Answer:
There are 101 marbles in each bag and 10 marbles left over
Step-by-step explanation:
We can use the modulus to find out left over. The modulus is the remainder of the division from one number by another number. For example, 7 % 2 = 1. When you divide 7 by 2, division is 3 but the remainder is 1.
1525 % 15 = 10 marbles are left over
Now, we know that 1525 - 10 = 1515 marbles are equally put into each bag. That means each bag contains
1515 / 15 = 101 marbles
Answer:
8 minutes
Step-by-step explanation:
Speed or Rate = Distance / time
Distance = Speed × time
Nicholas's sand castle is 30 cm tall and he is adding sand at a rate of 12 cm per minute.
Nicholas = Nina
30cm + (12cm/min)x
= 30 + 12x
Nina's sand castle is 78 cm tall and she is adding more sand to it at a rate of 6 cm per minute.
78cm + (6cm/min)x
78 + 6x
30 + 12x = 78 + 6x
12x - 6x = 78 - 30
6x = 48
x = 48/6
x = 8 minutes
Therefore, after 8 minutes, Nina and Nicholas's sand castles be the same height.
