Answer:

1/8

Step-by-step explanation:

( 2^-1 / 2^0) ^3

First simplify inside the parentheses

We know that a^b / a^c = a^(b-c)

2^(-1-0) = 2^-1

( 2^-1 ) ^3

Then we know that a power to a power is

a^b^c = a^(b*c)

2^(-1  *3)

2^ -3

Then a negative exponent makes it a fraction

a^ -b = 1/a^b

1 /2^3

1/8

We can use ratios, in other words, if one part of the photo is changed x times, how many times does the other part change?

We can set up the proportion as :
width 1 : length 1 = width 2 : length 2

20 : 30 = 5 : x

We do inverse multiplication, or multiply the outer with outer and inner with inner (W1 * L2 and L1 * W2)

20*x = 30*5
20x = 150
Divide all by 10
2x = 15
Divide all by 2 to isolate x
x = 15/2
x = 7.5cm

PART 20 ! PLEASE HELP ALGABRA 1
34kurt

Answer:

B

Step-by-step explanation:

If it cost $2.05 for each hamburger that's going to be your constant.

And it says plus an additional $2,000 so you will add that after 2.05x.

And it says 13,025 is the total so that would be on the left.

13,025 = 2.05x + 2,000

I'm 100% sure

I took Honors Algebra 1 in 8th grade, so you can trust me!!!
