Which number, rounded to the nearest hundred , is zero
a) 94
b) 68
c) 52
d) 31

d) 31.

Step-by-step explanation:

We are asked to choose the number that will result in 0, when rounded to the nearest hundred.

Let us see our given choices one by one.

a) 94

We can see our given number has 9 tens and tens place is greater than 5, so, we will round up our answer to nearest hundred that is 100. Therefore, 94 is not a correct choice.

b) 68

We can see our given number has 6 tens and tens place is greater than 5, so, we will round up our answer to nearest hundred that is 100. Therefore, 68 is not a correct choice.

c) 52

We can see our given number has 5 tens and tens place is 5, so, we will round up our answer to nearest hundred that is 100. Therefore, 52 is not a correct choice.

d) 31

We can see our given number has 3 tens and tens place is less than 5, so, we will round down our answer to nearest hundred that is 0. Therefore, 31 is the correct choice.

no, because the sides are not congruent
