The cost or unit price for purchasing each pair of work gloves is $1.19.
The cost of 7 dozen pairs of padded work gloves purchased by the contractor is $99.96.
The incorrect unit price calculated by the contractor is $14.28 per pair.
Now, we know 1 dozen is equal to 12 units.
Therefore,
The number of pairs of gloves purchased = 7 × 12 = 84
As the total cost is $99.96, the cost of each pair will be:
= $99.96 ÷ 84
= $1.19
The error by the contractor was that she didn't consider the word dozen in his calculation. She simply divided the total cost by 7 to calculate the price per pair.
The unit price of purchasing each pair of work gloves is $1.19.

Answer:
159.35 meters
Step-by-step explanation:
-We use the law of Sines to calculate the distance to the plateau's base.
-The angle of depression (90-20=70°) corresponds to this distance:
Hence, the distance to the base is 159.35 meters
Number 10 is D, Number 11 is D and Number 12 is C
V=4/3*pi*r^3
dV/dr=4/3*pi*d(r^3)/dr =4/3*pi*(3*r^2)=4*pi*r^2
On the equation log 1/9/k, this can be simplified by applying the quotient property of logarithms which says that the log a/b is equivalent to the difference of log a and log b. In the case of the given equation, log 1/9/k is equal to log 1/9 - log k. (Option A)
