Astudent wrote four statements during math class. which statement contains an error? a. if iesha traveled at an average speed of 38 miles per hour for 18 hours, she traveled 684 miles. b. if jason traveled at an average speed of 46 miles per hour for 16 hours, he traveled 736 miles. c. if charmaine traveled at an average speed of 54 miles per hour for 14 hours, she traveled 766 miles. d. if raphael traveled at an average speed of 68 miles per hour for 12 hours, he traveled 816 miles.

C.

Step-by-step explanation:

speed * time = distance

In each case, multiply the speed by the time. The distance that is not the product is incorrect.

C. 54 * 14 = 756, not 766

C.

Step-by-step explanation:

A. 38 miles x 18 hours = 684 miles. (correct)

B. 46 miles x 16 hours = 736 miles. (correct)

C. 54 miles x 14 hours = 756 miles. (here's the error, statement C says it is 766 miles.)

D. 68 miles x 12 hours = 816 miles. (correct)

true

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.
