Just add up the 3 legs of the triangle representing J's walk.

From (2,9) to (7,9) is 5 miles; from (7,9) to (2,2) is sqrt(25+49) miles (using the Pythagorean Theorem); and from (2,2) to (2,9) is 7 miles.

Add these 3 lengths together to obtain your final answer.

A train leaves in Zurich at 22 40 and arrives in Vienna 07 32 the next day Work out the Time train takes
myrzilka [38]

Answer:

The train takes 8 hours and 52 minutes.

Step-by-step explanation:

Both Zurich and Vienna are in the same time zone, so there is no time to adjust the time zone.

Leaves: 22:40

Arrives: 7:32

From 23 to 7:32 there are (7 - 0) + (24 - 23) = 8 hours.

32 + (60 - 40) = 32 + 20 = 52 minutes.

The train takes 8 hours and 52 minutes.

The perimeter p of the rectangle equals 30. Find the value of X?
Ilia_Sergeevich [38]

Answer:

13

Step-by-step explanation:

The perimeter is calculated by multiplying the sum of width and height with 2

2*(4x-2+7x+9) = 300 solve inside the parenthesis

2*(11x+7) = 300 multiply inside the parenthesis with 2

22x + 14 = 300 subtract 14 from both sides

22x = 286 divide both sides by 22

x = 13
