Ok, first of all, it is important to understand that this function would depend on 2 variables; the number of dollars (x) and the number of pennies (y). Every dollar is equivalent to 100 pennies. So, if we are given x dollars, we have 100*x pennies. If we also have y pennies, we still get y pennies. We need to add these two to get the total amount of pennies. Thus, the correct function is:
f(x,y)=100*x+y
8hrs = 480mins
6hrs = 360 mins
472/480 = 0.983...
0.983... x 360 = 354
D) 354
500 seconds is greater. Since there are 60 seconds in one minute you would multiply 60 and 8.
60x8= 480
Answer:15.5 because you have to take away some point
Step-by-step explanation:
1) a=5+√29 or a=5−√29
2) x=1 or x=−21
3) x=4 or x=6
4) x=9+√146 or x=9−√146
Hopefully that helps you ❤
