Answer:
-9 1/3
Step-by-step explanation:
Step 1. turn the the second fraction upside down which it then becomes a reciprocal
Step 2. then multiply the first fraction by that same reciprocal that you found
Step 3 simplify the fraction
Function F goes in the first one, G goes in the second one, and H goes in the last one. Hope this helps :)
Answer:
B.) 4,096 feet
Step-by-step explanation:
You were given a time, and time in the equation is represented by "t". To find the height, represented by "h", you just need to plug the given value in for "t" and simplify to find "h".
t = (1/4)√x <--- Original equation
16 = (1/4)√x <--- Plug 16 in "t"
64 = √x <--- Divide both sides by (1/4)
4,096 ft = x <--- Square both sides

Answer: t = (3/4)h hours.
Therefore, it takes both of them (3/4)h hours to complete the task.
Step-by-step explanation:
Let
t1 represent the time taken for the one worker to complete a task.
t2 represent the time taken for the second worker to complete a task
And t represent the time taken for both.
t1 = h
t2 = 3h
Let x represent the task.
x = rate × time
r1,r2 and r are the rates at which first, second and both worker works
x = r1(t1). .....1
x = r2(t2). ....2
x = r(t) ....3
And,
r = r1 + r2. ( Rate of both equals sum of rates of the two)
From eqn 1 and 2
r1 = x/t1 = x/h
r2 = x/t2 = x/3h
r = r1 + r2 = x/h + x/3h = 4x/3h
Substituting r = 4x/3h into equation 3
x= r(t)
x = (4x/3h)t
Making t the subject of formula
t = x/(4x/3h)
t = 1/(4/3h)
t = 3h/4
t = (3/4)h hours.
Therefore, it takes both of them (3/4)h hours to complete the task.
