Answer:

1727 inches or approximately 143.91667 feet

Step-by-step explanation:

circumfrence is the $diameter*\pi$ so its $3.14*22 inches$ . this gives you a circumfrence of 69.08 inches which is eaual to one revolution. you simply have to do $69.08*25=1727$ inches. I didnt know if you also needed the answer in feet, so i divided that by 12 to get an approxamation of 143.91667 feet (it comes out with a repeating 6, so i rounded it to 7 on the third to six be accurate).

Solve the simultaneous equations C^2+d^2=5 and 3c+4d=2

Naily [24]

If 3c+4d=2 then c=(2-4d)/3
And if you put that into the other equation
${\frac{2 - 4d}{3}}^{2} + {d}^{2} = 5$
Then you multiply everything by 3, getting

${(2 - 4d)}^{2} + 3 {d}^{2} = 15$
And then

$2 - 4d + \sqrt{3} d = \sqrt{15}$
Leaving
$d( \sqrt{3} - 4) = \sqrt{15} - 2$
I dont have a calc with me right now but you just pot this into the calculator:
$d = \frac{ \sqrt{15} - 2 }{ \sqrt{3} - 4}$
And when you get the number you insert it into the nest eqation to get c

$c = \frac{2 - 4d}{3}$
So basically

$c = \frac{2 - 4 \frac{ \sqrt{15} - 2}{ \sqrt{3} - 4} }{3}$

The gas tank of a 2015 Nissan Sentra holds 13.2 gallons. How many pounds of carbon dioxide are produced by burning an entire tan

OLEGan [10]

<span>13.2 gallons=49.9 liters
the gas is the octan C8H18
the combustion of Octan equation is
C8H18 + 25/2 O2-------------------> 8CO2 + 9 H2O
1mole 8 moles
n(C8H18)=a n(CO2)=b
so
1 mole/a = 8moles /b
and b= 8molesx a

we must find the value of a, molar volume of a gas is v= 22.4l/mol=V/a, so a=V/v= 49.9/22.4= 2.23 moles

and b=8 x a=8x 2.23=17.85 moles
M(CO2)=m(CO2)/n(CO2)====> m=n x M=17.85 * (12+2x16)= 785.4 g

m(CO2)=785.4g = 1.57 pound</span>
