Answer:
AB ≈ 15.7 cm, BC ≈ 18.7 cm
Step-by-step explanation:
(1)
Using the Cosine rule in Δ ABD
AB² = 12.4² + 16.5² - (2 × 12.4 × 16.5 × cos64° )
= 153.76 + 272.25 - (409.2 cos64° )
= 426.01 - 179.38
= 246.63 ( take the square root of both sides )
AB = ≈ 15.7 cm ( to 1 dec. place )
(2)
Calculate ∠ BCD in Δ BCD
∠ BCD = 180° - (53 + 95)° ← angle sum in triangle
∠ BCD = 180° - 148° = 32°
Using the Sine rule in Δ BCD
= = ( cross- multiply )
BC × sin32° = 12.4 × sin53° ( divide both sides by sin32° )
BC = ≈ 18.7 cm ( to 1 dec. place )
Answer:
B- $38.00
Step-by-step explanation:
Since there are two adults, you would multiply the cost of adults by number of adults. in this case that would be $10.75 x 2= $21.50. do the same for the kids and you will get $5.50 x 3 = $16.50. add 16.50 and 21.50 and you will get $38.00 which is your answer
hope this helped :D
Answer:
x=4/5

Answer:
246×17=4182
246<u>0</u>×17<u>0</u><u>0</u>=4182<u>0</u><u>0</u><u>0</u>
<u>(</u><u>one</u><u> </u><u>zero</u><u> </u><u>on</u><u> </u><u>the</u><u> </u><u>end</u><u>+</u><u>2</u><u> </u><u>zeroes</u><u> </u><u>in</u><u> </u><u>the</u><u> </u><u>end</u><u>=</u><u>3</u><u> </u><u>zeroes</u><u> </u><u>in</u><u> </u><u>the</u><u> </u><u>end</u><u> </u><u>on</u><u> </u><u>the</u><u> </u><u>answer</u><u>)</u>
16×3=48

<u>(</u><u>2 numbers after comma+1 number after comma=3 numbers after comma in the answer)</u>
To get the answer, you have to multiply 1,817.43 by 0.0344 (decimal form of 3.44%). So that would equal 62.52.
B. $62.52
