Answer:

(y²)³ = y⁶

Step-by-step explanation:

The power of a power rule is generally shows expressions where a power is being raised by another power. In such expressions, the exponents are multiplied together and the base is kept the same, like:

[tex] \qquad \qquad\boxed{ \sf{ { {(x}^{m}) }^{n} = {x}^{mn} }}[/tex]

In order to write the expression (y²)³ in the form of yⁿ, you may use this rule (power of a power rule) to obtain the answer.

[tex]\qquad \quad \sf{ { {(y}^{2}) }^{3} = {y}^{2(3)} = \pmb {\red{ {y}^{6}}}}[/tex]

Answer:

Answer:

3

Step-by-step explanation:

So first, plugin y to your equation, it should look like this: 4x+x+5+20. Now, we can solve this. Next, we have two x's so we can combine them. The equation will now look like this: 5x+5=20. Now, we have an extra 5 laying around that we need to get rid of, so we can subtract that 5 to both sides of the equation and we get this: 5x-5=20-5 which ends up being 5x=15. Now, we just divide both ides by 5 and since 15 divided by 5 is 3, we get: x=3

Answer:

A goes with the sum of a number and 3

B goes with the product of 4 and a number

C goes with 2 less than a number

D goes with the quotient of 5 divided by a number

Answer:

answer ix c becauze the opposite angle is 48

Answer:

256 ft

Step-by-step explanation:

Assuming f(t)=(1/4)√h, we can solve for h by setting 4=(1/4)√h.

4=(1/4)√h

16=√h

h= 16^2 =256 ft

Step-by-step explanation:

h = (4 ÷ ¼)²

h = (4 × 4)²

h = 16² = 256ft

Answer:

1, 2, 17, 34

Step-by-step explanation:

1 x 34 = 34

2 x 17 = 34

Answer:

Well 34 can be divided by anything...

Step-by-step explanation:

34/1 = 34

34/2 = 17

34/3 = 11.3333

34/4 = 8.5

34/5 = 6.8

34/6 = 5.6666

34/7 = 4.857...

34/8 = 4.25

34/9 = 3.7777

34/10 = 3.4

Answer: is 4.5

Step-by-step explanation:

3k+7k-2=6k+16

3k+7k = 10k

10k-2=6k+16

-6k     -6k

4k-2=16

   +2  +2

4k= 18

= therefore the answer is 4.5

Answer: 18.4 ft

Step-by-step explanation:

Area= L x W

230= 12.5 x L (Divide both sides by 12.5 to get L)

L= 18.4 ft

Answer:

The length of the room is 18 2/5 feet.

Step-by-step explanation:

The formula for finding the area of rectangles is A = l · w

Since the area and width is given to you, we can substitute that in the formula:

230 = l · 12 1/2

Now we convert the 12 1/2 to an improper fraction so it is easier to solve.

Here's how you convert a mixed number to an improper fraction:

12 · 2 = 24

24 + 1 = 25

and put 25 over the original denominator

     = 25/2

Now you can add that to the equation...

l · 25/2 = 230 (I put 230 on the right side because that is how I am used to solving equations, but you can leave it on the right side as well. It is up to you)

To get rid of fractions, multiply by the reciprocal (Basically you flip the fraction so that the numerator becomes the denominator and the denominator becomes the numerator) on both sides

25/2 · 2/25 cancels itself out

   and

230/1 · 2/25...

   230 · 2 = 460

   1  · 25 = 25

So you would get 460/25

Thus, we end up with:

l = 460/25

Divide 460 by 25 and you get 18.4...

Technically 18.4 is the answer but in decimal form.

If you want it in fraction form, just take 0.4 and put it over 10 because 0.4 is in the tenths place. 4/10 simplifies down to 2/5...

Therefore, the answer is 18 2/5 feet.

Answer:

60 people are in the team altogether

Answer:

60

Step-by-step explanation:

to find the percentage of girls on the swim team, you would multiply a number by 30 percent. to find the number in all, you would divide 18 by 30 percent

18/0.3 = 60

there are sixty people on the swimming team
