student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 34 centimeters, and the length of the other leg is 26 centimeters. The student incorrectly says that the length of the hypotenuse is 7.7 centimeters. Answer parts a and b.
a. Find the length of the hypotenuse of the right triangle to the nearest tenth of a centimeter.
Answers
Answer = 42.8
Step-by-step explanation:
All right triangles have one right (90-degree) angle, and the hypotenuse is the side that is opposite or the right angle, or the longest side of the right triangle.[1] The hypotenuse is the longest side of the triangle, and it’s also very easy to find using a couple of different methods. This article will teach you how to find the length of the hypotenuse using the Pythagorean theorem when you know the length of the other two sides of the triangle. It will then teach you to recognize the hypotenuse of some special right triangles that often appear on tests. It will finally teach you to find the length of the hypotenuse using the Law of Sines when you only know the length of one side and the measure of one additional angle

It takes 10 mins to fill a bath with just the hot tap and 15 minutes to fill it just with the cold tap.
How long wikll it take to fill the bath if you run both taps at once?
Please give a equation or the steps of solving, thanks a lot!
Answers
===========================================================
Explanation:
Let's say the tub is 30 gallons. I'm picking this number because it's the LCM of 10 and 15. Picking the LCM means that later division operations result in a whole number.
The hot tap takes 10 minutes to fill the tub. Its rate is 30/10 = 3 gallons per minute.
Rate = (amount done)/(time)
The cold tap works at a rate of 30/15 = 2 gallons per minute.
When both taps are running at the same time, they combine to a total rate of 3+2 = 5 gallons per minute. Therefore, it will take 30/5 = 6 minutes if both taps are opened.
Time = (amount done)/(rate)
-------------------------
Another approach:
The hot water tap takes 10 minutes to do 1 job. That "1 job" refers to "fill the bathtub". The unit rate here is 1/10 of a job per minute.
Meanwhile, the cold tap has a unit rate of 1/15 of a job per minute.
The combined rate is 1/10 + 1/15 = 3/30+2/30 = 5/30 = 1/6 of a job per minute.
x = number of minutes it takes to fill the bathtub if both taps are going at once.
We can say:
(unit rate)*(time) = amount done
(1/6 of a job per min)*(x minutes) = 1 job
(1/6)x = 1
x = 6 minutes is the final answer
-------------------------
Another approach:
The template for problems like this is:
1/A + 1/B = 1/C
where
A = amount of time for the hot tap water (working alone)B = amount of time for the cold tap water (working alone)C = amount of time if the two taps work togetherWe end up with the equation
1/10 + 1/15 = 1/x
This can be rearranged into
(1/10+1/15)x = 1
and also rearrange into
(1/6)x = 1
Follow the steps mentioned earlier to end up with 6 minutes as the final answer

Answer:
The answer is B. 54 degrees.
Step-by-step explanation:
A triangle must be 180 degrees when all three angles are added together. 180 minus 72 is 108 degrees, which you have to divide by two, because there are two y values.
You can check this by adding 72 plus 54 plus 54 to get 180 degrees total.

B) 6
C) 2
D) 4
Answers
Answer: the number is 3.
Step-by-step explanation:
(x × 10) + 6 = 36
[(3) × 10] + 6 = 36
Answer:
3
Step-by-step explanation
First let's create an equation
Let x = number
Product is outcome of multiplication
The product of 10 and a number can be written as 10x
Were supposed to add 6 to the product and that should equal 36
So the equation is 10x + 6 = 36
We now solve for x using basic algebra
10x + 6 = 36
Subtract 6 from both sides
10x = 30
Divide both sides by 10
X = 3

Explain how to show a reflected object is congruent to its preimage. Be specific.
Answers
Answer:
To show that a reflected object is congruent to its preimage, follow these steps:
Identify the line of reflection.
Locate corresponding points on the preimage and its reflection.
Measure the distances between the line of reflection and the corresponding points.
Compare the distances for each corresponding point.
If the distances are equal, the reflected object is congruent to the preimage.
Step-by-step explanation:
Step-by-step explanation:
To show that a reflected object is congruent to its preimage, you need to demonstrate that the reflected object and the preimage have the same size and shape. Here's how you can do it:
1. Identify the preimage
2. Determine the line of reflection
3. Reflect the preimage
4. Compare corresponding points
5. Check angles
6. Verify sides
7. State the conclusion
By following these steps and ensuring that all corresponding points, angles, and sides are congruent, you provide a specific and comprehensive demonstration that the reflected object is congruent to its preimage.
The figure shows two parallel lines AB and DE cut by the transversals AE and BD:

Triangle ABC is similar to triangle EDC , because m∠3 = m∠6 and m∠1 = m∠4
Triangle ABC is similar to triangle EDC , because m∠3 = m∠4 and m∠1 = m∠5
Triangle ABC is congruent to triangle EDC , because m∠3 = m∠4 and m∠1 = m∠5
Triangle ABC is congruent to triangle EDC, because m∠3 = m∠6 and m∠61 = m∠4
Answers
Answer:
Triangle ABC is similar to triangle EDC , because m∠2 = m∠6 and m∠1 = m∠5
Step-by-step explanation:
Nothing indicates any triangle sides are congruent, a necessary condition for the triangles to be congruent.
In triangles ABC and EDC, angles 1 and 5 are corresponding. They are "alternate interior angles" with respect to the transversal AE, so are congruent. Angles 2 and 6 are congruent for a similar reason. The vertical angles at C are congruent, so the triangles are similar.
Triangle ABC is similar to triangle EDC , because m∠2 = m∠6 and m∠1 = m∠5.

Find the 8th term in the sequence

Answers
Answer:
-64
Step-by-step explanation:
geometric
equation
a1(r)^n-1
-1/2(2)^8
Given sequence is -1/2, -1, -2, -4,...
We get,
a1 = -1/2
r = 2
n = 8
So,
a8 = a.r^(n-1)
a8 = -1/2 * 2^(8-1)
a8 = -1/2 * 2^7
a8 = -1/2 * 128
a8 = -64
Therefore, 8th term of the sequence is -64
