hope this help ma

3x + 2y = 14
3x = 14 - 2y
3x = 12y

A volcano on a recently discovered planet rises to a height of .
Use the table of facts to find the height of 15.338 mi. the volcano in feet.
Round your answer to the nearest tenth.

12 inches ( in ) = 1 foot ( ft )
3 feet ( ft ) = 1 yard ( yd )
36 inches ( in ) = 1 yard ( yd )
5280 feet ( ft ) = 1 mile ( mi )
1760 yards ( yd ) = 1 mile ( mi )

Answers

Answer:

21 km

Step-by-step explanation:

The volcano has a height of over 21 km (13.6 mi or 72,000 ft) as measured by the Mars Orbiter Laser Altimeter (MOLA). Olympus Mons is about two and a half times Mount Everest's height above sea level.

Unit conversion is the conversion of one unit to another unit with its standard conversion.

The height of the volcano is 15.338 miles.

1 mile = 5280 feet.

15.338 miles = 80984.6 feet.

The height of the volcano in feet is 80984.6 feet.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 meter = 100 cm

We have,

The height of the volcano = 15.338 miles ___(1)

It is given that,

1 mile = 5280 feet _____(2)

From (1) and (2) we get,

15.338 miles

= 15.338 x 1 mile

= 15.338 x 5280 feet

= 80984.64 feet

Rounding to the nearest tenth.

= 80984.6 feet

Thus,

The height of the volcano is 15.338 miles.

1 mile = 5280 feet.

15.338 miles = 80984.6 feet.

The height of the volcano in feet is 80984.6 feet.

Groundhog's Day is on February 2nd each year. On this day, in Punxsatawney, Pennsylvania, thousands of onlookers watch to see if Phil, the groundhog, will cast a shadow. If he does, then six more weeks of winter are predicted. If he doesn't, then an early spring is predicted. Historically, Phil's prediction has only been correct about 40% of the time.

Using complete sentences, design a simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years. Make sure to explain how you would use the simulation to determine the probability.

Answers

A simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years is given as follows:

Choose three numbers with replacement from the set of 0 to 9, which:

numbers from 0 to 3 representing that Phil is correct.numbers from 4 to 9 represents that Phil is incorrect.

How to calculate a probability?

The parameters that are needed to calculate a probability are given as follows:

Number of desired outcomes in the context of a problem/experiment.Number of total outcomes in the context of a problem/experiment.

Then the probability is calculated as the division of the number of desired outcomes by the number of total outcomes.

The probability of a success on a single trial is given as follows:

40% = 0.4, as Phil is correct 40% of the time.

Hence the simulation needs to have three trials, each with a 0.4 = 40% probability of a success.

Answers

Answer:

do you still need help?

Step-by-step explanation:

In geometry, transformations are used to move a point or points from one position to another.

Points A, C and D after [tex]90^o[/tex] clockwise rotation are: [tex]A' =(7,-2)[/tex], [tex]C' = (1,-7)[/tex] and [tex]D' = (1,-2)[/tex]Points A and B after [tex]270^o[/tex] clockwise rotation are [tex]A' = (-7,2)[/tex] and [tex]B' = (-7,7)[/tex].Points B and C after [tex]180^o[/tex] clockwise rotation are [tex]B = (-7,-7)[/tex] and [tex]C' = (-7,-1)[/tex].Points A and D after [tex]180^o[/tex] counterclockwise rotation are [tex]A = (-2,-7)[/tex] and [tex]D = (-2,-1)[/tex].Points C and D after [tex]90^o[/tex] counterclockwise rotation are [tex]C' = (-1,7)[/tex] and [tex]D' = (-1,2)[/tex].Point B after [tex]90^o[/tex] clockwise rotation is [tex]B = (7,-7)[/tex]

From the plane, we have the following coordinates:

[tex]A = (2,7)[/tex]

[tex]B = (7,7)[/tex]

[tex]C=(7,1)[/tex]

[tex]D = (2,1)[/tex]

When a point is rotated [tex]90^o[/tex] clockwise, the rule is:

[tex](x,y) \to (y,-x)[/tex]

So, the new points after A, C and D are rotated [tex]90^o[/tex] clockwise are:

[tex]A' =(7,-2)[/tex]

[tex]C' = (1,-7)[/tex]

[tex]D' = (1,-2)[/tex]

When a point is rotated [tex]270^o[/tex] clockwise, the rule is:

[tex](x,y) \to (-y,x)[/tex]

So, the new points after A and B are rotated [tex]270^o[/tex] clockwise are:

[tex]A' = (-7,2)[/tex]

[tex]B' = (-7,7)[/tex]

When a point is rotated [tex]180^o[/tex] clockwise and counterclockwise, the rule is:

[tex](x,y) \to (-x,-y)[/tex]

So, the new points after B and C are rotated [tex]180^o[/tex] clockwise are:

[tex]B = (-7,-7)[/tex]

[tex]C' = (-7,-1)[/tex]

And, the new point after A and D are rotated [tex]180^o[/tex] counterclockwise are:

[tex]A = (-2,-7)[/tex]

[tex]D = (-2,-1)[/tex]

When a point is rotated [tex]90^o[/tex] counterclockwise, the rule is:

[tex](x,y) \to (-y,x)[/tex]

So, the new points after C and D are rotated [tex]90^o[/tex] counterclockwise are:

[tex]C' = (-1,7)[/tex]

[tex]D' = (-1,2)[/tex]

Lastly, when a point is rotated [tex]270^o[/tex] counterclockwise, the rule is:

[tex](x,y) \to (y,-x)[/tex]

So, the new point after B is rotated [tex]90^o[/tex] clockwise is:

[tex]B = (7,-7)[/tex]

Answer:

n = 10 and n = 16

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then

[tex]4^{8}[/tex] × 4² = [tex]4^{(8+2)}[/tex]

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

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then

= [tex]3^{2(8)}[/tex]

= [tex]3^{16}[/tex] , thus n = 16

I'm confused on this.. here, there is this also,Egyptian ReligionThe Egyptian GodsThe first written records of religious practice in Egypt come from around 3400 BCE in the Predynastic Period of Egypt (6000-3150 BCE). Deities such as Isis, Osiris, Ptah, Hathor, Atum, Set, Nephthys, and Horus were already established as potent forces to be recognized fairly early on. The Egyptian Creation Myth is similar to the beginning of the Mesopotamian story in that, originally, there was only chaotic, slow-swirling waters. This ocean was without bounds, depthless, and silent until, upon its surface, there rose a hill of earth (known as the ben-ben, the primordial mound, which, it is thought, the pyramids symbolize) and the great god Atum (the sun) stood upon the ben-ben and spoke, giving birth to the god Shu (of the air) the goddess Tefnut (of moisture) the god Geb (of earth) and the goddess Nut (of sky). Atum had intended Nut as his bride but she fell in love with Geb. Angry with the lovers, Atum separated them by stretching Nut across the sky high away from Geb on the earth.Although the lovers were separated during the day, they came together at night and Nut bore three sons, Osiris, Set and Horus, and two daughters, Isis and Nephthys. Osiris, as eldest, was announced as Lord of all the Earth when he was born and was given his sister Isis as a wife. Set, consumed by jealousy, hated his brother and killed him to assume the throne. Isis then embalmed her husbands body and, with powerful charms, resurrected Osiris who returned from the dead to bring life to the people of Egypt. Osiris later served as the Supreme Judge of the souls of the dead in the Hall of Truth and, by weighing the heart of the soul in the balances, decided who was granted eternal life. The Egyptian AfterlifeThe Egyptian afterlife was known as the Field of Reeds and was a mirror-image of life on earth down to ones favorite tree and stream and dog. Those one loved in life would either be waiting when one arrived or would follow after. The Egyptians viewed earthly existence as simply one part of an eternal journey and were so concerned about passing easily to the next phase that they created their elaborate tombs (the pyramids), temples, and funerary inscriptions (the Pyramid Texts, the Book of the Dead) to help the souls passage from this world to the next.The gods cared for one after death just as they had in life from the beginning of time. The goddess Qebhet brought water to the thirsty souls in the land of the dead and other goddesses such as Selket and Nephthys cared for and protected the souls as they journeyed to the Field of Reeds. An ancient Egyptian understood that, from birth to death and even after death, the universe had been ordered by the gods and everyone had a place in that order.
