Answer:

You had to pay $30.69 after the sales tax factored in.

Step-by-step explanation:

First step is to find 7% of $28.68.

The answer to that is the sales tax, therefore making the sales tax $2.01.

Finally, you have to add $2.01 to $28.68 to get a total of $30.69, your final answer.

Write three numbers greater than 20 that have 9 as a factor

Lubov Fominskaja [6]

We just need to find the multiples of 9 that are greater than 20.

9*1 = 9
9*2 = 18
9*3 = 27
9*4 = 36
9*5 = 45

We can use 27,36, 45, .....
Your final answer should be any multiple of nine greater than 20. I recommend using 27, 36, and 45. Hope this helps!

h=20w

in one week hector works 20 hours

in two hector works 40 etc

h = hours and w = weeks. the money is just extra information.

h=20w works because if it has been two weeks we substitute the w with the number 2 and can solve

h=20(2)

h=20x2

h=40

This proves that the equation is true

A coin is tossed 8 times. Which of the following represents the probability of the coin landing on heads all 8 times?

ElenaW [278]

Answer:

$\large\boxed{\large\boxed{Probability=1/256\approx 0.0039}}$

Explanation:

Since, there are two possible outcomes for every toss (head or tail), the sample space for a coin tossed 8 times is 2×2×2×2×2×2×2×2 = 2⁸ = 256.

Landing on heads all 8 times is just one of the possible outcomes: HHHHHHHH ⇒ 1.

Hence, the probability is calculated from its own definition:

Probability = number of favorable outcomes / number of possible outcomes

$Probability=1/256\approx 0.0039\text{ }\leftarrow answer$
