La salinidad del océano se refiere a la cantidad de material disuelto encontrado en una muestra de agua de mar. La salinidad S se puede estimar a partir de la cantidad C de cloruro en agua de mar usando S=0.03+1.805C, donde S y C son medidos por peso en partes por mil. Aproxime C si S es 0.35.

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

the anwser is d) 75°

step-by-step explanation:

3

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.

sorry if it was confusing!

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
