Ineed ! suppose you want to make a triangular rack to go along with your new pool table. the rack will be an equilateral triangle with sides that are 38 cm long. if you have 120 centimeters of wood already, would you need to buy more wood before beginning the project? explain your answer

If the rack is an equilateral triangle, then its three sides are all the times. Therefore, you need three pieces of wood 38 cm long to make the rack. You can find the total amount by multiplying 38 times 3, which will be 114 cm. So, you don't need to buy more wood because the 120 cm you have is enough.  

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
