Answer:
steepness
Step-by-step explanation:
This is a lot of calculation.
So we know that the sum of angles for any heptagon is 900, because heptagon can be divided into five non-overlapping triangles and sum of angles of each triangle is 180.
Now you just add up all angles and simplify the equation:
900 = (6x - 8) + 120 + (7x - 64) + (5x - 4) + 135 + (3x + 31) + (4x + 15)
900 = <span>25x + 225
Now it's just regular algebra equation. You can solve for x:
675 = 25x
x = </span>27
So the value of x is 27
Answer:
B = 64° , C = 26°
Step-by-step explanation:
2x+x-6+90 =180
3x + 84 = 180
3x = 180 - 84
3x = 96
x = 32°
B = 2x
B = 2 * 32
B = 64°
C = x - 6
C = 32 - 6
C = 26°
Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368
mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?
We can figure this out using scientific notation.


Put 3.04e-7 in standard notation.

Put 0.00000304 back into scientific notation, instead with a multiply sign.
Move the dot back, making the number in between 1-10.
In this case, we would move it back 7 times.
· 
So the answer would be A.
