3 dozen cookies = 36 cookies

Brother ate 0.25(36) or 9 cookies.

36 - 9 = 27 cookies remain.

Sara took (1/3)(27) or 9 cookies went to her neighbor.

There are now 18 cookies of which Sara ate 4.

So, 18 - 4 = 14.

There are 14 cookies left.

Find the volume of the composite figure. please!
Irina-Kira [14]
Volume= Length * width ( aka Base ) * height 

Break up the figure into easier figures, a small square and a bigger square.

Small square- 3*2*1 = 6 cm

Large Square- 7*6*1 = 42 cm

42 + 6 = 48 cm. But wait! You have to take one more step, which is minus-ing 6 from 48. Why? Notice that there is a little area where a side of the small square meets the bigger square. That little area is worth 3 cm ( length is 3, height is 1 cm ) times 2 ( 3 cm is one side, another 3 cm is the other side from the other square ) = 6 cm.

Your total answer should be 42. ( or 48, if your teacher doesn't count the area where the squares meet/join together ).

(Inequalities) what do you have to do when multiplying or dividing by a negative number?

When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative <u>YOU MUST FLIP THE INEQUALITY SIGN.</u>

Step-by-step explanation:

You are welcome.

And I hope this helps.      :)
