If you want the area of the entire trapeziod.
The formula for area of a trapeziod is:
1/2h(b₁+b₂)
So the equation applied to the trapeziod is:
2.5(20+12)
20+12 is 32. 32 multiplied by 2.5 is 80.

Answer:
96 and 288
Step-by-step explanation:
So, we need to find 2 numbers such that their sum is 8 and they do not have common factor (Relatively prime). Both these numbers will be divisible by 48 but there would be no other common divisor (after dividing by 48).
Such order independent pairs are (1,7) and (3,5).
Difference between them would be (7–1)*48=6*48 and (5–3)*48=2*48 respectively.
The differences are 6*48=288 and 2*48=96.
We have found difference without finding numbers.
Ans.: 96 and 288
p.s.: The number pairs (again order neutral) would be (48, 336) and (144, 240)
Difference for 48 and 336 add up to 384, their HCF is 48. These two numbers match the conditions. Their difference is 288.
Difference of 144 and 240 add up to 384, their HFC is 48 (the numbers are 48*3 and 48*5, common factor is 48 and no other common factor for 3 and 5; 48 is HCF). The difference is 96.
There are a total of 36 possibilities, and out of those 5 would give you a sum of 8. Therefore the probability is 5/36
Answer:
Step-by-step explanation:
12.5= 25/2
Ln (25/2).. change decimal to fraction
Ln ((5^2)/2)...change 25 to 5^2
(2ln 5)/2... log rule.. move exponent to the front
Ln 5 .. . Simplify the top and bottom 2's
Here we are supposed to turn 5 into fraction.
as we know the fraction is written in the form of p/q
So we can write
Hence fraction =
