Answer:

DF^2=DH^2+HF^2

DF=√DH^2+HF^2

DF=√2(DH^2) {AS IT IS A CUBE THEN ALL SIDES ARE EQUAL}

DF=√2*11^2 {ALL SIDES OF A CUBE ARE EQUAL}

DF=√2*121

DF=√242

DF=15.555

Crank

Answer:

C = \frac{963}{92}

Step-by-step explanation:

given A varies directly as B and inversely as C then the equation relating them is

A = \frac{kB}{C} ← k is the constant of variation

to find k use the condition A = 6 , B = 10 , C = 15 , then

6 = \frac{x10k}{15} ( multiply both sides by 15 )

90 = 10k ( divide both sides by 10 )

9 = k

A = \frac{9B}{C} ← equation of variation

when A = 92 and B = 107 , then

92 = \frac{9(107)}{C} ( multiply both sides by C )

92C = 963 ( divide both sides by 92 )

C = \frac{963}{92}
