A number to the 0 power is 1, so your answer is correct.

y to the 4th power is equal to A because when you combine the two, you add their exponents.

It is also equal to B. y to the 6th power divided by y to the 4th power because when you divide two exponents, you just subtract. So that means it is equal to D.

Rearrange the numerators and denominators in the first five fractions shown to create five new fractions that are equivalent to

hichkok12 [17]

To identify equivalent fractions we must check them by performing the operation (division) or cross products, if the result is the same they are equivalent fractions.

<h3>What are equivalent fractions?</h3>

Equivalent fractions are a mathematical term to refer to those fractions that represent the same quantity even though the numerator and denominator are different.

<h3>How do we know if two fractions are equivalent?</h3>

Two fractions are equivalent if the products of the numerator of one and the denominator of the other are equal, that is, cross products.

Let's see an example:

Let us check if $\frac{2}{5}$ and $\frac{4}{10}$ are equivalent.

To do this, we multiply the numerator of one of the fractions by the denominator of the other, as shown below:

2 x 10 = 20

5 x 4 = 20

Since the result is the same, we can say that the fractions are equivalent.

Note: This question is incomplete because there is some information missing. However I can answer it based on my general prior knowledge.

How to answer this? A farmer had 455 ducks and chickens. He sold 2/5 of the ducks and bought another 104 chickens. As a result,

julia-pushkina [17]

Answer:

(a) 25

(b) $4816

Step-by-step explanation:

Let's say the starting amount of ducks is d, and the starting amount of chickens is c. Since there are only ducks and chickens, we can say that d + c= 455.

Next, the farmer sells 2/5 of the ducks, so we subtract 2/5 of the ducks so that the ending duck amount is d - (2/5)d = (3/5) d

After that, the farmer buys another 104 chickens, so we add 104 chickens to the current amount of chickens to get the ending chicken number as 104+c

Given the ending duck and chicken count, we can say that the ending farm animal count (we can represent this as a) is (3/5)d + 104 + c = a

The number of ducks is 2/3 the total number of animals at the end, so (3/5)d = (2/3)a

Let's list our equations out so it is easier to solve:

d+c = 455

(3/5)d + 104 + c = a

(3/5)d = (2/3)a

We have three equations and need to solve for three variables. One common variable in all three equations is d, so it might help if we put everything in terms of d.

Starting with d+c=455, if we subtract d from both sides, we get c=455-d. We can substitute this in the second equation to get

(3/5)d + 104 + 455 - d = a

-(2/5)d + 559 = a

(3/5)d = (2/3)a

Next, we can substitute for a. If we multiply both sides by 3 and then divide by 2 in (3/5)d = (2/3)a , we get

(9/10)d = a

Substitute that in to the second equation to get

-(2/5)d + 559 = (9/10) d

-(4/10)d + 559 = (9/10) d

add (4/10)d to both sides to isolate the variable and its coefficient

(13/10)d = 559

multiply both sides by (10/13) to isolate the coefficient

d = 430

Therefore, the starting number of ducks is 430 and the starting amount of chickens is 455-430 = 25

For (b), 2/5ths of the ducks are sold, so this is (430) * (2/5) = 172. Each duck is sold for 28 dollars, so this is 172*28=$4816 as the total price
