Answer:
1.12675hours approximately
Step-by-step explanation:
If the tub was 4.97 gallons it would take 1 minute Right?
To find the the time required to fill the tub divide volume of tub by the rate of hose. We have 336/4.97=67.605minutes
Divide by 60` 67.605/60=1.12675hours approximately
Answer:
x = 4 or x = -13/4 = -4.33
Step-by-step explanation:
log (3x - 2) + log (x + 1) = 2 - log 2
Note 2 is also equals to log 100
log (3x - 2) + log (x + 1) = log 100 - log 2
log (3x - 2)(x + 1) = log (100/2)
log 3x² + 3x - 2x - 2 = log 50
log 3x² + x - 2 = log 50
3x² + x - 2 = 50
3x² + x - 2 - 50 = 0
3x² + x - 52 = 0
find the number to multiply that will give you -52 × 3 = -156 and add to give you 1. The numbers are -12 and 13.
3x² - 12x + 13x - 52 = 0
3x(x - 4) + 13( x - 4) = 0
(3x + 13)(x - 4) = 0
x = 4 or x = -13/4 = -4.33
If you insert 4 in the logarithm equation you will see that the left side is equal to the right
log (3x - 2) + log (x + 1) = log 100 - log 2
log 10 + log 5 = log 50
log 50 = log 50
Answer with explanation:
Let the length of rectangular fence = x meters
Let the width of the rectangular fence = y meters
Thus
Now Let the total cost to construct the fence be 'C' can be obtained if we construct the shorter side with material with cost $12 per foot
Using value of x from the equation i into equation ii we get
hence to minimize the cost we differentiate both sides with respect to 'y' and equate the result to zero thus we get
Thus
Thus value of length = 11.114 feet and value of width = 18.894 feet.
Answer: There are 6 phones and 18 accessories sold.
Step-by-step explanation:
Since we have given that
Let number of phones sold be 'x'
Let number of accessories sold be 'y'.
Commission for every phone = $12
Commission for every accessory = $3.50
Total commission = $135
And Difference between accessories and phones sold = 12
According to question, we get that
Using both the equations, we get that
x=6 and y = 18
Hence, there are 6 phones and 18 accessories sold.
