Two boys A and B are a two diametrically opposite points on a circle. at one instant the two start running on the circle​

Answers

Answer 1

Step-by-step explanation:

let the distance travel by both be a&b

a has a distance of d1 like wise b

speed=distanc/time

d1=2v

d2=4v

total distance

d1+d2=180

2v+4v=180

6v=180

v=30

d1=2*30

d1=60

d2=4*20

d2=120

now start u get u starting

not that there meet at same point so now calculate the time they will trave in there various direction

time=distance/velocity

but they but move at a standard velocity

Answer 2

Answer:

is this the full question:  Two boys A and B are at two diametrically opposite points on a circle. At one instant the two start running on the circle; A anticlockwise with constant speed v and B clockwise with constant speed 2v. In 2 minutes, they pass each other for the first time. How much later will they pass each other for the second time?

if yes than this is the answer:-

A speed = v

B speed = 2v

Time to meet = 2 minutes

d= pi r ( distance they have to run to meet)

they are running towards each other.

(2v+v)

speed = 3v

d=rt

pi*r = 3v*2

r= 6v/pi

circumference = 2* pi*r

=2*pi*(6v/pi)

=12v

...

Now distance to travel to meet = 12v

speed = 3v

t=d/r

t= 12v/3v

t= 4 minutes

I hope this helps a little bit.

Substitute t = 3 and t = 6 to determine if the two expressions are equivalent. 3 (2 t + 5) 6 t + 15 Which statements are true? Select the three correct answers. The value of both expressions when t = 3 is 33. The value of both expressions when t = 3 is 23. The value of both expressions when t = 6 is 41. The value of both expressions when t = 6 is 51. The two expressions are equivalent. The two expressions are not equivalent.

Answers

Answer:

If t= 6

3 (2 x 6 + 5) 6 x 6 + 15

3 (12+5) 36 + 15

3 x 17 =51

= 51

The value of both expressio

Step-by-step explanation:

The value of both expressions when t=6 is 51

When t = 3

3(2 x 3 + 5) 6 x 3 + 15

3 (6 +5) 18 + 15

3 x 11 =33

= 33

The value of both expressions when t= 3 is 33

Answer:

A. The value of both expressions when t=3 is 33

D. The value of both expressions when t = 6 is 51.

E. The two expressions are equivalent.

On a time crunch!!!!!

Answers

Answer: x = 0

Step-by-step explanation:

Subtract 6x^3+29x^2+47x+28 from both sides:

(2^2 + x + 4) (x - 7) - 6x^3+29x^2+47x+28

(6x^3+29x^2+47x+28)-6x^3+29x^2+47x+28

= -4x^3 - 14x^2 - 36x = 0

Now factor the left side:

-4x^3 - 14x^2 - 36x = 0

(-2x) (2x^2 + 7x + 18) = 0

Now set the factors equal to 0

-2x = 0 or 2x^2 + 7x + 18 = 0

x = 0

1. 9 bounds of carbon dioxide

2.  27 bounds of carbon dioxide

Step-by-step explanation:

So let's find a unit rate: 1 to 9

"Why is it 1:9?"

If I can find divide 72 pounds into 8 hours? What would I find? You would find the pounds for each other

Example: 72/8=9. So If 9 carbon dioxide per hour. I can do 3 hours is 27 pounds of carbon dioxide.

So to sum it up, 72/8=9 so 1:9 can be used to figure out any amount of pounds used in a certain number of hours. So If 3 hours, then 27 pounds.

Answer:

1. 9 pounds of carbon dioxide

Suppose that you live in a community that has 125,000 households. Among these households, 50,000 have traditional landline telephones while the remaining 75,000 only use cellular and / or VOIP telephones. We are going to select 100 households from your community at random without replacement. The first household selected does not have a traditional landline telephone. What is the probability that the second household selected will have a traditional landline telephone

Answers

Answer:

0.4 = 40% probability that the second household selected will have a traditional landline telephone

Step-by-step explanation:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

We have that:

125,000 households

50,000 have traditional landlines telephones.

The first household selected does not have a traditional landline telephone.

Now we have 125000 - 1 = 124,999 households, and 50,000 have traditional landlines telephones.

What is the probability that the second household selected will have a traditional landline telephone

[tex]p = \frac{50000}{124999} = 0.4[/tex]

0.4 = 40% probability that the second household selected will have a traditional landline telephone

What transformation rule would represent a shift of 3 units to the left 4 units down?
Group of answer choices

(x,y) –> (x – 4, y – 3)

(x,y) –> (x – 3, y – 4)

(x,y) –> (4x, 3y)

(x,y) –> (x + 3, y + 4)

Answers

Given:

Shift of 3 units to the left 4 units down.

To find:

The transformation rule.

Solution:

The rule of transformation is

[tex](x,y)\to (x+a,y+b)[/tex]          ...(i)

Here, a<0 if the figure shifts a units left and a>0 if the figure shifts a units right.

Similarly, b<0 if the figure shifts b units down and b>0 if the figure shifts b units up.

If a transformation represents shift of 3 units to the left 4 units down, then a=-3 and b=-4.

Putting a=-3 and b=-4 (i), we get

[tex](x,y)\to (x+(-3),y+(-4))[/tex]

[tex](x,y)\to (x-3,y-4)[/tex]

Therefore, the correct option is B.
