Quincy feeds his dog 2.75 cups food each day each cup of dog food costs $1.25. he multiplies the numbers together to determine how much it costs to feed his dog each day. which expression will result in the best estimate for quincy to use to check his multiplication?

C) 3 x 1

Step-by-step explanation:

First, you round 2.75 to 3 because of the rounding rule- "If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up." Then you round 1.25 to 1 because of the rounding rule. Then you get 3 x 1!

Hope this helps-

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
