First, find the amount of time is taken to travel 1 mile :
time taken to travel 1 mile = 20/6 = 3 ⅓ mins
hence, time taken to travel 9 miles = 3 ⅓ x 9 = 30 mins

time taken to travel 10 miles = 3 ⅓ x 10 = 33 ⅓ mins

Answer:

1. 30 minutes to walk 9 miles.

2. 33.33 minutes to walk 10 miles.

Step-by-step explanation:

I divided 20 by 6, and got 3.33. If you multiply 3.33 by 9 you get 30, and if you multiply 3.33 by 10 you get 33.33.

The sum of a number and its reciprocal is 13/6. find the number

iris [78.8K]

Suppose the number is x, its reciprocal is 1/x
x+1/x=13/6
(x^2+1)/x=13/6
6(x^2+1)=13x
6x^2-13x+6=0
(3x-2)(2x-3)=0
x=2/3 or x=3/2

Simplify the expression <br> y^12/y^12

andreev551 [17]

Step-by-step explanation:

________________________________

Step 1:

$\frac{{y}^{12} }{ {y}^{12} }$

Wright the equation

________________________________

Step 2:

${y}^{12 - 12}$

Transfer the power of y ie ¹² up to subtract it

________________________________

Step 3:

${y}^{0}$

by subtracting the powers we get 0

________________________________

Step 4:

$1$

so the results comes 1 because anything ⁰=1

Find the z score that cuts-off the largest 9% under the standard normal curve. a) -1.34 b) 1.34 c) 0.536 d) 1.28

topjm [15]

Answer:

b) 1.34

Step-by-step explanation:

The z score is used to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the z score is above the mean while for a negative z score implies that it is below the mean. The z score is given by:

$z=\frac{x-\mu}{\sigma}$

For the largest 9%, the score is 100% - 9% = 91% = 0.91

From the normal distribution table, the z score that corresponds to 0.91 is 1.34
