Answer:
12.2 *3 = 36.6 feet
Step-by-step explanation:
since yards is the input, you would multiply the input by 3 to get feet
so the equaton would look something like: f(x) = 3x where x is the input
so when x = 12.2 you would replace x with 12.2 to get:
have f(12.2) = 3(12.2)
Using relations in a right triangle, it is found that:
sin(x) = cos(y) = 0.6.
Since angles x and y are complementary, we have that sin(x) = cos(y), that is, the ratio is of 1.
<h3>What are the relations in a right triangle?</h3>
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
Applying the Pythagorean Theorem, the hypotenuse is given by:
h² = 3² + 4²
h² = 25
h = 25.
Hence, applying the definitions:
Since angles x and y are complementary, we have that sin(x) = cos(y), that is, the ratio is of 1.

Answer:
x=1 1/18
Step-by-step explanation:
7(x+8)+4=-11(x-8)-9
distribute- 7x+56+4=-11x-88-9
7x+60=-11x+79
subtract 60 from both sides (60),(79)
7x=-11x+19
add 11x on both sides
18x/18 and 19/18
which gives you x=1 1/18 or 19/18
Answer: The initial number of shoes in the store is 300.
Step-by-step explanation:
Given : Kelly is a salesperson at a shoe store, where she must sell a pre-set number of pairs of shoes each month.
At the end of each work day the number of pairs of shoes that she has left to sell that month is given by the equation
, where S = Number of pair of shoes Kelly still needs to sell.
x = Number of days she has worked that month.
When x= 0 , we get S= 300
i.e. When she started working in that month , she has 300 pairs of shoes to sell.
Therefore , Number 300 means that the initial number of shoes in the store is 300
