T varies inversely with the cube of W

$T = k/W^3$

$\frac{1}{9} = k/3^3$

$k = \dfrac{3^3}{9} = 3$

$W^3 = k/T$

$W = \sqrt[3]{ k/T }$

When $T=1/243$

$W = \sqrt[3]{ 3/(1/243)}= \sqrt[3]{729} = 9$

Two angles in a triangle measure 102 degrees and 67 degrees. What is the measure of the third angle?

Nat2105 [25]

Answer:

11 degrees

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees.

From 180 degrees we subtract the sum of 102 degrees and 67 degrees, obtaining 11 degrees (first answer choice)

Decide whether the expression has been simplified correctly.

Alexeev081 [22]

Answer:

No.

Step-by-step explanation:

According to the law of exponent:-

$\displaystyle \large{( \frac{a}{b}) ^{m} = \frac{ {a}^{m} }{ {b}^{m} } }$

Therefore:-

$\displaystyle \large{( \frac{a}{4} )^{5} = \frac{ {a}^{5} }{ {4}^{5} } }$

Ms.Tao flies roundtrip twice yearly between Jacksonville and Los Angeles on business the distance between the two cites is 2,150

vlabodo [156]

2,150 estimated would be 2,000. Since she flies there and back multiply 2,000 by 2. Since she flies it twice multiply 4,000 by 2. Estimated: 8,000 miles. To find the exact miles Do the same thing but with 2,150: 2,150 times 2 = 4,300. 4,300 times 2 = 8,600. She flies exactly 8,600 miles per year :)
