Answer:
The area is approximately 1256.64 The circumference is approximately 125.66
Step-by-step explanation:
This is because to find the area of a circle you square the radius and multiply by Pi. To find circumference, you can multiply the Diameter (twice radius) by Pi.
Answer: -3
Solution:
Let n be that number.
So,
Three less than 3*no = 3 more than 5*no
3*n-3=5*n+3
5n-3n=-3-3
2n=-6
n=-3
6.3 feet per 60 seconds so if you want feet per one second you need to divide 6.3 and 60 which is 0.105 ft per 1 sec.
Answer:
2x+5y=-15
ax+bx=c
slope=-a/b so -2/5 matches up with point slope form
then to get y intercept substitite x in point slope for 0 and solve for Y to get -3
then do c/b to get y intercept, so -15/5, which equals -3.
Solve by Elimination:
6y+5x=8
2.5x+3y=4
Multiply the second equations by 2:
5x+6y=8
we know see that both equations are the same line, this means that there is an infinite amount of solutions to the equation
