Step-by-step explanation:
Do mechanical waves travel faster or slower in more dense media?
When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same

Answer:
...
Step-by-step explanation:
1. B
angle A is 63 since 27+90= 117, 180-117= 63 (since a straight line is 180°)
2. 7x + 10 = 150 (since they are vertical angles)
7x = 140
x = 20
now plug in 7(20) +10
140+10=150

Step-by-step explanation:
(3x - 8) (4x + 2)
= 3x (4x + 2) - 8 (4x + 2)
= 12x² + 6x - 32x - 16
= 12x² - 26x - 16

Answer:
∠P ≅ ∠R
Step-by-step explanation:
We can see here two triangles , ∆ PQS and ∆ RQS.
To Prove :-
∠P ≅ ∠RWe can prove the given two triangles congruent then we can easily prove it out.
In ∆ PQS and ∆ RQS
PQ = QR ( given )QS = QS ( common)∠PQS = ∠ RQS .Therefore by SAS congruence condition , both triangles are congruent .
Hence ,
∠P ≅ ∠R ( by corresponding parts of congruent ∆s) Hence Proved !Help I need to get this right!!!

What is the probability of rolling a pair of dice and not rolling the same number?
Answer:
5/6
Step-by-step explanation:
The "first" dice can land on any number, so there are 6 choices. The "second" can not be the same number as the first one. So there are 5 choices. We multiply to get 6*5=30 ways to roll a different number. There are 6*6 total ways so the probability is 30/36 which simplifies to 5/6.

Answer:
x=2, y = -4.
or as an ordered pair it is (2, -4).
Step-by-step explanation:
-x + 6y = -26
x + 5y = -18 Add these 2 equations to eliminate x:
0 + 11y = -44
y = -44/11 = -4.
Now substitute y = -4 in the first equation:
-x + 6(-4) = -26
-x - 24 = -26
-x = -26 + 24 = -2
x = 2.
Check the result by substituting in equation 2:
x + 5y = 2 + 5(-4) = 2 - 20 = -18 - checks out.
Write the number using scientific notation:
23,000
The scientific notation representation of 23,000 is 2.3 x 10⁴
To express the number 23,000 in scientific notation, we need to move the decimal point to create a number between 1 and 10, and then multiply it by a power of 10.
Starting with 23,000, we can move the decimal point to the left four places to get 2.3. This means we divided the original number by 10,000 (10⁴). To compensate for this division, we multiply 2.3 by 10,000 in the form of 10⁴.
Thus, the scientific notation representation of 23,000 is 2.3 x 10⁴. The coefficient (2.3) is between 1 and 10, and the exponent (4) indicates the number of decimal places the original number was moved.

The dot plots below show the test scores of some mathematics students and some science students: Two dot plots are shown one below the other. The top and the bottom plots have the title Mathematics Students and Science Students respectively. Below the line for each dot plot is written Mark. The markings on each line are from 30 to 50 at intervals of 1. For the top plot there are two dots each for 34 and 40 and 1 dot each for 32, 33, 35, 37, and 39. For the bottom plot there are 2 dots each for 43, 46 and 49 and 1 dot each for 41, 42, and 47. Based on visual inspection of the dot plots, which group of students appears to have the larger average score? The mathematics students The science students Both groups are similar. Not enough information is available to draw a conclusion.
Answer:
I believe the Science Students have a higher average grade on their respective tests.
Step-by-step explanation:
The mathematics students all scored between 30-40 on their test while the science students scored between 40-50%. This shows that the science students had a larger average score. Hope this helps! Have a great day :)

6. Which expression is equivalent to 2(35 – 4) – (89 + 3)?
A. -2g - 1
B. -2g - 5
C. -2g - 7
D. -2g - 11
Answer:
Step-by-step explanation:
Following order of operations rules srequires that we do any work inside parentheses first. Thus, (35 - 4) = (31), and (89 + 3) = (92). Then:
2(35 – 4) – (89 + 3) = 2(31) - (92) = -60
