Answer:
60 cups of flour
Step-by-step explanation:
Since it takes 20 cups of flour for 4 loves of bread this means we're going to need to multiply 20x3=60
X^2+10+25=35 if you put all numbers on one side it's:
x^2=35-10-25
x^2=0 square root
x=0
21+45+70=136
136+(2+x)=180
First subtract 136 from both sides
(2+x)=44=M<ROS
Subtract 2 from both sides
x=42
The number of cows is given by
So, after 
years, the number of cows will be
We want this number to be twice as much as the original:
First of all, we can cancel 14 from both sides:
Finally, on the right hand side, we can use the exponent rule
to get
To solve this equation, we must impose that the two exponents are the same:
And clearly this is true if and only if 
. So, it will take 5 years for the cow heard to double in number.
You can do the exact same steps to find the doubling time for the sheeps.
To find the amount of work done, we need to use the formula for work.
The formula is: Force x Distance.
The force being given is 50N, and the distance traveled is 3M.
With this information, we're ready to solve!
Let's plug in our numbers to the formula given above.
Work = 50 x 3
50 x 3 = 150.
The amount of work done is 150J.
I hope this helps!
