Answer:
The area of triangles are 16 cm^2 and 49 cm^2
Step-by-step explanation:
we know that
If two figures are similar, the ratio of its perimeters is equal to the scale factor and the ratio of its areas is equal to the scale factor squared
Let
z ----> the scale factor
x ----> the area of the smaller triangle in square centimeters
y ----> the area of the larger triangle in square centimeters
we know that
so
-----> equation A
----> equation B
solve the system by substitution
substitute equation A in equation B
solve for y
Find the value of x
therefore
The area of triangles are 16 cm^2 and 49 cm^2

Answer:
B. Carl yearns more per hour
C. put line through points (1,15) and 3,45) on graph and you will have Carl's earnings per hr.
Step-by-step explanation:
Louis earns 12$ per hr (y=12x)
Carl yearns 15$ per hr (y=15x)
to find what carl yearns hourly you divide 45 by 3 which is 15.
(Explaination of answer for question b)
C isnt hard once you find y=15x.
There are 65 boys, and the boy ratio is 13: so to find how they got that, divide 65 by 13 and that is 5. Since we now know it is the amount of people, divided by 5, we can take the girl ratio (15) and multiply it by 5 to get the amount of girls (which is 75). You need to find the total amount of students in the class so add the boys and girls (65+75) and get 140 total students
