the answer should be 49mm
28*7 / 4 = 49
You can think of an hour and a half as 75% itself already because you have 3/4 or three thirty minute periods. So every 1/4 is a 30 minute period, and if you multiply 1/4 by 4 you get 4/4 which you ten can convert to 2 hours or 4, 30 minute time periods. (I’m sorry if I explained this in a very confusing manner). It will take Amelia 2 hours in total to finish her drawing.
Ashley sold 98 small cups and 57 large cups of lemonade.
Step-by-step explanation:
Given,
Price of small cup of lemonade = $1.25
Price of large cup of lemonade = $2.50
Total cups sold = 155
Total worth of cups = $265
Let,
x represent the number of small cups sold
y represent the number of large cups sold
According to given statement;
x+y=155 Eqn 1
1.25x+2.50y=265 Eqn 2
Multiplying Eqn 1 by 1.25
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 1.25
Putting y=57 in Eqn 1
Ashley sold 98 small cups and 57 large cups of lemonade.

Answer: See explanation
Step-by-step explanation:
Maria is incorrect as she didn't count the number of zeros properly. After knowing that 6 × 5 = 30, the question is 60×500 which means there are 3 zeros that should be added to the 30 that she got, this will have given her a value of 30,000 which is correct.
She write 3000 which is 3 under thousands rather than 30,000 which is 3 under tens of thousands.
