35300 tons of sugar beet we need in order to get 7,413 tons of sugar.
<u>Step-by-step explanation:</u>
Given that in sugar beet, there is 21% of sugar. Need to find out how much sugar beet we need in order to get 7,413 tons of sugar. Let we need x tone of sugar beet. So, according to the asked data, we have




x = 35300 tones
Any number above 1 gets greater, below 1 smaller (when above 0), while 1 itself remains the same. Negative numbers are more unpredictable.

Volume of cone =1/3.pi.r^2.h
Volume of cone =1/3.3,14.60^2.150
Volume of cone =565.200
if 1,413cm^3 in one minute
565.200 cm^3 in ? minutes
?.1,413=565.200
?=400 minutes
1 hour =60 minutes
? hour =400 minutes
?=400/60
?=20/3 hour
This is a right & isosceles triangle A =90° (Given) & AB = BC (given )
Apply Pythagoras
x² = 5(√2)² + 5(√2)² (since the 2 legs are equal)
x² = 5.2 + 5.2 Since (√2)² =2
x²=10 + 10 & x² = 20 & x=√(20) = 2√5 (the answer given are wrong.2√5 is the right answer)<u />
