What's a hundredth?

it's like this:

0.01

so where is the hundred place in this number?

389.9<em>9</em>3

it's the 9 that i made boldface

so to round to this number we delete everything after it, asking ourselves if the number after it is 4 or less? yes! so we can just delete it without changing anyway

389.99

Answer:

Volume of composite is 483 $mm^3$

Step-by-step explanation:

We need to add the volume of a rectangular prism (7 mm x 12 mm x 3 mm) to a semi-cylinder (of radius 3.5 mm and height 12 mm):

Volume of the prism = 7 x 12 x 3 $mm^3$ = 252 $mm^3$

Volume of the semi-cylinder = $\frac{\pi\,\,R^2\,\,H}{2} = \frac{\pi\,\,(3.5)^2\,\,(12)}{2} =230.907 \,\,mm^3$

Therefore the sum of both volumes gives:

(252 + 230.907) $mm^3$ = 482.907 $mm^3$

WHich can be rounded to the nearest whole number as: 483 $mm^3$

a city has a population of 370000 people. suppose that each year the population grows by 4,5%. what will the population be after

sashaice [31]

Population=370000

Population growth=4.5%

Increase in Pop growth in a year=

( {100+4,5}/100 )×370000= 386,650 people

Therefore growth in 15years=

386650×15 =

5,413,100 people
