-7/10 divided by 2/5 is -35/20 or -7/4 in the simplest form
-1/4 times (-4/3) is 4/12 or 1/3 in the simplest form
-3 1/3 or -10/3 times by -2 7/10 or -27/10 is 270/30 or 9
-10 2/7 or -72/7 divided by -4 4/11 or -48/11 is 792/336 or 33/14 in the simplest from
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 )
2852.1 rounded to the nearest tenth of a mile is still 2852.1
Look for points with whole number coefficients. (2,4) is such a point; (0,1) is another. To find points on the graph of the inverse of this function, all we have to do in this case is to reverse the order of the coefficients, so
(2,4) becomes (4,2) and (0,1) becomes (1,0). Only (4,2) is included in the list of answer choices, above, so the correct answer is (4,2).
