Jane downloads album A. A has 11 tracks.
Each track on A costs the same.
The total cost of downloading A is £9.35
Jane also downloads album B and B has 14 tracks.
a) Work out the total cost in pounds (£) of downloading B.
Assume each track costs the same as a track on A.
(3)
+
b) In fact, compared to the cost of each track on A
the cost of 6 tracks on B is less by 7p each
the cost of 8 tracks on B is more by 7p each.
Work out the total cost in pounds (£) of downloading B.
(2)

a) total cost of downloading B is £11.90

b) total cost of downloading B is £12.04

see if that looks right lol

Step-by-step explanation:

a) £9.35 = 935p

935÷11=85p (cost per track)

85 x 14 = 1190p

1190p = £11.90

b) 85 x 6 = 510p

7 x 6 = 42p

510 - 42 = 468p

85 x 8 = 680p

7 x 8 = 56

680 + 56 = 736p

468 + 736 = 1204p

1204p = £12.04

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
