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:

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.
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
We have that
<span> 5x/7=22
multiply by 7 both sides
5x=22*7-------> 5x=154
divide by 5 both sides
x=154/5
x=30.8--------> x=30 4/5
the answer is
x=30 4/5</span>
