Answer:

Frequency of wave = 3 Hertz

Step-by-step explanation:

Given that:

Wavelength of wave = 20 meters

Velocity of wave = 60m/s

We know that:

v = fλ

Here,

v = velocity , f = frequency and λ = wavelength

Putting values in formula

60 = f(20)

20f = 60

Dividing both sides by 20

[tex]\frac{20f}{20}=\frac{60}{20}[/tex]

f = 3 Hertz

Hence,

Frequency of wave = 3 Hertz

Answer:

To convert a decimal to percent, just multiply it by 100, or move the decimal place 2 times

Ex: 0.29 x 100 = 29

The answer would be 29%

To convert a percent to a decimal, do the opposite

Ex: 29%/100 = 0.29

To convert decimals to percents is to multiply by 100 then add a percent sign. To convert percents to decimals is to move the decimal point two places to the left or divide by 100 and remove the percent sign.

Step-by-step explanation:

Example:2.5%

2.5% can be expressed in decimal form as 0.025. Since a percent represents the part per 100 to convert a percent to a decimal divide 2.5 by 100.

2.5/100=0.025.

Example:2.5

2.5 can be expressed in percent form as 250%.Since a decimal represents a fraction and a percent is out of 100, to convert a decimal to a precent multiply 2.5 by 100.

2.5 x 100=250

Add the percent sign

250%

Answer:

b = 4y

y = 1/4 * b

Step-by-step explanation:

Number of Blue fish = 16

Number of yellow fish = 4

Let:

Blue fish = b

Yellow fish = y

b = 4y

b = 4(4)

b = 16

From ;

b =4y

y = b/4

y = 1/4 * b

Hence,

y = 1/4 * 16

y = 16/4

y = 4

Answer: (3, -2)

Answer:

$69.51

Step-by-step explanation:

To solve the discount problem we have to multiply the price by the new percent (trust me it will make sense later)

To find the new percent after the 30% discount we have to subtract 30% from 100% which will leave us with 70% or 0.70

Now we multiply:

$99.30 x 0.70 = 69.51

So the new price after the discount is $69.51

Answer:

The star equals 96

Step-by-step explanation:

The star will be equal to 5x-14 because they are vertically opposite.

The two exterior angles are supplementary.  Set up the equation

5x - 14 + 3x + 18 = 180        Combine the terms on the left.

8x + 4 = 180                        Subtract 4 from both sides

8x = 180 - 4                         Combine

8x = 176                               Divide by 8

x = 176 / 8

x = 22

===================

5x - 14

5*22 - 14

Answer: The probability that Jo is not late on Monday = 0.6

Step-by-step explanation:

The probability of getting late is independent on each day.

Also, for an event E

Probability of not E = 1- P(E) , where P(E) = Probability of happing E

Given: The probability Jo is late on a Monday is 0.4.

Then, the probability that Jo is not late on Monday =  1-0.4= 0.6

Hence, the probability that Jo is not late on Monday = 0.6

Answer:

-0.4

Step-by-step explanation:

its that one

The strongest correlation is -0.4.

Option C is correct.

Correlation is a statistical term that expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical tool for describing simple relationships without stating a cause and effect link.

When the result is closer to +1 (positive correlation) or -1 (negative correlation), the strongest correlation is considered (negative correlation).

A positive correlation coefficient means that the value of one variable is directly related to the value of another.

Here -0.4 is the closest value to 1.

So, the strongest correlation is -0.4.

Step-by-step explanation:

let 'x' = each congruent side

let '2x - 7' = side of base

x + 2x - 7 = 63

3x = 70

x = 17.5

Answer:

Your answer is 31.4°.

Step-by-step explanation:

The answer itself just requires very simple thinking. Complementary angles are any two angles that add up to 90 degrees. We are given ANGLE<1, so all we have to do is subtract 90 from 58.6 to find ANGLE<2.

90°-58.6°= 31.4°

Answer:

y = -x + 1

Step-by-step explanation:

We're putting it into the form y=mx+b where m is the slope, and b is the y-intercept.

When two lines are parallel, they have the same slope, so the slope is going to be -1.

New equation: y = -x + b.

Now, you know that (4, -3) is a solution so you can plug in x = 4 and y = -3, then see what value of b make the equation true.

-3 = -4 + b

add 4 to both sides

1 = b

This means that the equation is y = -x + 1
