Find the value of y when x=9.
y=1- 2x

Answer: This is a CRQ so you will want to answer using R.A.C.E

Step-by-step explanation:

First, restate the question: "If employees work exactly 40 hours the job with the higher pay rate is..."

Now let's figure it out who gets paid more. The hourly employee gets $18 per hour, for 40 hours each week... 18 times 40. That's $720 for each week.

But they don't work for just one week, they have to work the whole year! So that's 52 weeks. Take the $720 and multiply by 52 weeks.

Now you have the total for how much hourly guy will make in a whole year.

Compare this number with the salary guy who is making $38,000 per year. Which person get's paid more? Hourly or Salary? Don't forget to include your calculations!

.............................................................................

Next part of the question: "When graphed as a line..." This part of the question you do not have to do because we did not cover slope of a line yet. (Hi, I'm your math teacher by the way lol)

.............................................................................

Next part of the question adds 10 hours of overtime to their work week. This changes everything! Remember, the salary guy gets $38,000 every year, no matter how many hours of overtime he works.

However, the hourly guy gets extra money for these extra hours! For overtime, the hourly employee gets "time and a half" pay whenever he has to work extra time. This means he gets his original $18 per hour, AND now also gets half of that ($9 per hour) ... which adds up to a whopping $27 per hour for overtime (nice!)

Hourly guy works 10 extra hours per week, at $27 per hour. Multiply that and you get $270 per week. Remember, 52 weeks per year, so now take the $270 and multiply by 52 weeks. This gives you the total amount of overtime money hourly guy makes.

Combine his overtime money with his regular money (the first thing we did at the start of this problem) to get his new grand total for the year.

Salary guy still makes $38,000 per year. So now that they work overtime... who gets paid more?

Remember to answer in R.A.C.E format. Restate your question, Answer all parts of the question, Cite a math term/definition/concept that supports your answer (maybe use "hourly rate" or "salary"), and Explain your steps and thinking.

Answer:

32 m^2

Step-by-step explanation:

First find the volume of the bottom section

V = l * w*h

V = 6 * 2 * 2 = 24 m^2

Then find the volume of the top section in green

The length is 6-4 =2,  the height is 4-2, width is 2

V = = l*w*h = 2*2*2 = 8

Ad the volumes together

V = 24+8 = 32 m^2

Answer: The winning time increased by an average of 0.4 second per year from year 2 to year 4.

The winning time for a race displayed in the table would be:

C). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Find the increase in winning time:

Given that,

Year                             Winning Time(seconds)

1                                          27.5

2                                         28.4

3                                         28.7

4                                         29.2

5                                         29.44

Hence, The total change in the time is,

= (0. + 0.3 + 0.5 + 0.24)/4

= 0.485 seconds

Now, If we round off, it becomes 0.5 seconds.

Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.

Thus, ''Option C'' is the correct answer.

hope this helps, good luck :)

Answer:

A

Step-by-step explanation:

Answer:

D. (4,-1)

Step-by-step explanation:

So, we have these two equations:

2x + y = 7

x - 2y = 6

Isolate x in the second equation:

x = 2y + 6

Substitute it into the first equation:

2(2y + 6) + y = 7

4y + 12 + y = 7

5y + 12 = 7

5y = -5

y = -1

Plug y back into the second equation:

x - 2(-1) = 6

x + 2 = 6

x = 4

So, the correct answer is D. (4,-1)

Hope this helps!!

B makes sense.

On the first play, they gained 6 yards.

On the 2nd play, they lost 8 yards, which can be shown as + (-8)

On the 3rd play, they lost two yards, which can be shown as + (-2)

If you input it in a calculator, you'd find that the answer is a negative, which makes sense considering that they lost more yards than they gained.

Answer:

Step-by-step explanation:

The system of equations x + y = 1 and x – y = 2 has the unique solution x = 1 and y = –1.

There are infinite pairs of system of equations which have the unique solution x = 1 and y = –1.

Hope this information will clear your doubts about the topic.

To use the angle-angle similarity theorem you need to know 2 corresponding angles of each triangle are the same.

You are already shown that angles H and M are the same.

The sets of corresponding angles are:

H and M, N and I, and O and J

The answer would be angle O and angle J are similar.

Answer:

1.  195

2.  Y= 8t +35

Step-by-step explanation:

Answer:

$195; y=8t+35

Step-by-step explanation:

You can make an equation to find out how much Enola earns a day:

y=8t+35 ––This shows that "y" is the earnings for the day, "8t" represents $8 per table, and the "+35" represents the guarenteed $35 a day.

To answer the first question, the replace t with 20: y=8(20)+35

y=160+35

y=195

*For the second answer, I would put the equation because you do not know the number of tables because it is unspecified.

***You can change the "y" to whatever if you need to

In 1993 year his balance will hit $2300.

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, is the formula for compound interest.

Given, On April 1, 1986, Casey deposited $1150 into a savings account paying 9.6% interest, compounded quarterly.
Here the given amount = $1150

Amount after getting compound interest in this amount = $ 2300

Since, $2300 is double to the amount $1150

According to the rule of 72, an amount is doubled if the product of annual rate and period (in years) is equal to 72. Also, with the help of this rule we get the approximate value of rate or time.

Since, Here the annual rate of interest = 9.6%

Let the given amount $1150 is doubled ($2300)  in t years.

The, 9.6 × t = 72

⇒ t = 72/9.6 = 7.5

Since he deposited money on April 1 1986,

Thus, Her amount be $2300 on 1993

Therefore,  In 1993 year his balance will hit $2300.
