Archer made a tunnel for his hamster out of two cardboard tubes. One tube was 8\dfrac{5}{8}\text{ in}8 8 5 ​ in8, start fraction, 5, divided by, 8, end fraction, start text, space, i, n, end text long. The other tube was 7\dfrac6{8}\text{ in}7 8 6 ​ in7, start fraction, 6, divided by, 8, end fraction, start text, space, i, n, end text long. What is the total length of the tunnel?

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
