marge has three times as many figurines as janet. if marge has 87 figurines, how many does janet have?

Vlad [161]

Answer:

The total number of figurines Janet has = 29

Step-by-step explanation:

Let the number of figurines Janet has = m

So, the Number of figurines marge has

= 3 x (Number of figurines Janet has)

or, Marge has 3 x m figurines.

Also, We are given that Marge has 87 figurines.

⇒ 3 x m = 87

or, $m = \frac{87}{3} = 29$

or, m = 29

Hence, the total number of figurines Janet has = m = 29

A box with a square base and open top must have a volume of 32,000 cm3. Find the dimensions of the box that minimize the amount

nata0808 [166]

Answer:

Step-by-step explanation:

Given

Volume of box $V=32,000 cm^3$

Let b be the square base and h be the height of box

Volume $V=b^2\cdot h$

$h=\frac{V}{b^2}$

Surface Area $A=b^2+4bh$

$A=b^2+4b\times \frac{V}{b^2}$

$A=b^2+4\frac{V}{b}$

Differentiate A w.r.t b to get maxima/minima

$\frac{\mathrm{d} A}{\mathrm{d} b}=2b-\frac{4\times V}{b^2}$

$2b-\frac{4\times V}{b^2}=0$

$b^3=\frac{4V}{2}$

$b^3=\frac{4\times 32,000}{2}$

$b=40 cm$

$[tex]h=\frac{32,000}{40\times 40}$

$h=20 cm$

Terry is filling spherical water balloons with a faucet that puts out 100cm^3 of water per second. At that rate, it takes Terry

ioda

Answer:

To the nearest centimeter

Radius= 5 cm

Step-by-step explanation:

Rate of filling balloon= 100cm³/s

Time to feel the balloon= 6 s

Volume of the filed balloon

= Rate*time

= 100*6

= 600 cm³

Volume of balloon= 4/3πr³

Volume of balloon=600cm³

600= 4/3πr³

(600*3)/4π= r³

1800/4π= r³

450/π= r³

143.239 = r³

5.232= r

To the nearest centimeter

Radius= 5 cm
