(5x9)-(4x6) if you add parenthese
P=42 m
1/2 of P=21
1/2 of P= l+w
21=13+8
A=13×8
A=104 m^2. As a result, the length is 13 m, and the width is 8 m. Hope it help!
Step-by-step explanation:
We have 3(x + 3) = 10 + 2(x - y).
=> 3x + 9 = 10 + 2x - y
=> x = 1 - y
=> y = 1 - x.
(Rewritting it as a mathematical statement is the 1st line)
Answer:
Step-by-step explanation:
πr² = 18
v = 90 cm³
1/3πr² h = 90
1/3*18*h = 90
h = 90*3/18
h = 5*3 =15 cm
Answer:
C. 6.19 mi
Step-by-step explanation:
The angle between the two ship locations as viewed from the lighthouse is ...
23° -14° = 9°
This is opposite the known side of the triangle: 4 miles. The unknown side, the distance to the lighthouse from the second position, is opposite the 14° angle in the triangle. The Law of Sines can be used to find the distance (d) of interest:
d/sin(14°) = (4 mi)/sin(9°)
d = (4 mi)(sin(14°)/sin(9°)) ≈ 6.1859 mi
The ship is 6.19 miles from the lighthouse at the second sighting.
