Answer:
Order from Least to Greatest
:
-10 < -6/40 < -2/25 < 5/20
Answer:
C. 42
Step-by-step explanation:
<em>Since the triangle making up the base of the right triangular pyramid is equilateral, the three lateral triangles will have equal areas. To find the surface area of the pyramid, find the area of one of the lateral triangles and multiply it by 3. Then, add that to the area of the triangle that forms the base.</em>
<em>Area of Lateral Triangle = 1/2 · base · height</em>
<em> = 1/2 · X · Z</em>
<em> = 1/2 · 4 units · 6 units</em>
<em> = 12 square units</em>
<em>Area of Base Triangle = 1/2 · base · height</em>
<em> = 1/2 · X · Y</em>
<em> = 1/2 · 4 units · 3 units</em>
<em> = 6 square units</em>
<em>Now, use the method described above to find the surface area of the pyramid.</em>
<em>Surface Area = 3( Area lateral ) + ( Area base )</em>
<em> = 3 ( 12 square units ) + ( 6 square units )</em>
<em> = 42 square units</em>
The answer should be the very last option. An equation where the highest exponent of the variable (usually x) is a square (2).
Multiply the first equation by -666 and the second by 45:-
-29970x + 217116y = -63936
29970x - 34965y = 18900
adding these 2 equations:-
182151y = -45036
y = -0.24724
x = 96 + 326* -0.24724 / 45 = 0.3422
x = 0.342, y = -0.247 Answer (correct to the nearest thousandth)
