The value of x is equal to 35° and the measure of the angle between points AY, m∠AND is equal to 80°.

From the question, we observe that the larger angle between m∠ANY consists of the two angles between m∠AND and m∠YND, so we shall sum the two small angles and equate the result to the larger angle to solve for the value of x as follows:

2x + 10 + 30 = 110°

2x + 40 = 110

2x = 110 - 40 {subtract 40 from both sides}

2x = 70

x = 70/2 {divide through by 2}

x = 35°

so we can evaluate for the angle between m∠AND as follows:

m∠AND = 2(35) + 10

m∠AND = 70 + 10

m∠AND = 80°

In conclusion, the value of x is equal to 35° and the measure of the angle between points AY, m∠AND is equal to 80°.

The GCF (Greatest Common Factor) of 2.4x and 12 is 2.4. Therefore, we can write: 2.4x - 12 = 2.4(x - 5)

What is expression ?

In mathematics, an expression is a combination of symbols and/or numbers that represents a mathematical quantity or relationship. It can be a simple numerical value or a more complex arrangement of terms and operations.

To generate an expression equivalent to 2.4x - 12 using the GCF, we need to find the largest common factor between the terms 2.4x and 12.

First, we can simplify 2.4x by dividing both the numerator and denominator by 0.4, which gives us:

2.4x = 6x

Now, we can find the GCF between 6x and 12, which is 6. We can factor out this GCF from both terms to get:

2.4x - 12 = 6(x - 2)

So, the expression equivalent to 2.4x - 12 using the GCF is 6(x - 2). This expression represents the same quantity as 2.4x - 12, but is simplified and factored.

The correct answer is Option B, The amount Jonathan is paid for each hour over 10.

The expression { 7 . 5 x ; 0 ≤ x ≤ 10 75 + 9 ( x − 10 ); x > 10 } gives the amount of money Jonathan is paid each week based on the number of hours he works, x. The first part of the expression, 7.5x, applies when x is between 0 and 10, inclusive. The second part of the expression, 75 + 9(x - 10), applies when x is greater than 10.

So, the term 9(x - 10) represents the amount he is paid for each hour over 10. When Jonathan works more than 10 hours, he is paid a flat rate of $75 for the first 10 hours, and then an additional $9 for each hour over 10. Therefore, if Jonathan works x hours and x is greater than 10, then he is paid 9(x - 10) dollars for each hour over 10.

The value of 2(s + t)^{3} - 6 is 244.

What is an equation?

In mathematics, an equation is a statement that asserts the equality of two expressions, usually separated by an equals sign (=).

For example, the equation 3x + 5 = 11 asserts that the expression 3x + 5 is equal to the expression 11. An equation can have one or more variables, which are typically represented by letters. In the example above, x is the variable.

To evaluate 2(s + t)^{3} - 6 when s = 3 and t = 2, we can substitute 3 for s and 2 for t in the expression and simplify.

So we have:

2(s + t)^{3} - 6 = 2(3 + 2)^{3} - 6 (substituting s = 3 and t = 2)

= 2(5)^{3} - 6 (evaluating the expression inside the parentheses)

= 250 - 6 (cubing 5 and multiplying by 2, and then subtracting 6)

The factored representation of the quadratic function 2x² - 10x - 48 is given as follows:

2(x - 8)(x + 3).

The quadratic function for this problem is defined as follows:

2x² - 10x - 48

The leading coefficient of 2 is common to all the terms of the expression, hence the expression can be simplified as follows:

2x² - 10x - 48 = 2(x² - 5x - 24).

The term with the square of x can be simplified as follows:

x² - 5x - 24 = (x - 8)(x + 3).

Meaning that x = 8 and x = -3 are the roots of the quadratic function, hence, considering the leading coefficients and the linear factors, the simplified expression is given as follows:

2x² - 10x - 48 = 2(x - 8)(x + 3).

The factorization of the quadratic equation is:

y = 2*(x + 3)*(x - 8)

Here we have the quadratic equation:

2x^2 - 10x - 48

To factorize it, we need to find the roots of the quadratic, to do so we need to solve the equation:

y = 2*x^2 - 10*x - 48 = 0

2x^2 -10x - 48 = 0

Dividing by 2 in both sides we will get:

(2x^2 - 10x - 48)/2 = 0/2

x^2 - 5x - 24 = 0

Now we can use the quadratic formula to get the roots:

[tex]x = \frac{5 \pm \sqrt{(-5)^2 - 4*1*-24} }{2} \\\\x = \frac{5 \pm 11}{2}[/tex]

The roots are:

x = (5 + 11)/2 =8

The probability that O and E are together in a randomly arranged word "COMPUTER" is 0.25, or 25%.

Statistics and probability theory both make substantial use of probability, which is a measure of the possibility or chance of an event occurring. A number between 0 and 1, where 0 denotes an event that is impossible and 1 denotes an event that is certain, is used to indicate the likelihood of an occurrence.

We must count the number of favourable possibilities—those that match the event of interest—and divide that number by the total number of potential outcomes in order to calculate the probability of an occurrence.

There are 8 letters in the word, so the total number of arrangements is 8! = 40,320.

For O and E to be together we consider it as a sing letter, thus:

There are 7! ways to arrange the letters of new word.

Now, OE can be written as OE or EO thus:

2 x 7! = 10,080

Now, the probability of O and E together is:

Probability = 10,080 / 40,320

Probability = 0.25

Hence, the probability that O and E are together in a randomly arranged word "COMPUTER" is 0.25, or 25%.

the answer is "EF = 3.16". According to condition of Similar triangles.

How to solve these problem?

To solve this problem, we will use the property of similar triangles, which states that corresponding angles of similar triangles are equal, and their corresponding sides are proportional.

First, we need to find the ratio of the sides of the two triangles. We can do this by dividing the length of one side of triangle ABC by the corresponding side of triangle DEF. Let x be the length of EF, then:

AB/DE = BC/EF = CA/DF

Substituting the given values, we get:

11/4.4 = 7.9/x = 7.6/(DE + x)

Solving for x, we get:

x = 3.16

Therefore, EF = 3.16.

Hence, the answer is "EF = 3.16".

Note that we can also check our answer by verifying that the corresponding sides of the two triangles are proportional using the ratios we found:

AB/DE = 11/4.4 = 2.5

BC/EF = 7.9/3.16 = 2.5

CA/DF = 7.6/(4.4+3.16) = 2.5

Since the ratios are all equal, we can conclude that the triangles are similar.

Step-by-step explanation:

To solve this problem, we can use the concept of present value of money. We want to find the equal payments that will settle the obligations in 5 and 11 months, respectively, and we know the amounts and due dates of the obligations.

Using a 6% interest rate, we can find the present value of each obligation on each comparison date, and then solve for the unknown equal payments.

Comparison date is 11 months hence:

The present value of $10,000 due in 3 months at a 6% interest rate is:

PV1 = $10,000/(1 + 0.06 * 3/12) = $9,703.70

The present value of $20,000 due in 7 months at a 6% interest rate is:

PV2 = $20,000/(1 + 0.06 * 7/12) = $19,003.22

To settle these obligations with two equal payments, we can set up the equation:

PV1/(1 + 0.06 * 8/12) + PV2/(1 + 0.06 * 4/12) = x + x/(1 + 0.06 * 6/12)

where x is the size of each payment.

Simplifying the equation, we get:

9703.70/1.04 + 19003.22/1.02 = 2.5x

Solving for x, we get:

x = $8,102.67

Therefore, each payment should be $8,102.67.

Comparison date is now:

The present value of $10,000 due in 3 months at a 6% interest rate is:

PV1 = $10,000/(1 + 0.06 * 3/12) = $9,703.70

The present value of $20,000 due in 7 months at a 6% interest rate is:

PV2 = $20,000/(1 + 0.06 * 7/12) = $19,003.22

To settle these obligations with two equal payments, we can set up the equation:

PV1 + PV2/(1 + 0.06 * 4/12) = x + x/(1 + 0.06 * 6/12)

where x is the size of each payment.

Simplifying the equation, we get:

9703.70 + 19003.22/1.02 = 2.5x

Solving for x, we get:

x = $8,556.54

Therefore, each payment should be $8,556.54.

Comparison date is 3 months:

The present value of $10,000 due in 3 months at a 6% interest rate is:

PV1 = $10,000

The present value of $20,000 due in 7 months at a 6% interest rate is:

PV2 = $20,000/(1 + 0.06 * 4/12) = $19,508.67

To settle these obligations with two equal payments, we can set up the equation:

PV1/(1 + 0.06 * 8/12) + PV2 = x + x/(1 + 0.06 * 6/12)

where x is the size of each payment.

Simplifying the equation, we get:

10000/1.04 + 19508.67 = 2.5x

Solving for x, we get:

x = $8,433.13

Therefore, each payment should be $8,433.13.

Dividing this by the correct value ($38.07) gives:

$0.01 / $38.07 ≈ 0.0002626

Multiplying by 100 gives the percent error:

0.0002626 x 100% ≈ 0.02626%

Answer: We can use the formula for the future value of an annuity with monthly compounding to determine how much money should be deposited:

FV = P * ((1 + r/n)^(n*t) - 1) / (r/n)

where:

FV = future value (the amount we want to accumulate, which is $13,000 in this case)

P = periodic payment (the amount we need to deposit each month)

r = annual interest rate (2.5% in this case)

n = number of compounding periods per year (12 for monthly compounding)

t = number of years (4 in this case)

We want to solve for P, so we can rearrange the formula as follows:

P = FV * (r/n) / ((1 + r/n)^(n*t) - 1)

Substituting the given values, we get:

P = 13000 * (0.025/12) / ((1 + 0.025/12)^(12*4) - 1)

Calculating this expression gives us:

P = $279.27 (rounded to the nearest cent)

Therefore, we need to deposit $279.27 each month for 4 years in an account that earns 2.5% compounded monthly in order to accumulate $13,000. Alternatively, if we want to make a single deposit today, we can multiply this monthly amount by 12 and then by 4, which gives us:

P = $13,414.08 (rounded to the nearest cent)

Therefore, we need to deposit $13,414.08 today in an account that earns 2.5% compounded monthly in order to accumulate $13,000 after 4 years.

The length of the AG in the cuboid is 7.56 cm.

To find the Length of the diagonal AG, we need to find the length of AC. Use the Pythagorean formula to find the length of AC. Now use the trigonometric ratios formulas to find the length of AG.  

Here we have a cuboid

Where AD = 23 cm, DC = 18 cm and ∠GAC = 75°  

From the right angle triangle, ADC

=> AC² = AD² + DC²    [ Using the Pythagorean formula ]

=> AC² = (23)² + (18)²

=> AC² = 529 + 324

=> AC = √853 = 29.20    

Hence, the length of AC = 29.20

From the right angle triangle, AGC

=> Cos B = AC/AG

=> Cos 75° = 29.20/AG

=> AG = Cos 75° (29.20)

=> AG = (0.26)(29.20)

=> AG = 7.56

Therefore

The length of the AG in the cuboid is 7.56 cm.

As a result, y = 200 + 160[tex]e^{(0.4t)}[/tex] is the answer to the provided differential equation with starting conditions of y = 40 and t = 0.

A mathematical statement that shows the equivalence of a couple of equations is what an equation at algebra means. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are split by the 'equal' symbol.

The given differential equation is:

dy/dt = 0.4(y - 200)

To solve this differential equation, we need to separate the variables and integrate:

dy/(y - 200) = 0.4 dt

Integrating both sides, we get:

ln|y - 200| = 0.4t + C

where C is the constant of integration.

To determine the value of C, we use the initial condition that y = 40 when t = 0:

ln|40 - 200| = 0.4(0) + C

ln|-160| = C

C = ln(160)

Thus, the equation becomes:

ln|y - 200| = 0.4t + ln(160)

Taking the exponential of both sides, we get:

|y - 200| = [tex]e^{(0.4t+ln(160))}[/tex] = 160[tex]e^{(0.4t)}[/tex]

Simplifying, we get:

y - 200 = ±160[tex]e^{(0.4t)}[/tex]

y = 200 ± 160[tex]e^{(0.4t)}[/tex]

Using the initial condition that y = 40 when t = 0, we can determine the value of the constant of integration:

40 = 200 ± 160[tex]e^{(0.4(0))}[/tex]

40 = 200 ± 160

Solving for the two possible values of y, we get:

y = 360 or y = 40

Therefore, the solution to the given differential equation with the initial condition y = 40 and t = 0 is:

y = 200 + 160[tex]e^{(0.4t)}[/tex]

The answer of the given question based on the scatterplot for determining  when she will reach 10,000 songs the answer is Maria will reach 10,000 songs in approximately 13.33 months, or about 14 months.

Slope is  measure of  steepness or incline of  line. In geometry and mathematics, slope is defined as  ratio of the change in  y-coordinates to  change in  x-coordinates between two distinct points on  line. This is often represented by  letter "m".

To determine when Maria will reach 10,000 songs, we need to find the point on the line of best fit where the y-value is 10,000.

From the scatterplot, we can estimate that the line of best fit intersects the y-axis at approximately 2000. This means that the initial number of songs downloaded was 2000.

Next, we need to find the slope of the line of best fit. Let's choose the points (5, 6500) and (10, 9500).

The slope of the line passing through these two points is:

slope = (y2 - y1)/(x2 - x1) = (9500 - 6500)/(10 - 5) = 600 songs per month

This means that Maria is downloading 600 songs per month on average.

Finally, we can use the slope-intercept form of a line to find the x-value when the y-value is 10,000:

y = mx + b

10,000 = 600x + 2000

8000 = 600x

x = 13.33

Therefore, Maria will reach 10,000 songs in approximately 13.33 months, or about 14 months.
