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 = 8Your number is:
sixDone
I hope that
helps!

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.
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
