Step-by-step explanation:

the volume of a box (or prism) is always

length × width × height

so, box A

13 × 12 × 16 = 2,496 in³

box B

18 × 25 × 16 = 7,200 in³

box C

12 × 14 × 22 = 3,696 in³

box D

20 × 22 × 17 = 7,480 in³

so, she can use B or D.

vredina [299]

By the law of sines,

\dfrac{\sin90^\circ}{17}=\dfrac{\sin y^\circ}9

\implies\sin y^\circ=\dfrac9{17}

(since \sin90^\circ=1)

\implies y=\sin^{-1}\left(\dfrac9{17}\right)\approx32.0

The Big Telescope Company sells circular mirrors. Their largest mirrors have radii of 5 meters and their smallest mirrors have r
pogonyaev

Answer: 1:5

Step-by-step explanation:

Given: The cost of every mirror is proportional to the cube of the mirror's radius.

i.e. \dfrac{\text{Cost of smallest mirror}}{\text{Cost of largest mirror}}=\dfrac{(\text{radii of smallest mirror}^3)}{\text{(radii of largest mirror)}^3}

Their largest mirrors have radii of 5 meters and their smallest mirrors have radii of 1 meter.

Then,

\dfrac{\text{Cost of smallest mirror}}{\text{Cost of  largest mirror}}=\dfrac{1^3}{(5)^3}=\dfrac{1}{125}

The ratio of the total cost of 25 of the company's smallest mirrors to the cost of one of the company's largest mirrors will be:

\dfrac{\text{Cost of 25 smallest mirror}}{\text{Cost of largest mirror}}=\dfrac{25\times 1}{125}=\dfrac{1}{5}

Hence, the ratio of the total cost of 25 of the company's smallest mirrors to the cost of one of the company's largest mirrors = 1:5 .
