A classmate said that ab is parallel to dc based on the diagram below. Explain your classmate's error.

Answers

For AB to be parallel to DC based on the diagram, angle AWZ must be equal to angle WZY.

But in the diagram shown, angle AWZ is equal to angle XYC and we are not told that WZ is parallel to XY.

Therefore his error is that he misapplied the alternate angle property.

Sherman hopes to get at least a 90 average on his science test. He has one more test before the end of the year. His past test scores are 79, 94, 91, and 92.Write and solve an inequality that represents the situation. What is the lowest score Sherman can get on his final test and reach his? show your work

Answers

(79 + 94 + 91 + 92 + x) / 5 > = 90
(356 + x) / 5 > = 90
356 + x > = 90 * 5
356 + x > = 450
x > = 450 - 356
x > = 94 <=== Sherman can get the lowest score at 94

Answer:

94 points

Step-by-step explanation:

The mean is defined by the sum of the numbers divided by how many numbers there are, so:

[tex]\frac{(79+94+91+92+x)}{5}>=90\\\\\frac{(356+x)}{5}>=90[/tex]

Multiplying both sides by 5

[tex](356+x)>=450[/tex]

Subtracting 356 on both sides:

[tex]x>=94[/tex]

So Sherman has to obtain at least 94 points on his final test in order to get an average of at least 90.

On a adventure trail, you biked 12 mi, walked 4 mi, ran 6 mi, and swam 2 mi. What fraction of the total distance did you bike? Write this number as a decimal.

Answers

First you want to add all of those together.
12 + 4 + 6 + 2 = 24
So there are 24 miles in total.
Next, it says she biked 12 miles so you make a fraction.
12 / 24 which can be reduced to 1/2.
She spent one half of the total distance biking.
Hope this helps!

You biked 1/2, or 0.5, of the total distance on the adventure trail. The total distance covered was 24 miles.

To calculate the fraction of the total distance that you biked, we first need to determine the total distance covered in the adventure trail.

Biking: 12 milesWalking: 4 milesRunning: 6 milesSwimming: 2 miles

Adding these distances together gives us a total distance of:

Total Distance = 12 + 4 + 6 + 2 = 24 miles

The fraction of the distance biked is then given by the biking distance over the total distance:

Fraction Biked = 12 miles / 24 miles = 1/2

To express this fraction as a decimal, we perform the division:

Decimal Form = 1 ÷ 2 = 0.5

Therefore, you biked 1/2 (or 0.5) of the total distance.

<5 and <6 are vertical angles and m<5=33° find m<6

Answers

Answer:  m∡6 = 33°.
________________________________________________
Since all vertical angles are congruent and have EQUAL measurements, 

and ∡5 and ∡6 are vertical angles; 

then, m∡5 = m∡6 .
________________________________________________
So;  given m∡5 = 33° ;  m∡6 = 33° .
________________________________________________

The measure of the angle 6 is 33°.

Given that, ∠5 and ∠6 are vertical angles and m∠5=33°.

What are vertical angles?

Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.

As we know, the vertical angles are congruent.

So, ∠5 = ∠6

⇒ ∠6 = 33°

Therefore, the measure of the angle 6 is 33°.

If you are using continuous compound interest, the formula is A = Pe^RT where A= amount, P= principal value, R = the rate, and t = time. E is an actual number that is kinda hard to explain but it's just a button on the calculator. 

In this case the equation would be A = 350e^(0.03)(10). This gives you approximately 472.4506 or approximately $472.45 since it's money and you round to the nearest penny. 
the answer is $472.45

How to find volume of a right circular cone?

And let its height be 'h' units.

Then, its volume is given as:

Since Right circular cone is the cone in which the line joining peak of the cone to the center of the base of the circle is perpendicular to the surface of base.

Here, Laura has found the volume of a cylinder. which means, she will need to subtract volume from this shape in order to reveal a cone.

Harry has 3 bamboo poles of different lengths. The total combined length of the three poles when placed end to end is 47 1/2 inches long. Pole B is 1 3/4 times as long as pole A and pole C is 2 1/2 inches longer than pole A. Find the length of Pole C

Answers

Final answer:

To find the length of pole C, we can set up a system of equations using the given information. Solving the system of equations will give us the values of the lengths of poles A, B, and C. The length of pole C is found to be 14.5 inches.

Explanation:

We can solve this problem by setting up a system of equations. Let's represent the length of pole A as 'a', the length of pole B as 'b', and the length of pole C as 'c'. We are given that pole B is 1 3/4 times as long as pole A, so we can write the equation b = 1.75a. We are also given that pole C is 2 1/2 inches longer than pole A, so we can write the equation c = a + 2.5.



Since the total combined length of the three poles is 47 1/2 inches long, we can write the equation a + b + c = 47.5. Now we have a system of three equations:



b = 1.75ac = a + 2.5a + b + c = 47.5



We can solve this system of equations to find the length of pole C. Substituting equation 1 and equation 2 into equation 3, we get:



a + 1.75a + (a + 2.5) = 47.5



Combining like terms, we get:



3.75a + 2.5 = 47.5



Subtracting 2.5 from both sides, we get:



3.75a = 45



Dividing both sides by 3.75, we get:



a = 12



Now that we know the length of pole A, we can substitute it into equation 1 to find the length of pole B:



b = 1.75 * 12 = 21



Finally, we can substitute the length of pole A and pole B into equation 2 to find the length of pole C:



c = 12 + 2.5 = 14.5



Therefore, the length of pole C is 14.5 inches.

A=-0.4,B=-0.7,C=-5/16,D=9/16

A=9/16,B=-5/16,C=-0.4,D=-0.7

A=-0.7,B=-9/16,C=-0.4,D=-5/16

Answers

Because none of the points on the number line are above 0, we know that the points will be negative.
This eliminates the second and third choices, as they contain positive numbers.
The first point, A, is a number less than -0.5 or -1/2
The first choice matches A with -5/16, which is less than -0.5 or -1/2
Therefore, the fourth choice must be the correct answer.
