Assumming the y intercept is at 0,20, the slope is \(\frac{1}{3}\)

Step-by-step explanation: \(\frac{36-26}{50-20}\) = \(\frac{10}{30}\) = \(\frac{1}{3}\)

Using the slope formula the rate of change of the volume of the gas sample with respect to the temperature is \(\frac{1}{3}\).

What is the slope?

A rising or falling surface is one that has one end or side that is higher than the other.

It is given that from the graph, the given line passes through the points (20,26) and (50,36).

Knows the slope of the line which passes through the points \((x_1, y_1)\) and \((x_2,y_2)\).

Therefore, the rate of change of the volume of the gas sample with respect to the temperature

\(& \Rightarrow \text{Slope}=\frac{36-26}{50-20} \\ & \Rightarrow \text{Slope}=\frac{10}{30} \\ & \Rightarrow \text{Slope}=\frac{1}{3} \\\)

Therefore, using the slope formula the rate of change of the volume of the gas sample with respect to the temperature is \(\frac{1}{3}\).

Answer & Step-by-step explanation:

This is a proportion. To solve it, we need to set up the equation.

___________________________________________________Step 1: Set up the Proportion

The proportion here needs to be expressed as:

\(\frac{pink flowers}{white flowers}\)

Since this ratio is 3/2, we can set up the proportion as follows:

\(\frac{3}{2} =\frac{a}{36}\)

___________________________________________________Step 2: Use Cross-Multiplication

2a = 3 × 36

3a = 216

a = 72___________________________________________________Step 3: Repeat for the Other Values

\(\frac{3}{2} = \frac{72}{b}\)

3b = 2 × 72

3b = 144

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

X = 2.5

The answer is the cost per steak at store one is .75 less than the steak at store 2

Explanation: the top tells you that the steak at store one is $6.75 a pound. The chart tells you 2 steaks is $15 in store 2 so if you do 15/2 you get $7.5 for the cost of one steak.

To figure out the cost difference just do 7.5-6.5 which is 0.75 so the cost of steaks at store 1 is .75 less than the cost of steaks at store 2.

Solving the Question

We're given:

There were 478 people in total.$1.75 per child$2.25 per adultTotal revenue of $975We must find the number of children and adults who swam.

Set variables:

Let a represent the number of children who swam.

Let b represent the number of adults who swam.

Create equations

Because we've set two variables, we need two equations to be able to find the answers.

One of the equations will regard price while the other will regard the number of people, as those are the two things given in the question.

Number of people:

\(a+b=478\)

The number of children + the number of adults = 478 in total

Price:

\(1.75a+2.25b=975\)

$1.75 per child + $2.25 per child = $975 in total

Solve equations\(a+b=478\)\(1.75a+2.25b=975\)

We can solve this question using substitution, where we plug one equation into the other.

Isolate a in the first equation:

\(a+b=478\\a=478-b\)

Plug the first equation into the second equation by replacing a:

\(1.75a+2.25b=975\\1.75(478-b)+2.25b=975\)

Solve for b:

\(1.75(478-b)+2.25b=975\)

⇒ Open up the parentheses:

\(836.5-1.75b+2.25b=975\\836.5-0.5b=975\)

⇒ Subtract 836.5 from both sides to isolate b:

\(-0.5b=138.5\)

⇒ Divide both sides by -0.5:

\(b=277\)

Therefore, there were 277 adults in total.

Solve for a:

\(a+b=478\)

⇒ Replace b with 277:

\(a+277=478\\a=201\)

Therefore, there were 201 children in total.

Answer

There were 201 children and 277 children at the pool that day.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)

Answers

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

C 3737
D 1313
E 17

Answers

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

16
2+3+5+9+17+22+31+39=128
128/8=16

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?

Answers

C(7, 4) = 7! / (4!(7-4)!) = (7 * 6 * 5) / (3 * 2 * 1) = 35

and

C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287

Multiply these two combinations since the faculty members and students are selected independently:

Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045

Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
To determine the number of ways to form the committee with 4 faculty members and 5 students, we need to calculate the combinations of faculty members and students separately and then multiply them together.

For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:

C(7, 4) = 7! / (4!(7 - 4)!) = 35.

So, there are 35 ways to select 4 faculty members from the 7 eligible ones.

For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:

C(13, 5) = 13! / (5!(13 - 5)!) = 1287.

Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.

To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:

35 * 1287 = 44,895.

Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.
