Answer:
34191.7πin³/sec
Step-by-step explanation:
Volume of circular come = 1/3pi x r² x h
When we differentiate this formula we have
dv/dt = 1/3π[r²dh/dt + 2rhdr/dt]
We have the following information
r = 138
H = 143 inch
dr/dt = 1.4
dh/dt = -2.8
When we plug into the formula
1/3π[130² x -2.8 + 2x138x143x1.4]
= 34191.7πin³/sec
$2.50+3x=$9.25, if you need to work it out, then you do $9.25-$2.50. You take your answer and divide by three... whatever your solution is, equals X. There you go!
Answer:
3/4, 5/6, 8/10 this is in fraction form though. just change it to 3:4
The answer is 2-7x I'm 100% sure
The value of angle x is 113 degrees and y is 67 degrees.
What is angle?
In euclidean geometry, an angle is that the figure shaped by 2 rays, referred to as the perimeters of the angle, sharing a typical end point, referred to as the vertex of the angle. Angles shaped by 2 rays exist the plane that contains the rays.
Main body:
Given ;
∠C = 62°
∠A =51°
according to triangle sum property: Sum of angles of triangle is 180°
Using it,
62° +51° +∠y = 180°
113°+ ∠y =180°
∠y = 67°
∠x is equal to the sum of interior opposite angle ,so using it we get:
∠x = 61°+52°
∠x = 113°
Hence the value of ∠x is 113 degrees and y is 67 degrees.
