At its highest salinity, the water in utah’s great salt lake contains about 14.5g of salt in 50g of lake after. what was the salinity of the lake?

  29% . . . or . . . 290‰

Step-by-step explanation:

The ratio of weight of salt to weight of water was ...

  (14.5 g)/(50 g) = 29/100 = 29%

Sometimes, salinity is expressed as "parts per thousand".

  29/100 = 290/1000 = 290‰

Use of the abbreviation "PPT" for "parts per thousand" is not recommended, as that abbreviation has several different interpretations, including "parts per trillion."

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
