Annie rounds 280.05 to the nearest hundred. Bobby rounds 280.05 to the nearest ten.

Ciro rounds 280.05 to the nearest integer.

Denise rounds 280.05 to the nearest tenth.

What is the sum of Annie's answer, Bobby's answer, Ciro's answer, and Denise's answer?

280.1

Step-by-step explanation: so the reason this is right is because any number under 5 would round it down but 5 and up and it would round up.

-3

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
