To get a close estimate, we can round 49 up to 50 and 311 down to 300, obtaining an estimate of 50/300 = 1/6, or 0.1666... as a repeating decimal. That decimal approximation is a little less than one hundredth away from the actual decimal approximation of ≈ 0.1576
Answer:
80 is 50% of 160.
Step-by-step explanation:
In order to find this, we take the whole number and divide by the percentage that it represents. This gives us the number we are looking for.
80/50%
80/.50
160
Find the greatest common factor (GCF)
in this case it would be 9
divide each term by the GCF
36 / 9 = 4
9y / 9 = y
put the two "new" terms in parenthesis and the GCF in front of it
9 (4 + y)
it could also be 9 (y + 4) because of Commutative Property of Addition
Step-by-step explanation:
Things I notice about this problem:
- "Difference" indicates subtraction.
- When a problem simply says "a number," I replace it with a variable.
It is written out like this:
.
Answer:
D is eliminated as it goes down to 4, if counted by 1. The answer is B. y= 1/2x² – 4
