Hi!
The simple explanation is just, since there are half as many cows, then the grain will last two times more.
But here's why. How many times are you going to be feeding the cattle, over 10 days, if you feed them once per day? 60 * 10 = 600, so 600 times.
If you're still feeding them once per day, and there are 30 cows instead, then find how many times 30 goes into 600. 600 / 30 = 20 days. That's a method you can use, no matter what, even if it's, say 50 cattle. You would still get an answer (if it was 50, 600 / 50 = 12, so 12 days).
Hope this helped!
Answer:
Step-by-step explanation:
It is given that the length of triangle base is 26, then let ABC be the triangle and BC be the base of the triangle=26.Let DE be the parallel line to the base that divides triangle ABC into two equal area parts.
Now, Let AD=a, DB=b, DE=c, AE=d and EC=e, then
Since, triangle ABC is similar to triangle ADE, thus using basic proportions, we get
Taking the first two equalities,we get
Thus, the length of the segment between triangle legs is 
Answer:
-9-5x
Step-by-step explanation:
they aren't the same because of the variable on 5x. You can simplify the problem to -9-5x but that's about it unless it equals something.
Answer:
3/32
Step-by-step explanation:
Average rate of change refers to the slope of a function/equation.
To solve this, plug in for both x values and calculate the average, or mean.
x = 1
f(1) = 5(2)^1
= 5(2)
= 10
x = 5
f(5) = 5(2)^5
= 5(32)
= 160
Now, you calculate the average:
10 + 160 = 170
Divide by 2 and you get 85.
