Answer:

12

b is height for non-right triangles

6*4(1/2)=A

24(1/2)=A

12=A

How find a ratio of the area of a circle and a square

ladessa [460]

Answer:

<u>CIRCLE : CIRCLE</u>

Ratio of area is the scale factor squared. So find the radii of the two circles, square both values, and simplify the ratio.

<u>SQUARE : SQUARE</u>

Ratio of area is the scale factor squared, So find the side lengths of the two squares, square both values, and simplify the ratio.

<u>SQUARE : CIRCLE</u>

Using the formulas A = s*s and A = pi*r^2, find the areas of the circle and the square. Then simplify the ratio.

1 1/4mi = ft, can someone explain this to me

skelet666 [1.2K]

First off, we'll convert the mixed fraction to "improper" and check about, keeping in mind that, there are 5280 feet in 1mile.

$\bf \stackrel{mixed}{1\frac{1}{4}~mi}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}~mi}\\\\
-------------------------------$

$\bf \begin{array}{ccll}
feet&miles\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
5280&1\\
f&\frac{5}{4}
\end{array}\implies \cfrac{5280}{f}=\cfrac{1}{\quad \frac{5}{4}\quad }\implies \cfrac{5280}{f}=\cfrac{\frac{1}{1}}{\quad \frac{5}{4}\quad }
\\\\\\
\cfrac{5280}{f}=\cfrac{1}{1}\cdot \cfrac{4}{5}\implies \cfrac{5280}{f}=\cfrac{4}{5}\implies \cfrac{5280\cdot 5}{4}=f\implies 6600=f$
