The greatest amount that a person can receive is 19$. Option D

A word problem is a mathematical exercise which is in the form of a hypothetical question that needs mathematical analysis and equations to be solved.

Total amount = $30

Total number of people = 8

According to the problem, each person gets at least 1$ and also exact amount.Let's consider only one person gets more than 5$ because, we have to find the greatest value.

4 people get more than 1$,that includes the person who gets the maximum amount.

Let the person who gets maximum amount =x

x + 2+2+2+1+1+1+1

Maximum amount = 30- (2+2+2+1+1+1+1+1)= 11$

Answer: We use the SSS

Step-by-step explanation:

SSS method or Side Side Side method is when we test to see if the triangles are the same or not. We know this by checking if the sides of the triangles change at the same rate or not!

Let test the YW is 4 and the WY is 8, we see the side multiply by 2

The VX is 5 and the XZ is 10, wee see the sided multiply by 2

So we use the SSS to show that both triangles are equal

The weight of the baby at the end of the 8 months was 18.125lbs.

The weight of baby at birth = 7.25 lb

At the end of 8 months, the baby weighed 2.5 times its birth weight.

We need to find the weight of the baby at the end of 8 months.

[tex]\frac{2}{5}[/tex] = [tex]\frac{4+1}{2}[/tex] = [tex]\frac{5}{2}[/tex]

The weight of the baby at the end of 8 months is 5/2 times of its initial weight.

Total weight = 7.25 x [tex]\frac{5}{2}[/tex]

Total weight = 18.125

Therefore, the weight of baby at the end of 8 month is 18.125 lbs.

Answer:

the first company would be cheaper because it has a lower total cost.

Step-by-step explanation:

To determine which company is more cost-effective, you will need to compare the total costs for each company based on the amount of sugar being transported.

If the first company is used, the total cost for transporting x tons of sugar will be 3204 + 75.25x dollars.

If the second company is used, the total cost for transporting x tons of sugar will be 275.50x dollars.

To determine which company is cheaper for a given amount of sugar, you can compare these two equations by setting them equal to each other and solving for x.

For example, if you want to transport 100 tons of sugar, you can set the two equations equal to each other and solve for x:

3204 + 75.25x = 275.50x

Solving for x, we get: x = 3204 / (75.25 - 275.50) = 107.8 tons

This means that if you want to transport 100 tons of sugar, the first company would be cheaper, because it costs less than the second company for any amount of sugar greater than 107.8 tons.

If you want to transport a different amount of sugar, you can repeat this process to determine which company is cheaper.

For instance, if the multiplication error is 8 x 7 = 56, then the matching division error  56/8 = 7, demonstrating that the result of the division is the other component that was used in the multiplication.

Finding the product of two or more corresponding integers is done mathematically through the action of multiplication. It is frequently represented by the letters "x" or "*." In order to discover the result of multiplication, a multiplicand, also known as the multiplicand, is multiplied by a multiplier, also known as the multiplier. The result of the two integers, for instance, is 56 if the multiplicand and multiplier are both 8. A multiplication process always yields a greater number as the outcome than either of the initial factors. Multiply is also used to describe the process of adding a number to itself a certain number of times, as in "7 multiplied by 3 equals 21."

Answer:

[tex]\textsf{A)} \quad -1\dfrac{3}{20}y+4[/tex]

Step-by-step explanation:

Given expression:

[tex]\left(11-9 \dfrac{3}{5}y\right)+\left(8 \dfrac{9}{20}y-7 \right)[/tex]

Remove the parentheses:

[tex]11-9 \dfrac{3}{5}y+8 \dfrac{9}{20}y-7[/tex]

Collect like terms:

[tex]8 \dfrac{9}{20}y-9 \dfrac{3}{5}y+11-7[/tex]

Subtract the numbers 11 - 7:

[tex]8 \dfrac{9}{20}y-9 \dfrac{3}{5}y+4[/tex]

Factor out y:

[tex]\left(8 \dfrac{9}{20}-9 \dfrac{3}{5}\right)y+4[/tex]

Partition the mixed numbers into fractions and whole numbers, and then subtract them separately.

Subtract the whole numbers:

[tex]\implies 8-9=-1[/tex]

Subtract the fractions by changing both fractions into equivalent fractions so both fractions have the same denominator:

[tex]\implies \dfrac{9}{20}-\dfrac{3}{5}[/tex]

[tex]\implies \dfrac{9}{20}-\dfrac{3 \cdot 4}{5 \cdot 4}[/tex]

[tex]\implies \dfrac{9}{20}-\dfrac{12}{20}[/tex]

[tex]\implies -\dfrac{3}{20}[/tex]

Put the two answers from the whole numbers and fractions back together:

[tex]\implies -1-\dfrac{3}{20}=- \left(1+\dfrac{3}{20}\right)=-1\dfrac{3}{20}[/tex]

Therefore:

[tex]\left(8 \dfrac{9}{20}-9 \dfrac{3}{5}\right)y+4=\left(-1\dfrac{3}{20}\right)y+4=-1\dfrac{3}{20}y+4[/tex]

The measure of angle A and angle B is equal to 70° as per the given relation of both the angles.

As given in the question,

Given measure of angle A is equal to ( 8x + 6 )°

Given measure of angle B is equal to ( 4x + 38 )°

Given condition :

Measure of both the angles are equal to each other

Measure of ∠A = Measure of ∠B

⇒ ( 8x + 6 )° =  ( 4x + 38 )°

Now simplify the above equation to get the value of x

⇒(8x - 4x)° = (38 -6)°

⇒4x°= 32°

⇒x = 32°/4

⇒x = 8°

Measure of ∠A = 8(8) + 6

                         = 70°

Measure of ∠B = 4(8) +38°

Answer:

  A:) T(t) = 305(230/305)^(t/10) +70

  B:) T(20) ≈ 243.4 °F

Step-by-step explanation:

You have a pie removed from a 375° oven to a room temperature of 70° that has cooled to 300° after 10 minutes. You want to know its temperature after 20 minutes.

Newton's law of cooling tells you the rate of change of an object's temperature is proportional to the difference between the object's temperature and that of its surroundings. The differential equation describing this has an exponential function as its solution. That exponential function can be written as ...

  temperature = (initial temperature difference)·(cooling factor)^(time/(cooling time)) + (final temperature)

Here, the initial temperature difference between the pie and room temperature is ...

  initial temperature difference = 375° -70° = 305°

The final temperature is the room temperature:

  final temperature = 70°

The cooling factor is the multiplier applied to the temperature difference in the time period "cooling time". Here, the pie is at 300°, a temperature difference of 300° -70° = 230° after a cooling time of 10 minutes. The cooling factor is ...

  cooling factor = 230/305

These values let us write the equation as ...

  T(t) = 305(230/305)^(t/10) +70

The temperature after 20 minutes is found using this equation:

  T(20) = 305(230/305)^(20/10) +70 = 305(46/61)^2 +70 = 243 27/61

  T(20) ≈ 243.4 . . . . degrees F

__

Additional comment

The cooling factor can be expressed as a value that lets the exponent be t. Often, it is written as (e^k), where ...

  k = 1/10·ln(230/305) ≈ -0.0282232

Then the equation is ...

  T(t) = 305·e^(-0.0282232t) +70

It could also be written as ...

  T(t) = 305(0.972171^t) +70

where 0.972171 = (46/61)^(1/10).

You can use scatter plots to present bivariate data. The data can be used to create coordinate pairs.

The relationship between the two variables in a bivariate data set is graphically represented by a scatter plot. Consider them to be the graphic depiction of two data sets that have been combined by allocating each axis in the plot to a distinct variable.

Due to the presence of two variables, this type of data is known as bivariate data. Only 1 variable may be displayed on a line plot. You can use scatter plots to present bivariate data. The data can be used to create coordinate pairs.

The standard deviation of each variable and the covariance between them must first be determined in order to calculate the Pearson correlation. Covariance is subtracted from the product of the standard deviations of the two variables to get the correlation coefficient.

As we can see from the picture, the line has a negative slope of 1 (we can also just say -1). We know this is the slope because it has a rise of -1 and a run of -1. (I hope that made sense lol :/)

[Side note, we use x instead of 1.]

The y-intercept is -4 since we can see the line passes through the y-axis at -4.
