I got you hun!
27= 3x is the equation you will need
27 is the total the coach needs making it the total. Since each pack comes with 3 you will mutiply the amount of pack, or x, by 3.
X=9
we know this because if you divide 3 by 27 to get it on the other side we get 9. This means the coach needs to buy 9 packs of baseballs for the team.
27=3(9)
Hope this helps!
Answer:
sin(A-B) = 24/25
Step-by-step explanation:
The trig identity for the differnce of angles tells you ...
sin(A -B) = sin(A)cos(B) -sin(B)cos(A)
We are given that sin(A) = 4/5 in quadrant II, so cos(A) = -√(1-(4/5)^2) = -3/5.
And we are given that cos(B) = 3/5 in quadrant I, so sin(B) = 4/5.
Then ...
sin(A-B) = (4/5)(3/5) -(4/5)(-3/5) = 12/25 + 12/25 = 24/25
The desired sine is 24/25.
Answer:
$11.04
Step-by-step explanation:
To calculate the tip, you would find 20% of 55.22 by doing this:
55.2 x 0.20 = ?
You will then get 11.04, and that is the tip.
Hope that helps :>
Answer:
C. 12cm
Step-by-step explanation:
Sum of any two sides of a triangle must always be greater than the third side.
here 8 + 7 = 15 > 12
Hence, option C is the correct answer.
Answer:
The given equation is
Which is the definition of the angle of repose.
<em>Remember that the angle of repose refers to the angle between the horizontal plane and the inclined side of the cone formed when we allow to fall freely granular materials.</em>
We know by given
Replacing these values, we have
Therefore, the angle of repose is 38.29° approximately.
Now, if the base diameter is 104 feet, the height would be
Therefore, the height would be 65.8 feet, assuming that the angle of repose is the same.
