Hi
arithmetic serie mean that to change from a rank to an other, you add "r"
So : if 6 is S1, and 2 is pace,
<u>then you need 8 hops to go from S1 to S9.</u>
<u> so you 'r going to add the reason 8 times. </u>
so : S9 = 6 + 8 * 2 = 6 + 16 = 22
conclusion : S9 = 22
Answer:
54.198
Step-by-step explanation:
Answer: Samantha
Step-by-step explanation:
Two ways you could solve this percents or fractions.
Percents
Peter: 4/5 = 80%
Samantha: 7/8 = 87.5%
Fractions
Set the denominator equal to each other
the common denominator would be a multiples to both 5 and 8 which is 40.
Peter: 4/5 = 32/40 because 5 times 8 is 40 and what you do to the denominator you do to the numerator so 4 times 8 is 32.
Samantha: 7/8 = 35/40 because 8 x 5 = 40 and 7 x 5 = 35.
Then compare and 35/40 is greater so Samantha.
-7≤ r+3 ≤+7
-7-3 ≤ r ≤ 7-3
-10 ≤ r ≤ 4
Answer:
31 cm
Step-by-step explanation:
The perimeter is the sum of the sides so the answer is 8 + 10.5 + 9 + 3.5 = 31 cm.
