Circumference= diameter x pi
12x3.14 = 37.68
Answer:
x = 62.3 degrees.
Step-by-step explanation:
We should notice a certain trigonometric function that works here.
tan x = opposite side / adjacent side
tan x = 40/ 21
x = arctan (40/21) = 62.3005 degrees
x = 62.3 degrees.
Answer:
- b
- f
- e
- c
- h
- d
- g
- a
Step-by-step explanation:
< or > will give you an open dot which means it is not filled in.
≤ or ≥ will give you a closed dot which means it is filled in.
So for example number one:
x > 0 translated is x is greater than zero.
So look on the number line for an open dot on zero going toward the left (the side where the numbers get smaller). The rest are self explanatory.
Answer:
x = 4.5
Step-by-step explanation:
there's definitely other ways to solve this, but I used a proportion.
Then you can make this equation:
14x = 3.5 * 18
I solved for it and got 4.5 .
