Answer:
8.6 in²
Step-by-step explanation:
The area of the entire circle is A = πr², or A = π(2 in)².
This corresponds to a central angle of 2π radians, or 6.28 radians.
The area of the sector described above is just a certain fraction of that:
4.3 rad
-------------- * Area of circle = 0.685(4 * 3.14) = 8.6 in²
6.28 rad
Hi!
<h3>We need to isolate x on one sides, and whatever we do to the equation we have to do on both sides. </h3><h3>Subtract 5 from both sides. </h3>
4x + 5 - 5 = 12 - 5 - 7x
4x = 7 - 7x
<h3>Add 7x to both sides. </h3>
4x + 7x = 7 - 7x + 7x
11x = 7
<h3>Divide by 11 on both sides</h3>
11x/11 = 7/11
<u>x = 7/11</u>
<h2>The answer is x = 7/11</h2>
Hope this helps! :)

The answer is: "100" .

Explanation:
__________________________
Looking at the ENTIRE EQUATION (all numeric values on BOTH sides of the equation), we can see that the decimal that with the most decimal places goes to the right, to the hundredths place (i.e. two places); so by multiplying the ENTIRE EQUATION (BOTH SIDES—i.e. EACH term on EACH SIDE) by "100", we get rid of ALL the decimals, as follows:
_________________________________________
100* {<span>5.6j – 0.12 = 41.1 j ) ;
</span>↔ (100* 5.6j) – (100 * 0.12) = (100 * 41.1 j );
↔ 560 j – 12 = 4110 j ;

Answer:
A . $46
Step-by-step explanation:
because 575 - 8% = 529
529 + 49 = 575
