Since they are complementary
x + y = 90
Sin(o) = Cos (90-0)
Therefore, Cos x = Sin y = 4/5 [ Because x and y are complementary]
Answer:
negative
Step-by-step explanation:
Answer:
(4x² + 3)(16
- 12x² + 9)
Step-by-step explanation:
A sum of cubes factors as
a³ + b³ = (a + b)(a² - ab + b²)
64
= (4x²)³ ⇒ a = 4x²
27 = 3³ ⇒ b = 3
Hence
64
+ 27
(4x² + 3)((4x²)² - (4x² × 3) + 3²)
= (4x² + 3)(16
- 12x² + 9)
27 is 54% of 50! You can set up fractions (proportions) as 27/50 = blank/100!
Well how do you get to 50 to 100? You multiply by 2! And whatever you do to the bottom you must do to the top! So 27 times 2 is 54!
Answer:
a. fly = 5.7
b. fly = 7.5
Step-by-step explanation:
a.
hoist/fly = 1 / 1.9
The new hoist is 3. To get this you have to multiply 1 by 3. That means you have to multiply 1.9 by 3 too.
1.9 * 3 = 5.7
b.
hoist/fly = 3/5 (this is the new ratio)
4.5 / 3 = 1.5
5 * 1.5 = 7.5
