The measure of the second angle is 15 degrees more then the measure of the 1st angle. The measure of the 3rd angle is 45 degrees more than the measure of the 1st angle. Find the measures of the interior angles in the triangle.

Answers

Let the first angle be x

So, second angle = (x+15)°

and third angle= (x+ 45)°

Now,

x+ (x+15) + (x+45)= 180°. ( Triangle sum property)

x+x+x+15°+45° = 180°

3x+ 60° = 180°

3x= 180°-60°

3x= 120°

x= 120°/3

x= 40°

Now,

first angle=x= 40°

second angle = (x+15)°= 40°+15° = 55°

third angle= (x+45)° = 40°+45° = 85°

Let x and y be independent random variables,suppose the respective expected values are e(x)=8 and e(y)=3 and the respective variances are v(x)=9 and v(y)=6.let z be defined as z =2x-3y+5.based on these data,the value of e(z) is? and the value of v(z) is?

Answers

The expected value of z, e(z), is 12 and the variance of z, v(z), is 90. The expected value of the random variable z, defined as z = 2x - 3y + 5, can be determined using the properties of expected values. The value of e(z) is calculated as 2e(x) - 3e(y) + 5.

Similarly, the variance of the random variable z, denoted as v(z), can be determined using the properties of variances. The value of v(z) is calculated as 2^2v(x) + (-3)^2v(y), since x and y are independent random variables.

Given e(x) = 8, e(y) = 3, v(x) = 9, and v(y) = 6, we can calculate the expected value and variance of z.

e(z) = 2e(x) - 3e(y) + 5

    = 2(8) - 3(3) + 5

    = 16 - 9 + 5

    = 12.

Therefore, the expected value of z, e(z), is 12.

v(z) = 2^2v(x) + (-3)^2v(y)

    = 2^2(9) + (-3)^2(6)

    = 4(9) + 9(6)

    = 36 + 54

    = 90.

Therefore, the variance of z, v(z), is 90.

All measurements of area and weight are rounded up to the next multiples of 50 square
centimetres and 40 grams before calculation.
Jennifer has a letter weighing 125 grams in a 20 cm by 12 cm rectangular envelope that she
wants to send.
What will the postage charge be for Jennifer's letter?
I

Answers

Answer:

$2.12

Step-by-step explanation:

First, let's find the area of Jennifer's envelope: 20 cm x 12 cm = 240 square cm.

Since the area needs to be rounded up to the next multiple of 50 square cm, we will round up 240 square cm to 250 square cm.

Next, let's round up the weight of the letter to the next multiple of 40 grams: 125 grams rounded up to 140 grams.

Now that we have the rounded up values for both weight and area, we can use the formula to find the postage charge:

20 cents per 50 square cm x (250 square cm ÷ 50) = 100 cents

32 cents per 40 grams x (140 grams ÷ 40) = 112 cents

So the total postage charge will be 100 cents + 112 cents = 212 cents = $2.12.

Therefore, the postage charge for Jennifer's letter will be $2.12.

What is the surface area of a closed cylinder with a radius of 4 inches and a height of 6 inches?

Express your answer in terms of pi

48 cm²
40 cm²
32 cm²
80 cm²

Answers

Answer:

The surface area of a closed cylinder is given by the formula 2πr^2 + 2πrh, where r is the radius and h is the height.

Substituting r = 4 and h = 6, we get:

Surface area = 2π(4^2) + 2π(4)(6)

Surface area = 2π(16) + 2π(24)

Surface area = 32π + 48π

Surface area = 80π

So, the surface area of the closed cylinder is 80π square inches.

every three minutes a bus is leaving the airport to drive to the city centre. a car leaves the airport at the same time as a bus und travels the same route as the bus to the city centre. every bus takes 60 minutes for the journey from the airport to the city centre, the car only 35 minutes. how many buses does the car overtake on its way to the city centre? the bus that starts at the same time as the car does not count.

Answers

The car οvertakes twο buses οn its way tο the city center with the given time and distance.

If the autοmοbile and the bus bοth mοved at the same pace, hοw wοuld the answer change?  

On its jοurney tο the city centre, the autοmοbile wοuld never pass any buses if it mοved at the same pace as the bus. This is due tο the fact that if bοth the autοmοbile and the bus are mοving at the same speed, their separatiοn will remain cοnstant. Hence, withοut passing any buses, the autοmοbile wοuld arrive in the city centre at the same time as the bus.

Let us suppοse the distance = p.

The distance travelled by the bus in 60 minutes is d/60.

The distance cοvered by the bus in 35 minutes is:

d/60(35)

Fοr the first bus:

It leaves 60 minutes befοre car, thus the distance travelled is:

(d/60) x 60.

If the car οvertakes thus bus by an additiοnal distance x, then the distance travelled by car is:

d = (d/60) x 35 + (d/60) x 60 + x

d = (5/12)d + x

x = 7/12 d

Fοr the secοnd bus:

The bus wοuld have left the airpοrt 120 minutes befοre the car:

(d/60) x 120

The distance cοvered by car with additiοnal distance y is:

d = (d/60) x 35 + (d/60) x 60 + (7/12)d + y

d = (5/6)d + y

y = 1/6d

The car οvertakes the bus thus,

(7/12)d + (1/6)d = d

d = 12/5

Therefοre, the car οvertakes twο buses οn its way tο the city centre.

The side lengths of the triangle are 17, 144, 145.

What is triangle?

Having three sides, three angles, and three vertices, a triangle is a closed, two-dimensional object. A polygon includes a triangle.

Triangle's characteristics:

A triangle's internal angles are always added together to equal 180 degree.Any two triangle sides added together will always have a length larger than the third side.Half of the product of a triangle's base and height makes up its surface area.

Let x be length of smaller side of triangle

25 + 7x = longer length

26 + 7x = hypotenuse

(26 + 7x)² = (25 + 7x)² + x²

676 + 364x + 49x² = 625 + 350x + 49x² + x²

x² -14x - 51 = 0

(x - 17)(x + 3) = 0

x = {-3, 17}

B


y= 0.4x + 103.4


С


y= -2.5x + 105


D


y= 2.52 + 95


PLEASE HELPP

Answers

The function that models the relationship between the two points is y = 2.5x + 95, which is option D. To determine the function that models the relationship between the two points (2, 100) and (4, 105), we will make use of the slope-intercept form of a linear equation.

The slope-intercept form of the linear equation is given by:y = mx + b

where m is the slope of the line, and b is the y-intercept of the line.

To find the slope, we use the slope formula which is given as:

m = (y₂ - y₁) / (x₂ - x₁)

Where (x₁, y₁) = (2, 100) and (x₂, y₂) = (4, 105).

m = (105 - 100) / (4 - 2)

m = 5/2 = 2.5

So, the slope of the line is 2.5.

Now we substitute the slope and one of the points (2, 100) into the slope-intercept form of the linear equation to find the y-intercept, b.100 = 2.5(2) + b

100 = 5 + b

b = 100 - 5

b = 95

Thus, the function that models the relationship between the two points is y = 2.5x + 95, which is option D.

What is a theorem postulate and theorem?

A mathematical axiom is a statement that, in the absence of evidence, is taken to be true. A theorem in mathematics is a statement that is believed to be true and right and is known as an axiom or postulate. These are general truths that are accepted by all. Axiom and postulate are essentially synonyms in geometry. Propositions that were "clearly true" in antiquity just needed to be stated, not demonstrated and were referred to as such. Axioms are no longer assumed to be "clearly true" in modern mathematics. Simply put, axioms are "background" presumptions we hold.

A mathematical assertion that has been rationally established and proven to be true is called a theorem. A theorem is an axiom's logical conclusion. The "propositions" in geometry are all theorems that are derived from axioms and legitimate rules.

A weight is attached to a spring and reaches its equilibrium position(x=0). It is then set in motion resulting in a displacement of x=8 cos t, where x is measured in centimeters and t is measured inseconds.a) What is the spring

Answers

When the weight moves from x = -8 cm to x = 8 cm, the spring moves from its maximum stretched position to its maximum compressed position.Hence, the spring oscillates between its maximum stretched and compressed positions when the weight is set in motion. Therefore, the spring is a simple harmonic oscillator.

Given: Displacement x

= 8 cos t

= Acos(ωt+ φ) where A

= 8 cm, ω

= 1 and φ

=0. To find: What is the spring?Explanation:We know that displacement is given by x

= 8 cos t

= Acos(ωt+ φ) where A

= 8 cm, ω

= 1 and φ

=0.Comparing this with the standard equation, x

= Acos(ωt+ φ)A

= amplitude

= 8 cmω

= angular frequencyφ

= phase angleWhen the spring is at equilibrium position, the weight attached to the spring does not move. Hence, no force is acting on the weight at the equilibrium position. Therefore, the spring is neither stretched nor compressed at the equilibrium position.Now, the spring is set in motion resulting in a displacement of x

= 8 cos t

= Acos(ωt+ φ) where A

= 8 cm, ω

= 1 and φ

=0. The maximum displacement of the spring is 8 cm in the positive x direction. When the weight is at x

= 8 cm, the restoring force of the spring is maximum in the negative x direction and it pulls the weight towards the equilibrium position. At the equilibrium position, the weight momentarily stops. When the weight moves from x

= 8 cm to x

= -8 cm, the spring moves from its natural length to its maximum stretched position. At x

= -8 cm, the weight momentarily stops. When the weight moves from x

= -8 cm to x

= 8 cm, the spring moves from its maximum stretched position to its maximum compressed position.Hence, the spring oscillates between its maximum stretched and compressed positions when the weight is set in motion. Therefore, the spring is a simple harmonic oscillator.

Final answer:

The displacement of the weight attached to the spring is given by the equation x = 8 cos t. The amplitude of the motion is 8 centimeters and the period is 2π seconds.

Explanation:

The equation x = 8 cos t represents the displacement of a weight attached to a spring in simple harmonic motion. In this equation, x is measured in centimeters and t is measured in seconds.

The amplitude of the motion is 8 centimeters, which means that the weight oscillates between x = 8 and x = -8.

The period of the motion can be determined from the equation T = 2π/ω, where ω is the angular frequency. In this case, ω = 1, so the period T is 2π seconds.

You decide to market your own custom computer software. You must invest $3,255 for computer hardware, and spend $2.90 to buy and package each disk. If each program sells for $13.75, write a system of equations and determine how many disks you must sell to break even.

Answers

Answer:

13.75x = 3,255 + 2.90x

Step-by-step explanation:

Given that,

Amount invested on computer hardware = $3,255

Amount invested to buy and package each disk = $2.90

Selling price for each program = $13.75

We need to find the equation that is used to find how many disks you must sell to break even. Let there are n disks that you must sell.

ATQ,

$3,255 is a fixed amount. $2.90 and $13.75 depends on x.

So,

13.75x = 3,255 + 2.90x

We can solve the above equation to find the no. of disks.

13.75x - 2.90x = 3255

10.85x = 3255

x = 300

Hence, you must sell 300 disks to break even.
