Answer:
The distance would be .
Step-by-step explanation:
The least distance between them would be to draw a straight line between them.
By calculating the distance between the y values and the x values, you can calculate the distance.
y values:
|5 - 1| = 4
x values:
|6 - -3| = 9
| | = the absolute value, meaning you change the final sign to positive.
Use the Pythagorean theorem and substitute the numbers in.
Answer: 30% change in the number of unemployed construction workers over this period
Step-by-step explanation:
September 1, 1992
The total number of construction workers = 1,000 (assume);
16% are unemployed, so the number of unemployed workers is 16*1000/100= 160.
September 1, 1996
The total number of construction workers 20% greater 20*1000/100+1000=1200;
9% are unemployed, thus the number of unemployed workers = 9*1200/100=108.
Decrease is 52, which is approximately 30% of 160.
