Work at a convenience store 60% of your time, and earn $11.00 an hour. Referee games at your city park 25% of your time, and earn $19.00 an hour. Do your elderly neighbor’s housework 15% of your time, and earn $16.00 an hour. What will your average hourly wage be? Enter your answer up to two decimal places.

Answers

Answer:

13.75

Step-by-step explanation:

The expected value of the hourly wage is the sum of the probabilities (percentage of time spent on each job) multiplied by the payoff (money earned) from each possible occurrence (job):

(0.6 × 11) + (0.25 × 19) + (0.15 × 16) = $13.75.

7e = f
What does it mean when a letter and number are together like this

Answers

Answer:

multiplication

Step-by-step explanation:

7 x e = f

Answer:

If a number and letter are together, it means it is a multiplication problem. It is the same thing as 7 x e.

Step-by-step explanation:

We don't know what e is because there isn't a number given to us to solve the problem, so we say 7 x e = 7e, but the equation tells us that 7e = f, so 7 x e is equal to f which means 7e is equal to f.

Let me just give a number to e. Let's say e is 5

7e = f

We already know 7e is the same thing as 7 x e, so let's rewrite it

7 x e = f

We will change e to 5 and multiply the numbers together

7 x 5 = f

Now multiply 7 x 5

35 = f

If 35 is equal to f, that means the value of f is 35, so f = 35 ( I don't know if this makes sense lol)

But let's now take the original equation and assume f is 42

7e = f

Remember, 7e is 7 x e, so rewrite your equation

7 x e = f

Now we will change the f to 42

7 x e = 42

To get e, we will have to think about what multiplies by 7 to get 42. We will have to change this to division. We will divide 42 by 7

42÷7 = 6

That means e is 6. Now let's write the equation with changing e to 6

7 x 6 = 42

7 times 6 is 42, so we will multiply that

42 = 42

Now we have equal answers. Of course, 42 is equal to 42

Overall I'm trying to say 7e = f

I'll solve this again, so you won't have to go back up.

7e = f

7 x e = f

f = f

I hope this makes sense lol

On Monday Sylvia spent 5/12 of a day driving to her cousins house. On Friday she spent the same amount of time driving home. What fraction of a day did Sylvia spend driving to her cousins house and back?

Answers

Answer: The fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]

Step-by-step explanation:

Given: Fraction of day Sylvia spent to drive her cousins home = [tex]\dfrac5{12}[/tex]

Fraction of day Sylvia spent to drive her home back= [tex]\dfrac5{12}[/tex]

Total fraction of day Sylvia spend driving to her cousins house and back = [tex]\dfrac5{12}+\dfrac{5}{12}[/tex]

[tex]=\dfrac{5+5}{12}\\\\=\dfrac{10}{12}\\\\=\dfrac{5}{6}[/tex]

Hence, the fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]

Answer:

y = -4

x = 3

Step-by-step explanation:

I will be using the elimination method to solve this:

Begin by times -1 to the bottom equation.

[tex]2x-3y=18[/tex]

[tex]-2x-y=-2[/tex]

Add them together

[tex]0x-4y=16[/tex]

ignore the 0x and divide -4 to both sides

[tex]\frac{-4y}{-4} =\frac{16}{-4}[/tex]

y = -4

Plug y back into one of the two original equations

[tex]2x-3(-4)=18[/tex]

multiply -3 and -4 to get +12

[tex]2x+12=18[/tex]

subtract 12 to both sides

[tex]2x=6[/tex]

divide by 2 to both sides

x = 3

150°+5x=180°

5x=180°-150°

5x=30

x=30/5

Answer:

x = 6

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

5x + 13 + 104 + 33 = 180, that is

5x + 150 = 180 ( subtract 150 from both sides )

5x = 30 ( divide both sides by 5 )

x = 6

Please Help !! (no fake answers please)

Answers

Answer:

$80

Step-by-step explanation:

Substitute x for 40 in both equations. Let's start with 50 + 12x. The equation becomes 50 + 12(40). First, multiply 12 by 40 to get 480. Now add 480 to 50 to get a total of $530 in printing fees for Company A.

Now, let's move on to 10 + 15x. That becomes 10 + 15(40). First, multiply 15 by 40 to get 600. Then add 10 to 600 to get $610 in printing fees for Company B.

Now that we know the total costs, let's subtract them to get our difference. Simply subtract 530 from 610 to get our final answer: an $80 difference in printing fee costs between the companies.

Find the value of X and Y

Answers

Answer:

x = 30

y = 5

Step-by-step explanation:

Because the top triangle shows 3 congruent angles, we know it's an equilateral.

Therefore 8y = 40

y = 5

______________

Now we have two sides of the triangle: 40 and 80.

The lower left angle of the whole triangle must be 90 degrees because if the hypotenuse is twice the adjacent side, it must be a 30-60-90 triangle.

So, the larger angle containing angle x must be 90 degrees. And because we know that the adjacent angle (equilateral triangle) is 60 degrees, angle x must be 30.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Point(-5, -7).

Here, x= -5 and y= -7

So, r = √x² + y²

r= √(-5)²  + (-7)²

r= √25 + 49

r = √74

r= 8.6

So, sec θ= H/ B

              = r/x

              = 8.6/ (-5)

Answers

Answer:

The equation required to find the volume of concrete is:

L X W X H.

Step-by-step explanation:

L = Lenght

W = Width

H = Height

To calculate the required volume for concrete, you'd need to multiply the measures of all the dimensions together such as the lenght and the breath (which gives you the Area) and the thickness or height of the staircase.

If the calculation is being expressed in Feet, the answer will also be expressed as Volume of concrete in Cubic feet.

Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it.

At the end of the 4 years, how much interest in dollars and cents did the account earn?

Answers

Answer:

$1105

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 6500 × 0.0425 × 4 = 1105

I = $ 1,105.00

The simple interest accumulated

on a principal of $ 6,500.00

at a rate of 4.25% per year

for 4 years is $ 1,105.00.
