Answer:

Step-by-step explanation:

she worked 50.25 hours for 18.8 dollars an hour

the first 40 hours she paid regularly: 40*18.8= 752 dollars

extra time : 50.25-40=10.25

the extra time pay: 10.25 *18.80(1+0.5) = 289.05

Gross pay = 752+289.05=1041.05

Answer:

No

Step-by-step explanation:

Plug in 7.5 as t into the equation, and solve:

p = -10t + 115

p = -10(7.5) + 115

p = -75 + 115

p = 40

This means in 7.5 hours, he will still have 40 papers left to grade.

So, he will not be able to finish grading in 7.5 hours.

Given:

Endpoints of segment AB are A(- 18, 5) and B(- 4, 5).

Point Z is located exactly 1/8 of the distance from A to B.

To find:

The value of the x-coordinate of point Z.

Solution:

Point Z is located exactly 1/8 of the distance from A to B.

AZ:AB=1:8

AZ:ZB = AZ:(AB-AZ)= 1:(8-1) = 1:7

It means point Z divided segment AB in 1:7.

Using section formula, the x coordinate of point Z is

[tex]x-coordinate=\dfrac{mx_2+nx_1}{m+n}[/tex]

[tex]x-coordinate=\dfrac{1(-4)+7(-18)}{1+7}[/tex]

[tex]x-coordinate=\dfrac{-4-126}{8}[/tex]

[tex]x-coordinate=\dfrac{-130}{8}[/tex]

[tex]x-coordinate=-16.25[/tex]

Therefore, the required x-coordinate of point Z is -16.25.

Step-by-step explanation:

The equation of the number of students needed to make $1,500 in profit will be 1,500 = 5n – 300. Then the correct option is A.

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

Mustafa's soccer team is planning a school dance as a fundraiser.

The DJ charges $200 and decorations cost $100.

The team decides to charge each student $5.00 to attend the dance.

If n represents the number of students attending the dance.

The total amount of expenses will be

Total Expense = $200 + $100

Total Expense = $300

The total amount of charges will be

Total Charge = 5n

Then the amount of the profit will be

Profit = Total charge – Total expense

1,500 = 5n – 300

Then the equation can be used to find the number of students needed to make $1,500 in profit will be 1,500 = 5n – 300.

Then the correct option is A.

Answer:

The correct statements are: B and D.

Step-by-step explanation:

Standard deviation is one of the measure of dispersion or spread of a dataset from the average value of the dataset. The standard deviation measures the variability of the distribution of values.

The higher the spread or variability in the data set, the greater is the standard deviation value and thus greater will be the magnitude of the deviance of the value from their average.

Then the standard deviation (S.D.) is given by,

[tex]S.D.=\sqrt{\frac{1}{n-1}\sum\limits^{n}_{i=1} {(x_{i}-\bar x)^{2} }}[/tex]

The correct statements are:

B. It is a measure of variability.

D. It is calculated using the mean.

Answer:

5/36

Step-by-step explanation:

1 x 5= 5

and 9 x 4=36

which makes 5/36

The solution to the product of the fractions is 5/36

From the question, we have the following parameters that can be used in our computation:

1/9 x 5/4

Express 1/9 as 1/9

So, we have

1/9 x 5/4 = 1/9 x 5/4

Evaluate the products of 1 and 5

So, we have

1/9 x 5/4 = 5/9 x 1/4

Evaluate the products of 9 and 4

So, we have

1/9 x 5/4 = 5/36

Hence, the solution is 5/36

Answer:

The expression is equal to 76.

8^2 becomes 64, and 6(14 - 12) becomes 6(2), which is 12. Add 64 and 12 and you get a sum of 76.

Answer:

I believe the answer is 76

Step-by-step explanation:

Equation: 8^2 + 6 (14 – 12)

First evaluate the power: 8^2= 64

Second solve in the parentheses: (14-12) = (2)

Third solve the multiplication: 6 * 2 = 12

Finally add: 64 + 12 = 76

Answer: 76

Answer: x = 21

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8x−2=6+10(x−5)

8x+−2=6+(10)(x)+(10)(−5)(Distribute)

8x+−2=6+10x+−50

8x−2=(10x)+(6+−50)(Combine Like Terms)

8x−2=10x+−44

8x−2=10x−44

Step 2: Subtract 10x from both sides.

8x−2−10x=10x−44−10x

−2x−2=−44

Step 3: Add 2 to both sides.

−2x−2+2=−44+2

−2x=−42

Step 4: Divide both sides by -2.

−2x / -2 = -42 / -2

x=21

Answer:

x = 21

Step-by-step explanation:

8x - 2 = 6 + 10(x - 5)

Step 1: Distribute the right side of the equation ("6 + 10(x - 5)") so it'll be easier to find x.

8x - 2 = 6 + 10x - 50

8x - 2 = 10x - 44

Step 2: Subtract 8x from both sides

8x - 2 = 10x - 44

-8x         -8x

-2 = 2x - 44

Step 3: Add 44 to both sides to get 2x alone.

-2 = 2x - 44

+44       +44

42 = 2x

Step 4: Divide both sides by 2 to get x alone

42 = 2x

2      2

x = 21
