192 = total beads

necklace + bracelet = 192

Let x equal the number of beads

bracelet = 5x
necklace = x

5x + x = 192

6x = 192

x = 32

It takes 32 beads to make a necklace

Work out the length of X.

vlabodo [156]

Answer:

By Pythagoras theorem

H^2=P^2+B^2

25^2=x^2+24^2

625=x^2 + 576

625-576=x^2

49=x^2

x^2=49

x=√49

x=7cm

Hope this helps uhh

A wood board 156 centimeters long is cut into three parts .The two longer parts are the same length and are 15 centimeters longe

n200080 [17]

The everyone of two longer parts has 57 cm length and the shortest part has 42 cm length.
less 30cm from 156 and divide the remain amount of 126 into three parts. The answer will be 42 cm, then add 15,15 in longer parts.

A cylindrical can has a volume of 2in^(3). Express the surface area of the can as a function of its radius,r.

noname [10]

$V=2 \text{ in}^3\\
A=2\pi r (r+h)\\
h=?\\\\
V=\pi r^2h=2\\
\pi r^2h=2\\
h=\dfrac{2}{\pi r^2}\\
A=2\pi r\left(r+\dfrac{2}{\pi r^2}\right)\\
\boxed{A=2\pi r^2+\dfrac{4}{r}}
