The table represents the description of the proportional relationship is Swiss Cheese (oz) 3 6 9 Cheddar Cheese (oz) 5 10 15

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Since the restaurant makes cheese sandwich with  3 oz of Swiss cheese and 5 oz of cheddar cheese.

Thus, the table that represents the proportional relationships will be the one that contains  3 oz of Swiss cheese with a corresponding value of 5 oz of cheddar cheese.

the constant of proportionality (k) must be the same (i.e. k = 5/3) for all the values.

Swiss Cheese (oz)     3  6   9

Cheddar Cheese (oz) 5  10 15

k = 5/3 = 10/6= 15/9 =5/3

Hence,  the table represents the description of the proportional relationship is Swiss Cheese (oz) 3 6 9 Cheddar Cheese (oz) 5 10 15

To hike a total of 11/6 miles, she would have to hike for 11 days. To hike a total of 1/3 of a mile, she would have to hike for 2 days.

She hikes 1/6 a day, to get 11/6 , she would have to hike 11 days

to hike 1/3 of a mile

1/3 / 1/6 = 1/3 * 6/1 = 6/3 = 2

so she would have to hike 2 days

To hike a total of 11/6 miles of distance in 11 days, the person would have to hike an average of 11/6 / 11 = 11/66 miles per day.

To hike a total of 1/3 of a mile in 2 days, the person would have to hike an average of 1/3 / 2 = 1/6 miles per day.

Thus, to hike a total of 11/6 miles, the person would have to hike for 11 days, and to hike a total of 1/3 of a mile, the person would have to hike for 2 days.

Using trigonometric ratio, the length of BE is 10 units, the value of sin B is 0.64 and cos B is 0.64 respectively

This is the ratio between the angles and sides of a right-angle triangle. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

In this problem, we have that

1)

Using tangent of B

tan B = opposite / adjacent

tan B = NE / BE

3/4 = 7.5 / BE

BE = 7.5 / 0.75

BE = 10

2)

To find sin B, we need to calculate the hypothenuse of the triangle which we will use Pythagoras's theorem

NB² = BE² + NE²

NB² = 10² + 7.5²

NB = 12.5

sin B = NE / NB

sin B = 7.5 / 12.5

B = sin⁻¹ (7.5 / 12.5)

B = 0.64

The number of permutations of two digits that we can write without 1 and 2 is 64 digits.

To find how many two digit numbers can be formed if we don't use 1 and 2, we find the number of permutations.

Permutations are the number of ways in which n objects can be arranged in x ways. It is given by ⁿPₓ = n!/x!

Now, since we require a two digit number without 1 and 2 in any of the digits, we have 10 digits - 2 digits = 8 digits.

So, we have 8 digits to arrange in both the first digit position and second digit position.

The number of permutations for the first digit is ⁸P₁ = 8.

The number of permutations for the second digit is ⁸P₁ = 8.

So, the total number of permutations for the two digit number is N = ⁸P₁ × ⁸P₁ = 8 × 8 = 64 ways

So, the number of digits that we can write without 1 and 2 is 64 digits.

The slope of the line is 2/3. It represents: b. When y increases by 2, x increases by 3.

The slope of a line can be described as the change in y over the change in x of the line, or the rise over its run.

The slope of a line is given as the value of "m", in the equation expressed in slope-intercept form as y = mx + b.

Given that a line has the equation, y = 2/3x + 5, in slope-intercept form, we can determine its slope (m), which is given as 2/3.

The value of m, which is 2/3, is the rise over the run of the line, which means that when the y value increases by 2, the x value increases by 3.

Therefore , the we need to pick n + 2 numbers  to be sure of random selection is an odd number.

In statistic, a simple random sample is a subset of people chosen at random from a larger group, all of whom were chosen with the same probability. This procedure involves choosing a sample at random.

Here,

You must choose n + 2 numbers at random in order to guarantee that you will get at least one odd number.

Since n is a positive integer, the following values of n are possible:

{1, 2, 3, 4, ...}

Let's assume n = 1.

Now, in order to guarantee that you choose at least one odd integer from 0 to 2n = 2*1 = 2, how many must you choose (at random)?

There are three numbers from 0 to 2:

0, 1, 2

If you choose these at random, selecting all three digits will guarantee that you receive an odd number.

From 0 to 2*n, there are the following options if n = 2.

0, 1, 2, 3, 4

Five choices.

If you wish to choose at least one odd number for certainty after picking 3 even numbers, you must choose 4 numbers.

From 0 through 2*n, if n = 3, we get:

0, 1, 2, 3, 4, 5, 6

Since 4 of these are even, you must choose 5 of them to guarantee an odd number.

The amount of even numbers is always n + 1, therefore given a random integer n, we will have n + 1 even numbers from 0 to 2n. Therefore, if we want to be certain that we are selecting an odd number at random, we must choose n + 2 numbers.

Answer:

  x > 90 > y

Step-by-step explanation:

You want to know the relationship of the central angles in a rectangle where the diagonals cross.

Assuming we can trust the figure (not always a good idea), we notice that x° is an obtuse angle and y° is an acute angle. (The angle opposite the longer side in this geometry will always be obtuse.)

This means ...

  x° > 90°

  90° > y°

The two angles form a linear pair, so their sum is 180°.

The correct description is ...

  x > 90 > y

Additional comment

If the diagonals crossed at right angles, the rectangle would be a square.

The required equation of a line is y = 9/5 (4x - 12)

Given-

The point from which the line passes through is (3,2)

The slope of the given line m is -4/5.

Equation of the line

The linear equation of a line can be represented by a set of points on a graph using the equation of the line.

The standard form of the line passing through the point x₁, y₁

The slope m is given by,

m = (y - y₁) / (x - x₁)

Put the values of points and slope in the above equation, we get,

-4/5 = (y - 2) / (x - 3)

-4/5(x - 3) = y -2

-4x/5 + 12/5 = y - 2

-1/5 (4x - 12) + 2 = y

y = 9/5 (4x - 12)

The linear equation of a line can be represented by a set of points on a graph using the equation of the line. The following equation depicts a line that crosses (3, 2) and has a slope of -4/5: y = 9/5 (4x - 12)

Answer:

x = 17

Step-by-step explanation:

x + 6 + 7x + 4 + 2x = 180  Combine like terms

10x + 10 = 180  Subtract 10 from both sides

10x = 170  Divide both sides by 10

x = 17

x = 17

1. Add the numbers

x + 6 + 7x + 4 + 2x = 180

x + 10 + 7x + 2x = 180

2. Combine like terms

x + 10 + 7x + 2x = 180

10x + 10 = 180

3. Subtract 10 from both sides

10x + 10 = 180

10x + 10 - 10 = 180 - 10

4. Simplify

Subtract the numbers:

10x + 10 - 10 = 180 - 10

10x = 180 - 10

Subtract the numbers:

10x = 180 - 10

10x = 170

5. Divide both sides by the same factor

10x = 170

[tex]\frac{10x}{10}[/tex] = [tex]\frac{170}{10}[/tex]

6. Simplify

Cancel terms that are in both the numerator and denominator:

[tex]\frac{10x}{10}[/tex] = [tex]\frac{170}{10}[/tex]

x = [tex]\frac{170}{10}[/tex]
