The amount for Emiliano tip is $1.8.

From the information, Emiliano buys two coffees for $8.98 and he tips the barista 20% of the bill.

The value of the tip will be:

= Percentage × Value of coffee

= 20% × $8.98

= 0.2 × $8.98

= $1.796

= $1.8 to the nearest cent.

The correct ratio of cherry halves to white grape halves in the mixture is 3:5.

The inspector noticed one jar has 12 cherry halves and 20 white grape halves. To fix this error, the food packing company should adjust the ratio of cherries to white grapes in the mixture.

Here's how to do it:

Let C be the number of cherry halves in the mixture and G be the number of white grape halves.

According to the given ratio, the proportion of cherry halves in the mixture is given by:

C / (C + G) = 3 / 11

To convert this proportion to a fraction, cross-multiply and simplify:

11C = 3(C + G)8C

= 3G

This means there are 3 white grape halves for every 8 cherry halves.

The total number of fruit halves in the mixture is:

C + G = (8/3)C

So for every 11 fruit halves, there are 8 cherry halves and 3 white grape halves.

Now consider the jar with 12 cherry halves and 20 white grape halves.

This means there are a total of 32 fruit halves in the jar.

To determine the correct number of cherry halves in the jar, use the ratio of cherry halves to fruit halves:

12 / 32 = 3 / 8

Solve for the number of cherry halves in the jar:

C = (12/32) * (8)

= 3

To determine the correct number of white grape halves in the jar, use the ratio of white grape halves to fruit halves:

20 / 32 = 5 / 8

Solve for the number of white grape halves in the jar:

G = (20/32) * (8)

= 5

The correct ratio of cherry halves to white grape halves in the mixture is 3:5.

Therefore, the company should adjust the mixture to add more white grape halves to future jars of fruit cocktail.

The sum of first 10 terms is 72.

Concept: Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value. It is also called Arithmetic Sequence.

Arithmetic Progression Formula

= an - a. nth term of an AP: an = a + (n - 1)d. Sum of n terms of an AP: Sn = n/2(2a+(n-1)d) = n/2(a + l), where l is the last term of the arithmetic progression.

Given:

Eighth term is 8.2

Common difference is 0.4

a(8) = 8.2

a + 7d = 8.2

Since d = 0.4

a + 7(0.4) =8.2

a = 5.4

Sum of 10 terms = n/2 (2a+(n-1)d)

= 5(2*5.4 + 9*0.4)

=5(10.8 +3.6)

Sum=72

This gives us the equation -2x + y = 0 and 4x - 3y = 0, which has the solution x = y/2. Therefore, the eigenvector for λ = 3 is v2 = [1; 2].

a) To find matrix A with eigenvalues 1 and 4 and corresponding eigenvectors v1 and v2 respectively, we can use the formula A = PDP^-1 where P is the matrix of eigenvectors and D is the diagonal matrix of eigenvalues.

We know that v1 and v2 are eigenvectors with eigenvalues 1 and 4 respectively, so we can set up the following equations:

Av1 = 1v1 and Av2 = 4v2

Multiplying both sides of each equation by P^-1, we get:

PDv1 = v1 and PDv2 = 4v2

Therefore, P = [v1 v2] and D = [1 0; 0 4], which gives us the matrix A = PDP^-1.

b) To find matrix B with eigenvalues 1 and 3, we can use the same formula A = PDP^-1. However, we don't know the eigenvectors yet. To find them, we can use the characteristic polynomial of B, which is (1-λ)(3-λ) = 0. This gives us eigenvalues λ = 1 and λ = 3.

To find the eigenvectors for λ = 1, we need to solve the equation (B-λI)v = 0, which gives us:

(B-1I)v = 0
[0 1; 1 2][x; y] = [0; 0]

This gives us the equation x + y = 0, so the eigenvector for λ = 1 is v1 = [1; -1].

To find the eigenvectors for λ = 3, we need to solve the equation (B-λI)v = 0, which gives us:

(B-3I)v = 0
[-2 1; 4 -3][x; y] = [0; 0]


Using these eigenvectors and the formula A = PDP^-1, we can find the matrix B = PDP^-1 where P = [v1 v2] and D = [1 0; 0 3].

The best answer regarding the effects of carbon monoxide is option c, CO results in less oxygen loading hemoglobin but unloading is not changed.

Carbon monoxide binds up more tightly to the hemoglobin as compared to the oxygen molecules. This reduces the oxygen-carrying capacity of the blood and results in less oxygen loading onto hemoglobin.

However, once oxygen is already bound to hemoglobin, CO does not significantly affect its release or unloading. Therefore, option c is the most accurate statement among the given choices.

Answer:

41 inches of wire will cost 164 cents.

Step-by-step explanation:

1st Method

Use proportions!

18/ 72 = 41/ c

Cross multiply

18 * c = 72 * 41

18c = 2952 divide both sides by 18

c = 164

2nd Method.

Find the rate of the costs. r = rate

18*r = 72

r = 4 cents/inch

Now that you've found the rate you can multiply it by 41 inches to find the cents the wire costs!

41 inch * r (cents/inch)          inches cancels out.

41 * 4 = 164

164 cents

As a result, the following must be true regarding trapezoids is A) One pair of opposite sides is parallel.

What does math parallel mean?

Lines inside a plane which are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.

Option A: One pair of opposite sides is parallel is true for all trapezoids. This is the defining characteristic of a trapezoid.

Option B: Opposite angles are equal is not necessarily true for all trapezoids. Only isosceles trapezoids have opposite angles that are equal.

Option C: Opposite sides are equal is not necessarily true for all trapezoids. Only isosceles trapezoids have opposite sides that are equal.

Option D: Both pairs of opposite sides are parallel is not necessarily true for all trapezoids. This only occurs in a special type of trapezoid known as a parallelogram.

The most effective graphical representation of the above data would be a histogram.

A histogram is a graphic representation of the distribution of numerical data. In this case, data on the carbohydrate content of ten different tortilla sandwich wraps is acquired. The best option is a histogram because the data is numerical.

For categorical data, which is broken up into several categories and displayed as a fraction or percentage of the whole, a circle chart, also known as a pie chart, is the best option. The information offered is numerical rather than categorical, though.

Each individual data point is shown as a dot on a number line in a dot plot, also called a line plot. It may not be suitable for larger quantities of data, although being advantageous for an.

Numerical data can be arranged and displayed using a stem-and-leaf plot. For just ten data points, it might not be the ideal depiction, though.

Therefore, the most appropriate graphical representation for the provided data would be a histogram.
