a bowl contains eight pennies, seven nickles and ten dimes. Elyse removes one coin at random from the bowl and does not replace it. she then removes a second coin at random. what is the probability that both will be nickels?

Answer:

The answer is 4√7 - 8

Step-by-step explanation:

12/√7+2

Rationalize the denominator

=12/7+2 * √7-2/√7-2

=12√7-24/7-4

=12√7-24/3

By taking common from numerator we get

=12(√7-2)/3

=4√7-8

Answer:

The answer is 4√7 - 8

Step-by-step explanation:

The quotient for 102 divided by 6 is 17.

What is Division?

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

The number being divided is called dividend and the number which divides the dividend is called divisor.

Here we have to divide 102 by 6.

The dividend is 102 and the divisor is 6.

Using the long division method, we can do the division process.

First take the first two digits of 106, which is 10.

The multiple of 10 which is closest to but less than 10 is 6 itself.

6 = 1 × 6

The first digit of the quotient is 1.

Remainder is 10 - 6 = 4

Since 4 is less than 6, take the next digit of the dividend, 2 to 4, which gives the number 42.

42 = 7 × 6

So the next digit of the quotient is 7.

Remainder is 42 - 42 = 0.

Hence the quotient is 17.

Answer:

1980

Step-by-step explanation:

13 sides

Number of sides n=13

The sum of interior angles of polygon =(2n−4)×90°

=(2×13−4)×90°

=(26−4)×90°

=22×90°

We get,

=1980°
