Answer:

Salt water is more dense than freshwater.

Step-by-step explanation:

A boat is always able to float on water because it experiences an upthrust upwards.

The magnitude of the upthrust depends upon the density of the liquid.

When the liquid is denser the boat will experience a high upthrust as compared to when in a less dense liquid.

Now, ocean water consists of salt which makes it more dense, thus If the boat sinks lower into the water in a freshwater lake than in ocean, then Salt water is more dense than freshwater.

Answer:

Ocean water has more salt than freshwater. More salt causes you to float. For example, the Dead Sea is so salty that it is nearly impossible to swim, you always float while you're in it due to all the salt.

Lakeview is 101 miles from Springfield. Irania must go to the law library in Springfield to get a document for the law firm for

Arlecino [84]

Answer: Approximately 4.1224 hours

4.1224 hours = 4 hours, 7 minutes, 21 seconds approximately

===========================================

Work Shown:

d = distance = 2*101 = 202 miles

r = rate or speed = 49 mph

t = time = unknown

d = r*t

202 = 49*t

49t = 202

t = 202/49

t = 4.1224 hours approximately

--------------

If you want to convert to hours,minutes,seconds, then...

4.1224 hours = 4 hours + 0.1224 hours

4.1224 hours = 4 hours + (0.1224*60) min

4.1224 hours = 4 hours + 7.344 min

4.1224 hours = 4 hours + 7 min + 0.344 min

4.1224 hours = 4 hours + 7 min + (0.344*60) sec

4.1224 hours = 4 hours + 7 min + 20.64 sec

4.1224 hours = 4 hours + 7 min + 21 sec ..... approximate

4.1224 hours = 4 hours, 7 min, 21 sec .... also approximate

Note: this time value is driving time only. It does not take into account any time spent at the law library or any other stops.

Does the table represent y as a function of x? Justify your answer.

Otrada [13]

Answer:

Step-by-step explanation:

As per definition of the function, every x- value (input) has exactly one corresponding y-value (output)

We can see on the table:

x = 3.45 and y= 1.72
x = 3.45 and y = 3.36

Two same input values with different outputs.

So this not a function

1 Javier has at most $15.00 to spend today. He buys a bag of pretzels and a bottle of juice for $2.59. If gasoline at this store

Art [367]

Answer:

Javier can buy at maximum about 3.7 gallons of oil.

Step-by-step explanation:

Let g represent the amount of gasoline in galloons.

We know that Javier has at most $15.00 to spend. In other words, the total cost after buying the snacks and gasoline must be less than or equal to 15.

He already bought a snack and a drink for a total of $2.59.

And each gallon of gasoline costs $3.39.

So, we can write the following inequality:

$2.59+3.39g\leq 15.00$
