Pam drove her car 99 kilometers and used 9 liters of fuel. She wants to know how many kilometers (k) can she drive with 12 liters of fuel. How many kilometers can Pam drive with 12 liters of fuel ?

132 liters

Step-by-step explanation:

First divide 99 by 9 to see how much fuel she needs per kilometer

99/9=11 now multiply 11 by 12 to get  the amount of fuel she needs to drive 12 meters

12*11= 132 she needs 132 liters of fuel

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
