Answer:
it is a it the first one. 7/13
5+2=7, so the first blank is 2.
For the second blank, you just need two numbers in the box that when added, equals 7. (So 1,6 or 3,4)
2t/5=8t/20 (both numbers multiplied by 4)
t/4=5t/20 (both numbers multiplied by 5)
3=60/20
⇒ 8t/20 - 5t/20= 60/20
3t/20=60/20
⇒3t=60
t=60:3
t=20
I hope you understand !
Answer:
Volume of a sphere = 4πr³/3
r=10
V = 4πx10³/3
=4000π/3
V= 1333.33π (in terms of pi)
or
V= 4188.79(Nearest Hundredth).
two points are (0,0) and (100, -800)
m = (y2-y1)/(x2-x1) = (-800-0)/(100-0) = -8
point slope form of the line is
y-y1 = m(x-x1)
y-0 = -8 (x-0)
y=-8x
this is in slope intercept form now
y=-8x
