Here first we have to understand which place is 10 thousand.
6- hundred thousand
2- ten thousand
0- thousand
0- hundred
0- ten
0- one
so as we can see 2 is in ten thousands place.
Now rounding ten thousands place is done by looking up to thousands place.
If the digit at thousands place is 5 or greater than 5 then we change our ten thousands value to one digit higher else it remains same.
Here we have 0 at thousands place , which is less than 5 , so we keep the number as it is.
Answer: 620, 000
Answer:
ok....let me try .....
<h2>..ok bro....sorry don't be angry
<em><u>b</u></em><em><u>j</u></em><em><u>h</u></em><em><u>u</u></em><em><u>j</u></em><em><u>j</u></em></h2>
R=10
because 10 divided by ten =1 +4 =5
Answer: 
Step-by-step explanation:
For this exercise it is important to know the definition of "Dilation".
A Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) and the Pre-Image (The original figure before the transformation) have the same shape but have different sizes.
If the Dilation is centered at the origin, and knowing the scale factor of
, you need to multiply each coordinate of the point T by the scale factor in order to find the coordinates of the Image T'.
Knowing that the point T has the following coordinates:

You get that the coordinates of the Image T' are the shown below:

Height covered by the plane=h= 500 feet
Distance covered by the plane along the ground=d= 2 mile
Now, convert the mile into feet,
1 mile = 5280 feet
2 mile = 10560 feet
Now, use the formula
h= d tanθ
tanθ= h/d
tanθ= 500/10560
tanθ= 25/528
Take the tan⁻¹ on both side,
θ= tan⁻¹(25/528)
θ =2.71°
