Answer:
There is a 3/20 chance that a red plastic marble will be taken out on random.
Step-by-step explanation:
This is because there are 14 yellow marbles, and 6 red marbles. Along with this, half of the red marbles are made out of plastic. This leaves 3/6 of the red marbles made out of plastic. When combined with the yellow marbles, you'll add 14 to the denominator, since there are 14 yellow marbles. (Red + Yellow = Total Number Of Marbles) This leads to a total count of 3 marbles of the 20 total marbles, being red and made out of plastic.
To get the answer we can use proportion. We know that 350 its 100% and 378 its 100% + taxes.
350% ------------ 100
378% ------------ x
cross multiply now
350*x=378*100
350x=37800 /:350
x=108
Now we see that taxes its 8%, because final price its 100% + taxes = 108%
Answer:
length of an arc = θ/360 × 2πr
θ=116°
r=2
π= 3.14
l= 116/360 ×2×3.14×2
l= 4.047= 4.05cm
