Answer:

m∡BOC = 47°

Step-by-step explanation:

A straight angle is 180°, therefore m∡AOC is 180°.

Because of this, the two angles adding up to it, m∡AOB and m∡BOC, adds up to 180°.

So, 6x + 29 + 3x + 124 = 180.

Simplification and subt. POE shows 9x = 27, so x = 3.

Plugging x back into 6x + 29 gives us 47.

ryzh [129]

Answer:

\bold{\frac{8455687800}{113}}

Step-by-step explanation:

\frac{24\times \:128725\left(7\times \:782\right)}{199+4+23}

\mathrm{Add\:the\:numbers:}\:199+4+23=226

=\frac{24\times \:128725\times \:7\times \:782}{226}

\mathrm{Factor\:the\:number:\:}\:24=2\times \:12

=\frac{2\times \:12\times \:128725\times \:7\times \:782}{226}

\mathrm{Factor\:the\:number:\:}\:226=2\times \:113

=\frac{2\times \:12\times \:128725\times \:7\times \:782}{2\times \:113}

\mathrm{Cancel\:the\:common\:factor:}\:2

=\frac{12\times \:128725\times \:7\times \:782}{113}

\mathrm{Multiply\:the\:numbers:}\:12\times \:128725\times \:7\times \:782=8455687800

\bold{=\frac{8455687800}{113}}

Harding and Jack found that 8 percent of their number was 72. What was their number?
Aneli [31]
I do believe that the answer is 900. 
Steps:
I first set up a proportion, with 8/100 and 72/x (x being the number we are trying to find) 
As I was taught, you multiply 100 by 72, which equals 7,200.
Then, I divided 7,200 by 8, which gave me 900.
This is what the proportion process should have looked like:
8/100    72/x
7,200/8
x=900
I hope this helps!
