I ONLY HAVE A FEW MINUTES TO POST LIKE 7 QUESTION PLEASE HELP SOMEONE!
haha go for it
cmon fire away
i think she's already screwed, her online exam has probably ended at the top of the hour lol...but if not fire away like him said lol
A CELLUAR PHONE COMPANY OFFERS A CONTACT C, IN DOLLARS, OF T MINUTES OF TELEPHONE IS GIVEN BY C=0.25(T-300) + 79.95, WHERE IT IS ASSUMED THAT T => 300 MINUTE. WHAT TIMES WILL KEEP COSTS BETWEEN $118.45 AND $164.70?
What is this bovice?
I think you know something about this mysterious college girl
haha
i'm just answering her question
What is all this online test. Could you please tell me
You know this college girl, she comes to this site, and asks for answers, and only answers and no explanations
I didn't quite understand what she is up to
so T=454 will make C=118.45
But I felt she is doing something she must not do
T=639 makes C=164.70
so the answer is 454 < T < 639
so can i have my medal now??? (:
why did I 301.54 and 303.39
because you fail at basic algebra? i dunno....i thought you were in a hurry...now chop chop!!!
TWO ANGLES ARE COMPLEMENTARY. THE SUM OF THE MEASURE OF THE FIRST ANGLE AND ONE-FOURTH THE SECOND ANGLE 77.55 DEGREE. FIND THE MEASURE OF THE ANGLES? WHAT IS THE MEASURE OF THE SMALLER ANGLE? ALSO WHAT IS MEASURE OF THE ANGLE?
the one before should be 301.54<T<303.39
A+B=90 A+B/4=77.55 Find A where A is your fist angle Find B where B is your second angle
for the cost to be between $118.45 abd $164.70 telephonig time be between ? minutes and ? minutes.
myininaya is wrong
454 < T < 639
118.45 = 0.25(T-300) + 79.95 subtract 79.95 from both sides.... 38.50 = 0.25(T-300) divide both sides by 0.25 154 = T - 300 add 300 to both sides T = 454
C=25(T-300)+79.95 we want C to be between 118.45 and 164.7 118.45<C<164.7 118.45<25(T-300)+79.95<164.7
I have been using this all day and I cant even get a better grade but yet you guys really know what the answer are huh funny.
now do the same thing for the upper limit of C C = 164.70
oh i see i misread the Cost sorry
oh yeah the equation is C = 0.25(T-300) + 79.95
i seen 25 and not .25 my mistake
anyways the second part of the answer would be 164.70 = 0.25(T-300) + 79.95 84.75 = 0.25(T-300) 339 = T-300 T = 639
w00t i got my medal :)
I am sorry that I am stupid sorry
