Answer:
Step-by-step explanation:
Part A can be seen in the attached picture below. Since there are 76 students that have both a license and a job we need to subtract 76 from each to get the amount that only have either a license or a job as seen in the table. Also we can see from the table that it sums up to 145 students, meaning that 5 students do not have neither a job or a license.
Part B, to calculate this we need to divide the amount of students that ONLY have a job by the total amount of students that have a job (since the rest of those students also have a license) Therefore:
17 / 93 = 0.1828
Now we can multiply this result by 100 to get the percentage.
0.1828 * 100 = 18.28%
Answer:
The sides of the triangle are:
Second side = 60 cm
First side = 55 cm
Third side = 50 cm
The perimeter equation can be given as:
Step-by-step explanation:
Given:
Perimeter of triangle = 165 cm
First side = 65 cm less than twice the second side
Third side = 10 cm less than the second side
To find length of each side and write the equation that represents the perimeter of triangle.
Solution:
Let length of second side be = cm
First side will be given as = cm
Third side will be given as = cm
Perimeter of triangle = Sum of all sides
Thus, perimeter can be given as:
⇒
⇒
Simplifying by combining like terms.
⇒
We know the perimeter of triangle = 165 cm
So, the perimeter equation can be given as:
Solving for .
Adding 75 both sides.
Dividing both sides by 4.
Thus, the sides of the triangle are:
Second side = 60 cm
First side = = 55 cm
Third side = = 50 cm
