Answer:
394 m
Step-by-step explanation:
From the solution diagram attached ;
The distance between boat and base of hill is represented as d ;
Using the trigonometric relation :
Tan θ = opposite / Adjacent
Tan 13 = 91 / d
Tan 13 * d = 91
d = 91 / Tan(13)
d = 394.16 m
d = 394 m (nearest meter)
Answer:
Step-by-step explanation:
9. Correct, D
-3Y + 9X <= 12
3Y - 9X => -12
3Y => -12 + 9X
Y => -4 + 3X
10. D
11. D
12. Correct, B
13. Correct, E
14. A
15. B
Answer:
Step-by-step explanation:
Semicircle:
diameter = length of the rectangle = 25 cm
Half circumference = πd/2
= 3.14 * 25/2 = 39.25 cm
Perimeter of the figure = 39.25 + 20 + 25 + 20
= 104.25 cm
Answer:
-6,-4
Step-by-step explanation:
The coordinates of the point is -2,2 so you subtract 4 and 6. That is -6.-4
