Hey!

Let's see... if they walk 10 feet in 6 seconds, then they walk about half a foot a second (0.6 to be exact.)

Multiply 0.6 by 45 and your answer should be.. 27. So, they walk 27 feet in 45 seconds.

Next, we keep multiplying 0.6 by a number over 45, but under 100, and the total amount of time it takes for a penguin to was 45 feet is... 75!

We know this because 75x0.6 is 45. and 75 is the number of seconds it takes to walk 45 feet for the penguin.

Your answer for #1 is 27

Your answer for #2 is 75

1. 45/6 = 7.5
7.5*10 = 75
So the penguin walks 75 ft in 45 seconds.

2. 45/10 = 4.5
4.5*6 = 27
The penguin takes 27 seconds to walk 45 ft.

11111nata11111 [884]

Answer:

She earned 1,076 dollars and 25 cents.

Step-by-step explanation:

x = 7.25 * 4,500 / 100

x = 7.25 * 45

x = 326.25

So commission earned is 326.25 $

We need to add this to her base salary for the week, so:

750 + 326.25 = 1, 076.25

Therefore she earned 1,076 dollars and 25 cents.

Hopes this helps ;p

Anyone know the answer to to this algebra question?

liraira [26]

Answer:

a=1

b= 1/16

c= 1/256

d= 1

e= 4/9

f= 16/81

Step-by-step explanation:

Plug in the values of X on the left side of the table into the function on the right side of the table. Remember that negative exponents mean the number is under a fraction. 4^-0 is like saying one over 4^0.

For the blue table, because the numbers are already in a fraction and in parentheses, you apply the exponent to each number individually.
