Answer:

Total surface area = 184.86 cm²

Step-by-step explanation:

If we see the the diagram, we can find that the net of this triangular prism includes:

2 triangles each with the dimension of one side 4.3cm, second side 5.2cm and third side 6.75 cm

3 rectangles each with the dimensions of (6.75×10)cm, (5.2×10)cm and (4.3×10)cm

Surface area of triangle with a,b and c side:

s=(a+b+c)/2

Area= √s(s−a)(s−b)(s−c)

Area = 11.18cm²

For 2 triangle:

Area = 22.36cm²

Surface Area of Rectangles:

Area = (6.75×10)cm + (5.2×10)cm + (4.3×10)cm

Area = 162.5 cm²

Total surface area = area of 2 triangle + area of 3 rectangles:

Total surface area = 22.36 + 162.5

Total surface area = 184.86 cm²

adelina 88 [10]
Addition is defined as one of the main basic operation of mathematics. Addition is also defined as the process of adding one of more numbers. For the addition operation, there are many number of properties used. In that, one of the property is known as the commutative property of addition. It states that the change of order does not change the value of addition. Commutative property of addition is true for all types of numbers including imaginary numbers. So you can pretty much use any numbers ex.2 + 3 = 3 + 2

the annual rate of inflation is given by the formula I = (p2/p1)^1/n - 1, where p1 is the initial price of an item and p2 is the
aleksklad [387]

Answer:

<h2>The value of n is 31 years.</h2>

Step-by-step explanation:

The given equation is formed by different variables, where n indicates the period of time in years where the rate of inflation is calculated.

In this case, we have a period from 1980 to 2011. The difference between these years would be the period of time used to find the inflation rate.

2011-1980=31

Therefore, the value of n is 31 years.
