Step-by-step explanation:
It will take 2 hours
(1/8)*8=1
(1/4)*8=8/4
8/4=2
Answer:
Example: 5(3x + 8)
= 5(3x) + 5(8)
= 15x + 40
Step-by-step explanation:
Answer: At least 32 calendars.
Step-by-step explanation:
Since they already have $350 out of the $600, they only need to raise $250 more (600-350).
Each calendar is $8
To find how many calendars are needed to raise $250, divide it by $8 (250/8=31.25)
Since you cannot sell .25 of a calendar it would round up to be 32.
You can first use the fundamental trigonometric identity:
sin(x) ^2 + cos(x) ^2 = 1
=> cos(x) ^2 = 1 - sin(x) ^2
=> cos(x) ^2 = 1 - (-4/5)^2 = 1 - 16/25 = (25 - 16) / 25 = 9 /25
=> cos (x) = +/ - √ (9/25) = +/- 3/5
Now, analyze the sign.
In the fhird quadrant the cosine is negative, so the answer is cos(x) = - 3/5.
Answer: option C. - 3/5
