Nancy is making a kite based on the pattern below. About how much binding does Nancy need to cover the edges of the kite?
Ainat [17]

Check the picture below.

so the perimeter of the kite is x+x+y+y, namely 2x + 2y.


\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c=\sqrt{a^2+b^2} \qquad \begin{cases} c=\stackrel{hypotenuse}{x}\\ a=\stackrel{adjacent}{8}\\ b=\stackrel{opposite}{15}\\ \end{cases} \\\\\\ x=\sqrt{8^2+15^2}\implies x=\sqrt{289}\implies \boxed{x=17} \\\\[-0.35em] ~\dotfill

\bf \begin{cases} c=\stackrel{hypotenuse}{y}\\ a=\stackrel{adjacent}{8}\\ b=\stackrel{opposite}{4}\\ \end{cases}\implies y=\sqrt{8^2+4^2}\implies y=\sqrt{80}\implies \boxed{y\approx 8.94} \\\\[-0.35em] ~\dotfill\\\\ 2x+2y\implies 2(17)+2(8.94)\implies 51.88\implies \stackrel{\textit{rounded up more}}{51.9}

Ivanna deposits $600 into an account that pays simple interest at a rate of 3% per year. How much interest will she be paid in t
andrezito [222]
Given here,

Principle [P] = $600

Rate [R] = 3

Time [T] = 2

We know,

Simple Interest = \frac{Principle * Rate * Time}{100}

=  \frac{600*3*2}{100} &#10;= 36

Weather records show that the probability of rainfall in Florida in June is 0.86. What is the probability that it rains there in
Lubov Fominskaja [6]
R - it is rain  (probablity: 0.86)
N - it is not rain (probablity: 1-0.86 = 0.14)
You've got these cases:

R R R R R R R R R N
R R R R R R R R N R
R R R R R R R N R R 
. . . 
N R R R R R R R R R     -  it is 10 cases.  Probablity each case is
(0.86)^9 * 0.14 - it is approximately  0.036   (9R and 1N - you multiply everything)

It is 10 cases so you have to multiply by 10  and you get 0.36

There is also eleventh case:

R R R R R R R R R R 

Probablity is (0.86)^10 approximately 0.22

Add these cases and you'll get your probablity:  0.36 + 0.22 = 0.58
