Answer: 1,\ 49x^2,\ 81x^6


Step-by-step explanation:

The given monomials are 1,\24,\ 66x,\ 49x^2,\ 100x^3,\ 81x^6

1 is a perfect square .

24 is not a perfect square.

In 66x, 66 is not a perfect square.

In 49x^2, 49 is a square of 7 and power of x is 2 , so it is a perfect square monomial.

49x^2=(7x)^2

In 100x^3, 100 is a square but power of x is 3 , so it is not a perfect square monomial.

In 81x^6, 81 is a square of 9and power of x is 6 (multiple of 2) , so it is a perfect square monomial.

81x^6=(9x^3)^2

Work Rate One worker can complete a task in h hours while a second can complete the task in 3h hours. Show that by working toget
Sliva [168]

Answer: t = (3/4)h hours.

Therefore, it takes both of them (3/4)h hours to complete the task.

Step-by-step explanation:

Let

t1 represent the time taken for the one worker to complete a task.

t2 represent the time taken for the second worker to complete a task

And t represent the time taken for both.

t1 = h

t2 = 3h

Let x represent the task.

x = rate × time

r1,r2 and r are the rates at which first, second and both worker works

x = r1(t1). .....1

x = r2(t2). ....2

x = r(t) ....3

And,

r = r1 + r2. ( Rate of both equals sum of rates of the two)

From eqn 1 and 2

r1 = x/t1 = x/h

r2 = x/t2 = x/3h

r = r1 + r2 = x/h + x/3h = 4x/3h

Substituting r = 4x/3h into equation 3

x= r(t)

x = (4x/3h)t

Making t the subject of formula

t = x/(4x/3h)

t = 1/(4/3h)

t = 3h/4

t = (3/4)h hours.

Therefore, it takes both of them (3/4)h hours to complete the task.

You need to put your reindeer, Ezekiel, Lancer, Rudy, and Jebediah, in a single-file line to pull your sleigh. However, Jebediah
Korvikt [17]

Answer:

Well to start out you have 5 reindeer. If you glue Lancer and Ezekiel together you only have 4 units to arrange in different orders. That number is 24. But for each of those, Lancer and Ezekiel can be arranged in two ways... with Lancer in front of the pair or in the back of the pair. So altogether there are 48 ways to arrange the five reindeer with Lancer and Ezekiel always being together.

\frac{5w}{8} = 15

Multiply both sides by 8.

5w = 15 × 8

     = 120

Find w.

w = 120 ÷ 5

w = 24
