Step-by-step explanation:
an object and its shadow create a right-angled triangle.
2 objects and their shadows create 2 similar right-angled triangles.
that means the angles are the same, and the side lengths of one triangle all correlate with the corresponding side lengths of the other triangle via the same factor.
so,
42 × f = 6
f = 6/42 = 1/7
the length of Joel's shadow is then
20 × f = 20 × 1/7 = 2.857142857... ft
He made $ 394.90 because you need to add all the large paintings then the small ones then add them all
The solutions are .
Solution:
Given equation:
Add on both sides.
-------- (1)
(given) -------- (2)
Equate (1) and (2).
Add on both sides.
Add 5 on both sides.
Divide by 5 on both sides, we get
Taking square root on both sides, we get
Substitute in (1).
Substitute in (1).
Therefore the solutions are .
