The answer is the last one
Answer:
78.5 cm
Step-by-step explanation:
The area of a circle is represented by A = πr². Since we are replacing the value of pi(π) with 3.14, and the diameter is 10, meaning the radius(r) is 5, we can plug both values into the equation, to get A = 3.14(5^2). This simplifies to 78.5.
3/5=0.6
4/8=0.5
5/?=0.4
6/?=0.3
5/0.4=12.5 f(5)=12.5
6/0.3=20 f(6)=20
Answer:
x=-47
Step-by-step explanation:
3(5x+4)=7(2x-5)
15x+12=14x-35
x+12=-35
x=-47
Angles 6 and 7 are vertical angles, not alternate interior.
The same applies to angles 4 and 1, and angles 5 and 8 as well.
Any time you have two lines cross to form an X shape, the angles that are opposite one another are considered vertical angles and are always congruent.
The values you have typed into the boxes are all correct. The other drop-down choices are correct as well. Nice work.
