Answer: the number of variations in sign = 3
Step-by-step explanation:
Let the finite sequence 1, –3, 2, 5, –4, –6 , the only pairs of consecutive terms for which the product of the two consecutive terms is negative are :
{1, –3} ; {–3, 2}; {5, –4} then
the number of variations in sign = 3
Jason is buying 2 hats and 3 scarves for each of his 4 children
so he is actually buying 8 hats and 12 scarves.
a hat costs 8.50 and a scarf costs 5.50
so you put it into a equation
8.50(h)+5.50(s) = P h = hat, s = scarf, P = pay
8.50(8)+5.50(12) = P
68 + 66 = P
P = 134

3 cause 1/8 times 24/1 = 24/8 divided =3
The area of the classroom is 8,671 in squared. you get this by multiplying base x height x width. You plug the same formula into the dollars he mentions and get 0.06890922 in squared. Than you divide the classroom dimensions by the dollar dimentions. that's 8,671 ÷ 0.06890922 = 125,832.21809795. rounding that to one decimal place, it would take $125,832.2 to fill up the classroom. (I might have gotten this wrong but I think this is the answer)
