Andrew [12]

ANSWER

D. 18 m^2

EXPLANATION

The area of a kite is half the product of the diagonals.

The diagonals of the kite are

3+3=6m

and

2+4=6m

The area of the kite

$= \frac{1}{2} \times 6 \times 6$

$= 3 \times 6$

$= 18 {m}^{2}$

The correct answer is D.

Please solve this for me thank you!

Answer:

620.14

Step-by-step explanation:

Original Equation:

$\frac{4y}{1.025^4}+y-2y(1.05)^2=1500$

Calculate exponents

$\frac{4y}{1.103812890625}+y-2y(1.1025)=1500\\$

Simplify:

$3.6238025791990193084270042653997y + y - 2.205y = 1500$

Add like terms

$2.4188025791990193084270042653997y \approx 1500$

Divide both sides by 7.012

$y\approx 213.91$ $y\approx620.14$

$\bf \textit{circumference of a circle}\\\\
C=2\pi r\qquad r=radius=\frac{diameter}{2}\\\\
-----------------------------\\\\

\begin{array}{lcccclllll}
&radius&\$&Cmfc&\frac{Cmfc}{\$}\\
&---&---&-----&-----\\
\textit{Baby Bear}&6&10&2\pi \cdot 6&\frac{2\pi \cdot 6}{10}\\\\
\textit{Mama Bear}&8&12.50&2\pi \cdot 8&\frac{2\pi \cdot 8}{12.50}\\\\
\textit{Papa Bear}&
\begin{array}{llll}
diameter=18\\
radius=\frac{18}{2}=9
\end{array}&17&2\pi \cdot 9&\frac{2\pi \cdot 9}{17}
\end{array}$

notice, Papa Bear is 18inches in diameter, but radius is half that

and "edge per dollar" simply means, how much circumference per dollar
or $\bf \cfrac{Cmfc}{\$}$
