Answer:
40.1
Step-by-step explanation:
Step-by-step explanation:
an object and its shadow create a right-angled triangle.
2 objects and their shadows at the same time create therefore two similar right-angled triangular
triangles.
that means the angles are the same, and each side length of one triangle correlates to the corresponding side length of the other triangle by the same factor.
so, when we know the factor of one pair of sides, we can calculate the lengths of the others by using the same factor.
therefore,
1.57 × f = 50.5
f = 50.5 / 1.57 = 32.1656051...
the height of the tower is then
3.1 × f = 3.1 × 32.1656051... = 99.7133758... m ≈ 100 m
Answer:
f = 6y + 3
Step-by-step explanation:
<u>The equation to reflect this condition is:</u>
<u>Where</u>
- 3 - is constant, the initial number of flights
- 6 - coefficient, number of flights per year
- y- number of years
- f- total number of flights
.Answer:
Step-by-step explanation:
Percent of change will always be positive because the change is an absolute value. As we know, absolute value is always a positive value because you don't pay attention to the direction, only the distance is important.
