this experiment will demonstrate how the volume of water changes when it changes from liquid to solid state, or freezing.

the materials for this experiment are a large round balloon, water, marker, tape measure, and freezer.

our job is to observe the experiment and collect your own data from this demonstration. start with a round water balloon filled with water.

make sure that there is no air in the water balloon.

draw a line around the equator, or center of the balloon.

measure the circumference of the balloon where you drew the line with the tape measure.

the line around the balloon is measured with a tape, the results are 39.5 cm. then put the balloon in the freezer for 24 hours, until it is completely frozen.

the balloon is now frozen, again measure the circumference of the balloon around the line you drew before.

the line around the balloon is now 41.2 cm.

compare the circumference of the balloon before and after freezing. what is the percent increase in this measurement?

 17%

Step-by-step explanation: Take away 39.5 cm from 41.2 cm and you get 1.7 then you move the decimal in till it turn into a percent and you have 17%.

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
