Determine the area of the composite figure to the nearest whole number

Nimfa-mama [501]

Check the picture below.

so, let's notice, is really just a 2x20 rectangle with a quarter of a semicircle with a radius of 11.

$\bf \stackrel{\textit{area of a circle}}{A=\pi r^2}~~ \implies A=\pi 11^2\implies A=121\pi \implies \stackrel{\textit{one quarter of that}}{\boxed{A=\cfrac{121\pi }{4}}} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\underline{\textit{area of the figure}}}{\stackrel{\textit{rectangle's area}}{(2\cdot 20)}+\stackrel{\textit{circle's quart's area}}{\cfrac{121\pi }{4}}\qquad \approx \qquad 135.03\implies \stackrel{\textit{rounded up}}{135}}$

Brainliest if you answer my question

kkurt [141]

Answer:

1

Step-by-step explanation:

To find x, set both equations equal to each other.

$\sqrt{x} = \sqrt{5x - 4}$

$( { \sqrt{x} })^{2} = ({ \sqrt{5x - 4} })^{2}$

$x = 5x - 4$

$x - 5x = 5x - 5x - 4$

$- 4x = - 4$

$- 4x \div - 4 = - 4 \div - 4$

$x = 1$

Alan recorded the points he scored on the basketball court in ms2 school yard. What is the mean absolute deviation of his scores

Alecsey [184]

Answer:

The mean absolute deviation is: 7.44

Step-by-step explanation:

Given

$Scores: 98, 78, 84, 75, 91$

Required

The mean absolute deviation

First, calculate the mean

$\bar x = \frac{\sum x}{n}$

$\bar x = \frac{98+78+84+75+91}{5}$

$\bar x = \frac{426}{5}$

$\bar x = 85.2$

The mean absolute deviation (M) is:

$M = \frac{1}{n}\sum|x - \bar x|$

So, we have:

$M = \frac{1}{5}(|98 - 85.2|+|78 - 85.2|+|84 - 85.2|+|75 - 85.2|+|91 - 85.2|)$

$M = \frac{1}{5}(|12.8|+|-7.2|+|-1.2|+|-10.2|+|5.8|)$

Remove absolute brackets

$M = \frac{1}{5}(12.8+7.2+1.2+10.2+5.8)$

$M = \frac{1}{5}*37.2$

$M = 7.44$
