Find the missing length. Round to the nearest tenth, if necessary.

The missing length is: 19.4

Step-by-step explanation:

according to pythagorean theorem, a^2 + b^2 = c^2

the hypotenuse is 21 and side and the short leg is 8

c²-b²=a²

21²-8²

441-64

377

take the square root of 377

it is 19.41

which rounds to 19.4

x=19.4

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
