Answer:1 divided by 9/13=1.4,1 2/5 divided by 1 13/15=13/2,1 2/3 x 2 1/10=1/1
Step-by-step explanation:
Answer:
Step-by-step explanation:
volume =1/3×base area×height
216=1/3× A×6
base area=216/2=108 in²
From the explicit formula:
an=3+(n-1)8
simplifying this we get:
an=3+8n-8
an=8n-5
thus
the recursive formula is:
an=an-1+
the missing part is the common difference which is 8
Answer:
1. 144⁰
2. 60⁰
Step-by-step explanation:
The formula to find the measure of the interior angles of a regular polygon is:
m< = (n - 2) • 180/n where n = the number of sides
For a decagon, there are 10 sides.
m< = (10-2) • 180/10 = 144°
A regular polygon/equilateral triangle is defined as having equal sides and angles.
