Ane goes to a juice bar with her friend neil. she is thinking of ordering her favorite drink, 7/8 orange juice and 1/8 cranberry

juice, but the drink is not on the menu, so she decides to order a glass of orange juice and a glass of cranberry juice and do the mixing herself. the drinks come in two identical tall glasses; to avoid spilling while mixing the two juices, jane shows neil something she learned that day in class. she drinks about 1/8 of the orange juice, then takes the straw from the glass containing cranberry juice, sucks up just enough cranberry juice to fill the straw, and while covering the top of the straw with her thumb, carefully bends the straw and places the end over the orange juice glass. after she releases her thumb, the cranberry juice flows through the straw into the orange juice glass. jane has successfully designed a siphon. assume that the glass containing cranberry juice has a very large diameter with respect to the diameter of the straw and that the cross-sectional area of the straw is the same at all points. let the atmospheric pressure be pa and assume that the cranberry juice has negligible viscosity.

Ludmilka [50]

Answer:

Jaw saw an average of 6 birds each day

Step-by-step explanation:

Given: One day, Jean saw 7 birds. The next day, she  saw 11 birds. The next day, she saw no birds.

To find: average number  of birds Jean saw each day

Solution:

Average is a central value of a set of terms.

Average of terms x_1,x_2,x_3,...,x_n is given by \frac{x_1+x_2+x_3+...+x_n}{n}

Number of birds, Jean saw on day one (x_1) = 7

Number of birds, Jean saw on the second one (x_2)  = 7

Number of birds, Jean saw on the third one (x_3) = 7

So,

average number  of birds Jean saw each day = \frac{x_1+x_2+x_3}{3} =\frac{7+11+0}{3}=\frac{18}{3}=6

Therefore,

Jaw saw an average of 6 birds each day

A cylindrical can without a top is made to contain 25 3 cm of liquid. What are the dimensions of the can that will minimize the
Basile [38]

Answer:

Therefore the radius of the can is 1.71 cm and height of the can is 2.72 cm.

Step-by-step explanation:

Given that, the volume of cylindrical can with out top is 25 cm³.

Consider the height of the can be h and radius be r.

The volume of the can is V= \pi r^2h

According to the problem,

\pi r^2 h=25

\Rightarrow h=\frac{25}{\pi r^2}

The surface area of the base of the can is = \pi r^2

The metal for the bottom will cost $2.00 per cm²

The metal cost for the base is =$(2.00× \pi r^2)

The lateral surface area of the can is = 2\pi rh

The metal for the side will cost $1.25 per cm²

The metal cost for the base is =$(1.25× 2\pi rh)

                                                 =\$2.5 \pi r h

Total cost of metal is C= 2.00 \pi r^2+2.5 \pi r h

Putting h=\frac{25}{\pi r^2}

\therefore C=2\pi r^2+2.5 \pi r \times \frac{25}{\pi r^2}

\Rightarrow C=2\pi r^2+ \frac{62.5}{ r}

Differentiating with respect to r

C'=4\pi r- \frac{62.5}{ r^2}

Again differentiating with respect to r

C''=4\pi + \frac{125}{ r^3}

To find the minimize cost, we set C'=0

4\pi r- \frac{62.5}{ r^2}=0

\Rightarrow 4\pi r=\frac{62.5}{ r^2}

\Rightarrow  r^3=\frac{62.5}{ 4\pi}

⇒r=1.71

Now,

\left C''\right|_{x=1.71}=4\pi +\frac{125}{1.71^3}>0

When r=1.71 cm, the metal cost will be minimum.

Therefore,

h=\frac{25}{\pi\times 1.71^2}

⇒h=2.72 cm

Therefore the radius of the can is 1.71 cm and height of the can is 2.72 cm.
