A pendulum is L meters long. The time, t, in seconds that it takes to swing back and forth once is given by t=2-/L. Suppose the pendulum takes  6.02 seconds to swing back and forth once. What is its length? Carry your intermediate computations to at least four decimal places, and round your answer to the nearest tenth.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.
