Answer: B, 5.5
Step-by-step explanation:
4+4+4+5+5+6+6+6+6+9=55
55/10=5.5
A percentage can just be written as a decimal where 100% = 1.00
15% = 0.15
75.5 * 0.15 = 11.325
You just multiply.
Since opposite angles of a cyclic quadrilateral are supplementary,
A= 180-101=79°
B= 180-68=112°
When you have factors in shapes you must remember:
circumference and perimeter are in one unit measures
area is in squared units
volume is in cubed units
So, when the circumference of A is 4 times that of C there is a factor of 4.
Since we need to know the area the factor 4 will change to a factor of 4² since area is a squared unit.
The solution is 4²=16, the are of circle A is sixteen times the area of circle B.
Answer: -3/10
Step-by-step explanation: A positive and a negative will subtract.
1. Find the common denominator (8/10)
2. simce 8/10 is greater than 1/2 you need to add a negative to get 8/10 a lower value
3. subtract 5/10 or 1/2 from 8/10 to figure out what gives you the correct answer
