Michael estimated his mass as 8 kilograms. Is his estimate reasonable? Justify your answer.
Gennadij [26K]

Answer:  The answer is Yes.


Step-by-step explanation:  Given that Michael estimated his mass and found it to be 8 kilograms. It may sound awkward to us, but its true. Because when we measure our weight by the weight machine it gives us the product of our actual mass and the acceleration due to gravity.

From second law of motion, we have

Weight = mass × acceleration due to gravity.

That is, W = m × 9.8 m/sec².

The unit of mass is kilogram and 1 kg m/sec² = 1 Newton. Therefore, the unit of the weight we generally measure is Newton (N), not kilogram. Here is what we make mistake usually.

Thus, if Michael' mass is 8 kg, then his weight will be

W = 8 × 9.8 kg m/sec² = 78.4 N, which is normal weight of a person.

Thus, his estimation is perfectly OK.

gross income £12000 tax free allowance £6475 what is taxable amount @20%, tax payable,net income and weekly net amount how to wo
olganol [36]
We calculate for the taxable income by subtracting the tax free allowance from the gross income.

          Taxable income = Gross income - tax free allowanc
           Taxable income = (£12,000 - <span>£6,475)
                                    = </span><span>£5,525

Hence, the taxable income is equal to </span><span>£5,525.

Net income: 
This would be equal to the gross income minus the amount of taxes to be paid.
 
                 Net income = Gross income - amount of tax to be paid
                 Net income = (</span><span>£12,000) - (0.20)($5,525)
                 Net income = $10,895

Therefore,

Find the area of the shaded region. Use 3.14 for pi.
daser333 [38]

Answer:

326

Step-by-step explanation:

First you find the area of the triangles. Since squares have equal sides we know that the triangle has a side of 20 and 12. We plug this information into the formula A=20x12/2 which equal 120 but since we have 2 triangles we multiply by 2 and get 240. Then we find the area of the square which is 400 when you multiply 20x20. Then you find the area of the circle which is 3.14x10^2 which equals 314. You add 240 and 400 to get 640. You subtract 460 from 314 and get 326.
