I would think that the answer is C because her distance is always increasing as long as shes moving, it isn't asking for direction, so no matter if she goes forward then backwards then forwards again she has still traveled that distance, so I believe its C because you can't go negative distance, even if you go backwards

The Volume () of gas vanes inversely to the pressure (P). The volume of gas is 200 cm ^ 3 under pressure of 32 kg/cm^ 2 What wil
WITCHER [35]

Answer:

0.025 Kg/ cm²

Step-by-step explanation:

if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable

the equation that represents inverse proportion :

y = \frac{b}{x}

where b = constant of proportionality

to determine the answer in this question :

1. determine constant of proportionality

200 = k / 32

k = 6400

2. Determine the amount of pressure using the constant of proportionality

256, 000 = 6400 / pressure

pressure = 6400 / 256, 000 = 0.025

Megan is checking her tax bill for the last year.
steposvetlana [31]

Answer:

£53205

Step-by-step explanation:

The computation is shown below:

£11,000  = $0

In excess of  £11,000  and up to  £43,000 the tax rate is 20%

So the tax amount is

=  (£43,000 -  £11,000) × 20%

=  £6,400

In excess of   £43,000 and up to  £150,000 the tax rate is 40%

So the tax amount is

= (£150,000 - £43,000) × 40%

=  £42,800

And, the remaining amount is

=  (£158,900 -  £150,000) × 45%

=  £4,005

So the total tax paid amount is

=  £0 +  £6,400 +  £42,800 +  £4,005

=  £53,205
