Answer:
6
Step-by-step explanation:
6+(6+2)+(6×3)=32
32÷(1+1+3)=6•••••2
So it's 6 and 6+2 and 6 times 3
which is 5 of number 6 plus 2
=6+(6+2)+(6×3)
=6+8+18
=32
Answer:
129 :)
Step-by-step explanation:
The mass of b equals the mass of d so
24(10-x)=6(x+15)
240-24x=6x+90
30x=150
x=5
mass of d is 6(5+15)=6*20=120
mass of c=180-mas of d=180-120=60°
6 = 5r - 14
6 + 14 = 5r
20 = 5r
r = 4
Answer:
dv = surface area * dh
so
dv/dt = surface area * dh/dt
width at surface = 40 + (80-40)(30/40)
= 40 + 30 = 70 cm = 0.70 m
so
surface area = 9 * .7 = 6.3 m^2
so
.3 m^3/min = 6.3 m^2 * dh/dt
and
dh/dt = .047 meters/min or 4.7 cm/min
