Step-by-step explanation:

Use triangle inequality theorem, which states

"The sum of the lengths of any two sides of a triangle is greater than the length of the third side."

The sum of two sides compared to the remaining side:

The sum of two sides is equal to the third side. This makes it impossible to make a triangle. Therefore the answer is no.

Yes, he can mow the lawn in 2 hours.

We can define the work done as, a work done in a given period of time.

Given that, Theo mows a lawn. After working for 1 3/5 hours, he has mowed 7/9 of the lawn

In \(1\frac{3}{5}\) hours he mows 7/9 part of lawn

Therefore, in 8/5 hours he is mowing 7/9 part of lawn

In 1 hour = 7/9*5/8 = 35/72

In 2 hours = 35/72*2 = 35/36 ≈ 1

Hence, Yes, he can mow the lawn in 2 hours.

Complete question is;

A group of biologists is surveying the mice population in a forest. The equation n=75⋅3t gives the total number of mice, n, t years since the survey began.

what does the number 3 mean in this situation.

1. the common difference

2. the total population

3. the common ratio

4. the slope

Answer:

3 is the common ratio

Step-by-step explanation:

We are given that the equation; n = 75⋅3^(t) gives the total number of mice, n, t years since the survey began.

Normally, formula when calculating population growth takes an exponential function;

n = n_o(e^(rt))

Or in this our case, it can be written as;

n = n_o((e^(r))^(t))

Comparing this with n = 75⋅3^(t), we can see that e^(r) = 3

Where r is the growth rate.

e is exponential constant.

Thus, we can say that 3 is the common ratio

The height of the candle after 7 hours is 20.9 centimeters.

Given that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning, we can find the equation of the linear function from the given information.

The given information can be tabulated as follows:

Time (hours)Height (centimeters)

After 5 hours 20.5 After 22 hours15.4

Let the height of the candle after x hours be y. Since the height of the candle is a linear function of the amount of time, we can use the slope-intercept form of the equation of a line to find the equation of the linear function, which is given by y = mx + b, where m is the slope and b is the y-intercept.

The slope of the line is given by \(m = (y₂ - y₁) / (x₂ - x₁)\)

Using the values of (x₁, y₁) = (5, 20.5) and

(x₂, y₂) = (22, 15.4),

we get m = (15.4 - 20.5) / (22 - 5)

= -5.1 / 17 = -0.3

Therefore, the equation of the line is y = -0.3x + b

Substituting the values of (x, y) = (5, 20.5),

we get

20.5 = -0.3(5) + b

=> b = 20.5 + 1.5 = 22

Substituting the values of m = -0.3 and b = 22 in the equation of the line, y = -0.3x + 22

Therefore, the height of the candle after 7 hours isy = -0.3x + 22

Substituting x = 7, we gety = -0.3(7) + 22= 20.9

Therefore, the height of the candle after 7 hours is 20.9 centimeters.

The balanced equation that represents an endothermic reaction is:

2 CH4 (g) + 2 O2 (g) → 2 CO2 (g) + 2 H2O (g)

This is because the reactants (CH4 and O2) have a higher bond energy than the products (CO2 and H2O), meaning that energy must be absorbed in order to break the bonds and form the products. As a result, the reaction is endothermic.

Step-by-step explanation:

To find coordinates, we need the equation of the line segment with restrictions. I think you meant to say “line segment” as lines go infinitely in 2 directions and could not be broken up into ratios. Let’s say your segment is 24 feet long. You could then label AB as 5x and BC as x since that is a ratio of 5:1 …………We’d then have an equation

5x + x = 24 … or 6x = 24…..or x = 4 which would make AB = 20 and BC = 4…but this would not give us coordinates of points.

According to the question The probability that the sample proportion of disapproval is greater than 0.55 is approximately 0.259.

In a random sample of 205 marketing professionals, 117 expressed disapproval of using ultraviolet ink on a mail survey. We want to determine the probability that the sample proportion of disapproval is greater than 0.55.

Assuming random sampling, independence, and a sufficiently large sample size, we calculate the sample proportion as 0.57. By computing the z-score and referring to a standard normal distribution table, we find that the probability of obtaining a z-score greater than 0.644 is approximately 0.259.

Hence, the probability that the sample proportion of disapproval is greater than 0.55 is approximately 0.259.

Main concepts

Concept 1. Congruent Triangles

Concept 2. Hypotenuse-Leg Congruence

Concept 3. Congruent Triangles implies congruent parts

Concept 4. Solving a one-variable equation

Concept 1. Congruent Triangles

For two triangles to be congruent, the three angles of one triangle must be congruent to the three angles of the other triangle, AND the three side lengths of one triangle must be congruent to the three side lengths of the other triangle.

Fortunately, through various proofs about different types of triangles, it isn't necessary to prove all six of those things.

The 5 cases of triangle Congruence are

Concept 2. Hypotenuse-Leg Congruence

Proving they are both right triangles, and that HL congruence can be used

In this situation, we are given that Angle UVT is a right angle.  Under the assumption that US is a line that contains V, then Angle UVT and Angle SVT form a linear pair and are supplementary (their measures add to 180 degrees).

So, Angle SVT is also a right angle.  This means that both Triangle UVT and Triangle SVT are Right Triangles, since they are each a triangle with a right angle.

To prove HL congruence, we need to prove that one leg of each triangle is congruent to the other, and that the hypotenuse of each triangle is congruent to the other.

Proving Hypotenuse congruence

Note that the Hypotenuse (side across from the right angle) of Triangle UVT is side UT with measure 67 units.

The Hypotenuse of Triangle SVT is side ST, also with measure 67 units.

So the Hypotenuses are congruent.

Proving Leg congruence

Note that one leg of the triangles is shared as a common side:  line segment VT is common to both triangles.  Even though we don't know the actual length of VT, the length of VT for the first triangle is the same as the length of VT for the second triangle.

The official reason that VT is congruent to VT is because of the "Reflexive property".  

Since the Hypotenuses and one leg from each triangle are congruent, the two triangle are congruent.  Specifically, Triangle UVT is congruent to Triangle SVT.

Concept 3. Congruent Triangles implies congruent parts

Even though we didn't prove all 6 congruences, we did prove that the triangles ARE congruent.  Therefore, all 6 congruences are true.  This means that any other pair of corresponding parts is also congruent.

Specifically, we're interested in the last pair of sides, because they have measurements that contain "b" the value we're trying to solve for.

Side UV is congruent to Side SV because Corresponding parts of Congruent triangles are Congruent.

This means that their lengths are equal:

\(Length_{UV}=Length_{SV}\)

\(b+24=2b\)

Concept 4. Solving a one-variable equation

For any equation in math where there is only one item that is unknown, (even if it shows up multiple times in the equation), there are two main steps:

Step 1.  Get the variable to show up exactly once

Step 2.  Isolate the variable

Step 1.  Get the variable to show up exactly once

Since we know that in the very end, we want b=__, we know that the b will appear only once (and thus only on one side of the equation, not both), and will be by itself.

In practice, sometimes there are special tricks that have to be employed to make this step happen.  Generally, this means simplify each side of the equation, and try to group like terms together.

For this equation, observe that b appears twice: once on the left side of the equation, and once on the right side of the equation.  

At some point, we'll need to get the "b"s on the same side of the equation, and hopefully combine like terms into a single term with b.

To get the "b"s on one side, we'll subtract b from both sides:

\((b+24)-b=(2b)-b\)

On the left, the positive b and negative b cancel completely, leaving just 24.  On the right, the 2b subtracted by 1b leaves just 1b, or more simply, b.

\(24=b\)

Step 2.  Isolate the variable

While trying to get the variable to show up exactly once, we also incidentally isolated the variable, as the like terms combined.

So, b=24.

To solve the problem, we need to set up a pairwise comparison matrix and determine the priorities for the soft drinks based on the flavor criterion. Then, we can compute the consistency ratio to determine if the individual's judgments are consistent.

(a) To set up the pairwise comparison matrix, we compare each flavor to the other two flavors and assign a score from 1 to 9 based on the degree of preference. In this case, each flavor is equally preferred, so we assign a score of 1 to each comparison.

(b) To determine the priorities for the soft drinks with respect to the flavor criterion, we use the eigenvector method. We calculate the average score for each flavor and divide it by the sum of all the scores. The resulting values represent the priorities for each flavor. In this case, the priorities for flavor A, B, and C are all 0.333.

(c) To compute the consistency ratio, we divide the consistency index by the random index. If the ratio is less than or equal to 0.1, the judgments are considered consistent. In this case, the consistency ratio is 0, which means the individual's judgments are consistent.

The pairwise comparison matrix and eigenvector method can help us determine the priorities for a set of criteria or alternatives. Additionally, the consistency ratio can help us assess the reliability of individual judgments.

Answer: x=36 and x=8

Step-by-step explanation:

For #10, the angle you need to solve for’s supplementary angle is a right angle. This means that the both of them added together equals 180°. The square marks it as a right angle, so 180°-90°=90°.
Now we have 3x-18=90, so we just solve it.

3x=90+18=108

x=36

For #11, the unlabeled angle is similar to #10 in that it is supplementary to a right angle, and is thus 90°. The angles with x in them make up a triangle with this 90°, and because a triangle’s angles add up to 180°, we can solve it like this:

180=90+3x+8x+2

11x=88

x=8

By substituting the given values into the formula and performing the calculations, we can determine the volume of the rectangular prism as a simplified mixed number. The volume is 1 cubic centimeter.

The formula for the volume of a rectangular prism is V = length × width × height.

In this case, the length of the rectangular prism is given as 20 cm, the width is 1214 cm, and the height is 1512 cm. Substituting these values into the formula, we have:

V = 20 cm × 1214 cm × 1512 cm

Calculating the product:

V = 36,691,680 cm³

To express the volume as a simplified mixed number, we can divide the total volume by the product of the length, width, and height.

36,691,680 cm³ ÷ (20 cm × 1214 cm × 1512 cm) = 1 cm³

Therefore, the volume of the rectangular prism is 1 cm³, expressed as a simplified mixed number.
