Answer:
tan20.tan35.tan45.tan55.tan70 =1
Step-by-step explanation:
tan20.tan35.tan45.tan55.tan70
=tan(90-70) . tan(90-55) . tan45 .tan55. tan70
[we know, tan(90-θ)=cotθ]
=cot70 . cot55 . tan45 .tan55. tan70
= { tan70°.cot70°} {tan55°.cot55°}.tan45°
=1 . 1 . 1 [we know, tan∅.cot∅ = 1 & tan45°=1]
=1
pls mark as brainliest.
Answer:
You first need to know what number 6 4/5 is, which is 6.8. To figure it out, you multiply 6 by 5 then add 4 and put the number you get on top of the fraction so it would be 34/5 = 6.8
6.9 is the answer
6.9 is bigger than 6.8 and smaller than 7
Answer:
It will take 1.25 seconds to reach the ground.
Step-by-step explanation:
The equation of the containers pathway can be modeled by the equation given below :
t is time in seconds
It is required to find the time taken by the container to reach the ground. When it reached ground, its height is equal to 0 such that,
So, it will take 1.25 seconds to reach the ground.
Answer: im not sure sorry
Step-by-step explanation:
1 dozen = 12
First you would multiply.
3.25 x 12 = 39 cupcakes total
1/3 x 12 = 4 cupcakes with vanilla icing
Then you subtract.
39 - 4 = 35 cupcakes with chocolate icing
Then to get the answer back in to terms of dozens, divide by 12.
35/12 = 2 11/12
Hope this helped
