Ablueprint is a scale drawing of a building. the dimensions of the blueprint for patricia's doll house are 1/4 of the measurements of the actual doll house. the floor of the doll house has an area of 864 square inches. if the width of the doll house is 2/3 the length, what are the dimensions of the floor on the blueprint of the doll house?

Length: 9 inches.

Width: 6 inches.

Step-by-step explanation:

Find the dimensions of the floor of the doll house.

Apply the formula:

Where  A is the area, l is the lenght and w is the width.

You know that:

Then you can solve for l:

Then the width is:

Therefore, the dimensions of the floor on the blueprint of the doll house are:

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
