Answer:

3 pieces

Step-by-step explanation:

Given: Figure

To find: Number of 8.5 in. ×  11 in. pieces used to cover the floors  of a room and a hallway in  her dollhouse

Solution:

In the given figure, AC = 22 in.

AB + BC = 22 in.

AB + EF = 22 (As BC = EF being opposite sides of rectangle)

AB + 10 = 22

AB = 22 - 10 = 12 in.

Area of rectangle ABGH = AB × AH = 12 × 5 = 60 square inches

(area of rectangle = length × breadth )

CE = CD + DE = AH + GF (As CD = AH and DE = GF)

CE = 5 + 15 = 20 inches

Area of rectangle BCEF = BC × CE = 10 × 20 = 200 square inches

(BC = EF = 10 in.)

Total area of the figure = Area of rectangle ABGH + Area of rectangle BCEF = 60 + 200 = 260 square inches

Area of pieces of felt = 8.5 × 11

So,

Number of pieces required = Total area of the figure / Area of pieces of felt  = \frac{260}{8.5(11)} =2.78 \approx 3 pieces

What is the area of this triangle?
vlada-n [284]

Answer:

91.44 (or 91.4375)

Step-by-step explanation:

The formula for finding the area of the triangle is bxh/2

19 1/4 = 19.25, 9 1/2 = 9.5

So, 19.25(b)x9.5(h)=182.875

182.875/2= 91.4375

Round the answer: 91.44

A hotel room that is advertised at $120 per night. You notice in the fine print that there will be an additional 18% tax on the
Rudiy27

The tax and the total per night is calculated with $120 * 118%. You then will get $120*1.18, which is, $141.6. To get the tax alone, you can multiply $120 to 18%, and get $21.6.

Remember that percentages are basically a fraction over 100. (Ex. 18% is 18/100. You can simplify it to 0.18)

It will cost $21.6 in tax each night alone, but will cost $141.6 in total.
