Use the equation y=mx+b where m is the slope (how much it increases each time) and b is the y intercept (starting point).
Your equation would be: y=12x+0 because they eat 12 pounds each day and they start out having eaten 0 pounds.
To solve the equation, plug in the total amount of food for y and use algebra to solve for x:
250=12x
(divide by 12)
(250/12)=x
X=20.833
Their food would last approximately 20 days. (Make sure you round if required)
To find the common ratio
divide by the previous numb/number beside it:

Answer:
3.528
Step-by-step explanation:
First, you need to determine the scale factor. Divide one side in the larger triangle by the corresponding side in the smaller triangle. For example, 8/2. This would give you a scale factor of 2. Then you can reverse the process with the dimensions you need to get the area. The height of the larger triangle is 3.36, so to find the height of the smaller one, you divide it by 2, or the scale factor, to get the height of the smaller triangle which is 1.68. Next, you can solve for area of triangle using a=bh/2, so 4.2*1.68/2=a = 3.528.
