Archimedes is known for mathematics.
Assume that Cody was x cm tall on his first day at school last year.
Assume that Cody is y cm tall on his first day at school this year.
This year, Cody became 10% taller.
10% is equivalent to 0.1
This can be translated into the following:
y = x + 0.1x
We are given that y = 165 cm.
Substitute in the equation to get x as follows:
165 = x + 0.1x
165 = 1.1x
x = 150 cm
Based on the above calculations, Cody was 150 cm tall on his first day at school last year.
<u>1</u>18.380 to the nearest hundred is <u>1</u>00
The 1 that I underlined represents the hundreds place of a number, and since the number in the tens place ex.) 2<u>1</u>2.31 is also a 1, then you round down to just 100.
ex.) round to the nearest hundred: 492.341 The answer to this would be 500, since the number in the tens place is a 9 so you round up to the next hundred.
The formula to finding the volume would be v=l•w•h so then insert the values into that. You’re left with v=10•8•5. Multiply them together and you get 400cm cubed. That’s how much sand you’d need to fill the box.
