Since there are 36 inches in a yard, multiply 16 by 18 and divide that answer by 36
18*16=288
288/36=8

Answer:
k = 42
Step-by-step explanation:
given that x and y vary inversely then the equation connecting them is
y =
← k is the constant of variation
To find k use the condition y = 6 when x = 7
k = yx = 6 × 7 = 42
I found the answer key t your worksheet. If you need an explanatin ask in comments and I will get back ASAP.
By using trigonometric relations, we will find that:
sin(θ) = (√33)/7 = √(33/49)
<h3>How to find the value of the sine?</h3>
Remember that for a right triangle, we have the relations:
cos(a) = (adjacent cathetus)/(hypotenuse)
sin(a) = (opposite cathetus)/(hypotenuse).
Here we know that:
cos(θ) = 4/7
Then we can say that we have a triangle with an adjacent cathetus of 4 units and a hypotenuse of 7 units. Now we need to find the other cathetus.
opposite cathetus = √(7^2 - 4^2) = √33
Then we can write:
sin(θ) = (√33)/7 = √(33/49)
