Answer:
16/20
Step-by-step explanation:
Since this is a right triangle
sin theta = opp side / hypotenuse
sin theta = 16/20
4w-7k=28
Move variable to the right to get -7k=28-4w
Divide both sides by -7
k= -4+4/7w
Let's make the mysterious, original price not-so-mysterious by calling it <em>x. </em>245.97 is 3/5 of x.
We can equation this.
245.97 = 3/5x
x = 245.97 / (3/5)
x = 409.95
The answer, I believe, is $409.95. Hope this helps!
The phrase - product of 11 and x is correct because the word product is the final result of multiplying.
The point represents a multiplication symbol as it would be confusing to some to write 11 x X
Answer: 5.8 cm
Step-by-step explanation:
Given that the chord is 0.8 cm from the center of a circular ring and the radius r = 3 cm
Using pythagorean theorem to find part of the cord
3^2 - 0.8^2
= 9 - 0.64
= 8.36
Square root of the value above gives 2.89
The length of the chord = 2 × 2.89 = 5.782
= 5.8 cm (to the nearest tenth)
