A rectangular prism has a width of 51 ft and a volume of 144 ft3. Find the volume of a similar prism with a width of 17 ft. Roun

meriva

Answer:

$5.3\ ft^3$

Step-by-step explanation:

Similar shapes with scale factor $k$ have proportional volumes with coefficient $k^3$ i.e.

$\dfrac{V_{large}}{V_{small}}=k^3,$

where

$k=\dfrac{\text{width of large prism}}{\text{width of small prism}}.$

Since

$\text{width of large prism}=51\ ft,\\ \\\text{width of small prism}=17\ ft,$

then

$k=\dfrac{51}{17}=3.$

Hence,

$\dfrac{144}{V_{small}}=3^3\Rightarrow V_{small}=\dfrac{144}{27}=\dfrac{16}{3}=5\dfrac{1}{3}\approx 5.3\ ft^3.$

sergeinik [125]

Answer

Find out the what is the clearance price of a manatee.

To prove

As given

The gift shop at manatee mall was having a clearance sale.

Everything was marked down 30%.

The original price of a manatee hat was $12.

30 % is written in the decimal form.

$= \frac{30}{100}$

= 0.30

30% of the original price of a manatee = 0.30 × 12

= $ 3.6

Clearance price = original price - 30% of the original price

= 12 - 3.6

= $ 8.4

Therefore the clearance price be $8.4 .

A dilation has center (0, 0). Find the image of each point for the given scale factor.

pshichka [43]

Answer:

A. (−3,5)

Step-by-step explanation:

The rule for dilation by scale factor k is given by:

$(x,y)\to (kx,ky)$

The given point is P(-3,5) and the scale factor is k=1

We substitute the point and the scale factor into the rule to get:

$P(-3,5)\to P'(-3\times1,5\times1)$

This gives us:

$P(-3,5)\to P'(-3,5)$

The correct answer is A
