Bryan is paid $32 per hour and works 8 hours per day. He receives one paid day off for each 16 days that he works. What is his true hourly wage?

A. $40 per hour
B. $34 per hour
C. $32 per hour
D. $48 per hour

Answers

I am taking the test the answer is B $34 hope this helps

$40 per hour is his true hourly wage, option A is correct.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Bryan works 8 hours per day, so he works 16 x 8 = 128 hours during the 16-day period.

His pay for the 16-day period is 16 x 8 x $32 = $5,120.

He receives one paid day off for each 16 days that he works, so he gets 16/1 = 16 paid days off for every 16 days worked.

Therefore, he actually works for 16 - 16/1 = 0 days during those 16 days.

His true hourly wage is his total pay divided by the actual number of hours he works:

True hourly wage = $5,120 / 128 hours = $40 per hour

Hence, $40 per hour is his true hourly wage, option A is correct.

Mandana is ordering new tile for her kitchen floor. The area of the floor is 116.9 square feet, and she wants to order between 15% and 20% extra of the materials. Which of the following is a reasonable amount of tile for Mandana to order?

A. 131 square feet B. 138 square feet C. 133 square feet D. 141 square feet

Answers

In order to know what is the reasonable amount of tile for Mandana to order, you have to divide the choices with the area of the floor and deduct with 1 and multiply by 100. You have to assess if the answer you will get will fall between 15% and 20% which is the goal of Mandana.

a. 131/116.9 = (1.1206 – 1) x 100 = 12.06%, this does not fall between 15% and 20%

b. 138/116.9 = (1.1805 – 1) x 100 = 18.05%, this fall between 15% and 20%

c. 133/116.9 = (1.1377 – 1) x 100 = 13.77%, this does not fall between 15% and 20%

d. 141/116.9 = (1.2062 – 1) x 100 = 20.62%, this does not fall between 15% and 20%

Therefore, the reasonable amount of tile for Madana to order that is between 15% and 20% extra of the materials is 138 square feet.

Answer:

Option: C is the correct answer.

C. The interval on the x-axis of the histogram is inconsistent

Step-by-step explanation:

Clearly after looking at the histogram we see that the interval on the x-axis are inconsistent.

Since, the intervals given are:

0-4 ( length of interval is 4)

5-9 ( length of interval is 4)

10-14 ( length of interval is 4)

But the intervals:

(15-19) is missing in the given histogram.

And then a interval of length 4 is given i.e. (20-24)

Hence, option: C is the correct answer.

Joe borrowed $900 from Sam for six months. How much will Sam earn if he charges Joe a simple interest rate of 4 percent?

Answers

700 times 2 is right nothing besides that makes sense

Answer:

$18.

Step-by-step explanation:

We have been given that Joe borrowed $900 from Sam for six months. The interest rate charged by Sam is 4%.

We will use Simple interest formula to solve our given problem.

[tex]I=PrT[/tex], where,

[tex]I=\text{Simple interest}[/tex],

[tex]P=\text{Principal amount}[/tex],

[tex]r=\text{Interest rate in decimal form}[/tex],

[tex]T=\text{Time in years}[/tex].

Let us convert our given rate in decimal form.

[tex]4\%=\frac{4}{100}=0.04[/tex]

12 months = 1 year.

1 month = 1/12 year.

6 months = 6/12 year = 1/2 year = 0.5 year.

Upon substituting our given values in simple interest formula we will get,

[tex]I=900*0.04*0.5[/tex]

[tex]I=900*0.02[/tex]

[tex]I=18[/tex]

Therefore, Sam will earn $18 if he charge Joe a simple interest rate of 4 percent.

after a translation the size nor shape of the triangle changes, every point of the triangle moves the same distance in the same direction.
if we take point A and F
x coordinates of A = 3 and F = 8
the change that has happened can be noted as 'm'
3 + m = 8
m = 5
this means that the point has moved 5 units to the right
y coordinates of A = 8 and F = 4
change that happened is 'n'
8 + n = 4
n = -4
this means that point has moved 4 units downwards

Therefore the correct answer is Translate triangle ABC down 4 units, and then translate triangle ABC right 5 units

Explain how to find the degree of a polynomial.

Answers

The degree of a polynomial is the highest number as an exponent in a term, for example, 5x^3+5x^2, 3 is the degree. To find it, you need to either just find the highest number or add up multiple degrees in one term. An example of this is 5x^3y^3+4x^3y^2. Since 3+3=6 and 3+2=5, the first term has the highest degree.

Answer:

The Degree of a Polynomial is the largest of the degrees of the individual terms. Add the degrees of the variables of each term to decide what is the Degree of the Polynomial. Degree of term 1 is 2 (1+1= 2), Degree of term 2 is 6 (2+4 = 6), Degree of term 3 is 7 (5+2 = 7) 7 is the Degree of the Polynomial.

John wants to build a corral next to his barn. He has 300 feet of fencing to enclose three sides of his rectangular yard.
a. What is the largest area that can be enclosed?
b. What dimensions will result in the largest yard?

Answers

Let's first define the variables:
x = width
300 - 2x = long
The area will be:
A = (x) * (300 - 2x)
A = 300x - 2x²
We look for the maximum area, for this, we derive:
A '= 300 - 4x
We match zero:
0 = 300 - 4x
x = 300/4 = 75
Therefore, the width is:
x = 75 feet
The length is:
300 - 2x = 300 - 2 (75) = 300-150
150 feet
Answer:
Part A:
The maximum area will be:
A = (150) * (75) = 11250 square feet
Part B:
The dimensions are:
Length = 150 feet
width = 75 feet

A cell phone plan charges $15$15 per month for 300300 text messages. The plan charges $0.08$0.08 for each additional text message. You use 6060 additional texts this month. What is your bill for the month?

Answers

The company charges 15 dollars per month for first 300 text messages and thereafter 0.08 dollars for any additional text message.

It says that we used additional 60 text messages (after fair usage of first 300 messages in the plan).

Our bill for this month would be sum of charges for 300 messages and charges for additional 60 messages.

Total bill = 15 dollars + 60x0.08 dollars = (15 + 4.80) dollars.

Total bill = 19.80 dollars.

Hence, our bill this month would be 19.80 dollars.

Answers

36 because x^2 + 12x + 36 = ( x + 6 )^2 is a perfect square trinomial;

Given is the expression, x² + 12x + n

It says to find value of 'n' that converts it into a Perfect Square Trinomial.

A perfect square trinomial is a quadratic expression which has a single root with multiplicity 2. i.e. it is of the form :- x² + 2bx + b² = (x + b)²

On comparing it with the given expression, we get :-

So 2b = 12 and n = b²

b = 6

and so b² = 6² = 36.

⇒ n = 36

Hence, x² + 12x + 36 = (x + 6)² i.e. n = 36 is the final answer.

The length of a rectangle is 2 ft longer than its width. if the perimeter of the rectangle is 32 ft , find its area.

Answers

The length of would be 9 and the width 7, resulting in an area of 63

Final answer:

To find the area of the rectangle, first solve for the width using the perimeter formula. The width is found to be 7 ft. Then calculate the length as w + 2, which is 9 ft. The area is the product of length and width, resulting in 63 square feet.

Explanation:

To solve this problem, we need to set up equations based on the information given about the rectangle's dimensions and the perimeter.

Step 1: Define Variables

Let w be the width of the rectangle in feet. Consequently, the length l will be w + 2 feet, since the length is 2 feet longer than the width.

Step 2: Perimeter Equation

The perimeter (P) of a rectangle is given by 2(l + w). We can use the perimeter given (32 ft) to create an equation: 2(w + w + 2) = 32.

Step 3: Solve for w

Combine like terms and divide both sides by 2 to find w:
4w + 4 = 32
w = 7 ft.

Step 4: Find l

The length is w + 2, which is 7 ft + 2 ft = 9 ft.

Step 5: Calculate Area

The area of a rectangle is l × w. Therefore, the area is 9 ft × 7 ft = 63 square feet.

Arnold's company reimburses his expenses on food, lodging, and conveyance during business trips. The company pays $40 a day for food and lodging and $0.50 for each mile traveled. Arnold drove 400 miles and was reimbursed $2600. Part A: Create an equation that will determine the number of days x on the trip (3 points) Part B: Solve this equation justifying each step with an algebraic property of equality. (6 points) Part C: How many days did Arnold spend on this trip? (1 points)

Answers

We know for the problem that Arnold drove 400 miles during his business trip, and the cost of each mile is $0.50, so the total cost of the miles the company will reimburse is: [tex](400)(0.5)=200[/tex]$.

Part A. We now know that the total cost of the miles the company have to pay to Arnold is $200. We also know the company pays him $40 a day for food and lodging. So let [tex]x[/tex] represent the number of days of Arnold's business trip:
[tex]y=40x+200[/tex]
where
[tex]y[/tex] is the amount the company will reimburse Arnold after [tex]x[/tex] days.
[tex]x[/tex] is the number of days.

Part B. We know that the amount the company will reimburse Arnold is $2600, so [tex]y=2600[/tex]. Lets replace that value in our equation and solve for [tex]x[/tex] to find the number of days:
[tex]y=40x+200[/tex]
[tex]2600=40x+200[/tex]
The first thing we are going to do to solve our equation is subtract 200 to both sides using the subtraction property of equality:
[tex]2600-200=40x+200-200[/tex]
[tex]2400=40x[/tex]
Next, we are going to divide both sides of the equation by 40, using the division property of equality, to find the value of [tex]x[/tex]:
[tex] \frac{2400}{40} = \frac{40x}{40} [/tex]
[tex]60=x[/tex]
Finally, we can use the reflexive property of equality to get:
[tex]x=60[/tex]

Part C. We can conclude that Arnold spend 60 days in his business trip.

6 hours later = 3(3(3(80)))
8 hours later = 3(3(3(3(3(80)))))
8 hours later = [tex] 3^{4} [/tex] x 80
8 hours later = 6480 (Answer C)

We find the number of 2 hours period in that 8 hours
8 ÷ 2 = 4
It starts at 80 pounds
It tripes every 2 hours

If it triples every 2 hours, it will triple 4 times. 80x3x3x3x4=6480

A bowl of fruit contains 3 apples, 4 bananas, 2 pears and 1 orange.Aminata chooses one piece of fruit at random.What is the probability that she chooses.

Answers

Final answer:

The probability of Aminata choosing a specific type of fruit is calculated by dividing the number of that fruit by the total number of fruits in the bowl. Different fruit types have different probabilities due to their varying quantities.

Explanation:

The question asks about the probability of Aminata choosing a specific type of fruit from a bowl containing 3 apples, 4 bananas, 2 pears, and 1 orange. To find the probability of Aminata choosing any one type of fruit, we first need to determine the total number of fruit pieces in the bowl, which is 3 apples + 4 bananas + 2 pears + 1 orange = 10 pieces of fruit.

The probability of selecting any specific type of fruit is then calculated by dividing the number of that fruit type by the total number of pieces.

The probability of choosing an apple is 3/10.The probability of choosing a banana is 4/10 or simplified to 2/5.The probability of choosing a pear is 2/10 or simplified to 1/5.The probability of choosing an orange is 1/10.

Each fruit type has a different probability of being chosen based on its quantity in the total mix of fruits.

[tex]y = \frac12(5)^{x[/tex]

Rewrite them as

[tex]f(x) = -\frac12(5)^{x-3[/tex]

From the above, we have that

f(x) is first reflected across the x-axis

This is represented by the loss of negative factor in g(x)

Then f(x) is shifted left by 3 units

This is represented by the loss of -3 in g(x)

Hence, the transformation of f(x) to g(x) is reflection across the x-axis followed by a shift to the left by 3 units
