there are a floor is 48 square feet if 20% of the floor is covered with an area rug how much of the floor space remains uncovered

Step-by-step explanation:

20% of 48=9.6

48-9.6=38.4

Ans:38.4

38.4 square feet remains uncovered

Step-by-step explanation: 9.6 is 20% of 48

Solution: What is 20% of 48?

Y is 20% of 48

Equation: Y = P% * X

Solving our equation for Y:

Y = P% * X

Y = 20% * 48

Converting percent to decimal:

p = 20%/100 = 0.2

Y = 0.2 * 48

Y = 9.6

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
