Answer:

EF = 8.8 cm

Step-by-step explanation:

In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;

/hyp/^{2} = /adj1/^{2} + /adj2/^{2}

/DE/^{2} = /EF/^{2} + /DF/^{2}

/16.2/^{2} = /EF/^{2} + /13.6/^{2}

262.44 = /EF/^{2} + 184.96

/EF/^{2} = 262.44 - 184.96

          = 77.48

EF = \sqrt{77.48}

     = 8.8023

EF = 8.8 cm

The length of side EF is 8.8 cm.

What is the Order of Magnitude of the number of pennies equivalent to a quarter?​
Talja [164]

Answer:

It is mainly used while doing scientific notation. If two numbers differ by one order of magnitude, one is about ten times larger than the other. If they differ by two orders of magnitude, they differ by a factor of about 100.A quarter is 0.25 dollars so the ratio between 1 dollar and a quarter is 1/0.25(it means the dollar and the quarter which is 0.25 dollars) and that equals =4
