Find the 60th term of the arithmetic sequence -14, -25, -36, ...

yaroslaw [1]

Answer:

here a1=-14

d=a2-a1

d=-25-(-14)

d=-25+14

d=-11

an=a1+(n-1)d

a60=-14+(60-1)(-11)

a60=-14-59(11)

a60=-14-649

1/5 part of pole is inside the mud, 2/3 part is inside the water and the remaining length of 10m is above the surface of the wat

wolverine [178]

Answer:

75 m

Step-by-step explanation:

Let the length of the pole to be : x m

1/5 of x is inside the mud, this will be : 1/5 x

2/3 of x in inside water , this will be : 2/3 x

10 m remaining is above the water surface. Finding the fraction that remains will follow;

x - {1/5 x + 2/3x } = 10

x-13/15 x =10

2/15 x = 10

x= 75 m

athletes are running a race. A gold medal is to be given to the winner, a silver medal is to be given to the second-place finish

Agata [3.3K]

Using the permutation formula, there are 157,410 ways for the medals to be distributed.

<h3>What is the permutation formula?</h3>

The number of possible permutations of x elements from a set of n elements is given by:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this problem, 3 athletes are chosen from a set of 55, hence the number of ways is given by:

P(55,3) = 55!/52! = 157,410

157,410 ways for the medals to be distributed.
