small frames ($8): s
large frames ($15): L
Cost: 8s + 15L = 239 ⇒ 1(8s + 15L = 239) ⇒ 8s + 15L = 239
Quantity: s + L = 22 ⇒ -8( s + L = 22) ⇒ <u> -8s -8 L = -176 </u>
7L = 63
L = 9
Quantity: s + L = 22 ⇒ s + (9) = 22 ⇒ s = 13
Answer: 13 small frames, 9 Large frames
1.98 x 10^-12 1.98
------------------ = ---------- x 10^-10
3.6 x 10^-2 3.6
=0.55 x 10^-10
=5.5 x 10^-11
Answer:
"faster"
Step-by-step explanation:
Let's put the rates of Eli in WORDS PER MINUTE (the normal measure for typing).
First, we need to convert 1/10th of an hour to minutes. Since there are 60 minutes in an hour, we need to multiply 1/10 with 60. So we have:
1/10 hour = 1/10 * 60 = 6 minutes
Now, converting 1/12th of an hour to minutes in the similar manner, we have:
1/12 hour = 1/12 * 60 = 5 minutes
Hence, first time his wpm (words per minute) is ----- 240/6 = 40 wpm
Also, second time his wpm (words per minute) is ------ 240/5 = 48 wpm
2nd time he was faster (since 48 wpm is greater than 40 wpm).
He was faster on his second attempt.
5 is it I think this crazy
