Answer:
-12.8%
Step-by-step explanation:
To calculate the percent decrease, we:
- Find the difference between the new value and the original
- Divide the number by the original
- Multiply by 100 and the % symbol.
The population of the town originally had 25,000. 3,200 people moved away. This means that the new population is 21,800.
- 21,800-25,000=-3,200
- -3,200/25,000=-0.128
- -0.128(100)=-12.8%
The towns population decreased by 12.8%.
Yes, C is lower than 4.
Explanation: If we think of
C as 2 and
S as 2
then we can apply multiplication (cs=c multiplied by s) and get 4. So, S and C cannot be any bigger than 2.
The triangle that must appear to be obtuse mmust have one of its angle to be greater than 90 but less than 180 degrees:
<h3>What are obtuse triangles?</h3>
Obtuse triangles are triangles that has one of theor angles to greater than 90 degrees.
Most obtuse triangles has two acute angles (angles less than 90 degrees) and a obtuse angle (angles between 90 and 180 degrees)
Hence the triangle that must appear to be obtuse mmust have one of its angle to be greater than 90 but less than 180 degrees:
