Okay so this is easy conversion.
40 quarters=10$
60 dimes =24 quarters
30 dimes= 12 quarters=3$
200 dimes=80 quarters
For this question, this might help.
17.47 degrees is 17 + 0.47 degrees
If you are using minutes instead of decimal degrees, multiply the fraction by 60. So,
0.47 degrees * 60 minutes per degree= 28.2 minutes
Now you have 17 degrees 28.2 minutes
but you can replace fractions of a minute with seconds
0.2 minutes * 60 seconds per minute= 12 seconds
So the answer for
17.47º is equal to 17º 28' 12".
I hope this helps.
Y= -2+21
This is because the slope needs to be the negative reciprocal of 1/2 so the slope is -2 then you take the point (5,11) and plug that an the -2 into y=m(x)+b and you solve for b. In the end you get 21
