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: 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:

2.06 rad

Step-by-step explanation:

To change degree measure to radian measure

radians = degrees × [tex]\frac{\pi }{180}[/tex] , then

radians = 118 × [tex]\frac{\pi }{180}[/tex]

            = [tex]\frac{118(\pi )}{180}[/tex] ≈ 2.06 rad ( to the nearest hundredth )

Answer:

2.06 radians to nearest hundredth.

Step-by-step explanation:

Radians = degrees * π/180

= 118 * π/180

= 0.6556π

= 2.0596.

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

Have you by any chance mixed "g" with "9?"  Double check this and submit this question again, please.

The equation should be rewritten by completing the square as x² + 18x + (18/2)² = 8 + (18/2)².

The solutions to the equation is x = -9 + √89 or x = -9 - √89.

In Mathematics and Geometry, the standard form of a quadratic equation is represented by the following equation;

ax² + bx + c = 0

Next, we would solve the given quadratic equation by using the completing the square method;

x² - 6 = 2 - 18x

x² + 18x = 8

In order to complete the square, we would have to add (half the coefficient of the x-term)² to both sides of the quadratic equation as follows:

x² + 18x + (18/2)² = 8 + (18/2)²

x² + 18x + 81 = 8 + 81

Part 2.

x² + 18x + 81 = 89

x² + 9x + 9x + 81 = 89

x(x + 9) + 9(x + 9) = 89

(x + 9)(x + 9) = 89

x = -9 + √89 or x = -9 - √89.

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:

285 students were in school.

Step-by-step explanation:

5%=0.05

0.05*300=15

300-15=285

There were 285 students in school.

Given that 5% of the 300 students were absent, we can calculate it as follows:

= 5% of 300

= (5/100) x 300

= 0.05 x 300

= 15

Therefore, there were 15 students absent from school.

Now, the In school students

Total students - Absent students = In-school students

300 - 15 = 285

So, there were 285 students in school.

Answer:

17.7

Step-by-step explanation:

I'm assuming you meant R(17, -2) to W(-2, 3).  Here the x-coordinate changes by 17 - (-2), or 19, and the y-coordinate by 5.  Think of these as the legs of a right triangle.  The distance between these points is the length of the hypotenuse of this triangle:  d = √(5^2 + 17^2)

or √314, which, to the nearest tenth is 17.7.

Answer:

x equals 50°.

Step-by-step explanation:

The sum of all angles of a triangle is 180°

So, to find the missing angle x, we can use the following equation:-

70° + 60° + x° = 180°

130° + x° = 180°

x° = 180° - 130°

x° = 50°

Answer:

Anita's monthly bill will be $164.25.

Step-by-step explanation:

Since Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS, and 25 cents per off-peak time SMS, if she sends 45 SMSs during peak time and 105 SMSs during off-peak time In a month To determine what will her monthly bill come to, the following calculation must be performed:

100 + (0.85 x 45) + (0.25 x 105) = X

100 + 38.25 + 26.25 = X

138.25 + 26.25 = X

164.25 = X

Therefore, her monthly bill will be $ 164.25.
