Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need… b …to make 20% syrup? Answer: lbs of
Nutka1998 [239]

Answer:

Mom would required 1 lbs of Sugar and 4 lbs of water.

Step-by-step explanation:

Given:

Amount of Sugar syrup Mom wants to make = 5 lbs

Percentile amount of syrup she needs to make = 20%

Solution:

Let amount of sugar to make 20% syrup be 'x'.

So by definition of proportion we get;

\frac {x}{5}=\frac{20}{100}

Now Multiplying both side by 5 we get;

\frac {x}{5}\times5=\frac{20}{100}\times5\\\\x=1\ lbs

So we can say that;

Amount of water = 5-1=4 \ lbs

Hence Mom would required 1 lbs of Sugar and 4 lbs of water.

The function f(x) = StartRoot negative x EndRoot is represented by the graph. Which statement is correct?
Svetlanka [38]

Answer:

D. The range of the function is all real numbers greater than or equal to 0.

Step-by-step explanation:

The graph of the function y=\sqrt{-x} is shown in attached diagram.

1. The domain of the function is the set of all possible values for input (for x). Hence, the domain of this function is

x\in (-\infty,0]

2. The range of the function is the set of all possible values for output (for y), so the range of this function is

y\in [0,\infty)

As you can see, only option D is true - The range of the function is all real numbers greater than or equal to 0.
