You can set it up like:
400/2.5 = 600/x; now cross multiply
400x = 2.5(600)
400x = 1,500; now divide both sides by 400 to isolate the x, and you get x = 3.75 hours
Answer:
X=7/2 Y=1
Step-by-step explanation:
4X-Y=13
4X-13=Y
2X-3(4X-13)=4
2X-12X+39=4
-10X+39=4
-10X=4-39
-10X=-35
X=7/2(-35/10)
Y=4(7/2)-13
Y=14-13
Y=1
Answer:
3.14
Step-by-step explanation:
A quarter circle is just 1/4 of an entire circle's area. Since you know the radius is two, simply find the area of the entire circle and divide by 4.
4pi/4 = pi
Step-by-step explanation:
