it represents and the relative amount of energy in the trophic level.i think sorry if I am wrong
Try with 9,135, I think this one is correct
Answer:
∠BAD = 109°
∠DAC = 111°
Step-by-step explanation:
This is essentially a triangle, correct? Something to know is that these angles in a triangle add up to 360°.
In mathematical terms, this would look like: 140 + (2x + 4) + (2x + 6) = 360
Now, we solve for x.
140 + (2x + 4) + (2x + 6) = 360 (Subtract 140 from both sides to get x's on one side)
2x + 4 + 2x + 6 = 220 (Add like terms: 2x + 2x and 4 + 6)
4x + 10 = 220 (Subtract 10 from both sides to get x on one side)
4x = 210 (Divide both sides by 4 to get x by itself)
x = 52.5
Now that we know what x equals, we can plug it in to find ∠<em>BAD</em> and ∠<em>DAC</em>.
2x + 4 → 2(52.5) + 4 = 109
2x + 6 → 2(52.5) + 6 = 111
Answer:
Step-by-step explanation:
Volumes of two spheres A and B = 648 cm³ and 1029 cm³
Things to remember:
1). Scale factor of two objects = [ and are the radii of two circles]
2). Area scale factor =
3). Volume scale factor =
Volume scale factor Or Volume ratio =
Therefore, scale factor =
≈ 6 : 7
Area scale factor Or area ratio =
=
≈ 36 : 49
Volume scale factor or Volume ratio =
=
≈ 216 : 343
