It depends on how many football cards and basket ball cards you have
Answer:
-14.4<or=z
Step-by-step explanation:
-8-6.4or = z+6.4-6.4
-14.4_<z
Answer:
3x and 2x
Step-by-step explanation:
There are 2 terms with an x in it, so they are "like".
y is the odd one out.
We'll convert them all to approximate percent to compare.
Tricia 17%
Anchara, 4/25 = 16/100 = 16%
Julia reduced (16- 13.5)/16 = 2.5/16 = 5/32 = 15.625%
Tricia reduced her time by the biggest percent.
1)Rewrite the table:
70, 49, 34.3, 24.01, 11.807
2) write the quotient of each number by the number before & notice the value:
49/70= 0.7
34.3/49 = 0.7
24.01/34.3 =0.7
16.0807/24.01 = 0.67 ≈0.7
You notice this is a geometric progression with r 0.7
The last term in a GP =ar^(n-1)
a=70; r= 0.7 n-1= number of terms (days -1)
For last term = 1 ==> then 1=70(0.7)^(n-1)
1/70 = (0.7)^(n-1)
log(1/70) =log[(0.7)^(n-1) ==> log1 - log 70 = (n-1) log(0.7) & you will find that it need 11.92 days to equal on & to be less than it will necessitate 12 Days
