Alright, lets get started.
If Matthew wants to complete packages at an average rate of at least 39 packages per hour.
And they worked 4 hrs only due to picnic, yesterday, it means they have to make 
packages.
But they made only 112 packages means they are short of 
packages.
Suppose they are working today t hrs, and his department will complete 43 packages per hour today.
It means they are going to make 43 t packages today.
This 43 t packages includes those 44 too , which they are short of yesterday due to picnic.
So, average will be
(39 average given in question)
Cross multiplying
Adding 44 in both sides
Subtracting 39 t in both sides
Dividing 4 in both sides
t = 11 hrs
Hence they have to woth 11 hrs today : Answer
Hope it will help :)
Answer:
0.72 or 0.72866953788 0.7 0.72866953788
Possible values for y are<u> infinite</u>
<h3>Further explanation
</h3>
Trigonometry is the science of mathematics that studies the relationship between sides and angles in triangles
Given special angles of trigonometric functions, for example
In the trigonometric function equation y = cos⁻¹ 0, then the value of y can be determined:
y = cos⁻¹0
y = arc cos 0
cos y = 0
Then the value of y :
Or can be formulated :
⇒ y: arithmetic sequence
So there are infinite values for y

Area=height times base (for some prisms including cylinders)
vcylinder=hpir²
h=height
therefor pir²=base area
vcylinder=height times aeraofbase
given
h=9
v=324pi
324pi=9(basearea)
divide both sides by 9
36pi=areabase
the area of te base is 36pi square cm (put 36 in the blank since th pi is alredy there)
