Answer:
Height of skyscraper's model = 5 feet
Step-by-step explanation:
Given:
Height of skyscraper = 1,450 feet
Scale model ratio = 1:290
Find:
Height of skyscraper's model.
Computation:
Height of skyscraper's model = Height of skyscraper × Scale model ratio
Height of skyscraper's model = 1,450 × (1/290)
Height of skyscraper's model = 5 feet
Okay lets go down the list. It's not right since 20²+99²=10201 √10201=101 and you said a is wrong it's have to be B. obtuse
Complementary pairs = APW and ZPW
Example: we multiply or divide both the top and the bottom of a fraction by the same number, it's just the same as multiplying or dividing by 1
Hope this helps! :)
