A store sells candy at $.50, $1, $1.50, $2, and $3 per kilogram. you can see that the unit price of candies that $3 buy very inversely. What is the constant of variation?
Answer:
constant of variation = 3
Step-by-step explanation:
Given that a store is selling different candies costing $.50, $1, $1.50, $2, and $3 per kilogram.
As given
Amount available to buy candies = $ 3
Suppose
Unit price of candies = x
Number of candies bough = y
Constant of variation = k
As we know the unit price of candies and number of candies bought vary inversely. As the unit price would increase the the number of candies bought in available amount ($3) would decrease.
So our formula to calculate formula for constant of variation would be as shown below:
k= xy →(1
Case 1
if we take unit price x to be $0.5, then we can buy 6 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:
k = (0.5)(6) = 3
Case 2
if we take unit price x to be $1, then we can buy 3 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:
k = (1)(3) = 3
Case 3
if we take unit price x to be $1.5, then we can buy 2 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:
k = (1.5)(2) = 3
Case 4
if we take unit price x to be $2, then we can buy 1.5 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:
k = (2)(1.5) = 3
Case 4
if we take unit price x to be $3, then we can buy 1 kg of candies in $ 3. In this case constant of variation can be found from above equation (1) as follows:
k = (3)(1) = 3
So, our constant of variation is 3.

What is the fractional equivalent of repeating decimal 0.5
The fractional equivalent of the repeating decimal 0.5 is 5/9.
To convert the repeating decimal into a fraction, we can assign a variable, let's say x, to the repeating decimal. In this case, x = 0.5555...
Next, we multiply both sides of the equation by a power of 10 that will eliminate the repeating part.
10x = 5.5555...
Now,we subtract the original equation from the new equation to eliminate the repeating part:
10x - x = 5.5555... - 0.5555...
9x = 5
Simplifying the equation, we get:
x = 5/9
Therefore, the correct answer is A. 5/9.

A 18 -inch laptop has a screen that is 7 inches tall. How wide is the screen?
We are given:
Diagonal Length of the screen = 18 inches
Length of the screen = 7 inches
Width of the screen = x inches
Finding the width:
In the image, we notice a right-angle triangle
So, we can find x using the Pythagoras theorem
Using the Pythagoras theorem:
18² = 7² + x²
x² = 18² - 7²
x² = 324 - 49
x² = 275
x = 16.6
Hence, the screen is 16.6 inches wide
We are to find the width of the laptop
The width of the laptop is 16.6 inches
Diagonal length of the laptop = 18 inches
Length of the laptop = 7 inches
Width of the laptop = x inches
Using Pythagoras theorem
Diagonal ² = length ² + width ²
18² = 7² + x²
x² = 18² - 7²
x² = 324 - 49
x² = 275
find the square root of both sides
x = √275
x = 16.58
Approximately,
x = 16.6 inches

In one particular suburb, there are 28 families that own a pug. If these owners make up 80% of all dog owners in this suburb, then how many dog owners are there in this neighborhood?
Answer:
60%
Explanation:
To get percentages, take the part of a population that is being specified and divided that by the whole population and multiply that value by
100%
So there are 30 people that own boxers, this is the specific population that is being compared to the whole dog-owning population, which is comprised of 50 total families. So 30 50 can be reduced to 3 5 and that gives us 0.6
When that value is multiplied by
100%, it gives us our percentage of 0.6 ⋅ 100% = 60
