Area of circle =πr²

πr²=615.75
r²= 615.75*7/22

r=²√196 =14

diameter =2r=2*12 =28

Part c
ehidna [41]

The probability that the first slice of the cake will have the marble exists

7/66.

<h3>How to determine the probability using parts A and B?</h3>

Part A of the question demands that the volume of the cake be

estimated.

The volume of the cake exists, $V=\pi(\frac{d}{2} )^{2} h \\

$&V=\pi(\frac{9}{2} )^{2} * 4

$V=81 \pi

The part B of the question requires that the volume of each cut be

computed

The volume of each cut exists, V = 27

To estimate the required probability

We simply divide the volume of each cut by the volume of the cake.

$P=\frac{27}{81 \pi}

$P=\frac{1}{3 \pi}

Expand $\pi$

$&P=\frac{7}{3 * 22} \\

$&P=\frac{7}{66}

Therefore, the probability that the first slice of the cake will contain the

marble exists at 7/66.

4m-3n=8; solve for m
Ierofanga [76]
4m - 3n = 8

Add 3n to both sides.

4m = 3n + 8

Divide both sides by 4.

m = 3/4n + 2

So, m = 3/4n + 2

However, if you made a typo, and meant 3m instead of 3n, your answer would be :

4m - 3n = 8

n = 8

~Hope I helped!~

Answer:

a). Mileage for carA= \frac{2}{x}  , and mileage for carB=\frac{ 3x+2}{x(x+1)}

b).total mileage for both is similar to average of them= \frac{(mileageA + mileageB)}{2}

=\frac{5x+4}{2x(x+1)}[tex]mil/gal

Step-by-step explanation:

It is given that the distance traveled by car A=2x+2=2(x+1)

And distance traveled by car B= 3x+2

We know the mileage is mile/gallon,

a).So mileage of car A= \frac{distance traveled by car A}{gallos of fuel used}

=\frac{2x+2}{x^2 +x}\\ =\frac{2(x+1)}{x(x+1)} \\=\frac{2}{x}mil/gal

Similarly , the mileage for car B= \frac{distance traveled by car A}{gallons of fuel used}

=\frac{3x+2}{x^2+x} \\=\frac{3x+2}{x(x+1)}mil/gal

b).total mileage for both is similar to average of them= \frac{(mileageA + mileageB)}{2}

=\frac{2x+2}{x(x+1)}+\frac{3x+2}{x(x+1)}\\ =\frac{2x+2+3x+2}{x(x+1)}\\=\frac{5x+4}{x(x+1)}mil/gal

Now divide by 2 for total(average) mileage.

\frac{\frac{5x+4}{x(x+1)} }{2}\\ =\frac{5x+4}{2x(x+1)} mil/gal.

Thus those are the answers.
