Taylin buys 5 ounces of tea leaves for $2.35. At this rate, how much money does she need to buy 12 ounces of tea leaves? (second

MissTica

Answer:

see below

Step-by-step explanation:

We can determine how much 12 ounces cost by using ratios

5 ounces 12 ounces

-------------- = -------------------

2.35 x

Using cross products

5x = 12*2.35

5x = 28.2

Divide each side by 5

5x/5 = 28.2/5

x =5.64

If she has 10 dollars

5 ounces y ounces

-------------- = -------------------

2.35 10

5*10 = 2.35y

50 = 2.35y

Divide each side by 2.35

50/2.35 = 2.35y/2.35

21.27659574 =y

She can buy 21.3 ounces

If sin(x)=0.3090 , what is the approximate value of csc(x)?

vitfil [10]

$\sin x=0.3090\approx\dfrac13$

$\csc x=\dfrac1{\sin x}\implies\csc x\approx 3$

which makes 3.2362 likely the best choice.

Colt1911 [192]

Answer:

James has an ice cube tray that makes ice in the shape of spheres rather than cubes. Each sphere of ice has a radius of 2 cm. One tray makes 6 spheres.What is the total volume of ice the tray can make at one time?

Total volume of the tray James have = 201.06 cm^3

Step-by-step explanation:

Given:

Radius of the spherical ice cube = 2 cm

No. of spheres in the ice cube = 6

We have to find the total volume of the ice tray that can make at one time.

Let the total volume be "V".

Formula to be used:

Volume of sphere = $\frac{4\pi r^3 }{3}$ cubic unit.

Total volume = $n\times \frac{4\pi r^3 }{3}$ cubic unit.

So,

Total volume of the ice tray (V) :

⇒ $V=n\times \frac{4\pi r^3 }{3}$

⇒ Plugging n = 6 and r = 2

⇒ $V=6\times \frac{4\pi (2)^3 }{3}$

⇒ $V=6\times \frac{4\pi (8) }{3}$

⇒ $V=6\times \frac{32\pi }{3}$

⇒ $V=\frac{32\times 6\pi }{3}$

⇒ $V=32\times 2\pi$

⇒ $V=201.06\ cm^3$

So,

The total volume of ice the tray can make at one time = 201.06 cm^3
