Answer: 0.122449
Step-by-step explanation:
If one side is 1/7, first convert that into a decimal, which is 0.14286. Than square that 0.14286 x 0.14286= 0.020408. That’s the area of one square. Now multiply that by 6 (the number of sides in a cube) and you get 0.122449.
Answer:
The solutions are
Step-by-step explanation:
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
square root both sides
Answer:
1 hour 20 minutes
Step-by-step explanation:
Time to fix car ( repair time ) = 20 minutes
Breakdown rate ( λ ) = 2 car per hour
<u>first step : determine service the service rate ( μ )</u>
= 60 minutes / 20 minutes
= 3 cars per hour
<u>next : determine the average waiting time for a disabled car </u>
= 1 / (μ - λ)
= 1 / service rate - breakdown rate
= 1 / ( 3 - 2 )
= 1 / 1 = 1 hour
Finally Total time for a disabled car to be fixed
= repair time + average waiting time
= 20 minutes + 60 minutes
= 1 hour 20 minutes
Answer:
Ok so im not the best at explaining but its worth a shot
C)25
Step-by-step explanation:
we already know that the formula to find area is
A=l*w
and that every square is 1 square unit.
So in the first part on the far left, you count down 8 and over 2 to find how many total squares are shaded. This is the length and width of that one part so you multiply 8*2 to get 16.
In the next part, you should count starting at -1 over to 5 to get 6. It only has a width of 1 so 6*1 is still 6.
In the last part you start counting at -3 and count down to -6 and this gives you 3. It is 1 unit wide so 3*1 is 3.
Add 16+6+3 together because that is the combined area of the 3 parts and we get 25
Like i said im definitely, by no means, the best at explaining but if this helped even a little that's awesome, if you have any particular questions i can try to answer them in the comments
The answer is 4 because first numbers in orderes pair is always x cordinate
