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
Step-by-step explanation:
Answer:
x=25
Step-by-step explanation:
these angles are of the same measure, so i set the two values equal to eachother. it looks like
75=(4x-25)
and solve for x
I HOPE THIS IS RIGHT!! have a great day
Answer:
1/4!! See ya! (Mark Brainliest)
Step-by-step explanation:
Answer: The smallest angle is 35°
Step-by-step explanation:
1 angle: 2x
smallest angle: x
third angle: 2x + 5
all angles in a triangle add up to 180 degrees. Therefore,
2x+x+2x+5 = 180
5x+5=180
5x+5(-5)=180(-5)
5x = 175
5x/5 = 175/5
x = 35
The smallest angle is 35°
