In sugar beet, there is 21% of sugar. How much sugar beet do you need in order to get 7,413 tons of sugar?

almond37 [142]

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

$21 \% \text { of } x=7413$

$\frac{21}{100} \times x=7413$

$0.21 \times x=7413$

$x=\frac{7413}{0.21}$

x = 35300 tones

why do whole numbers raised to an exponent get greater while fractions raised to an exponent get smaller?

ehidna [41]

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

A hose dispenses 1,413 cm³ of water every minute into a cone with a radius of 60 cm and a height of 150 cm. How long will it tak

QveST [7]

I hope this helps you

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

Find the value of x. <br><br> A. First Image<br> B. 5<br> C. 10<br> D. Second Image

kirza4 [7]

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 />
