A modern artist has been commissioned to create a geometric sculpture in Central Park. She has created a model to present to the Central Park Conservatory for approval. It consists of 3 identical prisms stacked on top of each other, see below. The scale of the model is 1.5 cm : 4.5 ft. Lenght= 9cm
width= 15.75
height=3.6cm
There are 3 regtangular prism
Each prism will be filled with colored foam. How much foam will be required to fill the actual sculpture? SHOW ALL YOUR WORK! Round to the nearest tent

what i would say the best answer is a. 40.5

step-by-step explanation:

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

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors
