Answer:
<u>3 stamps were left over</u>
Step-by-step explanation:
<u>Division</u>
When a number m divides evenly by n the remainder is 0. For example, 120 divides exactly by 30 because 120/30=4 and the remainder is 0.
But 120 does not divide exactly by 50 because 120/50 = 2 and leaves a remainder of 20.
Jeff divided his 1,200 stamps equally among 7 stamp albums. If the division of 1,200 by 7 was exact, there won't be any stamp left over. Let's test it.
1,200/7 is 171.4, obviously is not exact, thus There were stamps left over.
How many?
Multiply the lower integer of division 171 by 7 to get: 171*7 =1,197. This means that 1,200-1,197= 3 stamps were left over
Multiply both sides by -1
|-x|=12
-x=12
x=-12
-x=-12
x=12
Final answer: D
Rachel should perform better because of the spacing effect.
Given,
Rachel will study one hour each day for 5 days and Jennifer will study 5 hours the day before the exam.
What do you predict about their scores?
Rachel should perform better because of the spacing effect.
The spacing effect demonstrates that learning is more effective when study sessions are spaced out. This effect shows that more information is encoded into long-term memory by spaced study sessions, also known as spaced repetition or spaced presentation, than by massed presentation.
