11 skirts since you can use 3/4 on each yard of 9. Then you get a remander of 2, 3/4! 9 + 2 is 11.

Answer:

Durability

Step-by-step explanation:

Durability in money is when objects used as money can withstand being worn out or torn. In this case, the bill is still used though it has a tear therefore it's an example of durability.

Answer:

264 miles

Step-by-step explanation:

Let's convert 3 hours and 40 minutes into hours first.

Recall that 1 hour = 60 minutes.

Therefore 40 minutes = 40/60 hours = 2/3 hours.

The car travelled 3 and 2/3 hours in total.

Recall that distance = speed times time.

The car has travelled 72 x 3 2/3 miles = 264 miles.

$\text{Hello there!}\\\\\text{Use the Pythagorean theorem first:}\\\\a^2+b^2=c^2\\\\\text{Plug 70 to c since it's your hypotenuse and plug 40 to a}\\\\40^2+b^2=70^2\\\\\text{Solve for b:}\\\\40^2+b^2=70^2\\\\1600+b^2=4900\\\\\text{Subtract 1600 from both sides}\\\\b^2=3300\\\\\text{Square root}\\\\b=57.4456\\\\\text{Round to the nearest tenth}\\\\57.4\\\\\text{Add 10 to 55.4 because the ladder is 10 ft off the ground}\\\\67.4\\\\\boxed{\text{Answer: about 67.4 ft}}$
