Hello There!
Number 2
3.50x=40
Then, divide both of the numbers by 3.50.
You end up with X=11.42 is greater or equal to 12 movies
Number 3
5h+3
5 ‘5’ + 3 = 30
Number 4,5,6 are attached in images below.
Step-by-step explanation:
<h2>4.5 approximately is the answer.</h2>
Hum, this problem was difficult. You use the next expression to solve this problem. \[\cos (A - B) = \cos A \cos B + \sin A \sin B \] \[\cos (A + B) = \cos A \cos B - \sin A \sin B\] \[\cos (A - B ) - \cos (A +B ) =2 \sin A \sin B\] So \[\sin A \sin B = 0.5 \left( \cos(A - B) - \cos(A + B) \right)\] A = 1.8 x, B = 0.5 x \[\sin (1.8x) \sin (0.5x) = 0.5\left( \cos(1.8-0.5)x - \cos(1.8+0.5)x \right)\]\[= 0.5 \left( \cos(1.3x) - \cos (2.3x) \right)\] It's finish !!
Answer:
13.86
Step-by-step explanation: First- (2.3 * 4/10)
which gives you 27/10
Then (4.16 * 7/1)
Which gives you 11.16/1 (basically 11.16)
Then divide 27/10 which gives you 2.7
add 11.16+2.7
which adds up to 13.86
