8 0

Step-by-step explanation:

m(arc AD) = m \angle ARD \\  = 105°\\\\m(arc BD) = m \angle BRD  \\ = 50°+ 35° \\ = 85°\\\\m(arc ADB) = 105°+50°+ 35° \\ = 190°\\\\m(arc ABC) = 360°-(105°+50°) \\ = 360°-155° \\ = 205°\\\\ \\

Which number can each term of the equation be multiplied by to eliminate the decimals before solving?
Sati [7]
Ok...

5.6 = 56/10 = 560/100

1.1 = 11/10 = 110/100

0.12 = 12/100

--------------

\frac { 560 }{ 100 } j-\frac { 12 }{ 100 } =4+\frac { 110 }{ 100 } j\\ \\ \\ 100\times \left( \frac { 560 }{ 100 } j-\frac { 12 }{ 100 }  \right) =\left( 4+\frac { 110 }{ 100 } j \right) \times 100\\ \\ 560j-12=400+110j\\ \\ 560j-110j=400+12\\ \\ 450j=412\\ \\ j=\frac { 412 }{ 450 }

So, the answer is: 100

You could multiply both sides of the equation by 100 to get the value of (j) quickly.

Svetach [21]

Answer:

Step-by-step explanation:

(i)

y=k*x^2\\\\if\ x=3, y=18 ==> 18=k*9\ ==> k=2\\\\Equation\ is:\ y=2x^2\\

(ii)

x=5 ==> y=2*5²=50

(iii)

32=2*x^2\\x^2=16\\x^2-4^2=0\\(x-4)(x+4)=0\\\\x=4\ or\ x=-4\\

Is 3.02859 is rational
Solnce55 [7]
When we say a rational number, this is a number that can be <span>written as a ratio. That means it can be written as a fraction, both the numerator and denominator whole numbers. Based on the given value above, I believe that the answer is considered as a rational number because it can be written as a fraction: 3 and 29/100. Hope this answer helps.</span>
