Answer:

The wood for 7.50!

Step-by-step explanation:

You are trying to find the unit rate in this situation!

It's simple, Cost ÷ Amount/Weight

13.65 ÷ 7 = 1.95

7.50 ÷ 5 = 1.50

Clearly, the wood for 7.50 is the better buy!

Answer:

Step-by-step explanation:

14: k^-3/k^4= 1/k^7

15: answer : 1/3²

16: n^-4

17: f-g^4 = 3-(-5)^4 = -622

18: (x^5-y^2)²+x³ =

(2^5-8^2)²+2³ =1032

19: m²-n³

6²-2³ = 36-8=28

20 : 2²×3²×5³= 4500

4500/10 = 450 islands

Simplify ten to the eighth divided by ten to the negative third.
In-s [12.5K]

Answer:

10^{11}

Step-by-step explanation:

A statement is given i.e. "ten to the eighth divided by ten to the negative third."

It means that 10 to power 8 divided by 10 to the power -3.

Mathematically,

\dfrac{10^8}{10^{-3}}

We know that, \dfrac{x^a}{x^b}=x^{a-b}

Here, x = 10, a = 8 and b = -3

So,

\dfrac{10^8}{10^{-3}}=10^{8-(-3)}\\\\=10^{8+3}\\\\=10^{11}

So, the answer is 10^{11}

Which coordinate pair fits the set of coordinates {(0, 4), (-2, 1), (-4, -2)} defined by a linearfunction?
dedylja [7]

Answer:

y = 1.5x + 4

Step-by-step explanation:

Slope = (y2-y2)/(x2-x1)

= (1-4)/(-2-0) = -3/-2 = 3/2

y = (3/2)x + c

When x=0, y=4 (y-intercept is 4)

y = (3/2)x + 4

y = 1.5x + 4

Evaluate the expression below when x= -2
KatRina [158]

Answer: -1

Step-by-step explanation: To evaluate this problem, the first thing we want to do is plug in the appropriate value for <em>x</em>.

When we do that, we get \frac{(-2)^2- 8}{-2 + 6}

A good rule of thumb for problems that involve division bars is to simplify what's above the division bar as much as you can and what's below the division bar as much as you can before you do your dividing.

So up top if we follow our order of operations, the first thing we want to do is square the -2 before we subtract. So -2² is +4.

So in our numerator we have 4 - 8.

Down below, we have -2 + 6 which is +4.

4 - 8 is -4 and -2 + 6 is +4.

So we have \frac{-4}{+4} which reduces to -1.
