Answer:
The percent change in salary from one job to the next is 88.57%.
Step-by-step explanation:
The previous salary of per hour = $8.75 per hour
The current salary of per hour = $16.50 per hour
Change in the salary rate per hour = Current salary - Previous Salary
= $16.50 per hour - $8.75 per hour
=$7.75 per hour
⇒The change in the salary per hour rate is $7.75
Now,
=
or, the change in salary percentage is 88.57%
Hence, the percent change in salary from one job to the next is 88.57%.
Answer:
They are similar by the definition of similarity in terms of a dilation
Step-by-step explanation:
The given vertices of triangle ΔABC are;
A(1, 5), B(3, 9), and C(5, 3)
The vertices of triangle ΔDEF are;
D(-3, 3), E(-2, 5), and F(-1, 2)
Therefore, we get;
The length of segment, = √((9 - 5)² + (3 - 1)²) = 2·√5
The length of segment, = √((9 - 3)² + (3 - 5)²) = 2·√10
The length of segment, = √((5 - 3)² + (1 - 5)²) = 2·√5
The length of segment, = √((5 - 3)² + (-2 - (-3))²) = √5
The length of segment, = √((2 - 5)² + (-1 - (-2))²) = √10
The length of segment, = √((2 - 3)² + (-1 - (-3))²) = √5
∴ /
= 2·√5/(√5) = 2
/
= 2·√10/(√10) = 2
/
= 2·√5/(√5) = 2
The ratio of their corresponding sides are equal and therefore;
ΔABC and ΔDEF are similar by the definition of similarity in terms of dilation.
