This is a question that will require Pythagoras' theorem as you want to find the length of a diagonal of a triangle and are given the measurements of two sides. I have attached a picture of how to solve this problem.
To the nearest 10th of a foot, the answer is 77.6ft
need more details to answer please post the question with more details
Answer:
Step-by-step explanation:
make 4 a fraction then times
keep flip change (kfc)
3/8 times 4/1
equals 3/2
Lets make the cost of the algebra textbook = x and the cost of the geometry book = y
2x+3y=64
4x+2y=66
now we get one of these equations in terms of one variable
2x+3y=64 ---> 2x=64-3y ---> x=32-1.5y
now we can plug that numeric value back into the other equation
4(32-1.5y)+2y=66
we can now simplify this equation in order to get the value of y
4(32-1.5y)+2y=66 ---> 128-6y+2y=66 ---> 128-4y=66 ---> -4y=-64 ---> y=16
