<u>The dependent and independent quality in the given situation:</u>

The given situation is that a long-distance telephone call cost increases with the number of minutes of the call. The two variables are dependent and independent.

The independent variable here in the given situation is the number of minutes of the call since it can be changed as much as we want

The dependent variable is the cost of the long-distance call as it relies on the number of minutes of the call. The cost increases when the number of minutes increases.

Using the Pythagorean theorem , the Square of the distance between the top of the piece and the Shadow Is the sum of the height of the piece. and the lenght of the shadow. basically Just build a triangle with the 3 points you are given: height of the piece, lenght of the shadow and distance between the 2. so it's sqrt(13^2+15^2) = sqrt(394) =19.8 cm

Jackson had $25 to spend on groceries . After purchasing 5 cantaloupes he had $2.50 left how much did each cantaloupe cost
charle [14.2K]
Since the price of the cantaloupes is unknown, it will have to represented by a variable. Let's use x.
If Jackson starts with $25 and buys 5 cantaloupes of an unknown price, this subtracts 5 times the amount of 1 cantaloupe (which is x) from that $25.
This is shown as 25 - 5x.
After spending that money, he has $2.50 left over.
This means 25 - 5x = 2.50.
Now you just need to solve this by first isolating the variable.
First, subtract 25 from both sides.
25 - 5x - 25 = -5x
2.50 - 25 = -22.5
Then, divide both sides by -5. It's -5 since 5 is the coefficient and it's negative, so -5.
-5x / -5 = x
-22.5 / -5 = 4.5
This means x = 4.5.
And if x is 4.5, then that means the cost of 1 cantaloupe is $4.50.

HOW WILL YOU DEAL WITH YOUR NEGATIVE ATTITUDES? ???​
fiasKO [112]

Answer:

I usually try and practice changing my mindset. Just try to look at things from another perspective, and if you can't, try thinking the OPPOSITE of what you thought.

Think homework is hard? Say to yourself, "Homework is easy." and trudge on through. After some time, your mindset *will* improve, and your attitudes will change from negative to positive.

Also, try to go out more often. Doing exercise, socializing, all of which will produce serotonin and will improve your outlook on life and attitude.
