Answer:
The transformation
maps triangle XYZ onto triangle X”Y”Z”.
Step-by-step explanation:
Let us take point Z on the XYZ triangle and see what sequence of transformations we have to apply to map it into the point Z''.
Now Z = (-2, 2) and Z'' = (-7, -1).
The x-coordinate goes from -2 ⇒ -7.
The y-coordinate goes from 2 ⇒ -1.
The x-coordinate is just shifted by -5; thus, , and the y-coordinate first transforms as
, and is then shifted by 1; thus, it transforms as
.
So we have the full transformation
Answer:
The number of boys in the course will be = 140
Step-by-step explanation:
Given:
Total number of students enrolled in an introductory biology course = 364
There are 5 boys to every 8 girls in the course.
To find how many boys are in the course.
Solution:
Since, there are 5 boys to every 8 girls in the course.
So, ratio of boys to girls enrolled in the course = 5 : 8
Let the number of boys in the course be =
Then number of girls in the course will be =
Total number of students would be given as:
⇒ <em>Number of boys + Number of girls</em>
⇒
⇒
Total number of students given = 364.
Thus, we have:
solving for
Dividing both sides by 13.
∴
So, number of boys in the course will be = = 140
