12) Jennifer earns $78 per day working at a supermarket. She spends $8 each day at lunch and her gas to get to and from work is $6 per day. How much money will she earn in 28 days?

Answers

So, first let’s see how much income she makes in 28 days. To do this we multiply 78$ by 28, which gives us 2184. Now we need to calculate the total of her expenses, how much money she spends. She spends 8 dollars per day at lunch, and 6 dollars per day to and from work. So let’s add 8 plus 6, and we get 14. Now let’s multiply 14 by 28 which gives us 392. Now we subtract 2184 minus 392, and we get 1792. So our answer is 1792$

Answer:

$1792

Step-by-step explanation:

$78 x 28 = 2184

28 x $8 = 224

28 x $6 = 168

168 + 224 = 392

2184 - 392 = $1792

Check Work:

1792 + 392 = 2184

2184 / 78 or 2184 / 28

=78

What is exponential growth factor?

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is and exponential growth equation

where x marks the temperature and y marks the number of people on the bench

From the graph , we can see that

As the temperature increases , the number of people at the bench increases

Hence , the exponential equation is solved

Groundhog's Day is on February 2nd each year. On this day, in Punxsatawney, Pennsylvania, thousands of onlookers watch to see if Phil, the groundhog, will cast a shadow. If he does, then six more weeks of winter are predicted. If he doesn't, then an early spring is predicted. Historically, Phil's prediction has only been correct about 40% of the time.

Using complete sentences, design a simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years. Make sure to explain how you would use the simulation to determine the probability.

Answers

A simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years is given as follows:

Choose three numbers with replacement from the set of 0 to 9, which:

numbers from 0 to 3 representing that Phil is correct.numbers from 4 to 9 represents that Phil is incorrect.

How to calculate a probability?

The parameters that are needed to calculate a probability are given as follows:

Number of desired outcomes in the context of a problem/experiment.Number of total outcomes in the context of a problem/experiment.

Then the probability is calculated as the division of the number of desired outcomes by the number of total outcomes.

The probability of a success on a single trial is given as follows:

40% = 0.4, as Phil is correct 40% of the time.

Hence the simulation needs to have three trials, each with a 0.4 = 40% probability of a success.

Find the area of the hexagon

Answers

Answer:

The area is 78 square inches

Step-by-step explanation:

so you can split the hexagon into two trapezoids, and then find the area of one of those trapezoids, which is what I did. The area of a trapezoid I think is

a, b=base, h=height

A=a+b/2*h

is a really bad way of saying it, but that's how I know to do it.

So anyways I just substituted the numbers with their corresponding letters and solved. So the area of one trapezoid was 39, and since we have two 39's, you do 39*2 and you get 78.

Hope I helped

The distance between R and S on the coordinate grid is ___ units. (Input whole numbers only.)

Answer:

The answer is 40.

Step-by-step explanation:

First you find the coordinates of both r and s. The coordinates are R coordinates. (-20 1/2 , 5) S coordinates (20,5). Since we have that written down next we have to add both -20 and 20. Before adding them you have to switch -20 to positive 20. Now you have 20 + 20. giving you 40. Since it says to put the whole number you put 40.
