Answer:
A 3/30=x/12
Step-by-step explanation:
According to the recipe,
For 2 batches, 3 cups of flour required.
One batch has 15 mix rolls
Then 2 batches will have 2 (15) = 30 rolls

Answer:
Troy drinks 1,800 litres of water each day
Step-by-step explanation:
The question is simply asking us to convert and unify the units between litres (L) and millilitres (mL).
amount of water drank = 1.8 L
1 litre = 1000 millilitre
1 L = 1000 mL
∴ 1.8 L = 1.8 × 1000 = 1,800
∴ Troy drinks 1,800 litres of water each day
Answer:
1 495 500 505 500
2 525 515 505 515
3 470 480 460 470
Step-by-step explanation:
Suppose to be sample are
- 495 500 505 500
- 525 515 505 515
- 470 480 460 470
In the given sample if sample 3 is difficult to control .Because engineer wants to construct a sample mean controlling the service to his company produces.In sample set first two sets have continuous four headlamps but in third it is difficult to handle the control.
