1.06×2.29=?????????????????
mario62 [17]

Answer:

2.4274

Step-by-step explanation:

This is just a simple multiplication problem.

One way to do this is by converting both decimals into fractions:

1.06 = 1 + 0.06 = 1 + 6/100 = 1 + 3/50 = 53/50

2.29 = 2 + 0.29 = 2 + 29/100 = 229/100

Multiplying these two fractions, we get:

\frac{53}{50} *\frac{229}{100} =\frac{12137}{5000}

Now, we can just convert this into a decimal by using a calculator:

12137/5000 = 2.4274, which is our answer.

Of course, you could just put the numbers in a calculator, which would be much less time-consuming.

Someone please pass the answers to this
arsen [322]

Answer/Step-by-step explanation:

1. The figure is composed of a triangle and a rectangle.

Area of the triangle = ½*base*height

base = 4 ft

height = 12 - 8 = 4ft

Area of triangle = ½*4*4 = 8 ft²

Area of rectangle = length * width

Length = 8 ft

Width = 4 ft

Area of rectangle = 8*4 = 32 ft²

✔️Area of the figure = 8 + 32 = 40 ft²

2. The figure is composed of a semicircle and a triangle

Area of the semicircle = ½(πr²)

radius (r) = 3 cm

π = 3

Area = ½(3*3²) = 13.5 cm²

Area of triangle = ½*base*height

base = 3*2 = 6 cm

height = 6 cm

Area = ½*6*6 = 6 cm²

✔️Area of the figure = 13.5 + 6 = 19.5 cm²
