Answer:

5,440 squares.

Step-by-step explanation:

We have been given that a chessboard has 64 squares. At a chess tournament 84 chessboards were used.

To find the number of squares on 85 chessboards, we will multiply number of squares on each chess board by number of total chess boards.

\text{The number of squares on 85 chessboards}=\frac{\text{64 squares}}{\text{Chess board}}\times \text{85 chess boards}

\text{The number of squares on 85 chessboards}=\text{64 squares}\times 85

\text{The number of squares on 85 chessboards}=5440\text{ squares}

Therefore, there are 5440 squares on 85 chess boards.

A toy company intends to ship out its entire stock of 10,254 toy trucks, and three times as many toy cars. If each box holds 35
svetoff [14.1K]
There are 10,254 toy trucks

and 10,254 * 3 = 30,762 toy cars.

In total, there are 10,254+30,762= 41,016 toys 

when we divide 41,016 by 35, the quotient is the number of the full boxes, and the remainder is the number of toys left.

41,016=35*1171+31


Answer: 1171 full boxes, 31 toys left for the last box

Burka [1]
<u></u><em>Hello there, and thank you for posting your question here on brainly.

______________________________________________________________
Answer: 128
</em>
<em>Why?
</em><em>______________________________________________________________
To find the volume of a cylinder, we have to use the formula lwh/3. The length is 8, width is 4, and height is 12. So we have to multiply all of those together, then divide by 3. (8 * 4 = 32) -> (32 * 12 = 384) -> (384/3 = 128) The volume is 128.

I think the answer is C.

First start by factoring, you should get (2n-3)(n-2)=0

Then start to solve for n.

2n-3=0

n-2=0

n=2, n= 3/2

I hope that helps.
