PV=nRT  since we are only using P,V, and T we have the relationship

PV=T then PV/T=k now we can compare the two conditions...

0.114V/1.6=0.918(116.9)/56.3

V=(1.6*0.918*116.9)/(56.3*0.114)

V≈26.75 L

Karen Sullivan delivers newspapers for the Tribune dispatch. She receives 18.2 cents per paper, six days a week (for the daily p
mario62 [17]

Answer:

About $241.11

Step-by-step explanation:

So, Karen receives 18.2 cents per paper.

She delivers 124 paper per day.

In other words, on days other than Sunday, she will make a total of:

18.2(124)=2256.8\text{ cents}

On Sunday, each paper is sold for $0.70 or 70 cents. She also sells 151 Sunday papers. Thus, on a Sunday, she will make a total of:

70(151)=10570\text{ cents}

Therefore, in one week, she will do the first equation six times and the Sunday equation once. Thus, her total pay will be:

6(2256.8)+10570=24110.8\text{ cents}\approx\$241.11

WILL BE MARKED AS BRAINLIEST !!! <br> Solve<br> (−22 −4 + 8)+ (52 + 2 − 25)
anygoal [31]

Answer:

11

Step-by-step explanation:

1) lets get rid of the parentheses, we dont really need them:

−22 −4 + 8+ 52 + 2 − 25

Following order of operations we need to work from left to right

so

-22-4=-26

-26+8=-18

-18+52=34

34+2=36

36-25=11

the answer is 11

hope this helps

If a projectile is modeled by a parabola, what could the x-intercepts represent?
Mars2501 [29]

Answer: The x-intercepts represents the points at which the parabola crosses the axis of x.

Step-by-step explanation:

If it exist then the x-intercepts represent the zeros,  roots, or quadratic function, the values of x at  y = 0. Then the  parabola does not cross the x-axis, so it has no zeros.

Trig: Which complex number's graph is shown?
Andrei [34K]

ANSWER

2 \sqrt{2} ( \cos( \frac{7\pi}{4}   + i  \sin(  \frac{7\pi}{4} ) )

EXPLANATION

The complex number shown has coordinates (2,-2)

or

z = 2 - 2i

The modulus is

|z|  =  \sqrt{ {2}^{2}  +  {( - 2)}^{2} }

|z|  =  \sqrt{ 8} = 2 \sqrt{2}

The argument is

\theta= \tan^{ - 1} ( \frac{ - 2}{2} )

\theta= \tan^{ - 1} ( -1) =  \frac{7\pi}{4}

The polar form is

2 \sqrt{2} ( \cos( \frac{7\pi}{4}   + i  \sin(  \frac{7\pi}{4} ) )

The first option is correct.
