Answer:
It will be at 33.3333 repeating so if you estimate the answer is y = 33

What ? enter a image Im confused reading this .
but anyways have a good day :)
Equilateral triangle is a triangle in which all its sides are equal.
Given:
side = 10 cm
Area of an equilateral triangle = √3/4 a²
1st: a = 10 ; A = 43.3 cm²
2nd: a = 5 ; A = 10.83 cm²
3rd: a = 2.5 ; A = 2.71 cm²
4th: a = 1.25 ; A = 0.68 cm²
5th: a = 0.625 ; A = 0.17 cm²
6th: a = 0.3125; A = 0.042 cm²
7th: a = 0.15625; A = 0.011.cm²
Summation: a1/1 -r ; a1 = 43.30 ; r = 0.25
43.30 / 1 - 0.25 = 43.30/0.75 = 57.73 cm²
The sum of the areas of the triangles if the process is continued without end is 57.73 cm²
Answer:
the length is double the number of months.
Step-by-step explanation:
Option C:
Lateral area of the prism = 160 m²
Surface area of the prism = 288 m²
Solution:
Given data:
Length of the prism = 16 m
Width of the prism = 4 m
Height of the prism = 4 m
Lateral area of the prism = perimeter of the base × height
= 2(l + w) × h
= 2(16 + 4) × 4
= 2(20) × 4
= 160
Lateral area of the prism = 160 m²
Surface area of the prism = Lateral area + 2<em>lw</em>
= 160 + 2(16 × 4)
= 160 + 128
= 288
Surface area of the prism = 288 m²
Hence option C is the correct answer.
Lateral area of the prism = 160 m²
Surface area of the prism = 288 m²
