Answer:
2.4x+15.2
Step-by-step explanation:
Amount of chemical A mixed in medicine = 9.357 g
Amount of chemical B mixed in medicine = 12.082 g
Amount of chemical C mixed in medicine = 7.502 g
We have to determine the total amount of medicine he prepared in grams.
Total amount of medicine
= 9.357 + 12.082 + 7.502
= 28.941 grams
So, he prepared 28.941 grams of medicine.
Now, we have to round each chemical to the nearest tenth.
Amount of chemical A mixed in medicine = 9.357 g
Rounding to nearest tenth = 9.4 grams
Amount of chemical B mixed in medicine = 12.082 g
Rounding to nearest tenth = 12.1 grams
Amount of chemical C mixed in medicine = 7.502 g
Rounding to nearest tenth = 7.5 grams
Answer:
111 grams
Step-by-step explanation:
fruit: yoghurt: total
2 : 3 : 2+3=5
The total mass is 185
Divide 185/5 = 37
Multiply each number by 37
fruit: yoghurt: total
2*37 : 3 *37 : 5*37
74 111 185
The mass of the yoghurt is 111
Answer=Carlos
If Jackie has 10 groups, with 3 in each groups, she has 30 total pennies.
10*3=30 pennies
If Carlos has 5 groups with 100 in each group, then Carlos has 500 pennies.
5*100=500 pennies
500 pennies is more than 30 pennies, so Carlos has more pennies
If this is an IXL there should be a calculator for the lesson. This will help with your answer, if it doesn’t I’m sorry I couldn’t help.
