5 squares are placed end to end as below (see pic). What is the perimeter of the rectangle formed by the squares?
Nataly_w [17]
2b: If x is 2.1, then one side of the rectangle is 2.1, and another is 2.1*5=10.5.  Thus, the perimeter is 2*(2.1+10.5)=2*12.6=25.2.

3: One side of the square with side-length three will not be on the outside, so we have 3*3=9 inches perimeter from the square of side-length 3.  The square of side-length 6 has 3 from the top side missing from the outer perimeter, because it coincides with a side of the square of side-length three.  This square contributes 6*4-3=33 inches.  The total perimeter is 33+9=42 inches.

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

An equal mass of silver will displace a different volume of fluid than that displaced by gold.

<h2>Archimedes principle</h2>

According to the Archimedes principle, when an object is partially or completely immersed in water, the object will experience a force that displaces its own weight of fluid.

Therefore, when the jeweler deceptively replaced “an equal weight” (or equal mass) of gold with silver, we can know that by observing the volume of water displaced in each case. An equal mass of silver will displace a different volume of fluid than that displaced by gold.
