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:
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.
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.
Step-by-step explanation:
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
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

Please help, I have been stuck for a while, it is about trig.
Answer: x=28, y=14
Step-by-step explanation:
This article gives the formula for finding the sides of a 30-60-90 triangle. https://blog.collegevine.com/complete-guide-30-60-90-triangle/
The gist of it is that the hypotenuse is 1, the short side is 2, and the long side is root3. Since there was a 14 with the root3, I multiplied the 1 and 2 for the other sides by 14 to get 28 and 14.

Consider the function given below.
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)
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.

The table shows the number of words per minute Josylyn can type. What is the missing value?
Answer:
52
Step-by-step explanation:
First, we want to see how we get from 104 to 156.
Looks like we add 52 to get the next.
104 + 52 = 156
156 + 52 = 208
Logically if we want to go back, we simply subtract 52.
104 - 52 = 52
Answer:
52

Lamont's empty backpack weighs 2 1/2 pounds. He puts 4 notebooks in it that each weigh 15 ounces. How many pounds does Lamont's backpack weigh now?
The answer is 6.252 pounds.
2 1/2 as a decimal is 2.5, and 15 ounces is equal to 0.938 pounds. Since there are 4 notebooks, you multiply 0.938 by 4, which is 3.752. Now, you just add 2.5+3.752=6.252

(2x^2 +x+4) (x+7) = 6x^3+29x^2+47x+28
with explanation
ASAP!!!
On a time crunch!!!!!
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

Answer:
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
2. 27 pounds of carbon dioxide
