Step-by-step explanation:

On the right side, 3 + 4 + 7 = 14, so the other two numbers must add up to 22. Therefore, they must be 10 and 12.

Let's assume 12 is the top number and 10 is the bottom number.

The left side adds up to 12 + 9 + 2 = 23, so the other two numbers add up to 13. Therefore, they must be 5 and 8.

The bottom side adds up to 10 + 1 + 11 = 22, so the other two numbers add up to 14. Therefore, they must be 6 and 8.

So the bottom left number is 8.

Answer:

0.17

Step-by-step explanation:

First, we can easily calculate that the area of the rectangle is 7 * 5 = 35

Next, to find the probability of choosing a point in the triangle, we need to find the area of the triangle compared to the area of the rectangle. Notice that the square has nothing to do with the solution because we are only interested in finding the probability for the triangle!

Since the area of the triangle is base * height / 2 or 4 * 3/2 = 6, the probability is 6/35. Plugging this value in the calculator gives us 0.17

Which is the better buy 7 pounds for $8.47 or 9 pounds for $11.07

Nesterboy [21]

First we find the average cost per pound...
(7n)/7 = ($8.47)/7 = $1.21 per pound
(9n)/9 = ($11.07)/9 = $1.23 per pound

$1.21 is the cheapest price per pound, so 7 pounds for $8.47 is a better buy

Answer = 7 pounds for $8.47 is the best buy
