Sophie has 5 pieces of string that are 4 yards each. She uses 3 pieces that are each 3 feet long. How much string does Sophie ha

stich3 [128]

Alright, lets get started.

Sophie has 5 pieces of string that are 4 yards each.

1 yards = 3 feet,

So, 4 yards = $4 * 3 =12$ feet

Total number of string she has = 5 piece

So, total length she has = $5*12 = 60$ feet

It means she had 60 feet string in starting.

Now, She uses 3 pieces that are each 3 feet long, means

She uses = $3*3 = 9$ feet

So, remaining string length will be = $60 - 9 = 51$ feet

Means 51 feet string does Sophie have. : Answer

Hope it will help :)

Determine whether the following function is a one-to-one function. If it is one-to-one, list the inverse function by switching

BartSMP [9]

Answer: An easy way to determine whether a function is a one-to-one function is to use the horizontal line test on the graph of the function. To do this, draw horizontal lines through the graph. If any horizontal line intersects the graph more than once, then the graph does not represent a one-to-one function.

i dont know the exact answer but its a lil sum

Step-by-step explanation:

We know that for any two inverses f(x) = g(y), meaning that if we take f(x) for any x in the domain of f(x), then g(y), where y is the outcome of f(x), should output x. So that is a simple test to see if two functions are inverses.
