Calculate the following 1. a. An 110 g object has a height of 2 cm, a length of .42 dm, and a width of 3.7
cm.
Calculate its density. (Don't forget to convert in cm!)
b. If placed in a liquid with a density of 3 g/mL, will the object float or sink?
2. The mass of a rock is 45 grams. The volume of the rock is calculated using
water displacement. The original volume of water in the graduate cylinder was
60 ml. After putting the solid in the graduate cylinder, the water level rose to 75
ml.
a. What is the volume?
b. Calculate the density.

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

hope this !
