Answer:

because when you do 15*0 it =0 so anything else multiplied by 0 is 0

Step-by-step explanation:

Since the waves are 0.15 apart and made by tapping the water surface twice each second the speed of waves in the puddle is 0.6 m/s

To answer the question, we need to know what a wave is

A wave is a disturbance in space which carries energy from one point to another

The speed of a wave v = fλ where

Since the puddles are 0.15 m are and we know that this is the distance from crest to crest.

Also, the distance from crest to crest is λ/2

So, λ/2 = 0.15

λ = 2 × 0.15 m

= 0.3 m

Also, since the tapping by the water surface is done twice each second, the frequency, f = 2 times/s = 2 Hz

Substituting the values of the variables into the equation, for speed, we have

v = fλ

v =  2 Hz × 0.3 m

v = 0.6 m/s

So, the speed of waves in the puddle is 0.6 m/s

Answer:

The next two terms of the sequence -7, 14, and -28 are 56 and - 112.

Step-by-step explanation:

-7 * -2 = 14

14 * -2 = -28

The sequence is to multiply each number by -2.

-28 * -2 = 56

56 * -2 = -112

Answer: The next two terms of the sequence -7, 14, and -28 are 56 and - 112.

Slope is :-

[tex] \boxed{\bf \; m \; = - \cfrac{7}{5}} [/tex]

Step-by-step explanation:

Given two points :-

[tex] \sf \implies(-5,3) , (0,−4)[/tex]

To Find :-

The slope of Two points that is given.

Solution :-

[tex]\sf \implies(-5,3) , (0,−4)[/tex]

As we know that the formula of Slope is :-

[tex]\sf \implies \boxed{\sf Slope = \cfrac {y_2 - y_1}{x_2 - x_1}}[/tex]

Now, Put the values of x and y :-

Where,

[tex]{ \sf \: {y_2} = - 4}[/tex]

[tex] \sf \: x_2 = 0[/tex]

[tex] \sf \: y_1 = 3[/tex]

[tex] \sf \: x_1 = - 5[/tex]

Put the values on their respective place :-

[tex]\sf \implies \: Slope = \cfrac{ - 4 - 3}{0 - ( - 5)} [/tex]

Simplify this Fraction :-

Add -4 and -3 which is on the numerator as we know that "-" and "-" equals to "+":-

[tex]\sf \implies \: Slope = \cfrac{ - 7}{0 - ( - 5)} [/tex]

Now Add 0-(-5) on the denominator as we know that "-" and "-" equals to "+":-

[tex]\sf \implies \: Slope = \: \cfrac{ - 7}{ 5} [/tex]

Which can be rewritten as,

[tex]\sf \implies \: m = \: - \cfrac{7}{5} [/tex]

This fraction can't be cancelled. Hence, the slope of the two points is:-

[tex]\sf \implies \boxed{\sf m = \: - \cfrac{7}{5}} [/tex]

Note :- Slope can also be denoted as [tex] m [/tex].

The Number Line

A number line is defined as a graphic representation of numbers such as fractions, integers, and whole numbers laid out evenly on a straight horizontal line.

The number line can be used for comparing and ordering numbers and also performing simple operations such as addition and subtraction.

There are four numbers located on a number line. Let's analyze each one:

A: -27/3. This division is a whole number =.9 and is correctly placed.

B: -13/2 = -6.5. Note this value was incorrectly placed at -4.5.

C: 9/2= 4.5. The number is correctly placed

D: 21/3 = 7. This number is also placed in the correct location

Correct Choice: G. point B

Answer:

40.99 is 10 times more than 4.099

Step-by-step explanation:

Given the values :

4.099 and 40.99

4.099 is 110 of 40.99 : 110 * 40.99 = 4508.9 (false)

4.099 is 1100 of 40.99 : 1100 * 40.99 = 45089 (false)

40.99 is 10 times more than 4.099 : (10 * 4.099) = 40.99 (true)

40.99 is 100 times more than 4.099 : (100 * 4.099) = 409.9 ( false)

4.099 is 10 times more than 40.99 : (10 * 40.99) = 409.9 (false)

Answer:

There are 25 inches in the larger dimension.

Step-by-step explanation:

∵ 1 foot = 12 inches

∵ The small dimension after enlargement is 1 foot and 3 inches

→ Change it to inches only

∴ The small dimension = 1(12) + 3 = 12 + 3

∴ The small dimension = 15 inches after enlarged

∵ The small dimension of the photo before enlarged = 3 inches

→ Divide its length after enlarged by its length before enlarged to

   find the scale of the enlargement

∵ 15 ÷ 3 = 5

∴ The scale of enlarged is 5

→ To find the larger dimension after enlarged multiply its length

   before enlarged by 5

∵ The larger dimension before enlarged = 5 inches

∴ The larger dimension after enlarged = 5 × 5

∴ The larger dimension after enlarged = 25 inches

∴ There are 25 inches in the larger dimension.

Answer:

c = 3.5 - x

Step-by-step explanati

x^2 - 14x + c = (x - 7)^2

x^2 - 14x + c = x^2 - 7^2

x^2 - 14x + c - x^2 = x^2 - 49 - x^2

-14x + c = 49

-14x / -14 + c = 49 / -14

x + c = 3.5

x - x + c = 3.5 - x

c = 3.5 - x

Answer:

31 degrees

Step-by-step explanation:

149 + 149 = 298

360 - 298 = 62

62 / 2 =31

Answer:

61 degrees

Step-by-step explanation:

you know that there is a strait line which is equal to 180. So if you subtract 149 from 180 you get 31 which is the angle included with x. therefore you subtract your total number, which is 92 by 31 and you get 61 degrees

 m∠1 + m∠2 = m ∠4 , under the exterior angle property of a triangle which says that sum of the interior opposite angles of an exterior angle will be equal to the measure of the exterior angle .

To prove that m∠3 + m ∠1 +  m∠2 = 180° , let us use the angle sum property .

= Angle sum property = Sum of the three interior angles in a triangle will be equal to 180° .

= Since  ∠1 ,  ∠2 and  ∠3 are the interior angles of this triangle , their sum will be equal to 180° .

Hence proved that m∠1 +  m∠2 + m∠3 = 180°

∴ m∠1 +  m∠2 + m∠3 = 180° under the angle sum property of a triangle .

Answer:

$5,415.49

Step-by-step explanation:

Cost of the boat = $16,500

Decrease in value per year = 13%

Worth of the boat in 8 years = ?

Remaining value = 100% - 13%

= 87%

Worth of the boat in 8 years = cost of the boat × remaining value^8

= $16,500 × 87%^8

= $16,500 × 87/100^8

= $16,500 × 0.87^8

= $16,500 × 0.3282116715437121

= $5,415.49

The worth of the boat after 8 years = $5,415.49
