A. There are 3 feet per yard.
so... 390/3=130 yards
Answer:
3321
Step-by-step explanation:
Zero would mean the sea level. Since three miles below sea level is -3, and 0-3 is -3.
Since it's perpendicular to the line with the slope 5, you take the reciprocal of 5 which is 1/5 and change the sign: -1/5. So you have the equation: y=-(1/5)+b. To find b you substitute x and y for the coordinate (10,8).
y=(-1/5)x+b
8=(-1/5)10+b
8=(-10/5)+b
8=-2+b
<u>+2 +2</u>
10=b
So your new equation is: y=<u>1x</u>+10
5
