Answer:

Product of 3y^-4 and 2y^-4 is 6y^-8

Step-by-step explanation:

Given,

3y^-4 and 2y^-4

Product of 3y^-4 and 2y^-4

i.e 3y^-4 * 2y^-4

or 3*2*y^(-4-4)

or 6y^-8

Hence we get product of 3y^-4 and 2y^-4 is 6y^-8

Answer:

y = 23

x = -4.5

Step-by-step explanation:

Given:

Equation

8x + y = -13 ......eq1

8x + 2y = 10........eq2

Find:

Solution

Computation:

Eq2 - Eq1

y = 23

From eq1

8x + y = -13

8x + 23 = -13

8x = -36

x = -4.5

Are there any prime numbers that are also square numbers

cestrela7 [59]

The definition of a prime number is one in which there are no factors other than 1 and itself. For example, 5 has no other factors other than 1 and 5 (itself).

The number 1 is not considered prime nor composite.So, even though it is a square (1²), it is not a prime number.

All square numbers have a square root that is neither 1 nor itself: 16 is the square of 4, 49 the square of 7, and so on.

Due to the fact that square numbers have factors other than 1 and itself, square numbers are not prime.

Hope this helps! :)

nickel has an approximate diameter of 20 mm and an approximate thickness of 2 mm what is the approximate volume of a stack of 40

ziro4ka [17]

Answer:

The approximate volume of a stack of 40 nickels is 25132.741 cubic milimeters.

Step-by-step explanation:

A nickel can be modelled by the formula of a right cylinder, the approximate volume of the stack of nickels ( $V_{net}$ ), measured in cubic milimeters, is the product of the number of elements ( $n$ ), no unit, and the volume of each element ( $V$ ), measured in cubic milimeters. That is:
