Answer:
7 cajas grandes y 3 cajas pequeñas
Step-by-step explanatio:
If a function wouldn't represent area of a circle its domain would be all real numbers. For any number r we can calculate f(r)
But since radius of circle cannot be negative and it also doesnt make sense that it is 0 the answer would be all positive real numbers
Answer is a.
18.56 feet
Catie creates a similar triangle with the ladder so we can create a proportion to solve for the height.
Convert all values to feet . 16in = 1.33 ft . 5ft 6 in = 5.5 ft
Insert values into proportions
Cross multiply to get
24.75=1.33x
divide both sides by 1.33
x=18.56ft
8 1/6 + 7 3/8
1/6 = 4/24 3/8 = 9/24
4/24 + 9/24 = 13/24
8+7 = 15
Answer = 15 13/24
