Answer:

52.5 cm^2

Step-by-step explanation:

The base length of the triangle on top is ...

8 cm - 1 cm - 2 cm = 5 cm

Then the area of that triangle is given by the formula ...

A = (1/2)bh = (1/2)(5 cm)(5 cm) = 12.5 cm^2

___

The area of the rectangle below that triangle is the product of its length and width:

A = (8 cm)(5 cm) = 40 cm^2

___

The total area is the sum of the areas of the rectangle and triangle, so is ...

total area = 40 cm^2 + 12.5 cm^2 = 52.5 cm^2

3. If ‘A’ can finish a work in ‘n’ days then part of work finished in 1 day is: (a) 1 – n

zaharov [31]

Answer:

If ‘A’ can finish a work in ‘n’ days then part of work finished in 1 day

will be $\frac{1}{n}$ .

Step-by-step explanation:

From the question, it is clear that

If ‘A’ can finish a work in ‘n’ days, then
we have to determine the part of work finished in 1 day.

let ' $n$ ' be the number of days $A$ takes to complete the whole work

Let the whole job be denoted as ' $1$ '

Thus, the part of work finished in 1 day will be:

$\:\frac{Total\:work}{Time\:taken\:by\:A\:to\:complete\:the\:work}\:=\frac{1}{n}$

Therefore, If ‘A’ can finish a work in ‘n’ days then part of work finished in 1 day will be $\frac{1}{n}$ .

What is the prime factorization of 200? 2 2 × 5 3 2 3 × 5 2 2 4 × 5 2 × 5 4

Misha Larkins [42]

Answer:

2^3 * 5^2

Step-by-step explanation:

We need to break 200 down into prime numbers

200 = 20*10 These are not prime

= 4*5 * 2*5 The 4 is not prime

= 2*2*5 * 2*5 This is prime

Rearranging

= 2*2*2*5*5

= 2^3 * 5^2
