Yogita Ingle 5 years ago

Square is inscribed in circle so diagonal of square is equal to diameter of circle
dimeter of circle =2×7 =14
diagonal of square = diameter = 14
so ..area of square = 1/2 × (diagonal)2
=1/2 × 196
= 98 sq.cm

Here P = Rs 8000,   T = 1 year,    R = 9% p.a.

Interest is compounded half yearly,

∴       T = 1 year = 2 half years

         R = 9% p.a.=  half yearly

∵         Amount = 

                     = Rs 8000 

                     = Rs. 
                    
                     = Rs 
                
             CI = Rs 8736.20 - Rs 8000
 
                     = Rs 736.20

1. Represent these numbers on the number line.

(i) 7/4

(ii) -5/6

Solution:

(i) 7/4

Divide the line between the whole numbers into 4 parts. i.e., divide the line between 0 and 1 to 4 parts, 1 and 2 to 4 parts and so on.

Thus, the rational number 7/4 lies at a distance of 7 points away from 0 towards positive number line.

(ii) -5/6

Divide the line between the integers into 4 parts. i.e., divide the line between 0 and -1 to 6 parts, -1 and -2 to 6 parts and so on. Here since the numerator is less than denominator, dividing 0 to – 1 into 6 part is sufficient.

Thus, the rational number -5/6 lies at a distance of 5 points, away from 0, towards negative number line

Express each of the following as a fraction 4.5%

Shruti ? 5 years ago

54 is another way of writing 54 hundredths, or as a fraction, 54/100. Asking for a simplified fraction is asking you to reduce the numerator and denominator by any common terms. 54 and 100 are both divisible by 2, so we get to 27/50.

The sum of 10xy and -16xy = 10xy + (-16xy) = 10xy - 16xy = -6xy

2 km= 2000 m
Let the % be x.
x%×2000= 875
=> x/100×2000=875
=> 20x=875
=> x= 875/20
= 43.75
Therefore answer= 43.75%

i dont KNOW

Gaurav Seth 5 years ago

Answer:

16 years

Step-by-step explanation:

Let the principle be x.

Then amount will be 2x.

Interest= Amount - Principal = 2x-x=x

Time = 8 yrs  

R=?  

 

 

Now Amount will be 3 times i.e. 3x

So, Interest=Amount - Principal = 3x-x=2x

 

So, It will take 16 years to be three times at the same rate
