Number 2 would be b. 7/12= 0.583 repeating
Answer:
x = 18.
Step-by-step explanation:
x / 1.2 = 15
To isolate x we multiply both sides of ther equation by 1.2:
x = 15 * 1.2
x = 18 (answer).
Answer:
Correct option: c)
radius = 6 inches
Step-by-step explanation:
The complete arc of a circumference has 360 degrees, and the length is 2*pi*radius
Knowing this, we can use a rule of three to solve this problem:
144 degrees - > 15 inches
360 degrees -> 2 * pi * radius
144/360 = 15/(2pi*radius)
2pi*radius = 360 * 15 / 144
radius = 37.5/(2pi)
radius = 5.9683 inches
Rounding to nearest whole number, we have radius = 6 inches
Correct option: c)
Answer:
The answer is 1/9 ⇒ the second answer
Step-by-step explanation:
* In the exponential functions we have some rules
(1) b^(-m) = 1/(b^m) (for all nonzero real numbers b)
- If we have negative power we reciprocal the base
to get positive power
(2) (b^m)^n = b^(mn)
- If we have power over power we multiply them
* In our problem: 
- At first change 27 to b^n
∵ 27 = 3 × 3 × 3 = 3³
∴ 
* Lets use rule (2)
∴ 
⇒ 3 × -2/3 = -2
* Use rule (1)
∴ 
⇒ reciprocal the fraction to change the sig of the power
* The answer is 1/9
