Step-by-step explanation:

Based on the table, Ashley collects 7 stickers a day.  If you want to know how many stickers she collects after 9 days, you need to do 7 x 9, which equals 63.

Hope that helped!  Good luck! :D

63 stickers

Step-by-step explanation:

Lets take this slow so you understand it! If you look at each day, there is a 7 sticker increase. Also, you can see in one day that she got 7 stickers. This confirms every one day, she gets 7 stickers, so how much would she get in nine days? You would do 7 * d, or the number of days. In this case, it would be 9. 7 * 9 = 63 stickers. The equation "7 * d" would work for any number of days, where d = days.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
