55 minutes later than 11:55

iogann1982 [59]

Let's split it up to make it a little easier.
There's 50 minutes plus another 5 minutes that needs to be added to 11:55
Now, if we add the 5 minutes to 11:55, it becomes 12:00
And we simply have to add the other 50 minutes to 12:00, making it
12:50
So, 55 minutes later than 11:55 is 12:50

Using Rigid motion, explain in detail, why triangle ABC must be congruent to triangle DEF

weeeeeb [17]

Using rigid motion, both of these triangles will be congruent. The reason is because rigid motions include reflections, translations, and rotations.

None of these transformations will affect the size or shape of the figure, therefore keeping them congruent.

How much water do you add to make 12% sugar syrup using 5g sugar?

Alchen [17]

so the syrup is just water and sugar, we know that the sugar percent is just 12%, and that happens to be 5grams.

now 100% - 12% is 88%, so the 88% leftover will just be water.

if 12% is 5g, how much is 88%?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 5&12\\ x&88 \end{array}\implies \cfrac{5}{x}=\cfrac{12}{88}\implies \cfrac{5}{x}=\cfrac{3}{22}\implies 110=3x \\\\\\ \cfrac{110}{3}=x\implies 36\frac{2}{3}=x$
