lesya692 [45]

Answer: 1163.2 feet

<u>Step-by-step explanation:</u>

Set up the proportion then cross multiply:

$\frac{height(girl)}{height(building)} = \frac{shadow (girl)}{shadow(building)}$

$\frac{4}{1454} = \frac{shadow (3.2)}{x}$

4(x) = 1454(3.2)

x = $\frac{1454(3.2)}{4}$

x = 1163.2

Let S be the universal set, where: S={1,2,3,...,18,19,20}

just olya [345]

Answer:

A∪B = {1,2,3,4,5,6,7,8,9,11,13,14,15,16,18,20}

A∩B = {1,5,6,7,8,9,11,14,15}

Step-by-step explanation:

A∪B is the elements in A or B. So, for this question, we just need to find the numbers that are in A or B. Remember not to add anything that is not in set A or B and not write the same number twice.

A∩B is the elements in A and B. Therefore, for this question, we just need to find the numbers which appeared in both set A and B.

Hope this helps :)
