The total cost after tax to buy floor tiles is represented by 14f + 0.097(14f), where f represents the number of square feet of

Firdavs [7]

Answer:

exActual room size: 8 ft 7 in x 5 ft 2 in

Convert to inches, actual room size: 103 in x 62 in

103" x 62"= 6386 inches / 144 (1 sf) = 44.50 sf + waste factor (44.50 x 1.10) = 49 sf

The same method is used when measuring walls. Measure the area to be tiled on each wall. Add them together and figure the square footage. Add your waste factor and this is the amount needed.

Most vertical applications will require trim pieces which have finished edges, this requires a linear measurement. Trim pieces will be used:

1. Where a tiled surface ends on an open wall leaving an exposed tile edge,

2. Where a vertical surface meets a horizontal, like on the edge of a countertop,

3. Where a vertical surface turns a corner, like on the outside corner of a wall.

Trim pieces and decoratives are typically sold by the piece. To figure the quantity you have to establish the length of the trim piece (i.e. 6" bullnose, 8" decorative liner), then the rule is: Linear Inches/Piece Length = Quantity

The figure below is an isosceles triangle. What is the perimeter of the triangle in terms of a

professor190 [17]

Hey there! I'm happy to help!

-------------------------------------------------------------------

WHAT IS THE PERIMETER?

The perimeter is just the distance around a shape. If you put a fence around a field, the length of all of the fencing is the perimeter.

-------------------------------------------------------------------

WHAT IS AN ISOSCELES TRIANGLE?

An isosceles triangle is a triangle that has at least two sides that have the same length! In our triangle, we have two sides that have the value of a, so that makes it isosceles!

-------------------------------------------------------------------

THE SOLUTION

In our problem, we want to find the perimeter of this triangle in terms of a and c. When we say in terms of, it just means that our answer will include a and c instead of finding a number value.

The perimeter is the sum of each of these sides. This means that the perimeter is a+a+c, which is also 2a+c.

Therefore, the perimeter of this isosceles triangle is 2a+c.

I hope that this helps! Have a wonderful day! :D
