Luluse se 15 For example. Sam calculated that a 35 mm x 33 mm rectangle has an

area of 1155 mm², whereas rounding 35 mm and 33 mm to the nearest

10 millimetres results in an approximate area of 40 x 30 = 1200 mm.

a A rectangle has length 47 mm and width which is larger than 20 mm

but rounds to 20 mm. The approximate area is larger than the actual

area. Find all possible widths of the rectangle.

To her surprise, Sam found a rectangle whose sides were not a multiple

of 10 millimetres but its actual area was the same as its approximate

area. She decided to call such a rectangle quirky.

b Explain why one side length of a quirky rectangle must round up and

the other side length must round down.

c Explain why one side length of any quirky rectangle is a multiple of

4 mm and the other is a multiple of 25 mm.

d Find the dimensions of all quirky rectangles with side lengths under

100 mm.

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

the homeowners insurance cost for a 115,000 wood frame house is 80,500.

step-by-step explanation:

it is given that the coverage rate for wood frame house is 0.7.

the value of wood frame house is 115,000.

.

homeowners insurance cost for a 115,000 wood frame house is

therefore the homeowners insurance cost for a 115,000 wood frame house is 80,500.

i dont know what you want me to answer for this but im guessing 2: 11?
