Answer:
B
Step-by-step explanation:
The requirement is 3 chlorine tablets per every 2,000 galloons of water.
The lifeguards added 8 chlorine tablets for 10,000 galloons of water.
To get from 3 tablets to 8 tablets, we multiply by 8/3.
By multiplying 2,000 galloons of water by 8/3, we acquire approximately 5,333 galloons of water.
Since 5,333 is less than 10,000, the Park Pool has less chlorine than the safety standards require.
For the given triangle, the tan of angle A equals C. 
.
Step-by-step explanation:
Step 1; In the given triangle, the opposite side has a length of 15 units, the adjacent side has a length of 36 units while the hypotenuse of the triangle measures 39 units. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.
cos A = 
.
Step 2; The opposite side's length = 15 units,
The adjacent side's length = 36 units.
cos A = 
, dividing the numerator and the denominator by 3, we get
cos A = , which is option C.
For each, divide the amount by the number of wings
7 divided by 8: 0.875 = $0.88 per wing
10 divided by 12: 0.8333 = $0.83 per wing
17 divided by 20: 0.85 = $0.85 per wing
Looking at each result, the middle one (the $10 for 12 wings) is the best deal
It is a rational number because it can be expressed by a quotation or fraction of an integer
The expression equivalent to <span> ^4 sqrt 144a^12 b^3 will be found by simplifying our expression as follows:
</span><span> ^4 sqrt 144a^12 b^3
=(144a^12b^3)^(1/4)
=(12^2a^12b^3)^(1/4)
=12^(1/4*2)a^(12*1/4)b^(3*1/4)
=12^(1/2)a^3b^(3/4)
Answer: </span>12^(1/2)a^3b^(3/4)
