Saqui buys streamers for \$0.09$0.09dollar sign, 0, point, 09 per meter.
Colt1911 [192]

Answer:

$0.27

Step-by-step explanation:

1/4 The ratio of meters of streamers to cost of streamers is 1 : 0.09

     We want to know the ratio of centimeters of streamers to cost of  
     streamers.

2/4 We need to convert meters to centimeters.

      There are 100 centimeters in 1 meter.

      So, if 1 meter of streamers costs $0.09, then 100 centimeters of
      streamers also cost $0.09.

3/4 The ratio centimeters of streamers to cost for 300 centimeters of
      streamers.

      Now, we can find an equivalent ratio to find the cost for 300
      centimeters of streamers.

4/4 The streamers cost $0.27 per 300 centimeters.

A sculpture of a gaint cube contains 1000 cubes within it. How many smaller cubes are along each edge of the sculpture
uranmaximum [27]

<u>ANSWER: </u>

A sculpture of a giant cube contains 1000 cubes within it .Along side of each edge of a giant cube there are 10 small cubes.

<u>SOLUTION</u>:  

Given that a giant cube has 1000 cubes in it.

Let , length of the giant cube be L

Length of each small cube be v

Then, volume of giant cube = \mathrm{L}^{3}

Volume of small cube = v^{3}

According to the given problem, Volume of giant cube must be equal to 1000 small cubes volume.

\mathrm{L}^{3}=1000 \mathrm{v}^{3}

Apply cube root on both sides

\sqrt[3]{L^{3}}=\sqrt[3]{1000 \times v^{3}}

\sqrt[3]{L^{3}}=\sqrt[3]{(10 v)^{3}}

\sqrt[3]{L^{3}} = \sqrt[3]{(10 v)^{3}}

\mathrm{L}=10v

From above equation we can say that along side of each edge of a giant cube there are 10 small cubes.

Solve and check the answers in the original equation
Scrat [10]
 12 + 5k + 15                     -24
------------------- =  -----------------------
      k + 3                      k - 4
 5k + 27              -24
------------ =  ---------------
  k + 3                k - 4

 (k - 4)(5k + 27) = -24 (k + 3)
5k^2 - 20k + 27k -108 = - 24k - 72
5k^2 + 31k - 36 = 0
(5k + 36)(k - 1) = 0

5k + 36 = 0; k = -36/5 = -7.2
k - 1 = 0; k = 1

solutions
k = 1 and k = -7.2
