Answer:
x = 38°
Step-by-step explanation:
in the given question,
the two angles are complementary, because sum of their measures = 90°
so,
=》52° + x = 90°
=》x = 90° - 52°
=》x = 38°
A contractor purchased 7 dozen pairs of work gloves for 103.32 dollars.
He incorrectly calculated the unit price at 14.76 per pair for his expense report.
Let’s correct his work.
Solutions.
=> 7 pairs for gloves for 103.32 dollars.
Let’s find the cost of each pair of gloves.
=> 103.32 / 7 = 14.76 dollars.
according to our solution, he has a correct answer. The only problem in his work is the Unit rate representation.
=> 14.76 dollars/pair
(a)
In the function P(n) = 0.4n +5.7, P(n) is price of n grams of vitamins. So for the function x = P(n); x is price of n grams of vitamins.
The inverse of function determine amount of the vitamins for the known price of x dollars. So answer is,
The amount of vitamins (in grams) for a price of x dollars.
(b)
Let P(n) = x, So
Replace n by x and x by n in the given equation.
Simplify the equation for x.
So inverse of function is after interchange of variables,
(c)
Substitute 8.3 for x in the inverse equation to obtain the valur of P^-1(8.3).
So answer is 6.5.
