10]
The volume of the cone with radius r=14 cm and height h=15 cm is,
V= \frac{1}{3}  \pi r^2h =  \frac{1}{3}  \pi *14^2*15 = 3077.2~cm^3

Each day 40 cm^3 is subtracted from the volume. So the volume of honey left after [d] number of days would be the starting volume minus 40 times number of days passed.
V left=V start-40*d
V left = 3077.2 - 40d

It asks when the volume will be empty, The volume left is zero after how many days?
0 = 3077.2 - 40d
d=76.93 days,  or 80 days rounding to whole numbers.
