Julia needs to cut a 15m rope into 20 equal pieces. Calculate the length of each piece in cm

Argh! My answer was erased!

We need to cut a 15m rope into 20 equal pieces. Written mathematically, it is as follows:
15/20 = length of rope segment in meters (a)
15/20 = a

Simplify
3/4 = a

In meters, each rope segment is 3/4m long.  But, we don't want meters.  We want centimeters.

100 cm = 1 m

3/4(100) = length of rope segment in centimeters (x)
3/4(100) = x

300/4 = x
75 = x

Each segment of rope is 75 cm long.

The rope needs to be cut into 20 pieces, so 15/20, this will give you 3/4 of a meter per piece. Multiply 100 (100 cm in a meter), .75*100= 75 centimeters in a piece...

Answer:

h = 19.7 ft.

Step-by-step explanation:

Use the Pythagoras Theorem

(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\\\(20)^2=(3.5)^2+(h)^2\\400=12.25+h^2\\400-12.25=h^2\\387.75=h^2\\

Now we take square root on both sides,

\sqrt{387.75} =\sqrt{h^2}\\19.69=h\\h=19.7\ ft\\

so the value of h equals 19.7 ft.

If 15% of an item is $18.00 what was the original price?
larisa [96]
<span>from the whole price,
15% of this price is equal to $18.00.
therefore if 15 % equals $18.00
                                                                     
then 100% is the original price therefore 100 % = 18.00 / 15 % x 100% = $120 therefore original price = $120</span>
