Brainly isn’t letting me insert a picture but the anwser is y<2+3x/4
the complete question in the attached figure
Volume of the sand V=(1/3)*h*π*r²
we have that
h=30 mm
r=10 mm
v=(1/3)*30*π*10²=1000≈3140 mm³
the rate is 50 mm³/seg
50 mm³--------------------------------------> 1 seg
3140 mm³-------------------------------- X
x=3140/50=62.8 seg
the answer is 62.8 seg
Thats uhhhhhh..... thats pretty cool.
Answer:
The listener is approximately 71.414 feet far from the whisperer.
Step-by-step explanation:
We must remember that two fundamental variables for every ellipse are the major semiaxis (
) and the minor semiaxis (
). The major semiaxis equals a half of the length of the whispering gallery, whereas the minor semiaxis equals a half of the width of the whispering gallery. These are:
and 
The distance between both whisperers (
), measured in feet, is two times the distance between center and any of the foci (
), measured in feet, whose valued is obtained by using this Pythagorean identity:

If
and
, then:




The listener is approximately 71.414 feet far from the whisperer.
Answer:
-18 - 24y.
Step-by-step explanation:
6(-3-4y)
We use the distributive law to give:
6 * -3 + 6* -4y
= -18 - 24y.
