Where x is the percent discount,
x = 5/20 * 100.
The percent discount is 25%.
360 degrees in a circle
32/360 of total area is sector area
area=pir^2
r=8.5
area=pi8.5^2
area=226.980022 mm^2
multiply it by 32/360
sector=20.17600195555556
round
sector=20.2
C is answer
Answer:8 cm by 10 cm
Step-by-step explanation:
8*2+10*2=36
8*10=80
Answer:
1/5
Step-by-step explanation:
You expect to get 12 red marbles out of 60 trials.
So, you expect to get a red marbles 12/60 of the times.
We can simplify that 12/60 to 1/5, which is a choice of answers. :-)
We assume here you correctly assume your probability level when you did your forecast of 12/60. And either you're picking from a small pool and re-insert the marble, or you have a very large amount of marbles (at least 60).
Answer:
x^2+2x
Step-by-step explanation: You would take x and multiply it by x and get X^2 then you would take x anm multiply it by 2 to get 2x. It is distributing
