Answer:
The surface area is 7600
I would really appreciate brainliest!
Step-by-step explanation:
L=Ph
L=(40x2 50x2) 20
L=3600
S= L+2B
S=3600 +2(40x50)
S= 3600+4000
S= 7600
Answer:
31.25
Step-by-step explanation:
Firstly, we need to identify the pattern.
Pattern: every next number is obtained by dividing the previous number by 2.
1st number = 1000
2nd number = 1000/2 = 500
3rd number = 500/2 = 250
4th number = 250/2 = 125
5th number = 125/2 = 62.5
6th number = 62.5/ 2 = 31.25.

It can be also solved using concept of geometric progression
In GP
any nth number is given by = 
where a is first number
r is the common ratio for the gp
r common ratio is calculated by = nth/(n-1)th
here r = 500/1000 = 1/2
a = 1000
next term which we need to find is 6th terms
Thus, 6th terms = 

=1000/32 = 31.25
Answer: C = b-(d/a)
Step-by-step explanation:
Given, a(b-c) = d
or, b-c = d/a
or, -c =(d/a)-b
or, c = b-(d/a)
