Answer:

w = 7

Step-by-step explanation:

12.75w + 25 = 114.25

12.75w + 25 - 25 = 114.25 - 25

12.75w = 89.25

12.75w/12.75 = 89.25/12.75

w = 7

The average yearly salary of the final year is 67000 in dollars.

An average is a single number selected to stand in for a collection of numbers; it is frequently the product of the sum of the numbers divided by the total number of the collection. For example, the average of the integers 2, 3, 4, 7, and 9 is 5.

Let x = the average salary of an individual with the bachelor's degree, in dollars.

Then the average salary of an individual with master's degree is (2x - 35000)in dollars.

According to the sum of these salaries is 118000 dollars:

x + (2x-35000) = 118000

by solving we get

x = 153000/3

x = 51000

Hence, The average salary of an individual with the bachelor's degree is 51000 in dollars.  

the average salary of an individual with the master's degree (2*51000 - 35000) = 67000 in dollars.

Putting SIN² A in evidence

SIN² A(1 + TG² A) = TG² A

SIN² A(SEC² A) = TG² A

SIN² A/COS² A = TG² A

TG² A = TG² A

Answer:

0%

Step-by-step explanation:

The gain on the first oven = 18000 x 20% = 18000 x 20/100
= 18000 x 0.2 = 3600. Since it is a gain, we have to add this number

So selling price = 18000 + 3600 = 21600

The loss on the second oven is also the same 18000 x 0.2 = 3600. This time, it being a loss, selling price = 18000-3600 Total= 14400

The total before sales price of both ovens C  = 18000 + 18000 = 36,000

Total sold price S = 14, 400 + 21,600 = 36000

So net gain/loss = S - C = 36000 - 36000 = 0

So net gain/loss as percent = 0%

Answer: a

Step-by-step explanation:

First term

[tex]\int \sqrt{10x-15} \mathrm{dx}[/tex]

We can use the substitution u=10x-15, meaning dx = 1/10 du.

[tex]=\frac{1}{10} \int \sqrt{u} \mathrm{du}\\\\=\frac{1}{15}u^{3/2}+C\\\\=\frac{1}{15}(10x-15)^{3/2}+C[/tex]

A binary connection in mathematics links elements of one set, referred to as the domain, with elements of another set, referred to as the codomain. A new set of ordered pairs made up of elements from sets X and Y and x in X is known as a binary relation across these sets.

The variable Y as a function of X is represented by table number 4. Because for every value of X there is a different value of Y.

Answer:

D

Step-by-step explanation:

an = 3/4 × an-1

let's see for n = 2

a2 = 3/4 × a1 = 3/4 × 4

n = 3

a3 = 3/4 × a2 = 3/4 × 3/4 × a1 = 3/4 × 3/4 × 4 = 9/16 × 4

so, we see, we multiply 3/4 one time less than n by itself and then by 4.

that makes D the correct answer.

the multiplication by (n - 1) in answer C would add 3/4 n-1 times instead of multiplying it n-1 times.

to apply n-1 multiplications we need to use n-1 as exponent.

The combined estimated weight of the two whales is 945.7 Pounds.

The estimated weight of a blue whale = 3.46 × 105

Total estimated weight of a blue whale = 363.3 Pounds

Now, the estimated weight of a sea whale = 5.6 × 104

Total estimated weight of a sea whale = 582.4 Pounds

For finding the combined estimated weight of the two whales,

we will add the total estimated weight of both whales.

Here is how we will do it:

Total estimated weight of a blue whale + Total estimated weight of a sea whale

= 363.3 Pounds + 582.4 Pounds

Step-by-step explanation:

Whenever you have a subtraction symbol next to a negative it automatically becomes positive.

Step-by-step explanation:

the slope is a line is always the factor of x.

and it is the ratio (y coordinate difference / x coordinate difference) when going from one point to another.

y = 2x + 4

has the slope 2. which is 2/1. so, for every increase of x by 1 unit, y increases by 2 units.

and this line has a y-intercept of 4 (the y-value when x = 0).

remember, the slope-intercept form of a line is

y = ax + b

a is the slope, b is the y-intercept.

a perpendicular slope (90°) turns that ratio upside down and flips the sign (because if the original line was going up, the perpendicular line is going down and vice versa).

so, the slope of the perpendicular line is -1/2.

the y-intercept was already given to us, so the desired line equation is

y = -1/2 x + 3

or

y = -x/2 + 3

The rate of change of the cost in dollars with respect to the number of t-shirts printed is $0.75 per shirt.

An equation is an expression that shows the relationship between two or more numbers and variables.

A linear function is in the form:

y = mx + b

Where m is the rate of  change and b is the initial value of y.

Given that the cost f(x) in dollars for printing x, t-shirts is given by:

f(x) = 100 + 0.75(x - 50)

f(x) = 0.75x + 62.5

Comparing with linear function, the rate of change is 0.75

The rate of change of the cost in dollars with respect to the number of t-shirts printed is $0.75 per shirt.
