5 2/8 beacuse if you add it up that what it makes
Answer:
B. $8
Step-by-step explanation:
Given:
Total payment, T = $160
Hourly rates = $t/hour
= total payment/total time worked
The question said, "worked 12 more hours than the amount she is paid per hour".
Total time worked = (12 + t) hour
Therefore, Hourly rates of payment, t = 160/(12 + t)
t^2 + 12t - 160 = 0
Solving the above quadratic equation,
t = -20 and 8
t = $8
A percentage is a way to describe a part of a whole. The missing percent on the bar model is equal to 12.5%.
<h3>What are Percentages?</h3>
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
On the percent bar model, above the missing percentage, the fraction is given as 1/8.
Now, the given fraction 1/8 in the form of percentage can be written as,
1/8
= 1/8 × 100%
= 0.125 × 100%
= 12.5%
Hence, the missing percent on the bar model is equal to 12.5%.
