First we need to know volume of cylinder,as cups are cylindrical .
Secondly, sink is half spehere,so volume of it is given=2000π/3in^3
So we need to know number of cups we scoop is going to equal to the volume of a sink,then only it will empty.

Fist cup has a diameter of 4 inch height 8 inch
Voulme of a cylinder=pi×r^2h
V=pi×2×8
V=32π
Now divide it to voulme of sink
Volume of sink/voulmeof a single cup
Numberof cup=2000π/3/32=20.48
We can take 21
Rest of part u can solve with the same method

Can someone plz help me
Colt1911 [192]

Answer:

x is less than or equal to negative 14.

Step-by-step explanation:

so for now we should pretend that the greater than or equal to is an equal sign, and simplify the problem to get x alone on a side

remove 5 from each side

-x/3=1/3-5

-x/3=14/3

multiply both sides by 3

-x=14

x=-14

so we can now replace the equal sign with the equal or greater to, so x is less than or equal to -14

Can someone help me with problem please? It’s special right triangle: decimal answers (Round to the nearest tenth)
DochEvi [55]

Answer:

h= 4.6, c=7.1

Step-by-step explanation:

First you need to know in a 30 60 90 triangle the sides ratios are x, 2x and x√3, and for 45 90 45 it is x, x and x√2

so <em>h</em> is 8/√3 and you rationalize the bottom so it becomes 8√3/3. when you solve this and round to nearest hundred it becomes 4.6. for the second one, it is 5√2 and when you solve this and round, it becomes 7.1
