Answer:

I don't believe this is a mathematics related question....

Step-by-step explanation:

Don't have someone write this for you though, this sounds like a fun assignment. If you need help with the terms

Central plot = what is happening. Is a king trying to fight off a dragon? A penguin trying to learn to hunt?

Conflict = what goes wrong to make the goal harder.

Conclusion = How it ends.

Characters = People or creatures in the story.

Dialogue = What people are saying.

Setting = When and where the story takes place.

Answer:

Step-by-step explanation:

follow a few exponent rules and you can figure this out

when expoenents are to the power of something you can mutilply the expoents.. and when there is a minus sign in the exponent.. it's like the reciprocal $x^{-2}$ is 1/ $x^{2}$ soooo...

mutilply the -2/3 by each of the exponents in the question the 8 is tricky b/c it has an invisible 1 on it :o

= $8^{-2/3}$ $w^{-14/3}$ $x^{10/3}$ $y^{-6/3}$ $z^{18/3}$

= 1/ $\sqrt[3]{8*8}$ * 1/ $w^{14/3}$ * $x^{10/3}$ * 1/ $y^{2}$ * $z^{6}$

= 1/ $\sqrt[3]{64}$ * 1/ $w^{14/3}$ * $x^{10/3}$ * 1/ $y^{2}$ * $z^{6}$

= 1/4* 1/ $w^{14/3}$ * $x^{10/3}$ * 1/ $y^{2}$ * $z^{6}$

Brandon has a jar of quarters and dimes with a total value of $10.05. The number of quarters is 3

Hunter-Best [27]

Answer:

Brandon has 18 Dimes and 33 Quarters [Beware: The problem does not state that Brandon owns the coins - he just has them. Check your pockets]

Step-by-step explanation:

Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). I'll use pennies instead of dollars, so avoid the clutter of decimal points.

We are told that:

Q = 2D - 3 [The number of quarters is 3 less than twice the number of dimes.]

and

25Q + 10D = 1005 [total value of $10.05]

Substitute the value of Q in the first equation in the second, so that we have an equation with just one unknown, D.

25(2D-3) + 10D = 1005

50D - 75 + 10D = 1005

60D = 1080

D = 18

Q = 2D - 3

Q = 2(18) - 3

Q = 33

=============================

Check

25Q + 10D = 1005

25(33) + 10(18) = 1005 ?

825 + 180 = 1005 YES

----

Q = 2D - 3 ?

33 = 2(18) - 3 YES

The inequality x<4 in interval notation

Strike441 [17]

X<4 represents "all numbers smaller than 4, including all negative numbers."

In interval notation, this comes out to (-infinity, 4).

Point 4,6 is reflected across line y= X and then dilated by a factor of 1/2 using the origin as the center of dilation. What is

soldier1979 [14.2K]

9514 1404 393

Answer:

(3, 2)

Step-by-step explanation:

Reflection across y=x swaps the coordinates:

(x, y) ⇒ (y, x)

Dilation by a factor of 1/2 multiplies each coordinate by 1/2.

(x, y) ⇒ (x/2, y/2)

The combination of these transformations gives you ...

(x, y) ⇒ (y/2, x/2)

(4, 6) ⇒ (3, 2)
