At a given time of day, the ratio of the height of an object to the length of its shadow is the same for all objects. if a 3-ft stick in the ground casts a shadow of 1.2 ft, find the height of a tree that casts a shadow that is 14.56 ft.

  36.4 ft

Step-by-step explanation:

(object height)/(shadow length) = (3 ft)/(1.2 ft) = (tree height)/(14.56 ft)

Multiply by 14.56 ft:

  tree height = (14.56 ft)(3/1.2) = 36.4 ft

The height of the tree is 36.4 feet.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
