X= total acres on farm

x * 21%= 168
move decimal 2 places to the left to go from percent to decimal form
x * 0.21= 168
divide both sides by 0.21
x= 800 acres

ANSWER: There are a total of 800 acres on the farm

Hope this helps! :)

Is 21.192 a rational or irrational
Klio2033 [76]
Rational number is something that does not have a decimal number going to infinity or something that can be written as a fraction

21.192 can be written as 21 192/1000 so yes its rational

i.e. √2 goes on forever and cannot be written as a fraction. so no it is not rational. it is irrational just like π.

Hope this helps :P

a building with a height of 32m casts a shadow that is 20m long. a person standing casts a shadow that is 1.2 m long how tall is
wlad13 [49]
Most of the information's required for solving the question is already given in the question.
Height of the building that casts a shadow of 20 m = 32 m
Then
Height of the man that casts a shadow of 1.2 m = (32/20) * 1.2 meter
                                                                             = 3.2 * 1.2 meter
                                                                             = 3.84 meter
So the actual height of the person casting a shadow of 1.2 meter is 3.84 meters. I hope that the procedure used for solving the problem is easy enough for you to understand. You can definitely use this method in future for solving problems of similar type without requiring any additional help from outside.

A joker cap is in the form of a right circular cone of base radius 10.5cm and height 36cm. find the area of sheet to make 20 suc
rusak2 [61]

We know that

l² = r² + h²

l² = (10.5)² + (36)²

l² = 110.25 + 1296

l² = 1406.5

l = √(1406.5)

l = 37.5 cm

Now,

CSA of cone = πrl

=> 22/7 × 10.5 × 37.5

=> 22 × 1.5 × 37.5

=> 1237.5 cm²

Area of 20 caps = 20 × 1237.5

=> 24750 cm²
