Sandy bought a soft drink for 4 dollars and 9 candy bars. She spent

1 answer:

5 0

9c + 4 = 49

The numbers by themselves represent the amount of dollars spent (4 and 49), but since you don’t know the amount of money each candy bar cost, you would put the amount of candy bars and a variable next to it to then solve ($5 per bar)

A lighthouse keeper has a 10 degrees angle of depression between the horizontal light beam and the line of sight from the ship.

Andrei [34K]

107.75m
This is a trigonometric ratio problem. the angle of depression (10) is opposite the height (19m) and the distance is adjacent to the distance (x). opposite ad adjacent sides to the angle is a tangent problem.
$tan \theta = \frac{opp}{adj}$
plus in values, we know.
$tan (10) = \frac{19}{x}$
switch tan(10) and x using the products property.
$x = \frac{19}{tan (10)}$
plug in to calulator to get answer
x=107.75

4/5w-12=2/3w what is the step by step answer to those equation?

Mariulka [41]

Kulay, there is no such thing as a "step by step answer" here. You seem to want a "step by step solution."

I must assume that by 4/5 you actually meant (4/5) and that by 2/3 you meant (2/3). Then your equation becomes:

(4/5)w - 12 = (2/3)w.

The LCD here is 5*3, or 15, so mult. every term by 15:

12w - 180 = 10w.
Add 180 to both sides, obtaining 12 w - 180 + 180 = 10w + 180.

Then 12w = 10w + 180. Simplifying, 2w = 180. What is w?
