She can get $12. X= ($42)(2/7)
The answer is c bc adjacent angles that are side by side and share one segment
1/8 inch thick
inner diameter of 8.5
volume shell=volume total-volume shell
1/8=0.125
diameter/2=radius
radius inner=8.5/2=4.25
radiustotal=inner+outer=4.25+0.125=4.375
so
Vouter-Vinner=(4/3)pi4.375³-(4/3)pi4.25³
Vshell=(4/3)(pi)(4.375³-4.25)
Vshell=(4/3)(pi)(83.740234375-76.765625)
Vshell=(4/3)(pi)(6.974609375)
Vshell=9.299479166666666666666pi cubic inches
Vshell≈16.433536180619 cubic inches
Ok so
sale is 15% off
and add 6% tax
100-15=85
100+6=106
therefor
1250 with 15% discount plus 6% tax means
1250 times 85% times 106% =
1250 times 0.85 times 1.06=1126.25
final cost=$1126.25
<span>a.
</span>Let m = be the number of miles driven
Cost of NYC rentals: 525 + 0.21m
Cost of Metro Trucks: 585 + 0.13m
<span>b.
</span>525 + 0.21m = 850
0.21m = 325
M = 1,548 miles
<span>c.
</span>Initial cost for NYC rentals = $525
Initial cost for Metro Trucks = $585
<span>d.
</span>NYC rentals: 525 + 0.21 (500) = $630
Metro Trucks rentals: 585 + 0.13 (500) = $650
<span>e.
</span>525 + 0.21m = 585 + 0.13m
0.21m – 0.13m = 585 – 525
0.08m = 60
m = 750 miles
