Answer:
2/3
Step-by-step explanation:
Let n = the repeating, non-terminating number 0.666...
We now have n = 0.666666...
We want the number n in the form of a fraction.
Since only 1 digit repeats, the 6, use a 1 followed by 1 zero, which means the number 10. Now multiply both sides by 10 and write the original equation below it.
10n = 6.666666...
n = 0.666666...
Subtract the bottom equation from the top equation.
9n = 6
n = 6/9
n = 2/3
Omar spent 600 dollars for earning 1800 reward points.
<em><u>Explanation</u></em>
Omar earns 300 reward points for every 100 dollars he spends.
Suppose, he spent
dollar for 1800 reward points.
Now <u>according to the ratio of "amount of money spent" and "reward points"</u> , the equation will be......

Thus, Omar spent 600 dollars for earning 1800 reward points.
50% is 30, it’s half of 60. 25% is the same as dividing by 4, 60/4 is 15.
Answer:
Horizontal distance between lifeguard and the person is 22 feet.
Step-by-step explanation:
Given: A lifeguard sees a person in distress.The eye level of the lifeguard is 15 feet above the ground. Angle of depression is 34°.
To find: Horizontal distance between lifeguard and the person.
Solution : If we draw a triangle then tan∅ = 
Here base is the horizontal distance.
Now we put the values in the formula.
tan 34° = 
Or Base = 
= 
So the answer is 22 feet.
