Solve i=Prt for t, if i=105, P=700, and r=0.05

Answers

plug i=105, P=700, r=0.05 in the equation i=Prt
105 = 700*0.05*t
105 = 35*t
divide both sides by 35
105/35 = 35*t/35
3 = t
t = 3

The number of tiles required to completely cover the floor is A) 144.

What are the area and perimeter of a rectangle?

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

We know the area of a rectangle is (length×width).

Given, His room is a rectangle, measuring 12 feet by 18 feet,

Therefore, The area of the room is

= (12×18) sq feet.

= 216 sq feet.

Also given one measures 3/4 inches by 2 inches.

Therefore the area of one tile is,

= [3/4×(2)] sq inches.

= 3/2 sq inches.

So, The number of tiles requires is the area of the room divided by the area of one tile which is,

= (216/(3/2)).

= 216×(2/3).
