Three of the angles of quadrilateral are 100 degrees, 104 degrees and 44 degrees. what is the size of the 4th angle

112°

Step-by-step explanation:

the sum of the 4 angles of a quadrilateral = 360°

To find the fourth angle, sum the 3 given angles and subtract from 360

fourth angle = 360° - (100 + 104 + 44 )° = 360° - 248° = 112°

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
