It takes the sound of a bat's cry 1/165 seconds to reach its prey and echo back

The given parameters are

Speed = 330 meters per second

Distance = 1 meters

The time taken to get to the prey is calculated as

Speed =Distance/Time

Substitute the known values in the above equation

So, we have

330 = 1/Time

Cross multiply the factors of the equation

So, we have

Time * 330 = 1

Divide both sides of the equation by 330

So, we have

Time 1 = 1/330

Similarly, the time taken to get from the prey is calculated as

Speed =Distance/Time

Substitute the known values in the above equation

So, we have

330 = 1/Time

Cross multiply the factors of the equation

So, we have

Time * 330 = 1

Divide both sides of the equation by 330

So, we have

Time 2 = 1/330

The time it takes a bat's cry to reach its prey and echo back is

Time = Time 1 + Time 2

So, we have

Time = 1/330 + 1/330

Evaluate the sum

So, we have

Time = 2/330

Simplify the quotient

So, we have

Time = 1/165

Hence, it takes the sound of a bat's cry 1/165 seconds to reach its prey and echo back

Answer:

kids= 15

adults= 21

Step-by-step explanation:

Step one

let the number of kids be x

and  adults be y

Kids tickets are two dollars and adult tickets are five dollars

The carnival sold 36 tickets to this game and collected $135

so the system of the equation is

2x+5y=135----------1

x+y=36---------------2

from 2 x= 36-y

put x= 36-y in 1

2( 36-y)+5y=135

72-2y+5y=135

collect like terms

3y=135-72

3y=63

divide both sides by 3

y= 63/3

y=21

put y= 21 in 2

x+21= 36

x=36-21

x=15

Given that,

An oil company fills 1 over 10 of a tank in 1 over 5 hour.

To find,

How long it will take for the tank to fill completely.

Solution,

Let it takes t time to fill the tank completely. It can be calculated as follows :

[tex]t=\dfrac{\dfrac{1}{10}}{\dfrac{1}{5}}\ \text{hours}\\\\=\dfrac{1}{10}\times 5\ \text{hours}[/tex]

Hence, the rate is "1 over 10 • 5 hours ". The correct option is (b).

Answer:

The length of x is 4

Step-by-step explanation:

The scale factor is Large/small where 10/8 which is DF/AC.

THE SCALE factor is 5/4.

To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.

5/4 = DE/AB

5/4 = 5/X

X = 4

To find Y in EF will use the corresponding BC which is 6.

5/4 = EF/BC

5/4 = Y/6

Y= 7.5

info: use CORRESPONDING ABC AND DEF .

Answer:

see explanation

Step-by-step explanation:

If y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation and

k = [tex]\frac{y}{x}[/tex]

Check this ratio for each ordered pair, that is

k = [tex]\frac{14}{7}[/tex] = [tex]\frac{42}{21}[/tex] = [tex]\frac{126}{63}[/tex] = [tex]\frac{378}{189}[/tex] = 2

Thus k = 2 and

y = 2x ← equation of variation

Answer:

1 /12

Step-by-step explanation:

Given that:

Number of sports game = 5

Role playing games = 3

Action games = 8

Total = (5 + 3 + 8) = 16

The probability of selecting two sports game from the bag :

First selection = sport game and second selection will also be a sport game.

This scenario with be a selection without replacement pattern

First selection :

Number of sports game / total number of options

5 / 16

SEcond selection : total left = 16 - 1 = 15 ; number of sports game = 5 - 1 = 4

Hence

P(sports on second selection) = 4 / 15

P(sports on first and second) :

5/ 16 * 4/15 = 20/ 240 = 1 / 12

The correct method to proceed for simplification of the expression →

- (x + 3) – 2(4x – 3)  are -

Step 1 : –x – 3 – 8x + 6

Step 2 : -9x +3

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is the following expression -

-(x + 3) – 2(4x – 3)

The given expression is -

-(x + 3) – 2(4x – 3)

The correct method to proceed for simplification is as follows -

- x - 3 - 8x + 6

- x - 8x - 3 + 6

-9x + 3

Therefore, the correct method to proceed for simplification of the expression → - (x + 3) – 2(4x – 3) are -

Step 1 : –x – 3 – 8x + 6

Step 2 : -9x +3

(-2,3)    k=-1/2

Find the equation of the line:

[tex]y=kx+b[/tex]

[tex]\displaystyle\\3=-\frac{1}{2}*(-2)+b\\\\3=1+b\\ 3-1=1+b-1\\2=b\\Thus,\\y=-\frac{1}{2} x+2[/tex]

The required 3 more coordinates are (0, 2), (1, 3/2), and (2, 1).

Given that,
To determine points using a slope of -1/2 and the point (-2,3).

Coordinate, is represented as the points on the x-axis and y-axis of the graph.

Here,

using the slope-intercept form of the equation,
y = mx + c
we have a point (-2, 3) and m = -1/2
Put point and slope in the equation,
3 = -1/2 * -2 + c
c = 3 - 1
c = 2
Now equation would be
y = -1/2x + 2
Now,
For x = 0
y = 2

Coordinate will be (0,2)

For x = 1
y = -1/2 + 2
y =  3/2
Coordinate will be (1, 3/2)

For x = 2
y = -1/2 * 2 + 2
y = 1
Coordinate will be (2, 1)

Thus, the required 3 more coordinates are (0, 2), (1, 3/2), and (2, 1).
