Let the number is m

then:
<span>one-sixth of a number = 1/6 m = m/6

and:
</span><span>sum of one-sixth of a number and negative two = m/6 - 2

and:
</span>sum of one-sixth of a number and negative two is equal to negative two-thirds : m/6 - 2 = -2/3


solving for m:
m/6 - 2 = -2/3
m/6 = -2/3 + 2

m/6 = 4/3                  *6
m = 8

Your number is: six



Done

I hope that helps!

LuckyWell [14K]

The bird flew 5.45m far from the tree.

Step-by-step explanation:

Given,

Sin70° = 0.94

Cos70° = 0.34

Angle of flight = 70°

Refer the diagram attached for better understanding.

Cos70° = (adjacent side) / (hypotenuse)

0.34 = 2/ hyp

hyp = 2/(0.34)

hyp = 5.8 m

We have to find the opposite side of the angle of flight for the distance the bird flew.

Sin70° = (opposite side) /(hypotenuse)

0.94 = (opposite side) / 5.8

Opposite side= 0.94 x 5.8

= 5.45m

The bird flew 5.45m away from the tree to another tree.

zhenek [66]

Answer:

f1: 0.440, f2: 0.931, f3: 1.519

Step-by-step explanation:

To solve the system of equations we need to use the inverse of matrix A, as follows:

A x F = C

A^-1 x A x F = A^-1 x C

I x F = A^-1 x C

where I is the identity matrix.

The inverse of A is:

          1.450 -0.392 -0.090

A^-1 = -0.074 -0.022 0.1536

         -0.406 0.7122 -0.060

(computed with Excel)

The multiplication between the inverse of A and C gives:

                0.440

A^-1 x C = 0.931

                1.519

(computed with Excel)
