Alik [6]

Solution:

Let the bottle of sunscreen cost be $x. Then we can write

($x+ $6.50)+6%($x+ $6.50)=$16.43

Now solve this for x as below

$($x+ $6.50)+\frac{6}{100}($x+ $6.50)=$16.43\\$

$\frac{100x+650+6x+39}{100}=16.43\\
\\
106x+689=1643\\
\\
106x=1643-689\\
\\
106x= 954\\
\\
x=9\\$

Hence the bottle of sunscreen cost $9.

AB and DE are chords that intersect at point F inside circle C as shown. If the measure of arc EA= 50 degrees and the measure of

defon

Answer:

Part 1) $m\angle AFE=55^o$

Part 2) $m\angle EFB=125^o$

Step-by-step explanation:

Part 1) what is the measure of angle AFE

we know that

The measure of the interior angle is the semisum of the arches that comprise it and its opposite.

<u>Note:</u> In this problem the correct measure of arc EA is 40 degrees (see the picture)

$m\angle AFE=\frac{1}{2}(arc\ EA+arc\ DB)$

substitute the given values

$m\angle AFE=\frac{1}{2}(40^o+70^o)=55^o$

Part 2) what is the measure of angle EFB?

we know that

$m\angle AFE+m\angle EFB=180^o$ ---> by supplementary angles (form a linear pair)

substitute the given value

$55^o+m\angle EFB=180^o$

$m\angle EFB=180^o-55^o=125^o$

What is the distance between (-5,5) and (2,6) rounding to the nearest hundred

ExtremeBDS [4]

$\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ -5}}\quad ,&{{ 5}})\quad 
% (c,d)
&({{ 2}}\quad ,&{{ 6}})
\end{array}\qquad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
d=\sqrt{[2-(-5)]^2+[6-5]^2}\implies d=\sqrt{(2+5)^2+(6-5)^2}
\\\\\\
d=\sqrt{7^2+1^2}\implies d=\sqrt{50}$
