Answer:
Step-by-step explanation:
You can do this in a conventional mathematics way by showing each digit as an increasing power of 8, starting with zero
E.g 325 octal
(3 * 8 2 ) + (2 * 8 1 ) + (5 * 8 0 ) = (3 * 64) + (2 * 8) + (5 * 1)
i.e 192 + 16 + 5 = 197 decimal
Note: any number raise to power of 0 in indices is equal to 1
If an integer is both a square and a cube, it can be of the form:
<span>(<span>a3</span><span>)^2</span></span>
Now,
since a cube can be of the form 7k or 7k+-1(thanks to FoolForMath),
we write
<span><span>a^3</span>=7k</span>
and get the no to be
49k^2
, which is in the form of 7 times something
<span>49<span>k^2</span>=7×(7<span>k^2</span>)</span>
Now put
<span><span>a^3</span>=7k+−1</span>
Square it
and you'll get a number in the form of (7times something +1)
Answer:
Conjecture: "The product of any two odd integers is an odd integer."
The given equation y = (-4/7)x + 9 is already in slope intercept form. It matches up with y = mx+b where
m = -4/7 is the slope
b = 9 is the y intercept
Therefore, the answer is choice D
Answer:
FICA tax should his employer withhold be $24.92 .
Option (D) is correct .
Step-by-step explanation:
As given
Bill’s FICA tax is 7.65% of his earnings of 325.78 per week.
7.65 % is written in the decimal form.
= 0.0765
FICA tax price = 0.0765 × Earning of a week
Putting values in the above
FICA tax price = 0.0765 × 325.78
= $ 24.92 (Approx)
Therefore the FICA tax should his employer withhold be $24.92 .
Option (D) is correct .
