Nos jogos olimpicos de verao ,o triatlo e composto de 1500 m de nataçao, 40.000 m de ciclismo e 10.000 m de corrida em certa competiçao de triatlo, os atletas devem nadar um vinte e cinco avos (fraçao) do percurso, correr um quinto (fraçao) e pedalar o restante a- que fraçao do percurso um atleta deve percorrer sem bicicleta? b- que fraçao do percurso o atleta percorre com a bicicleta? c- sabendo que nessa competiçao o percurso total é de 7500 m, quantos metros correspondem a cada um das etapas?

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.

step-by-step explanation:

6e14 is the answer.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
