The probability of it showing a 1 is 1/6 and the probability of it showing an even number on the second roll is 3/6.
<span>1. </span><span>So in every 1 hour, there’s 281
gallons go through in a certain valve.
Now, let’s find the total number of gallons that will go through in 91 hours.
Let’s assign a variable for the value of total number of gallons.
Let x be the value of number of gallons
x = number of gallons in 91 hours
=> 281 gallons/ hr
=> 281 x 91
=> 25 571 gallons / 91 hours
Thus, x = 25 571 gallons will go through the open valve in 91 hours,

Answer:
480 km/h
Step-by-step explanation:
80 x 6 = 8 x 6 x 10
48 x 10 = 480
Beth can make 8 steps. If you take 21 and divide it by 2.5 you get 8.4 but she can’t make a 4th of a step so just round it down to 8.
The principal value is $150.
We have the following values -
rate of interest - 4%
Time period = 6 months = 0.5 year
Simple interest = $36
We have to find the principal value.
<h3>What is the formula to calculate the Simple Interest for a Principal amount of $P at a rate of r% per annum for time of t years?</h3>
The simple interest can be calculated using the formula -
S.I. = ![\frac{P\times r\times t}{100} \\](https://tex.z-dn.net/?f=%5Cfrac%7BP%5Ctimes%20r%5Ctimes%20t%7D%7B100%7D%20%5C%5C)
The above expression can be written in terms of principal value as -
![P = \frac{100\times S.I.}{r\times t}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B100%5Ctimes%20S.I.%7D%7Br%5Ctimes%20t%7D)
We can use the above formula in the question given - Using the formula for principal value we get -
P = ![\frac{100 \times36}{4\times 0.5}](https://tex.z-dn.net/?f=%5Cfrac%7B100%20%5Ctimes36%7D%7B4%5Ctimes%200.5%7D)
P = ![\frac{3600}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3600%7D%7B2%7D)
P = $1800
Hence, the principal value is $150.
