For an electronic book retailer, the relationship between the price (p) of a book and the total number of words (w) in the book can be modeled by the equation w = 12,500p + 250. What does this equation indicate about books that are priced at $5.00? A. They tend to have 12,500 more words than books that are priced at $4.00.
B. They tend to have 12,500 more words than books that are priced at $2.50.
C. They tend to have 250 more words than books that are priced at $4.00.
D. They tend to have 250 more words than books that are offered for free.

the answer i believe is 27 units.

step-by-step explanation:

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
