[(25-11)+(15-9)] divided by 5

Answer:

667.8 cm³

Step-by-step explanation:

To find the volume of a box;

simply multiply the length, width, and height - and you're good to go! For this case, the box is 9x7x10.6 cm, then the volume of a box is 667.80 cubic centimeters. For dimensions that are relatively small whole numbers, calculating volume by hand is easy. Therefore, the volume of the box is 667.8 inches cubed

Answer:

81 million

Step-by-step explanation:

A = Pe^rt

Let's break this equation down.

A is the total you will have.

P is the starting value.

R is the rate

T is the time.

Let's find the rate first.

74000000 = 70000000e^7r

Divide each side by 70mil

74000000/70000000 = e^7r

Then take the ln() of each side.

ln(74000000/70000000) = 7r

0.0556 = 7r

r = 0.0079

Now we can find how many people will be there in 2010.

A = 70,000,000e^(19 * 0.0079)

A = 81336530.2373

Now we round to the nearest million, leaving us with 81 million.

Answer:

61 cm for each book shelf.  

Step-by-step explanation:

First it gives you the width of the boxes so you add them together

132 + 108 + 94 = 334

so 334 cm has already been used out of 456 cm.  

Next you will 456 - 334 = 122 cm left over

if they are building 2 book cases you with take what cm's you have left and divide it by 2

122 / 2 = 61

So that means each book case will be 61 cm's wide
