Ying eats some yoghurt. The yoghurt contains 192 mg of calcium. This is 16% of the total amount of calcium that Ying should have each day. Work out the total amount of calcium that Ying should have each day, showing your working out (3 marks).

1200 mg

Step-by-step explanation:

192 mg : 16%

X : 100%

192/16 = X/100

X = 192/16 × 100

X = 1200 mg

the answer is 4.8 units on e2020.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
