½×10×8.2 explain with answer
Answers
Take 10 * 8.2 (Easier this way)
You get 82.
Take 82 *1/2 (or divide by 2)
You get 41.
Answer:
41
Step-by-step explanation:
1/2 x 10 x 8.2
We will convert the decimal to fraction first
1/2 x 10 x 41/5
Then we will reduce the numbers with the greatest common factor (5)
5 x 41/5
We will remove the fives since they are the common factors
And we will remain with the answer 41
An auditorium has 21 rows of seats. The first row has 18 seats and each succeeding row has 2 more seats than the previous row. How many seats are in the auditorium?
Answers
Answer:
798
Step-by-step explanation:
So, 21*{2*18 + (21-1)*2}/2
= 21*{36 + 20*2}/2
= 21*{36+40}/2
= 21*76/2
= 1596/2
= 798
Total number of seats is 798
Given that;Number of seats in first row = 18
Number of rows = 21
Each row added number of seats then previous = 2
Find:Total number of seats
Computation:Total number of seats = Sn = (n/2)[2a + (n-1)d]
Total number of seats = Sn = (21/2)[2(18) + (21-1)2]
Total number of seats = (21/2)[36 + (20)2]
Total number of seats = (21/2)[36 + 40]
Total number of seats = (21/2)[76]
Total number of seats = (21)(38)
Total number of seats = 798
