Joe is shown 3 cards marked 2 ,5, and 9, he selects these in random order, to give a three digit score. What is the sum of all possible scores

3,552

Step-by-step explanation:

The possible scores are

259, 295,529, 592, 952, 925

These are all the possibilities from his selection. Hence the sum of all possible scores may be computed as

= 259 +295 + 529 + 592 + 952 + 925

= 3,552

the sum of all possible scores is 3,552

center= (-2,0)

radius= sqrt2/2

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.
