Answer:

200 dollars

Step-by-step explanation:

Let's say p equals the cost price of the article. Since the man made 25% profit, that means he got 100% of what he originally paid plus another 25% of what he originally paid. In other words, he sold the article for 125% of the original price. Converting that to a decimal we get:

250=p*1.25

Some simple division gets us a cost price of 200 dollars.

The number of the years to take for the farmland's market value to reach $125,000 will be 19 years.

The missing function will be given below.

[tex]\rm p(t) = 78,125\ e^{0.025t}[/tex]

Let a is the base and x is the power of the exponent function and b is the y-intercept. The exponent is given as

y = aˣ

A patch of farmland is currently worth $78,125. The expected increase in its market value can be modeled by the function below.

[tex]\rm p(t) = 78,125\ e^{0.025t}[/tex]

Then the number of the years to take for the farmland's market value to reach $125,000 will be

[tex]\rm 78,125 \ e^{0.025t} = 125,000\\\\e^{0.025t} = 1.6[/tex]

Then take log on both sides, then we have

0.025t lne = ln 1.6

     0.025t = 0.47

               t = 18.8

               t = 19 years

Answer: the answer to your question is 42.2

Step-by-step explanation:25 x 25 + 34 X 34 = c^2

Answer:

20

Step-by-step explanation:

34 + 90 = 124

180-124 = 56 degrees

c = 56 degrees

to find x we need to use sin

sin = SOH (Sin = opposite/hypotenuse

sin 56 = x/25

sin 56 x 25 = x

x = 20.72593931

x = 20 (rounded to the nearest 10th)

The expression g = 2hm can be written as in terms of g and h when m is the subject is m = g/2h.

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

g  = 2hm

To make m as the subject and solve it:

Divide the above expression by 2h on both sides:

g/2h = m  or

m = g/2h

Thus, the expression g = 2hm can be written as in terms of g and h when m is the subject is m = g/2h.

Answer:

46 degrees

Step-by-step explanation:

The approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.

In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

Here, given equation; (we are using n in place of t)

          -5.e¹⁰ⁿ = -30

      On dividing -5 both sides, we get

           -5.e¹⁰ⁿ/-5 = -30/-5

                e¹⁰ⁿ  = 6

 Taking 'ln' on both side, we get

             10n = ln 6

              n = (ln 6)/10

              n = 1.791759/10

              n = 0.179

Thus, the approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.

If Aleka earns her regular pay or $14 per hour for up to 40 hours of work per week. For each hour over 40 hours of work per week, Aleka earns 14 times her regular pay. Then $728 she earns in a week in which she works 48 hours

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

Given that Aleka earns her regular pay or $14 per hour for up to 40 hours of work per week.

14x40=560

For each hour over 40 hours of work per week, Aleka earns 14 times her regular pay.

Fourteen plus seven equal to twenty one

14+7=21

Twenty one times of eight is equal to one hundred sixty eight

21x8=168

The resultant speed of the plane is 100 mi/hr along the northeast direction.

Speed can be calculated as the ratio of distance traveled to the time taken

First, we need to find our coordinate axis, we will define the x-axis as the east and the y-axis as the north.

We are given that the plane travels at 150 mi/hr at 100° east of north, notice that if we measure from the positive x-axis, this is equivalent to an angle of -10°.

Then the x-component of the velocity ;

150mi/hr x cos(-10°) = 147.7 mi/hr

The y-component of the velocity;

150mi/hr x sin(-10°) = -26 mi/hr.

So, the vector is:

V = 147.7 mi/hr, -26 mi/hr

Now we know that the wind blowing at 50mi/hr at southwest, exactly southwest would be at an angle of 225°,

Thus, the components of the vector are:

x-component: 50mi/hr x cos(225°) = -35.4 mi/hr

y-component: 50mi/hr x sin(225°) = -35.4 mi/hr.

So, the vector is:

W = < -35.4 mi/hr, -35.4 mi/hr>

The sum of the vectors gives the total velocity of the plane in the wind is;

V + W = < 147.7 mi/hr -35.4 mi/hr , -26 mi/hr -35.4 mi/hr >

V + W = <112.3 mi/hr, -61.4 mi/hr>

The direction of a vector is;

θ = Atan(y/x)

Then, in this case the direction of the plane is:

θ = Atan(-61.4 mi/hr/112.3 mi/hr) = -28.7°

An inequality simply refers to a mathematical relation that's used to compare two (2) or more integers (variables) in an equation based on any of the following:

In order to determine the solutions of this system of linear inequalities, we would find the slope of each line.

For line A, we have:

Slope, m = (11 - 3)/(4 - 0) = 8/4

Slope, m = 2.

Mathematically, the standard equation of a line is given by y = mx + b.

y = 2x + 3

y ≤ 2x + 3.

For line B, the slope is equal to 4. Also, the y-intercept from the graph is equal to 5.

The volume of the right squared pyramid with the given base edges and slant height is 32768 cubic centimeters.

The volume of a square pyramid is expressed as;

V = (1/3)a²h

Where a is the base length and h is the height of the pyramid

Given that;

First, we determine the height of the pyramid using Pythagorean theorem.

c² = a² + b²

(40cm) = (32cm)² + h²

1600cm² = 1024cm² + h²

h² = 1600cm² - 1024cm²

h² = 576cm²

h = √576cm²

h = 24cm

Now, we calculate the volume of the right square pyramid;

V = (1/3)a²h

V = (1/3) × (64cm)² × 24cm

V = (1/3) × 409664cm² × 24cm

V = 32768cm³

Therefore, the volume of the right squared pyramid with the given base edges and slant height is 32768 cubic centimeters.
