Find the measure of one interior angle in each regular polygon. Round your to nearest tenth if necessary.

Answer:

{-6, -5, -4, -3, -2, -1}.

Step-by-step explanation:

The set contains the integer -6  ( because of the ≤ )  but not 0 because of the < 0.

Answer:

Step-by-step explanation:

Time taken = 9.77/100 = 0.0977 seconds

The 3 inside angles need to equal 180.

Subtract E from 180 to find the sum of the other two angles:

180 - 104 = 76

Now because EF ≅ DE , angle D and F would be the same so divide 76 by 2

Angle D = 38

Final answer:

The weight of each bag of equal weight is 1 17/20 kg and the weight of the third bag is 1 41/20 kg.

Explanation:

Let's assume the weight of each bag of equal weight is x kg. According to the question, the third bag is heavier than each of the equal bags by 1 1/5 kg, which can be written as 6/5 kg.

So, the weight of the third bag is x + 6/5 kg.

Now, we can set up an equation based on the given information:

2x + (x + 6/5) = 6 3/4

Simplifying the equation, we get:

3x + 6/5 = 27/4

Now, we can solve for x by multiplying both sides of the equation by 5 to get rid of the fraction:

15x + 6 = 135/4

15x = 135/4 - 6

15x = 135/4 - 24/4

15x = 111/4

Now, divide both sides of the equation by 15 to solve for x:

x = (111/4) / 15 = 111/60 = 37/20 = 1 17/20

Hence, the weight of each bag of equal weight is 1 17/20 kg and the weight of the third bag is 1 17/20 + 6/5 = 1 17/20 + 24/20 = 1 41/20 kg.

Answer:

  13/10

Step-by-step explanation:

13/10 = 1.30 is a number between 1.25 and 1.50.

Answer:

∠CIS.

Step-by-step explanation:

This angle is opposite from the smallest side. Therefore, according to the triangle inequality, it is the smallest angle.

The smallest angle that the angular momentum vector can make with the z-axis for an electron with quantum number l=2 is found using the magnetic quantum numbers. For m₁=+2, the angle would be the smallest, approaching 0 degrees.

The question pertains to the calculation of the smallest angle that the angular momentum vector ℓ can make with the z-axis given the quantum number l for an electron. To find this, we use the concept of quantized angular momentum in quantum mechanics.

For an electron with a quantum number l=2, it can have multiple magnetic quantum numbers m₁, ranging from -l to +l. Therefore, for l=2, m₁ can be -2, -1, 0, 1, or 2. Each of these values corresponds to a different angle with the z-axis.

The smallest angle corresponds to the maximum value of m₁, which is 2 in this case. The formula cos 0 = Lz/L uses the magnetic quantum number m₁ and the total angular momentum to calculate the cosine of the angle. For m₁=+1, the value of cos 0 would be 0.707, using the provided ratios and simplifying the formulas given. This corresponds to an angle whose cosine is 0.707, which through the inverse cosine function can be determined to be approximately 45 degrees. However, for m₁=+2, the angle would be even smaller, approaching 0 degrees as the z-component of angular momentum becomes maximally aligned with the z-axis.

Answer:

67000*.15=10,050

Step-by-step explanation:

The required down payment would be the amount of $10,050.

The percentage is defined as a ratio expressed as a fraction of 100.

Anna wants to buy a house for $67,000.

She will need a down payment of 15%.

We have to determine the evaluation of 15% of $67,000.

⇒ 15% of 67,000

15%  is expressed as 15/100 in fractional form

⇒ (15/100)(67,000)

15/100  is expressed as 0.15 in decimal form

⇒ (0.15)(67,000)

Apply the multiplication operation, and we get

⇒ 10,050

Therefore, the down payment would be $10,050.

The width of rectangle is [tex]2\frac{1}{4}\ cm[/tex] and length is [tex]5\frac{5}{12}\ cm[/tex]

Step-by-step explanation:

Let,

Width of rectangle = w

Length of rectangle = w+[tex]3\frac{1}{6}=w+\frac{19}{6}[/tex]

Perimeter of rectangle = [tex]15\frac{1}{3}=\frac{46}{3}\ cm[/tex]

Perimeter of rectangle = 2(Length + Width)

[tex]2(w+\frac{19}{6}+w)=\frac{46}{3}\\2(2w+\frac{19}{6})=\frac{46}{3}\\4w+\frac{19}{3}=\frac{46}{3}[/tex]

Subtracting [tex]\frac{19}{3}[/tex] from both sides

[tex]4w+\frac{19}{3}-\frac{19}{3}=\frac{46}{3}-\frac{19}{3}\\4w=\frac{46-19}{3}\\4w=\frac{27}{3}\\4w=9[/tex]

Dividing both sides by 4

[tex]\frac{4w}{4}=\frac{9}{4}\\w=\frac{9}{4}[/tex]

Therefore,

Width of rectangle = w = [tex]\frac{9}{4}=2\frac{1}{4}[/tex] cm

Length of rectangle = [tex]w+\frac{19}{6}=\frac{9}{4}+\frac{19}{6}=\frac{27+38}{12}=\frac{65}{12}=5\frac{5}{12}\ cm[/tex]

The width of rectangle is [tex]2\frac{1}{4}\ cm[/tex] and length is [tex]5\frac{5}{12}\ cm[/tex]

Question 3

-----------

Explanation:

Note how in choice A we have repeated x values

x = 3 pairs up with y = 4 and y = 5 at the same time.

The input x = 3 must only pair up with one output only if we want a function to happen.

If you plotted the points (3,4) and (3,5), it is possible to draw a vertical line through them. So this fails the vertical line test.

The other answer choices do not have repeated x values, so they are all functions.

==========================================

Question 4

-----------

If you plotted choice A and choice D on an xy coordinate system, you should see straight lines forming.

2x+3y = 10 turns into y = (-2/3)x+10/3 which is y = mx+b form.

Choice D's equation is equivalent to y = 0x+18, so its slope here is 0, making it a flat horizontal line.

Choice B does not count as an answer because while it is a linear vertical line, it is not a function for similar reasons back in question 3. The fact that x = 16 pairs up with infinitely many y values is what makes this not be a function.

Choice C is not a linear equation. Instead it is a quadratic equation because the largest exponent is 2.

The quotient is [tex]\frac{3(y-5)}{2}[/tex]

Explanation:

The expression is [tex]\frac{2 y^{2}-6 y-20}{4 y+12} \div \frac{y^{2}+5 y+6}{3 y^{2}+18 y+27}[/tex]

Now, reciprocal the term [tex]\frac{y^{2}+5 y+6}{3 y^{2}+18 y+27}[/tex] and convert ÷ to ×

[tex]\frac{2 y^{2}-6 y-20}{4 y+12} \times \frac{3 y^{2}+18 y+27}{y^{2}+5 y+6}[/tex]

Taking the common terms out, we get,

[tex]\frac{2\left(y^{2}-3 y-10\right)}{4(y+3)} \times \frac{3\left(y^{2}+6 y+9\right)}{y^{2}+5 y+6}[/tex]

Factorizing each numerator and denominator, we get,

[tex]\frac{2(y-5)(y+2)}{4(y+3)} \times \frac{3(y+3)(y+3)}{(y+3)(y+2)}[/tex]

Multiplying the terms, we have,

[tex]\frac{6(y-5)(y+2)(y+3)^{2}}{4(y+3)^{2}(y+2)}[/tex]

Cancelling the common factors, we get,

[tex]\frac{3(y-5)}{2}[/tex]

Thus, the quotient is [tex]\frac{3(y-5)}{2}[/tex]

[tex]\left[\begin{array}{ccc}-25&\dfrac{75}{2}&-\dfrac{25}{2}\end{array}\right][/tex]

Step-by-step explanation:

In the first equality

[tex]5\times \left[\begin{array}{cc}-1&2\\4&8\end{array}\right] =\dfrac{2}{5}m\times \left[\begin{array}{cc}-1&2\\4&8\end{array}\right],[/tex]

the matrices in both parts are the saem. The equality will be true if the same matrices are multiplied by the same numbers, so

[tex]5=\dfrac{2}{5}m\Rightarrow m=5\times \dfrac{5}{2}=\dfrac{25}{2}[/tex]

For the second equality

[tex](H+[1\ 4\ -2])+[3\ 2\ -6]=[-2\ 3\ -1]+([1\ 4\ -2]+[3\ 2\ -6]),[/tex]

if [tex]H=[-2\ 3\ -1][/tex], then this equality represents the assotiative property of matrix addition.

Hence,

[tex]m\times H=\dfrac{25}{2}\times [-2\ 3\ -1]=\left[\begin{array}{ccc}-25&\dfrac{75}{2}&-\dfrac{25}{2}\end{array}\right][/tex]

Answer:

The nth term of the given arithmetic sequence is [tex]a_n=-17+(n-1)9[/tex]

Step-by-step explanation:

Given sequence is -17,-8,1,...

To find the nth term of the given sequence :

Let  [tex]a_1=-17,a_2=-8,a_3=1,...[/tex]

To find the common difference d :

[tex]d=a_2-a_1[/tex]

[tex]=-8-(-17)[/tex]

[tex]=-8+17[/tex]

Therefore d=9

[tex]d=a_3-a_2[/tex]

[tex]=1-(-8)[/tex]

[tex]=1+8[/tex]

Therefore d=9

The common difference d is 9

Therefore the given sequence is an arithmetic sequence

The nth term of an arithmetic sequence is given below

[tex]a_n=a_1+(n-1)d[/tex]

Substitute [tex]a_1=-17[/tex] and d=9 in the above equation we get

[tex]a_n=-17+(n-1)9[/tex]

Therefore the nth term of the given arithmetic sequence is [tex]a_n=-17+(n-1)9[/tex]

The formula for the nth term of the sequence -17, -8, 1 is a_n = 9n - 26, where n is the position of the term in the sequence.

The sequence provided is -17, -8, 1, which suggests that there is a common difference between terms since it is an arithmetic sequence. To find the nth term of an arithmetic sequence, we use the formula a_n = a_1 + (n - 1)d, where a_n is the nth term, a_1 is the first term, and d is the common difference. In this case, the common difference is 9 (since -8 - (-17) = 9).

So, using the formula for the nth term of an arithmetic sequence:

Our formula becomes a_n = -17 + (n - 1) × 9. Simplifying this:

a_n = -17 + 9n - 9

a_n = 9n - 26

Therefore, the formula for the nth term of the given sequence is a_n = 9n - 26.

how many consecutive odd integers are there, or else I can't help you

==================================================

Work Shown:

x = some integer

2x = even integer

2x+1 = odd integer

(2x+1)+2 = 2x+3 = odd integer just after 2x+1

The integers 2x+1 and 2x+3 add to 36

(2x+1)+(2x+3) = 36

2x+2x+1+3 = 36

4x+4 = 36

4x+4-4 = 36-4 ... subtract 4 from both sides

4x = 32

4x/4 = 32/4 .... divide both sides by 4

x = 8

With x = 8, we can say

2x+1 = 2*8+1 = 17 is the first odd integer

2x+3 = 2*8+3 = 19 is the next odd integer

17+19 = 36, so the answer is confirmed

--------------------

A non-algebraic way to get the answer is to divide 36 in half to get 18

Then try odd integers around 18, so 19+21 = 40 but thats too high

then maybe try 15+17 = 32, thats too low

17+19 = 36 is right on the money

Answer:

10 weeks

Step-by-step explanation:

Answer: 26 weeks

Step-by-step explanation:

This is an example of an arithmetic sequence.

The first term = 3.5

common difference = 0.5

Using the formula for calculating the nth term of an arithmetic sequence :

[tex]t_{n}[/tex] = a + (n - 1 ) d

Therefore :

16.5 = 3.5 + ( n - 1 ) x 0.5

16. 5 = 3.5 + 0.5n - 0.5

16.5 = 3 + 0.5n

16.5 - 3 = 0.5n

13.5 = 0.5n

n = 13.5/0.5

n = 27

Therefore , it will take the cat (n-1)  weeks to weigh 16.5 ounce, which will be 27 - 1 = 26

check:

3.5 + 26 ( 0.5)

= 3.5 + 13

= 16.5

Answer:

Step-by-step explanation:

1/12 mile * 5280 feet/mile = 440 feet per train

50 miles/hour * 1/3600 hr/sec * 5280 ft/mile = 73 1/3 ft/second

one train has to travel 440 feet to pass the other train

440 feet * 1/(73 1/3) sec/ft = 6 seconds

The time it will take for the two trains to pass each other's rear car is 6 seconds.

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]

Two passenger trains travelling in opposite directions meet and pass each other. Each train is 1/12 miles long and is traveling 50 mph.

Therefore, the total distance that the two train needs to cover is twice the size of a train.

Distance = 2 × 1/12miles = 1/6 miles

Also, the relative speed of the two trains moving in opposite directions is,

Speed = 50 mph + 50 mph = 100 mph

Now, the time that the two trains need to cover the entire distance is,

Time = (1/6 miles)/ 100mph = 1/600 hours

Converting the time to seconds,

Time = 1/600 hours × 3600 = 6 seconds

she drinks 9/2 ounces of water in 1 hour

Step-by-step explanation:

On average, the person drinks 1/2 of a 6-ounce glass of water in 2/3 hour.

First of all, we have to rewrite the amount of water in a single fraction: we have

[tex]\frac{1}{2}\cdot 6 = \frac{6}{2}=3[/tex]

This means that the person drinks 3 ounces of water every 2/3 hours.

In order to find how much water she drinks in one hour, we use the following proportion:
