Answer:
24
Step-by-step explanation:
Area of a triangle
A = 1/2 bh
b=12
h=4
A= 1/2 * 12 * 4
A = 24
Answer:
x = 9
y = 6
Step-by-step explanation:
3x+6i=27+yi
The real components have to be equal and the imaginary components have to be equal
3x = 27
divide by 3
3x/3 = 27/3
x=9
6i = yi
Divide by i
6 = y
The equations has the form:
c=mt, where m is the constant of proportionality
If we isolate m in the equation above:
c=mt
c/t=mt/t
c/t=m
m=c/t
m is c divided by t
If we take the values of the table, and divide c by its correspondent t, we get:
m=c/t=25.50/3=34.00/4=42.50/5=51.00/6=59.50/7→m=8.5
Then: c=8.5t
Answer: The equation that represents the proportional relationship in the table is: Second option
