An equation for the relationship between time and distance for each horse include the following;

horse A; y = 1/4(x).

horse B; y = 5/2(x).

In Mathematics and Geometry, a proportional relationship is a type of relationship that passes through the origin (0, 0) and produces equivalent ratios as represented by the following mathematical equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) for each horse by using various data points as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k of A = 1/4 = 8/2

Constant of proportionality, k of B = 5/2 = 10/4.

Therefore, the required linear equation for horse A is given by;

y = kx

y = 1/4(x)

Also, the required linear equation for horse A is given by;

y = kx

y = 5/2(x)

Answer:

Your tip was $6.11.

Step-by-step explanation:

You worked the dinner shift tonight and served a family their dinner.

The bill was $43.89. They left $50 to pay for the meal.

So, the remaining difference was your tip.

The remaining balance = [tex]50-43.89=6.11[/tex] dollars

Therefore, your tip was $6.11.

A(t) = P(1+(r/n))^(nt)

A(5) = 1000(1+0.12/2)^(2*5)

A(5) = 1000(1.06)^(10)

A(5) = $1790.85

1000 x 6%= 1000 x .06

1000 x .06 =  60

The principal is getting $60 every year for their annual interest rate.

Answer:

-8

Step-by-step explanation:

Given that x and y are two variables.  they are related by the function

y =8-2x

Since x and y are related, given one value we can find the other using this equation.

In our question, given that x =8

Substitute x value in the equation

y = 8-2x

y =8-2(8) = -8

Hence answer is -8:

Verify:  We verify by putting -8 for y and check whether x =8

-8=8-2x

Or 2x = 16

x =8

The probability of obtaining a grade of 'B' in the given science class, using the concept of conditional probability, is 0.320.

To find the probability of getting a grade of 'B' given that it's a science class, also known as conditional probability, we can use the following formula:

P(grade of B | science class) = (number of students with a 'B' in science) / (total number of students in the science class).

When we apply the given numbers from the tables:

(Number of students with B in science class) = 8

(Total number of Students in the science class) = (A=5) + (B=8) + (C=10) + (D=1) + (F=1) = 25

Substituting the obtained numbers in our formula, we find:

P(grade of B | science class) = 8 / 25 = 0.320

So, the probability of getting a grade of 'B' given that it's a science class is 0.320. Therefore, the answer is O 0.320.

Answer:

amount remaining = 1.483  kg

Step-by-step explanation:

According to the question Ming weighed the bag of soil for a science experiment. He discovered the weight was 2.003 kg . She then removed 0.520 kg of soil from the bag she weighed initially.

The amount in weight(kg) of soil that is remaining in the bag will be the initial weight minus the amount of weight she removed .

amount remaining = initial weight - amount removed

initial weight = 2.003 kg

amount removed = 0.520 kg

amount remaining = 2.003 - 0.520

amount remaining = 1.483  kg

The Contrapositive of the statement 'If two triangles are congruent, then their corresponding angles are congruent' is: If the corresponding angles of two triangles are not congruent, then the triangles are not congruent.

The contrapositive of the statement 'If two triangles are congruent, then their corresponding angles are congruent' is:

If the corresponding angles of two triangles are not congruent, then the triangles are not congruent.

The contrapositive of a conditional statement exchanges the hypothesis and conclusion, and negates both.

In this case, we negate the hypothesis 'two triangles are congruent' and the conclusion 'their corresponding angles are congruent.'

A container has 17 and 1/2 cups of lemonade.

Asher gives each of his classmates 5/6 of a cup.

He gives away all of the lemonade.

Solution:

There are 17.5 cups of lemonade.

Each classmate receives 5/6 of a cup.

So the number of classmates = Number of cups ÷  proportion of a cup each student receives

Number of classmates = 17.5 ÷ 5/6 = 21 classmates

There are 21 classmates.

Answer:

21 classmates.

Step-by-step explanation:

We have been given that a container has 17 1/2 cups of lemonade. Asher gives each of his classmates 5/6 of a cup.

To find the number of classmates that will get lemonade, we will divide total amount of lemonade by amount given to each classmate.

[tex]\text{Classmates that will get lemonade}=17\frac{1}{2}\div\frac{5}{6}[/tex]

Convert mixed fraction into improper fraction:

[tex]17\frac{1}{2}\Rightarrow=\frac{17\times 2+1}{2}=\frac{34+1}{2}=\frac{35}{2}[/tex]

[tex]\text{Classmates that will get lemonade}=\frac{35}{2}\div\frac{5}{6}[/tex]

Convert into multiplication problem by flipping the 2nd fraction:

[tex]\text{Classmates that will get lemonade}=\frac{35}{2}\times\frac{6}{5}[/tex]

[tex]\text{Classmates that will get lemonade}=\frac{7}{1}\times\frac{3}{1}[/tex]

[tex]\text{Classmates that will get lemonade}=7\times3[/tex]

[tex]\text{Classmates that will get lemonade}=21[/tex]

Therefore, Asher gave lemonade to 21 classmates.

After applying the dilation with a scale factor of 3/4, point B at (4,-16) will transform to B prime (B') at (3,-12).

The point B is originally at (4,-16). In a dilation, each coordinate of the initial point is multiplied by the scale factor to obtain the coordinates of the transformed point. Here, the scale factor is 3/4. To find the coordinates of the point B prime (B') after the dilation, we multiply each coordinate of point B by 3/4:

X-coordinate of B' = 4 * (3/4) = 3

Y-coordinate of B' = -16 * (3/4) = -12

Therefore, the coordinates of B prime (B') after the dilation with a scale factor of 3/4 are (3, -12).

ANSWER

QUESTION 17a

We were given the relation, [tex]y=15x[/tex], where y represents the number of new vocabularies learned, and x represents the number of weeks

Draw a horizontal line for number of weeks and a vertical line for number of vocabulary words using a scale of 5 units on both axes.

To graph this equation we need at least three points,

When

[tex]x=0[/tex], [tex]y=15(0)[/tex], [tex]\Rightarrow y=0[/tex]

So we plot the point [tex](0,0)[/tex]

When

[tex]x=1[/tex], [tex]y=15(1)[/tex], [tex]\Rightarrow y=15[/tex]

So we plot the point [tex](1,15)[/tex]

When

[tex]x=2[/tex], [tex]y=15(2)[/tex], [tex]\Rightarrow y=30[/tex]

So we plot the point [tex](2,30)[/tex]

Using a straight edge we draw a straight line through these three points.

The equation of the line is of the form [tex]y=mx[/tex], where [tex]m=15[/tex] is the slope.

This tells us that the 15 new vocabulary words are learned each week.

QUESTION 17 B

To find the number of new vocabulary words learnt after 5 weeks, we plug in [tex]x=5[/tex] in to the equation.

[tex]y=15(5)[/tex]

This gives us

[tex]y=75[/tex]

Therefore after 5 weeks, you learn 75 new vocabulary words.

QUESTION 17 C

We  find the number of vocabulary words learned after 4 weeks and subtract it from the number of vocabulary words learned after 6 weeks'

To find the number of new vocabulary words learnt after 4 weeks, we plug in [tex]x=4[/tex] in to the equation.

[tex]y=15(4)[/tex]

This gives us

[tex]y=60[/tex]

Therefore after 4 weeks, you learn 60 new vocabulary words.

To find the number of new vocabulary words learnt after 6 weeks, we plug in [tex]x=6[/tex] in to the equation.

[tex]y=15(6)[/tex]

This gives us

[tex]y=90[/tex]

Therefore after 6 weeks, you learn 90 new vocabulary words.

We now subtract to get

[tex]90-60=30[/tex]

Therefore you learn 30 more vocabulary words after 6 wees than after 4 weeks.

The given equation y=15x + 17 represents the number of new vocabulary words you learn every week. Here, you learn 15 new words each week. You already know 17 words at the start (when x=0).

The question is asking for the interpretation of the equation y=15x + 17, which represents the number of new vocabulary words, y, that you learn after x weeks. Here, 15 is the coefficient of x, which means that you learn 15 new words per week. The number 17 is the constant term, implying that even without any weeks passing (when x=0), you already know 17 words. Thus, after one week, you would know 15*1 + 17 = 32 words, after two weeks, 15*2 + 17 = 47 words, and so on.
