Store 1 : 12 paper towels for 3.60
3.60 / 12 = 0.30......30 cents per roll
store 2 : 10 paper towels for 3.50
3.50/10 = 0.35....35 cents per roll
the better deal is store 1 with paper towels costing 30 cents per roll
The above statement is true meaning cos(π/₂-x)=sin(x)
Step-by-step explanation:
We know that sine and cosine function are mutual cofunctions.
Hence this would mean that these two functions are complimentary of each other meaning cos(π/₂-x) = sin(x)
This can be verified mathematically by assuming “x” as 30°
Hence Cos (π/₂-30°) = cos 60°= 0.5 (from trigonometric table values)
Similarly Sin 30°= 0.5 (from trigonometric table values)
This can be proved through using the formula
Cos(A-B)= Cos A.Cos B + Sin A.Sin B
Here A=90° and b=x°
Putting the values we get (it is to be remembered that cos 90°=0 and sin 90°=1)
Cos 90°.cos x+ sin 90.sin x
0+sinx= sinx
Hence it is proved that cos(π/₂-x)=sin(x)
Answer:
C) The diagram in this figure illustrates a reflex angle
Step-by-step explanation:
Given : A diagram with an angle.
To find : The diagram in this figure illustrates a _______ angle.
Solution : We can see from figure it is greater than 180 degree and less than 360 degree.
By the definition of reflex angle : The reflex angle is the larger angle. It is more than 180° but less than 360°.
Therefore, C) The diagram in this figure illustrates a reflex angle.
Answer:
W<6
Step-by-step explanation:
3 times W
So 3W is less than < 18
Do 18 / 3 =6
Answer:
300ft^3
Step-by-step explanation:
I'm guessing what the question meant be triangular is a triangular prism.
The volume formula for a triangular prism is 1/2(lwh)
L=10
W=10
H=6
(6)(10)(10)=600
600/2=300
V=300ft^3
Hope this helps! :)
