In the number 203,500, the last two zeroes are called terminal zeroes. If the multiplication 30x40x50x60x70 is done, how many terminal zeroes will the product have?

6 terminal zeros

Step-by-step explanation:

6 zeroes

Step-by-step explanation:

When you multiply numbers with zeroes, you multiply the non-zero digits and add the zeroes left. 30x40x50x60x70 will have 5 zeroes because every number ends in a zero. But you have to add one more zero because 4x5=20, and 20 ends with a zero.

Therefore, the answer is 6 zeroes.

the answer is 0.071

good luck! : d

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
