Harold stores 10656 pounds of grain for his 24 cattle.Each cow eats about 12 pounds of grain each day.how many days would the fo
olganol [36]

Hey there!

If he has 24 cattle that eat 12 pounds of grain every day, then the amount of grain that they eat every day can be represented by the following equation:

p = 24 x 12       Multiply the two together, and the amount eaten each day is 288 pounds.

We can divide 10656 by 288 to figure out how many times 288 will go into 10656, which tells us how many days the supply will last.

10656 ÷ 288 = 37

So this means the food supply will last 37 days.

Hope this helps!

For 5) alternate interior angles formed by parallel lines are congruent so if that angle is 120 degrees then it's alternate interior angle (the one with the question mark) is also 120 degrees
For 7) verticals angles are congruent as well so it would too, be 70 degrees
