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)
Answer:
You could by 8 magazines
Step-by-step explanation:
First, set up the equation 6/12=x/16
cross multiple to get 12x=96
divide both sides by 12 and x = 8
Answer:
As Given, x+y=w+z
To Prove: AOB is a line or x+y=180
∘
(linear pair.)
According to the question,
x+y+w+z=360
∘
∣ Angles around a point.
(x+y)+(w+z)=360
∘
(x+y)+(x+y)=360
∘
∣ Given x+y=w+z
2(x+y)=360
∘
(x+y)=180
∘
Hence, x+y makes a linear pair.
Therefore, AOB is a straight line
1600<2570-125.5x<2000 subtract 2570 from all terms...
-970<-125.5x<-570 divide all terms by -125.5 (and reverse signs because of division by a negative!)
7.73>x>4.54 and x is months since January, and since months can only be integers...
x=[5,7]
So January + 5, 6, and 7 respectively are the three months that satisfy the equation...
June, July, and August.
