Answer:

When x=−4\5 and y=1\3 we get x+y = -7/15

Step-by-step explanation:

We are given :

x=−4\5 and y=1\3

We need to evaluate : x+y

Solving:

[tex]x+y\\=-\frac{4}{5}+\frac{1}{3}[/tex]

Taking LCM of denominators 5 and 3, we get 15

[tex]=\frac{-4*3+1*5}{15}\\=\frac{-12+5}{15}\\=\frac{-7}{15}[/tex]

So, when x=−4\5 and y=1\3 we get x+y = -7/15

The correct transformation of A (x) will produce the same graph as g(x) is,

⇒ f (x) = f (x + 1)

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

Given that;

The functions are,

⇒ R (x) = 3x

⇒ g (x) = R(x) + 3

Now, We get;

⇒ g (x) = R(x) + 3

⇒ g (x) = 3x + 3

⇒ g (x) = 3 (x + 1)

Thus, The correct transformation of A (x) will produce the same graph as g(x) is,

⇒ f (x) = f (x + 1)

Answer:

His employer contributes with $4712.53 towards his health insurance on an annual basis.

Step-by-step explanation:

With the information provided, you know that Billy's employer pays 65% of his health insurance premium and you can subtract this from 100% to know the percentage that Billy has to pay:

100%-65%=35%

Also, the information states that Billy has $105.73 withheld from his paychecks twice each month and you can multiply this for 24 to find the total amount that he pays per year and that represents 35%:

$105.73*24=$2537.52

Finally, you can use a rule of three to found the amount that represents 65% which would be what his employer pays given that $2537.52 represent 35%:

2537.52 →  35%

     x       ←  65%

x=(2537.52*65)/35

x=$4712.53

According to this, the answer is that his employer contributes with $4712.53 towards his health insurance on an annual basis.

Answer:

4096.50, 4,096.50, $4,096.50, or $4096.5

Step-by-step explanation:

4096.5 percentage is the commission did Mr. Vickers earn last month.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100.Percentage formula = (Value/Total value) × 10

Example: 2/5 × 100 = 0.4 × 100 = 40 per cent

Based on the given conditions, formulate: 7.5% × 54620

Calculate the product or quotient: 4096.5

Answer:

Step-by-step explanation:

Area of a triangle = 1/2bh

b is the base

h is the height

dA/dt = dA/db * db/dt + dA/dh * dh/dt

h = 10cm

b = 6cm

dA/db = h/2 = 10/2

dA/db = 5cm

dA/dh = b/2

dA/dh = 6/2 = 3cm

db/dt = 2.8cm/s

dh/dt = 0.7cm/s

Substitutte into the formula;

dA/dt = 5(2.8) + 3(0.7)

dA/dt = 14 + 2.1

dA/dt = 16.1cm²/s

Hence the rate of change of the area of the triangle is 16.1cm²/s

Answer:

C

Step-by-step explanation:

Please refer to the attachment below.

So, we essentially have a 45-45-90 triangle.

In the 45-45-90 triangle, the two legs are equivalent.

Therefore, since one of the legs is 10ft, the other leg, the height of the tree, must also be 10ft.

Hence, our answer is C.  

Answer:

a) $21

b) $133.75

c) $233.75

Step-by-step explanation:

Edan buys 3 tickets to a concert. When the delivery charge of $7.75 per order is added to the cost of the tickets, the total cost is $70.75.

A) Create an algebraic equation for this problem. Use the equation to determine the cost of each ticket. Verify your solution.

Let the number of tickets be represented by x

The equation is:

3x + 7.75 = 70.75

3x = 70.75 - 7.75

3x = 63

x = 63/3

x = $21

Each ticket cost $21

B) Olivia is Edan's cousin. Olivia has asked Edan to purchase tickets for her friends as well. Edan has now purchased 6 tickets in total. Use an algebraic equation to determine the total cost to Edan?

1 ticket cost = $21

Let the number of tickets be represented by x

Hence, the equation is

21x + $7.75

21 × 6 + $7.75

= 126 + $7.75

= $133.75

C) Olivia has come down with the flu, and her friends no longer want to attend the concert. Edan is thinking of selling the 6 tickets she bought. Her goal is to earn $100 after selling the tickets. Using the equations from part a) and b), how much should Edan sell each ticket for, if she

Profit = Selling price - Cost Price

Cost price = $133.75

Profit = $100

Selling price = Cost price + Profit

Selling price = $133.75 + $100

= $233.75

15 long-sleeved shirts can be ordered.

Step-by-step explanation:

x = amount of short-sleeved.

y = amount of long-sleeved.

10x + 12y = 300

10(12) + 12y = 300

120 + 12y = 300

12y = 300 - 120

12y = 180

y = 180 / 12
