12. 8 Kg 8g = Kg (in decimal form)
13. Convert 5/4 into decimals
14. A cone has face/faces
15. 4.5 cm is equal to cm and mm
16. How many right angles do you make if you start facing south and turn to north?

Answer 1

Step-by-step explanation:

11.

$product \: of \: mean = product \: of \: extreme \\ 9 \times 25 = 15x \\ 15x = 225 \\ x =15$

12.

$1g = \frac{1}{1000} kg \\ 8kg \: 8g= 8 \times 8 \times \frac{1}{1000} kg \\ = \frac{64}{1000} kg \\ = 0.064kg$

13.

$\frac{5}{4} = \frac{5 \times 25}{4 \times 25} \\ = \frac{125}{100} \\ = 1.25$

13. Cone has 2 faces curved surface and a base
