Answer: sqrt(650)
Step-by-step explanation:
sin 45 = 5sqrt(13)/y
y = 5sqrt(13)*2/sqrt(2) = 10sqrt(13)/sqrt(2) = sqrt(650)
214.7 is greater than 214.275

Answer:
Step-by-step explanation:
- Total number of plants = 15
- Total cost = $96
- Cost of pink flowering plant = $8
- Cost of purple flowering plant = $5
<u>Let x and y be the number of plants bought. Then we have equations:</u>
- 8x + 5y = 96
- x + y = 15 ⇒ y = 15 - x
<u>Substituting y in the first equation:</u>
- 8x + 5y = 96
- 8x + 5(15 - x) = 96
- 8x + 75 - 5x = 96
- 3x = 96 - 75
- 3x = 21
- x = 7
Correct option is the second one
