The sides of a triangle are in the ratio of 3:5:9. The perimeter is 68 inches. how long is each side?

12 inches 20 inches 36 inches

Step-by-step explanation:

ratio of 3:5:9

Multiply each side by x

3x: 5x: 9x

Add the sides together to find the perimeter of 68

3x+5x+9x = 68

Combine like terms

17x = 68

Divide by 17

17x/17 = 68/17

x = 4

The sides lengths are

3*4: 5*4: 9*4

12 : 20: 36

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
