Answer:
15 boys
Step-by-step explanation:
There are 27 students. The number of girls is only 4/5 of the number of boys. I started by splitting the class. 14 boys and 13 girls doesn't work, so I changed it to 12 and 15. If it was 12 girls and 15 boys, the girls would have 4/5 of the boys, so it must be 12 girls and 15 boys.
Let x represent the height of the person and y the weight.
y - 180 = (80 - 180)/(4 - 6) (x - 6)
y - 180 = -100/-2 (x - 6) = 50(x - 6) = 50x - 300
y = 50x - 300 + 180 = 50x - 120
y = 50x - 120
A person 5.5 feet tall will weigh 50(5.5) - 120 = 275 - 120 = 155 pounds.

Step-by-step explanation:
Use definition of the absolute value of the number x:
1. When then
so using the definition,
2. When then
so using the definition,
Here it is. I wrote it down on paper since it is faster to write down the answer then to type on my iPad.
The value of the function is 157.5
<h3>How to evaluate the function?</h3>
The function is given as:
f(80)=1000(0.5)^(80/30)
Evaluate the quotient
f(80)=1000(0.5)^(8/3)
Evaluate the exponent
f(80)=1000 * 0.15749013123
Evaluate the product
f(80) = 157.49013123
Approximate
f(80) = 157.5
Hence, the value of the function is 157.5
