Bogdan [553]

Answer:1 and 2

Step-by-step explanation:

Given

Volume needed $V=220\ in.^3$

For first cylinder

$r=3\ in.$

$h=4\ in.$

$V=\pi r^2h$

$V_1=\pi (3)^2(4)$

$V_1=113.11\ in^3$

For second cylinder

$r=4\ in.$

$h=4\ in.$

$V=\pi r^2h$

$V_2=\pi (4)^2(4)$

$V_2=201.08\ in^3$

For Third cylinder

$r=9\ in.$

$h=9\ in.$

$V=\pi r^2h$

$V_3=\pi (9)^2(9)$

$V_3=2290.51\ in^3$

For fourth cylinder

$r=4\ in.$

$h=9\ in.$

$V=\pi r^2h$

$V_4=\pi (4)^2(9)$

$V_4=452.448\ in^3$

So, cylinder $1$ and $2$ are appropriate as it is under $220\ in.^3$

Masha had 200 scoops of ice cream and Liz had 180 scoops. After they each ate an equal amount of scoops, the ratio of Masha’s sc

kherson [118]

Answer:

Each of them eat 140 scoops.

Step-by-step explanation:

Let x be the amount eaten by each of them,

Given,

The initial ice cream Masha has = 200 scoops

Final ice cream Masha has = ( 200 - x ) scoops

while the initial ice cream Liz has = 180 scoops,

Final ice cream Liz has = (180-x) scoops,

According to the question,

$\frac{200-x}{180-x}=\frac{3}{2}$

$400-2x=540-3x$ ( by cross multiplication )

$-2x=140-3x$ ( Subtracting 400 on both sides )

$x=140$ ( adding 3x on both sides )

Hence, each of them eat 140 scoops.

Inverse equation t=120r/r+120 R=???

Komok [63]

9514 1404 393

Answer:

r = 120t/(120-t)

Step-by-step explanation:

Multiply by the denominator, isolate r terms, then divide by the coefficient of r.

$t=\dfrac{120r}{r+120}\qquad\text{given}\\\\t(r+120)=120r\qquad\text{multiply by $(r+120)$}\\\\120t=120r-tr\qquad\text{subtract $tr$}\\\\\dfrac{120t}{120-t}=r\qquad\text{divide by the coefficient of $r$}\\\\\boxed{r=\dfrac{120t}{120-t}}$
