Answer:
$23.98
Step-by-step explanation:
22.50 + 6.6% (1.485) = $23.98
Answer:
For the parallelogram to be a rectangle, at least one angle must be a right angle or a 90° angle, we know that:
13x + 34° + 10x + 10° = 90°
=> 13x + 10x = 90° - 34° - 10°
=> 23x = 46°
=> x = 46°/23 = 2°
$12 x .30= $3.60 mark up so new price was $15.60.
$15.60 x .25= $3.90 discount, so the new price with discount would be $11.70
Answer:
(8,5)
Step-by-step explanation:
5x-2y=30
lets substitute "8" as x and see where that takes us
5(8)-2y=30
40-2y=30
subtract 40 on both sides
-2y=-10
divide by "-2" on both sides
y=5
(8,5) is your answer
Answer:
distance TS ≈ 19 m (nearest meter)
Step-by-step explanation:
The point T is on the horizontal ground and the angle of elevation of the top R of a tower is 63° and the height of the tower is 38 m high. The illustration forms a right angle triangle. The height RS of the tower is the opposite side of the triangle formed. The hypotenuse side of the triangle is the point from the ground T to the top of the tower R. The adjacent side of the triangle is the side TS.
using tangential ratio
tan 63° = opposite/adjacent
tan 63° = 38/adjacent
cross multiply
adjacent tan 63° = 38
divide both sides by tan 63°
adjacent side = 38/tan 63°
adjacent side = 38/1.96261050551
adjacent side = 19.3619670807
distance TS ≈ 19 m (nearest meter)
