Answer:
True
Step-by-step explanation:
The reciprocal of is , then
÷ -
Change ÷ to × and turn the second fraction upside down, that is
× - ← cancel 11 and 55 by 11
= × -
= - ← True
Answer:
Each friend will receive 7 candies.
Step-by-step explanation:
Given that:
Number of candies in one bag = 20 pieces
Number of candies in other bag = 15 pieces
Total number of candies = 20 + 15 = 35 pieces
Number of friends = 5
Let,
c be the number of candies each friend will receive.
5c = 35
Dividing both sides by 5
c = 7
Hence,
Each friend will receive 7 candies.
Answer:
140 deg
Step-by-step explanation:
The sum of the measures of the interior angles of an n-gon is
(n - 2)180
In a 9-gon, there are 9 sides, so n = 9.
The sum of the measures of the interior angles of a 9-gon is
(n - 2)180 =
= (9 - 2)(180)
= 7(180)
= 1260
A regular polygon has congruent interior angles. A 9-gon has 9 congruent interior angles. The measure of each interior angle is the sum of the measures of the interior angles divided by the number of angles.
1260/9 = 140
Answer:
A. 38 degrees
Step-by-step explanation:
That entire angle is supplementary meaning it will add up to 180 degrees. So we are given 52 and 90 because of the right angle. Those together come to 142 then subtract that from 180 and get 38 degrees.
