Answer:
1.1(for infinity) or 0.9
Step-by-step explanation:
it depends if you do 90/100 or 100/90
90/100 = 0.9
100/90 = 1.1(for infinity)
so sorry i couldn't figure out specifically what to divide but i hope both of these answers helped you!
Hello :
cos60 = cos(-60)=0.5
1 nickels =$0.05
1 dime= $0.1
let the number of nickels be x and that of dimes be y.
total number of coins is given by:
x+y=42
hence:
y=42-x.......i
total amount of cash will be:
0.05x+0.1y=3.30.........ii
substituting i in ii we get:
0.05x+0.1(42-x)=3.30
0.05x+4.2-0.1x=3.3
-0.05x=-0.9
x=-0.9/(-0.05)
x=18
hence the the number nickels is x=18, the number of dimes will be y=42-x=42-18=24
B is the answer to the problem.
Each equation is a line and therefore will intercept each other at a single point. These points converge where the two y values are the same as that will produce the same coordinate. Therefore, we find the place where the two y values are equal to each other by setting the equations equal to each other.
