Answer:
74.6 m
Step-by-step explanation:
First look at the rectangle, which is 15 meters wide horizontally and 18 meters long vertically. This rectangle contributes 2(18 m) + 15 m to the perimeter (the 15 m side is the bottom of the figure). That comes to 2(18) m + 15 m, or 51 m.
Next, look at the semicircle. Its diameter is 15 m and thus its total circumference is approximately (3.14)(15 m), or 47.1 m. We take only half of this circumference in calculating the perimeter of this figure: 23.6 m.
The total perimeter of this figure is 23.6 m + 51 m, or approximately 74.6 m.

Answer:
For the 1st question (4) For the 2nd question (1)
Step-by-step explanation:
(4) because 15000x+10000y needs to be less than or equal to 20000 or else they're going over the budget but x+y needs to be less than or equal to 15 as they can't make more than that.
(1) Divide both sides by pi and h then square root both sides.
The amount of passwords that Jina can make is only 12. Since the question says we are not allowed to use same letter twice that impacts the amount of passwords. In order to find the amount of passwords there is, we use the highest amount of letter choices, which is 4. Then the next letter can only have 3 letters. We can find out how many total passwords by doing 4*3 to get 12 different passwords.
