Answer:
The correct answers are A and B. The planet whose temperature is closest to 0ºC is Earth, and the one whose temperature is farthest to 0ºC is Venus.
Step-by-step explanation:
As established by the table, the Earth has an average ambient temperature of about 7ºC, which moves 7 units of measurement away from the value of 0ºC, which makes the planet from the list with a temperature closer to 0ºC.
In turn, Venus has a temperature of 449°C, which removes it 449 degrees from the temperature of 0°C, thus making it the planet on the list whose temperature is the furthest from 0ºC.
Answer:
880
Step-by-step explanation:
Given:
Price of gold in 2001 = (0.5x+300)
Its price tripled in 2008 and then doubled in 2011. In 2016, its price dropped to of the price in 2011.
To find:
An expression for the price of gold per ounce in 2016.
Solution:
We have,
Price of gold in 2001
Its price tripled in 2008.
Price of gold in 2008
Then doubled in 2011.
Price of gold in 2011
In 2016, its price dropped to of the price in 2011.
Price of gold in 2016
Therefore, the required expression for the price of gold per ounce is (2x+1200).
The given samples are supposed to weigh 25.0 grams. This value is the basis when we talk about accuracy. In this case, we are talking about precision, so we opt to select the most 'precise' of the choices. The most precise measurement is C) 25.0122 grams. This is because it records up to +- 0.0001 grams.
Answer:
The equation of the given circle is x

=25
⇒ Centre =(0,0) and radius =5
Distance between point (−2.5,3.5) and centre (0,0)
=
(−2.5−0)

=
6.25+12.25
=

=4.3(approx)<5
Since the distance between point (−2.5,3.5) and centre (0,0) of the circle is less than the radius of the circle.
Hence the point (−2.5,3.5) lies inside the circle.
