If you purchase a DVD player that cost $625 how much sales tax will you pay to the nearest cent if the rate is 7.375%
sergey [27]
We can get the tax pay by multiplying the total cost times the tax rate, and take into account that 7.375% = 7375/100000 that huge denominator comes from adding 100 more zeroes as the decimal places in the tax amount has, so we do have:
(7.375%)(625)
= (<span>7375/100000)(625)
= 46.09
therefore, the 7.375% out of $625 is $46.09</span>

Two possible floor plans for a new bathroom are shown.
Neko [114]

Answer:

Hope it works for u

Step-by-step explanation:

As we have given two shapes bathroom

square and rectangle

Parameter of square= sum of all the sides   ( : In square all sides are equal

Parameter of square= 4*L  = 4*(x+3)       (:L=x+3

similarly,

In rectangle opposites sides  are equal hence

Perimeter of rectangle= 2*length+2*width  ( : length=x+4,width can't be seen clearly so I assume and take it width=x+1  hope this is equal to the width of ur question otherwise do the calculation by ur self).

Perimeter of rectangle= 2*(x+4)+2(x+1)

so now we have to find the value of "x" for which both perimeter are equal, so

perimeter of square= perimeter of rectangle

4*(x+3)=2*(x+4)+2(x+1)  we can also write as

<h2>2(x+3)+2(x+3)=2(x+4)+2(x+1)</h2><h3>This is the linear equation required</h3><h3>now to find value of "x"</h3><h3>simplify both sides, we get</h3><h3>4x+12=4x+10</h3><h2>0≠2 so that not true and also there is no value of "x"</h2>

for which both parameters become equal

<h2>so from my side "b" option is correct</h2>

Please brain-list it if u find it help-full it requires effort!
