Answer:
The answer is 21 minutes
Step-by-step explanation:
We use the equation Xf = Xo + vt
1) At 1:00 PM, child one leaves the starting point heading north at a constant velocity of 6 mi/hr or .1 [mi/min] (divide by 60 to convert from [mi/hr] to [mi/min])
2) He walks for 15 minutes before kid 2 starts walking. In 15 minutes he is able to cover 1.5 [mi]
3) Now, child 2 starts walking and we know that when the range reaches 3 miles, they won´t be able to communicate. So the sum of the final position of child 1 and child 2 must be 3[mi]
- Child 1 final position =>
- Child 2 final position =>
4) Sum the equations and equate to 3
5) Substitute the values we already know
6) in 15 + 6 minutes they will be 3miles apart
7) In 21 minutes they will still be able to communicate with one another.
Answer:
2 square cm
Step-by-step explanation:
Given :
A square is inscribed in a circle whose radius is r = 1 cm
Therefore, the diameter of the circle is 2 r = 2 x 1
= 2 cm.
So the diagonal of the square is 2r.
Using the Pythagoras theorem, we find each of the side of the triangle is 
.
Therefore, the area of the square is given by 
= 
Hence the area of the largest square that is contained by a circle of radius 1 cm is 2 cm square.
I'm fairly certain that using that wire you can have the same area no matter what dimensions there are, but if you do the square root, or
of 19,001,900 then you get 4359.11688. So your dimensions are
4359.11688 x 4359.11688. To get area, do length x width to get <span>

Hi there!
345*28923+808(2829)
The first step put the problem into 2 parts, the first part is 345*28923
The second part is 808(2829)
The parentheses means to multiply that number that it touches.
Add the final 2 answers.
345*28923 = 9,978,435
808(2829) = 2,285,832
Now, add the answers.
9,978,435 + 2,285,832 = 12,264,267
Hope this helped!~
