Tom could know this because when multiplying two numbers that have decimals the decimal place in the answer will always have the same number of decimal places as the sum of the decimal places in the multiplied numbers.
sorry if this is too wordy for you. Hoped this helped you out though!
Answer:
45 degrees
Step-by-step explanation:
A circle is 360 degrees total so 360 - 315 is equal to 45 degree.
Answer:
A. (3/2)² = (9/4)
B. (-1/2)⁴ = (1/16)
C. (-1/3)³ = 1/81
D. (-4/5)⁰ = 1
E. (-5/9)¹ = (-5/9)
Step-by-step explanation:
A. (3/2)² = (9/4)
(3/2)*(3/2) numerators-<em>3*3=9</em> denominators-<em>2*2=4</em> (9/4)
B. (-1/2)⁴ =
(-1/2)*(-1/2)*(-1/2)*(-1/2)=(-1*-1*-1*-1)/(2*2*2*2)= (1/16)
C. (-1/3)³ =
(-1/3)*(-1/3)*(-1/3)*(-1/3)=(-1*-1*-1*-1)/(3*3*3*3)=(1/81)
D. (-4/5)⁰ =
Anything to the power of 0 is =1
E. (-5/9)¹ =
Anything to the power of one is itself = (-5/9)
