Why is the straightedge of a ruler not the same as a line?

vampirchik [111]

Answer:

A straightedge is used only to make or draw a straight line but not to measure the length as it does not have measurement gradients. A ruler has two parallel lines or edges which have centimeters and millimeters on one side and inches on the other.

Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need to make 75% syrup?

Julli [10]

Answer:

He needs 3.75 lbs of sugar and 1.25 lbs of water.

Step-by-step explanation:

Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.

Note

5 lbs - 100%

x lbs - 75%

Write a proportion:

$\dfrac{5}{x}=\dfrac{100}{75}$

Cross multiply:

$100x=5\cdot 75\\ \\100x=375\\ \\x=\dfrac{375}{100}=3.75$

So, he needs 3.75 lbs of sugar and 5 - 3.75 = 1.25 lbs of water.
