Answer:

She wrote 3 pages per hour

Step-by-step explanation:

12 ÷ 4 is 3

48 ÷ 16 is 3

or add the days and hours

16 + 4 = 20

48 + 12 = 60

60 days /20 hours = 3 pages per hour

12 divided by 2 x the absolute value of 1.3 minus 2.16

yaroslaw [1]

The value of the expression (12/2)×| 1.3 - 2.16 | is 5.16 .

The Absolute Value of a number means writing the number without the negative sign .

For Example : the absolute value of -2 is |-2| = 2

In the question ,

an expression in words is given as "12 divided by 2 x the absolute value of 1.3 minus 2.16 "

the above expression in numbers can be represented by

= (12/2)×| 1.3 - 2.16 |

= 6 × | 1.3 - 2.16 |

= 6 × |-0.86|

= 6 × 0.86 .... because |-0.86| = 0.86

= 5.16

Therefore , The value of the expression (12/2)×| 1.3 - 2.16 | is 5.16 .

The given question is incomplete , the complete question is

Find the value of the expression " 12 divided by 2 x the absolute value of 1.3 minus 2.16 " ?

Find the angles between -pi and pi that satisfy:<br><br> (−√3) sin(v)+cos(v)=√3

MAXImum [283]

Observe that

$\sin\left(\dfrac\pi6-v\right)=\sin\dfrac\pi6\cos v-\cos\dfrac\pi6\sin v=\dfrac12\cos v-\dfrac{\sqrt3}2\sin v$

In the original equation, divide both sides by $\dfrac12$ :

$-\sqrt3\sin v+\cos v=\sqrt3\implies\dfrac12\cos v-\dfrac{\sqrt3}2\sin v=\dfrac{\sqrt3}2$

$\implies\sin\left(\dfrac\pi6-v\right)=\dfrac{\sqrt3}2$

Next,

$\sin x=\dfrac{\sqrt3}2\implies x=\dfrac\pi3+2n\pi,x=\dfrac{2\pi}3+2n\pi$

where $n$ is any integer. Then

$\sin\left(\dfrac\pi6-v\right)\implies v=-\dfrac\pi6-2n\pi,v=-\dfrac\pi2-2n\pi$

Fix $n=0$ to ensure $-\pi$ , so that

$v=-\dfrac\pi6,v=-\dfrac\pi2$
