First add all of the values together
12 + 16 + 22 + 23 + 34 + 44 + 46 + 47 + 48 + 64 + 67 + 73 + 83 + 88 + 89 = 756
Then divide the answer by the total number of values
Number of values = 15
756 / 15 = 50.4
Answer:
It has a thick atmosphere which causes extremely high temperatures.
Step-by-step explanation:
venus's atmosphere is almost entirely carbon dioxide, and is also about 90x heavier than earth's atmosphere, which is similar to diving 3,000 feet below the ocean.
In conclusion, the answer would be "It has a thick atmosphere which causes extremely high temperatures."
Answer:
centre = (2, - 3 ) and radius = 5
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
given
x² + y² - 4x + 6y - 12 = 0 ( add 12 to both sides )
x² + y² - 4x + 6y = 12 ( collect x/ y terms )
x² + 4x + y² + 6y = 12
using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(-2)x + 4 + y² + 2(3)y + 9 = 12 + 4 + 9
(x - 2)² + (y + 3)² = 25 ← in standard form
with (h, k ) = ( 2, - 3 ) and r = = 5
Answer:
Sum of the three angles of a triangle is 180°(∠A+∠B+∠C=180°)
∠A+∠B+∠C = 110°+25°+x = 180°
<=> 135°+x=180°
<=>x=180°-135°=45°
Solve simultaneously:
<span>15x-8y=52 and
6x+14y=38

Let's solve this system thru elimination by addition/subtraction:
Let's get rid of the x terms.
To do this, mult. the first eqn. by -6 and the second by 15. (This is not the only way in which we can do this!!) We get
-90x + 48y = -312
90x +210y = 570
--------------------------
Add all 3 columns together. We end up with:
258y = 258, so y = 1. You can find x by subst. 1 for y in either of the given equations.
