Round 939,515 to the nearest ten.

939,520

Step-by-step explanation: To round 939,515 to the nearest ten, we first find the digit in the rounding place which in this case is the 1 in tens place.

Next, we look at the digit to the right of of the 1 which in this case is 5.

According to the rules of rounding, since the digit to the right of the rounding place is greater than or equal to 5, we round up.

This means that we add 1 to the digit that's in the rounding place so 1 will become 2 and we change all the digits that appear to the right of the rounding place to 0.

So 939,515 rounded to the nearest 10 is 939,520.

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
