Suppose that y is directly proportional to x and that y = 10 when x = 3. Complete parts (a) and (b). (a) Find the constant of pr

Yuliya22 [10]

For this case we have that if "y" varies directly with "x", then it is true that:

$y = kx$

Where:

k: It is the constant of proportionality

We have according to the data that:

$10 = k (3)$

We find the value of "k":

$k = \frac {10} {3}$

Having "k", we find "y" when $x = 6$ :

$y = \frac {10} {3} (6)\\y = \frac {60} {3}\\y = 20$

ANswer:

$k = \frac {10} {3}\\y = 20$

A soccer ball made of leather 1/81/8 in thick has an inner diameter of 8.58.5 in . Use the formula V=(4/3)πr3V=(4/3)πr3 to calcu

Sphinxa [80]

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
