Answer:
A
Step-by-step explanation:
Answer:
find the current mean(average), then add 10, last divide by 1.3
Step-by-step explanation:
Answer: a=2/5b + 1/5c (I may have answered your question but idk if I did)
Step 1: Add -4a to both sides.
9a−2b+−4a=4a+c+−4a
5a−2b=c
Step 2: Add 2b to both sides.
5a−2b+2b=c+2b
5a=2b+c
Step 3: Divide both sides by 5.
5a/5=2b+c/5
a=2/5b+1/5c
Answer:
7,854 cm
Step-by-step explanation:
The area of a circle is given by πr², and the radius is the diameter/2:
100/2=50
π•50²=7,853.98≈7,854
Let me explain it like this. add an extra 0 after 10 and you have 100 so every time you add 10 to the original number you are adding 100% so your answer would be 140%
