Sin theta of a line that bisects quadrant 2

1 answer:

6 0

Q2 goes from 90-180 degrees from the positive x-axis.
So if the line bisects Q2, theta=(90+180)/2=135 degrees.
Sin(135)=+sin(180-135)=+sin(45)=sqrt(2)/2=0.70710678 approx.

There are 31 coins of dimes and quarters. If the number of dimes is 5 more than the number of quarters, how many quarters are th

emmasim [6.3K]

Answer:

13 Quarters and 18 Dimes

Step-by-step explanation:

Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). Give x and y a break, and make it easier to remember which is which.

D + Q = 31

D = Q + 5

Therefore:

D + Q = 31

(Q+5) + Q = 31

2Q + 5 = 31

2Q = 26

Q = 13

Then D = (13+5) or 18

================

Check:

D + Q = 31 ?

18 + 13 = 31 YES

----------------------

D = Q + 5 ?

18 = 13 + 5 YES
