Answer:

c = ± \sqrt{\frac{d+dt^2}{t^2-3} }

Step-by-step explanation:

Given

t = \sqrt{\frac{3c^2+d}{c^2-d} } ( square both sides )

t² = \frac{3c^2+d}{c^2-d} ( multiply both sides by c² - d )

t²(c² - d) = 3c² + d ← distribute left side

t²c² - dt² = 3c² + d ( subtract 3c² from both sides )

t²c² - 3c² - dt² = d ( add dt² to both sides )

t²c² - 3c² = d +dt² ← factor out c² from each term on the left side

c²(t² - 3) = d + dt² ( divide both sides by t² - 3 )

c² = \frac{d+dt^2}{t^2-3} ( take the square root of both sides )

c = ± \sqrt{\frac{d+dt^2}{t^2-3} }

Rama09 [41]
205.2 square feet

Convert 90% to a decimal. You get .9 Multiply 228 by .9 to find what 90% of 228 is. You should get 205.2.

Janelle has a 12-ounce can of soft drink. She drinks 3/5 of the soft drink.
guapka [62]

Answer:

Answer:  4.8 ounces

Step-by-step explanation:

In total there are 12 ounces. If she drinks 3/5 of 12 you multiply 3/5 by 12.

3/5 * 12 would be equal to 3/5 * 12/1 which is 36/5. You have found how much she has drank. 36/5 is also equal to 7.2 ounces. Subtract 7.2 form 12 and you get 4.8 ounces.

Hope this helped!

The ratio of the sides EF/LM after the transformation is 1/8

<h3>Transformation</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>rotation, translation, reflection and dilation.</em>

Dilation is the increase or decrease in size of a figure by a factor while translation is the movement of a point up, down, left or right.

Given the tansformation:

  • (x,y) → (8x, 8y) → (x - 4, y - 4).
  • This means a dilation of CDEF by 8 and translated 4 units down and 4 units left.

Hence:

LM = 8 * EF

EF/LM = 1/8

The ratio of the sides EF/LM after the transformation is 1/8
