In the figure, line m is parallel to line n. The measure of angle 2 is 40 degrees and the measure of angle 3 is 68 degrees. What is the measure of angle 5? Explain how you found the answer using the relationships of angles.

Answer:

Section A: Sally drives from her house to her friend's house.

Section B: Sally stops to visit her friend.

Section C: Sally drives from her friend's house to the post office to drop off a card.

Section D: Sally drives back to her house.

Step-by-step explanation:

As you can see in the graph, the point (0,0) is the location of Sally's house. In that point the distance is 0 and the time is 0.

In Section A she drives 3 miles in 6 minutes from her house to her friend's house.

In Section B, the distance does not change, this means that Sally stopped at her friend's house for 4 minutes.

In Section C she drives (for 4 minutes) 1 mile from her friend's house to some place (In this case the post office).

In Section D she comes back to 0 distance, then, she drives back to home.

Step-by-step explanation:

2/10 have a common term of 2.  reduce both the numerator and denominator by dividing both by 2.

2/2 = 1  

10/2 = 5

the reduced fraction woudl be 1/5

Answer:

No 2/10 is not the same as 4/5

Step-by-step explanation:

The reason why is because If you doubled 2/10 then it would be 4/20 not 4/5 and if you divided by 4/5 by 2 then it would be a complex fraction of 2/1/2 that is why the statement 4/5 is equal to 2/10 is false.

Answer:

[tex]40 +20 = 72 -12\\\\60 = 60[/tex]

Step-by-step explanation:

If we have an expression in the following way:

[tex]c(a + b)[/tex]

So the distributive property says that:

[tex]c(a + b) = ca + cb[/tex]

In this case we have the expression:

[tex]4(10 + 5) = 6(12-2)[/tex]

Therefore we can rewrite it as:

[tex]4 * 10 + 4 * 5 = 6 * 12 -2 * 6[/tex]

Then we have left:

[tex]40 +20 = 72 -12\\\\60 = 60[/tex]

4*10+4*5=6*12-6*2

40+20=72-12

60=60

Answer: 60=60

I think it’s b I’m currently learning the same thing in my class

Answer:

The answer is A. 2.0

Step-by-step explanation:

One of the angles is a right angle, because x is the tangent of that circle. The other radius is 1.5, since all radius are equal to each other. Then you use the Pythagorean theorem (a²+b²=c²). C is always the hypotenuse. The hypotenuse in this triangle is the 1.5 + 1 line. A and b can be changed within each other. I put A = 1.5, B = x, and C = 2.5. My equation was 1.5²+x²=2.5². Remember the formula can also be x²+1.5²=2.5² as well. Then you solve the equation you just made. You multiply everything by each other, because of the ² (I forgot the name of it, hehehe). You will get 2.25+x²=6.25. Then you subtract 2.25 to both side. x²= 4. Then you square root both sides to make x by itself. x=2. That's how you get 2 as your answer

Based on the calculations below, the slope of this graph is equal to: C. 2/3.

In Mathematics and Euclidean Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

[tex]Slope(m)=\frac{y_2-y_1}{x_2-x_1}[/tex]

By substituting the given data points (0, -2), and (3, 0) into the formula for the slope of a line, we have the following;

Slope of graph = (0 - (-2))/(3 - 0)

Slope of graph = (0 + 2)/(3 - 0)

Slope of graph = 2/3

Based on the graph, the slope is the change in y-axis with respect to the x-axis, and it is equal to 2/3.

I think the answer is most likely 80

The correct answer is C. The graph of the function [tex]y = (1/3)^x[/tex] decreases from left to right, exhibiting exponential decay as x increases.

To complete the table for the function [tex]y = (1/3)^x[/tex], we need to substitute the given values of x into the equation and calculate the corresponding values of y.

Let's start by substituting -3 into the equation:

y = (1/3)^(-3)

y = 1/(1/3)^3

y = 1/1/27

y = 27

Next, let's substitute -1 into the equation:

y = (1/3)^(-1)

y = 1/(1/3)^1

y = 1/(1/3)

y = 3

Then, let's substitute 0 into the equation:

y = (1/3)^0

y = 1

After that, let's substitute 1 into the equation:

y = (1/3)^1

y = 1/3

Lastly, let's substitute 2 into the equation:

y = (1/3)^2

y = 1/9

Therefore, the completed table is as follows:

x | -3 | -1 | 0 | 1 | 2 | 3

y | 27 | 3 | 1 | 1/3 | 1/9 | 1/27

To graph the function y = (1/3)^x, we plot the points from the completed table on a graph. The graph of this function is an exponential decay curve that starts at (0, 1) and decreases as x increases. The curve is steeper for larger x values and approaches the x-axis as x approaches infinity.

In terms of the given options, the correct answer would be C. The graph of the function decreases from left to right.

Answer would be D which is L

Answer:

L

Step-by-step explanation:

Most people prefer to use a unit of measurement that gives a number they can easily visualize, usually between 0.1 and 1000.

You wouldn't use centimetres, because that is a unit of length, and grams are a unit of mass.

The amount of milk in a half-gallon carton is about 2 L or 2000 mL, so you would measure the milk in litres (L).

Answer:

C

Step-by-step explanation:

given

x² = 64 ( take the square root of both sides )

x = ± [tex]\sqrt{64}[/tex] = ± 8

Tamara omitted the negative square root → C

Tamara made the mistake of only finding the positive square root, not the negative square root.

The mistake that Tamara made in finding the solution to the equation x^2=64 is that she only found the positive square root, not the negative square root.

When solving a quadratic equation like this, you need to consider both the positive and negative square roots, because both values satisfy the equation. So the correct solution to x^2=64 is x=8 and x=-8.

Answer:

In parallelogram ABCD

FD is perpendicular to BC

BE is perpendicular to CD

Consider triangle BEC and triangle DFC

FC = EC (Given)

Angle BEC = Angle DFC (=90°)

Angle BCE = Angle DCF (common)

Therefore triangle BEC is congruent to triangle DFC (AAS congruency)

DF = BE (CPCT)

Since the altitudes are equal their bases will also be equal

Therefore BC = DC

Therefore BC = DC = AD = AB

Therefore ABCD is a rhombus

Hope this helps!

Mark me as brainliest

Since [tex]\(ABCD\)[/tex] is a parallelogram with all four sides congruent, [tex]\(ABCD\)[/tex] is a rhombus. Hence, [tex]\(ABCD\)[/tex] is proven to be a rhombus.

To prove that parallelogram [tex]\(ABCD\)[/tex] is a rhombus, we need to show that all sides are congruent.

Given:

1. [tex]\(ABCD\)[/tex] is a parallelogram.

2. [tex]\(BE \perp CED\).[/tex]

3. [tex]\(DF \perp BFC\).[/tex]

4. [tex]\(CE \cong CF\).[/tex]

Proof:

1. Parallelogram Properties:

  - In a parallelogram, opposite sides are congruent and parallel.

  - Therefore, [tex]\(AB \parallel CD\)[/tex] and [tex]\(AD \parallel BC\)[/tex].

  - Also, [tex]\(AB \cong CD\)[/tex] and [tex]\(AD \cong BC\)[/tex].

2. Congruent Segments:

  - [tex]\(CE \cong CF\) (given).[/tex]

  - Since [tex]\(BE \perp CED\)[/tex] and [tex]\(DF \perp BFC\)[/tex], [tex]\(BE\)[/tex] and [tex]\(DF\)[/tex] are heights from [tex]\(B\)[/tex] and [tex]\(D\)[/tex] respectively to line [tex]\(CED\)[/tex].

3. Triangle Congruence:

  - Consider [tex]\(\triangle CEF\)[/tex]. Since [tex]\(CE \cong CF\)[/tex] and [tex]\(BE \perp CED\)[/tex], [tex]\(DF \perp BFC\)[/tex], [tex]\(\triangle CEF\)[/tex] is isosceles with base [tex]\(EF\)[/tex].

4. Diagonals in Parallelogram:

  - Diagonals of a parallelogram bisect each other.

  - Since [tex]\(\triangle CEF\)[/tex] is isosceles and [tex]\(CE = CF\)[/tex], the diagonals [tex]\(BE\)[/tex] and [tex]\(DF\)[/tex] bisect each other at [tex]\(E\)[/tex] and [tex]\(F\)[/tex].

5. Symmetry and Congruence:

  - Since diagonals bisect each other and the height from [tex]\(B\)[/tex] and [tex]\(D\)[/tex] are equal, segments from [tex]\(B\)[/tex] and [tex]\(D\)[/tex] to the diagonals are congruent.

6. Sides of Parallelogram:

  - From symmetry and congruence, all sides of the parallelogram are equal.

  - Therefore, [tex]\(AB \cong BC \cong CD \cong DA\)[/tex].

Conclusion:

Since [tex]\(ABCD\)[/tex] is a parallelogram with all four sides congruent, [tex]\(ABCD\)[/tex] is a rhombus.

Hence, [tex]\(ABCD\)[/tex] is proven to be a rhombus.

Answer:

2

Step-by-step explanation:

Each time you flip a coin, there is a 50% change of it landing on tails.  So half the time you should get a tails.  

Half of 4 is 2, so you will likely get 2 tails.

Final answer:

When you flip a coin 4 times, the best prediction for the number of tails is 2, based on the equal 50-50 chance for heads or tails on each toss. However, you may actually get any number of tails from 0 to 4 due to randomness.

Explanation:

If you flip a coin 4 times, the best prediction for the number of times it will land on tails can be determined by understanding probability. Each coin flip represents an independent event with a 50-50 chance of landing on either heads or tails. Therefore, over a small number of flips, such as 4, it is expected that you will get tails approximately half the time. However, it is possible to see any combination of heads and tails.

When considering all the possible outcomes of flipping a coin 4 times:

4 heads, 0 tails (HHHH)

3 heads, 1 tail (HHHT, HHTH, HTHH, THHH)

2 heads, 2 tails (HHTT, HTHT, HTTH, THHT, THTH, TTHH)

1 head, 3 tails (HTTT, THTT, TTHT, TTTH)

0 heads, 4 tails (TTTT)

Given that each of these outcomes is equally likely, the prediction would be 2 tails because it is the average outcome. However, it is important to recognize that while 2 tails is the most likely single outcome, any number of tails between 0 and 4 is possible due to the randomness of each flip.
