Answer:
i think 88
Step-by-step explanation:
(it's been a while since I've done this so I'm not too sure it's correct)
The formula we need to use is
2πr(angle/360)
we need the radius (r)
To get r we need angle AES
180-80= 100
using the equation from before
88=2πr*(100/360)
raidus: 50.42
Then to get the length CD we need angle DEC
180-80=100
2π*50.42*(100/360)=88
there probably was some kind of shortcut we could've used to figure this out faster but whatever
Answer:
$124,400
Step-by-step explanation:
The scholarship pays for 30% of her tuition. This leaves her responsible for 100-30 = 70% of it. 70% = 70/100 = 0.7; this makes her part of the yearly tuition
0.7(29500) = 20650
She is still responsible for her $9600 room and board per year. Her books are paid for by the scholarship; however she still has the lab and facility fees at $850 per year.
Altogether this gives her a total of
20650+9600+850 = 31100 per year. Over the course of 4 years, this will cost her
31100(4) = 124400
Answer:
The number of pink pens can be 19 .
Step-by-step explanation:
Total Number of pens = 20
Let x be the number of pink pens
We are supposed to find If the probability of choosing a pink pen is close to 1, how many pink pens would you expect to see in Amanda's bag
Probability of choosing a pink pen = 
Probability of choosing a pink pen =
ATQ
≈1
x≈20
So, the number of pink pens can be 19 .
Well, you must first do your equation k=y/x so k= 18/4 or 9/2
now you use the equation y= kx or y= 9/2 times 24... 9/2 times 24 is 108 so y=108
