Answer:
$80
Step-by-step explanation:
It's khan so you don't need the explanation but for those interested then here:
K=30x+20 - Kayla
S=35x+10 - Sara
60+20=80
70+10=80
So they match up at $80
12+54+131 - (12-(12))
197 -(12-12)
197-0
197
0.25 goes into 41 a total of 164 times. to get this answer you take 41 and divide it by 0.25 to get 164.
Answer:
2x+34
Step-by-step explanation: because you just have to double the equation because it already tells you the equation for halfway so just double it to get the full answer
You will need to use the Pythagorean Theorem and plug in the varibles. The rope is the hypotenuse of the right triangle formed, and the 40ft water is the vertical leg, which leaves the ocean floor to be the horizontal leg.[a^{2}+b^{2}=c^{2}\] \[a^{2}+40^{2}=140^{2}\] Then solve for a. \[a^{2}=18000\] \[a=134.164\]
