Respuesta :
đổi 40ml = 0,04l
150ml = 0,15l
số nước mà silvia đã dùng là:
0,04 + 0,15 = 0,19 (l)
tổng số nước còn lại trong bình tưới là:
3,48 - 0,19 = 3,29 (l)
vậy tổng số nước còn lại trong bình tưới là 3,29 lít nước
The total amount of water remaining in the watering can of Silvia after watering the cactus and rose plant is 3.29 litres
How to form mathematical expression from the given description?
You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to decrease some item by 4 , then you can subtract 4 from that item to decrease it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
How many millilitres are there in one litre?
1 litre contains 1000 millilitres.
Given that:
- Water in watering can initially = 3.48 litres
- Water given to cactus plant = 40 millilitres
- Water given to rose plant = 150 millilitres
3.48 litre = [tex]3.48 * 1000 = 3480[/tex] millilitres
Total water given to plants = 40+150 = 190 millilitres
Remaining water in water can = water it initially had - water given to plants = 3480 - 190 = 3290 millilitres
Converting this back to litre:
1000 millilitre = 1 litre
1 millilitre = 1/1000 litres = 0.001 litres
3290 millilitres = [tex]3290 \times 0.001 = 3.29 \: \rm litres[/tex]
Thus, the total amount of water remaining in the watering can of Silvia after watering the cactus and rose plant is 3.29 litres
