25 mg is lighter than 25 cg because mg is 0.001 g and cg is 0.01 g :)
Answer:
R80625
Step-by-step explanation:
Total Cost : 60000 + 4500 = 64500
To make 25% profit: 64500 X 1.25 = 80625
Answer:
So, this triangle PQR can be broken into two right triangles, PNQ and PNR, with legs PQ = 39, PN =15, and QN = ? and PR = 17, PN = 15, and NR =? respectively.
Let's solve for what is easier first:
Since we know that 5-15-17 is a Pythagorean triplet, we can infer that NR is 5....like I said earlier, it is a right triangle, so this guess holds true.
Here comes the interesting part:
Now, we have one part of QR, which is QN.
The other part can be solved by using the Pythagorean theorem.
It is (39^2-15^2)^(1/2)..which gives you 36, the square root of 1296, which happens to be the difference between the squares of 15 and 39.
SO, QR = QN + NR
5+36 = 41
QR = 41.
Hope this helps!

Answer:

Step-by-step explanation:
Given you will receive a penny today and the amount is tripled each day
so if we write down each day payment we get a geometric progression.
Day 1=1
Day 2=3
Day 3=9
..
the series is 1,3,9,...
it is a geometric progression with a=1 r=3
we know that the general form of nth term in a GP is t(n)=a
t(n)=1*
now we need to find the amount on 12th day by substituting n=12
we get
t(12)=
He will pay
on the 12th day .
