Answer:
Red balls = 84 Blue balls = 140
Step-by-step explanation:
Ok so there are 225 marbles
And ratio here is Red : Blue = 3 : 5
So Red marbles = 3x whereas Blue marbles = 5x
Therefore,
3x + 5x = 225
8x = 225
x = 28.125 = 28
<u>Red balls = 28*3 = 84 Blue balls = 28*5 = 140</u>
(Pls check whether total no of balls is 224)
Total number of Marbles is = 5 + 8 + 7 = 20
Total number of non-red marbles = 5 + 7 = 12.
P( Not yellow) 12/20 = 3/5.
<h3>The answer is 3/5.</h3>
Answer:
282 hr <======= see below
Step-by-step explanation:
Distance / rate = time
2.4 x 10^9 mi / 85 m/hr = 28235294 hr
You must have left the power of 10 off of your speed
probably should be 8.5 x 10^6 perhaps? then answer is 282
<h3>If speed was 8.5 x 10^5
then answer becomes ~ 2820 </h3>

Step-by-step explanation:
Answer:Magnitude of voltage is 41.9963 volts
Step-by-step explanation:
Given that current I =5.772-5.323i mA
and impedance, Z=3.342+4.176i kilo ohms
Then voltage in the circuit = IZ
![=(5.772-5.323i)X10^{-3}X(3.342+4.176i)X10^{3}](https://tex.z-dn.net/?f=%3D%285.772-5.323i%29X10%5E%7B-3%7DX%283.342%2B4.176i%29X10%5E%7B3%7D)
![V=(5.772-5.323i)X(3.342+4.176i)](https://tex.z-dn.net/?f=V%3D%285.772-5.323i%29X%283.342%2B4.176i%29)
