Please help me with this I’ll make you as brainlist
Arlecino [84]

Answer:

x = 3\sqrt{13} = 10.8

Step-by-step explanation:

Both problems are done the same way.  I will do the first one and you do the second one.  OK?

Move the radius x to make a right triangle.  The 6 unit segment bisects the chord.  So, the legs of the right triangle are 6 and 9

The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle.   Now,

6^{2}  + 9^{2}  = x^{2}

x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}= 10.8

None of the answer choices are to the nearest tenth.  So, I am confused about that.

In  the second problem, the answer should be 11.2

Mike's monthly pay after taxes is $2,300.
wlad13 [49]

Step-by-step explanation:

100%=>$2,300

45%=>x

x=$2,300×45÷100=$1035

The pay left for other purposes

$2300-$1035=$1265

Or:

100%=>$2,300

55%=>x

x=$2,300×55÷100=$1265.
