Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need to make 5% syrup?
ICE Princess25 [194]

4.75 lbs of water and 0.25 lbs of sugar is needed to make 5% of syrup.

<u>Solution:</u>

Let us assume that x is the required pounds sugar to make 5% syrup

\Rightarrow\frac{x}{\text{total quantity}}=5\%

which is \frac{x}{5}=5\%

On solving we get,

\Rightarrow\frac{x}{5} =0.05 [5\%=\frac{5}{100}]

\Rightarrow x = 5\times0.05\rightarrow x=0.25

If the required sugar to make 5% syrup is 0.25 lbs then the remaining quantity in the total sugar syrup would be water. That is,

5 \text{ lbs }-0.25 \text{ lbs }=4.75 \text{ lbs }

So, the required amount is 0.25 lbs of sugar and 4.75 lbs of water.

Jana is decorating 6 picture frames by gluing straws around the borders and adding wooden stars at the corners. Each picture fra
zzz [600]

Answer:

C: 48 straws

Step-by-step explanation:

First, find the perimeter of one picture frame: (2 x length) + (2 x width).  Convert 20 centimeters to millimeters so that you are working in the same units; there are 10 millimeters in 1 centimeter, so 20 centimeters = 200 millimeters.  

(2 x 200) + (2 x 120) = 400 + 240 = 640

Each picture frame has a perimeter of 640 millimeters.

Next, figure out how many straws are needed for one picture frame:

640/80 = 8

Jana uses 8 straws for each picture frame.  Since she is decorating 6 picture frames, solve 6 x 8 = 48.  

Jana needs 48 straws to complete her project.
