Track A takes 20 minutes
Track B takes 15 minutes
In 1 minute track be will do a fraction of 1/20, while track B will do 1/15
Both tracks in a minute = 1/20+1/15
= 35/300
Therefore the two tracks will take 300/35 minutes to fill the 200 cubic feet
That is 300/35
= 8.57 minutes
≈ 9 minutes
Answer:
Step-by-step explanation:
For the function to have a domain of all reals, the denominator cannot have a value of zero. x^2 + 2cx + 14 will not have zero as a root if it has no real solutions. A quadratic equation has no solutions when the discriminant is negative.
b^2 - 4ac < 0
(2c)^2 - 4(1)(14) < 0
4c^2 - 56 < 0
4c^2 < 56
c^2 < 14
Y=6x
The slope of the equation is six meaning you go up six and over 1 to find the next point.
.18 * 27.32 = 4.9176
18% of 27.32 = 4.91
4.91 + 27.32 = 32.23
If Michael and Imani add an 18% tip to 27.32, their lunch cost will be $32.23 in total.
Hope this helps you! (:
