Area of a room is 500m square. The cupboard takes 6% of the room’s area a:what is the area of the cupboard
b:The table is 1/10 of the room. Calculate the area of the table.
c: bed has an area of 110m square. What is the percentage of the room is the bed?

Step-by-step explanation:

Let breadth be x m

So, length = 2x m

So, 2*4*(2x+x) = 120m

or, 3x = 15

or, x = 5

So, area of floor = 5*(2*5)m2 = 50m2

Step-by-step explanation:

step 1. 500(.06) = 30m^2 (area of cupboard)

step 2. 500(1/10) = 50m^2 (area of table)

step 3. 110/500 = .22 = 22% (percentage of the bed area in the room).

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
