4 0

Answer:

Step-by-step explanation:

Using the given lengths if we say this is a right triangle then 8 would be length of hypotenuse

From the Pythagorean theorem

8^2 = 5^2 + 7^2

64 = 25 + 49

64 = 74 is not a correct equation so the triangle is not a right triangle for the given lengths

the fourth term of an arithmetic sequence is 141, and the seventh term is 132. what is the first term?

Cerrena [4.2K]

The 1st, 4th, and 7th terms make an arithmetic sequence of their own. The 4th term is the average of the 1st and 7th, so ...
(1st +7th)/2 = 4th
1st + 7th = 2×4th
1st = 2×4th - 7th

The first term is ...
2*141 - 132 = 150

Loss=C.P.-S.P.

=> Loss=400-336

=Rs.64

Loss%=Loss/C.P.×100
