From the graph we can see that the base AC = 7 units
Height of the triangle AB = 4 units
Area of the triangle ABC = * base * height
= * 7 * 4
= 14 square units
Answer:
B
Step-by-step explanation:
A proportional relationship is represented by linear function with its linear parameter "b" equal to zero. Since b is equal to zero, the line passes through the origin and the function/relation is proportional.
To verify that we divide the y coordinate over the x coordinate we obtain a constant called k, which is the slope.
For instance:
According to this function we can easily check a proportional relationship among its points:
The school council will have 216 small sandwiches.
Step-by-step explanation:
Sandwiches ordered = 12
Length of one sandwich = 6 feet
1 foot = 12 inch
6 feet = 12*6 = 72 inches
Length of one sandwich in inches = 72 inches
As one small sandwich is 4 inches,
Number of small sandwiches in one sandwich =
One sandwich = 18 small sandwiches
12 sandwiches = 18*12 = 216 small sandwiches
The school council will have 216 small sandwiches.
