Answer: 13 markers and one pen

Step-by-step explanation:

14/2 = 7

7+6=13 markers

Which means there is only one pen left

From the obtained equation, there are 4 pens and 10 markers.

Given that, there are 14 pens and markers.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of pens be p.

Then, the number of markers will be p+6

Now, the equation is p+p+6=14

⇒ 2p+6=14

⇒ 2p=8

⇒ p=4

Thus, p+6=10

Therefore, from the obtained equation, there are 4 pens and 10 markers.

The unit rate is 32.6 ft/s and approximately 0.03 s/ft.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

An object traveled 691.12 feet in 21.2 seconds.

So, the unit rate as feet per second.

= 691.12/ 21.2

= 32.6 ft/s

and, the unit rate as second per feet

= 21.2/ 691.12

= 0.03 s/ ft

Hence, the unit rate is 32.6 ft/s and approximately 0.03 s/ft

As per the angle sum property of quadrilateral, then values of x is 245 and the value of y is 341

Angle sum property of quadrilateral:

The angle sum property states that the sum of all the angles of the quadrilateral is 360 degree.

Given,

The angles of the quadrilateral are 5x degrees, (4y minus 2 )degrees, (13x plus 10 )degrees, and 10y degrees.

Now we have to write and solve a system of linear equations to find the values of x and y.

While we looking into the given angles, then we get the values

=> 5x°

=> (4y - 2)°

=> (13x + 10)°

=> 10y°

We know that, the sum of all the angles of the quadrilateral is 360°.

So, it ca be written as,

=> 5x° + (4y - 2)° + (13x+ 10)° + 10y° = 360°

=> 18x° + 14y° - 8° = 360°

=> 18x° + 14y° = 354°

When we divide all of them by 2, then we get the equation as,

=> 9x° + 7y° = 177°

Now we have to rewrite the given equation as,

=> 9x° = 177° - 7y°

=> x° = (177° - 7y°)/9

Apply these value on the angles, then we get,

=> 13(177 - 7y)/9 = -10

=> 13(177 - 7y) = 90

=> -7y = -90 - 2301

=> 7y = 2391

=> 341

Then the value of x is

=> 245

Answer:

m∠T = 60°

m∠U = 60°

TS = 13 cm

SU = 13 cm

Step-by-step explanation:

The diagram shows that 2 sides, UT and TS, are equal, so it is an isosceles triangle. Since it is an isosceles triangle, the two angles opposite the equal sides are also congruent to each other, so m∠S = m∠U = 60°.

Now we know the measure of 2 angles, we can find the measure of the third angle, by subtracting the 2 known angles from 180°.

m∠T = 180° - m∠S - m∠U

m∠T = 180° - 60° - 60°

m∠T = 60°

Since all 3 angles are congruent, it is an equilateral triangle, therefore all the sides must be congruent too. So UT = TS = SU = 13 cm.

The function of Car A is an exponential function.

The function that describes the value is g(x) = [tex]18,000(0.94^{x})[/tex].

The value of f(x) in 9 years is $10,313.91.

The function of Car B is a linear function.

The function that describes the value is  g(x) = 18,500 -750x.

The value of f(x) in 9 years is $11,750.

The value of the car declines with the passage of time. Thus, the value of the car depreciates with the passage of time.

A linear function is a function that has a single variable raised to the power of 1. A linear function increases or decreases by a constant value.  

The general form of a linear function is f(x) = a + bx

Where:

Rate of change = value of the car B in year 2 - value of the car B in year 1

17,000 - 17,750 = - 750

g(x) = 18,500 -750x

Value of g(x) when x is 9:

g(x) = 18,500 -750(9)

g(x) = 18,500 - 6,750

g(x) = $11,750

An exponential function can be described as an equation with exponents. The exponent is usually a variable.

The general form of exponential function is f(x) = [tex]e^{x}[/tex]

Where:

• x = the variable

• e = constant

Constant = (Value of the car in year 2 / value of the car in year 1) - 1

Constant = (16,346.60 / 17,390) - 1 = -0.06 = -6%

g(x) = [tex]18,000(0.94^{x})[/tex]

Value of the car in 9 years =  [tex]18,000(0.94^{9})[/tex] = $10,313.91

The height of the model of the lighthouse in inches is 20 inches

The real height of the lighthouse = 160 feet

The scale model of the light house has scale of

1 inch : 8 feet

Consider the height of the model of the lighthouse is x

Then the proportion of the scale model of the lighthouse and the actual height will be

1 inch / 8 feet = x inches / 160 feet

Cross multiply the terms

1 × 160 = 8x

Multiply the terms

8x = 160

Divide both side of the equation by 8

8x / 8 = 160 / 8

x = 20 inches

Answer:

  (b) 150 feet

Step-by-step explanation:

You want to know the height of a kite at the end of 225 feet of string, flying at an angle of elevation of 45°.

The 45° angle in the given right triangle tells you this is one of the "special" right triangles. Its side lengths have the ratios ...

  1 : 1 : √2

where √2 is the hypotenuse.

That means the other two legs of this right triangle are ...

  (225 ft)/√2 ≈ 159.099 ft

Rounded to the nearest 50 feet, this is about 150 feet.

Additional comment

The sine function relates the angle value to the opposite side:

  Sin = Opposite/Hypotenuse

  Opposite = Hypotenuse · Sin

  height = (225 ft)·sin(45°) = 225 ft/√2 ≈ 159.099 ft

12 is the marginal cost at the production level of 1000 units.

A differential equation is an equation that contains one or more functions with its derivatives.

The marginal cost represents the additional cost if 1 more unit is produced. So, we can find the marginal cost by computing C(1,001) and subtracting (1,000)

First, let's evaluate the cost at both x= 1,001 and x=1,000

C(1000)=0.002(1000)^2+8(1000)+6000

=0.002(1000000)+8000+6000

=2000+8000+6000

=16000

C(1001)=0.002(1001)^2+8(1001)+6000

=2004.002+8008+6000

=16012

The difference between these costs is $12.002. Rounding to the nearest cent, we find a marginal cost of $12 per unit. Let's see if we get a similar result from the derivative.

Hence 12 is the marginal cost at the production level of 1000 units.

The needed Sample size is 32.2 so that the confidence interval will have a margin of error of 0.06.

We have provided that , An article in a medical journal approx. 18% of operation results complications.

Using the estimate formula, for standard margin of error

Margin of error (E) = Z x √p(1-p)/n

where , E---> margin of error

Z---> estimate value

p----> sample proportion

n -----> Sample size

we have the value of E = 0.06 , p = 18% = 0.18

put all the values in above formula we get,

0.06 = Z × √0.18× 0.82/n

critical value or Z-value for sample proportion 0.18 is 0.91

Now, 0.06 = 0.91 × √0.18×0.82/n

The pair of angles that gives 180° on adding is known as Supplementary angles. In other words, the sum of two supplementary angles is 180°. Two pairs of Supplementary angles will always form a linear pair.

Here we have

∠1,  ∠2,  ∠3, and ∠4 are formed by 2 intersecting lines

As we know      

∠1,  ∠2 is a linear pair and form supplementary angles

=> Sum of the ∠1,  ∠2 will equal 180°  

∠2,  ∠3 is a linear pair and form supplementary angles

=> Sum of the ∠2,  ∠3 will equal 180°  

Therefore,

By the Definition of supplementary angles ∠1+∠2= 180° and ∠2+∠3= 180°

From the above observations,

=> ∠1+∠2= 180° and ∠2+∠3= 180°

=> ∠1 + ∠2 = ∠2 + ∠3  

Therefore,
