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 2x+3y=1500 in slope intercept form?
Answer:
y=-2/3x+500
Step-by-step explanation:
Slope-intercept form: y=mx+b So, you need to get y by itself.
2x+3y=1500 Subtract 2x on both sides.
-2x -2x
3y=-2x+1500 Divide both sides by 3.
/3 /3
y=-2/3x+500
(The slope is -2/3 and the y-intercept is 500.)
Hope this helps!! Have a wonderful day ^^

Answer:
b = 9
Step-by-step explanation:
Hello, once again.
Perpendicular lines have negative reciprocal slopes.
The slope would be -2.
Plug the y and x values in.
y = -2x + b
5 = -2(-2) + b
5 = -4 + b
b = 9

Drag the tiles to the correct boxes to complete the pairs. Match the values based on parallelogram ABCD, shown in the figure. length of value of m∠DAB value of 56 arrowRight 4 arrowRight 44 arrowRight 2 arrowRight
Answer:
56 ---> m< DAB
4 ---> length of line BC
44 ---> value of y
2 ---> value of x
Step-by-step explanation: edmentum test answer
The length of BC is 4 units, the value of y is 44, a measure of the angle DAB is 56 degrees, and the value of x is 2.
What is parallelogram?In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
Parallelogram ABCD
From the figure:
6 - x = x + 2
2x = 4
x = 2
Length of BC = 6 - x = 6 - 2 = 4 units
12 + y = 100 - y
y = 44
Angle DAB = 100 - 44 = 56 degrees
The value of x = 2
Thus, the length of BC is 4 units, the value of y is 44, a measure of the angle DAB is 56 degrees, and the value of x is 2.

Tom read 240 pages of a book containing 360 pages. What fraction of the book did he read?
PLS simplify the answer!!
Answer:
2/3
Step-by-step explanation:
360 - 240 = 120
120 x 3 = 360
if 120 is 1/3 of 360, then 240 is 2/3 of 360

Answer:
P = 25m - 15
Step-by-step explanation:
Kindly find attached the table of values for your reference.
Step one:
given data
let us set up the coordinate using the value of p and m
p=35
p1=10
m=2
m1=1Tthe cordinate is (p1,p),(m1,m)= (y1,y),(x1,x)
(1,10), (2, 35)
the slop is given as, slope m = (p- p1)/(m - m1)
m=(35-10)/(2-1)
m = 25
from the equation of line y=mx+c
y = 25x + c
10 = 25(1) + bc
c= -15
y = 25x - 15
in term of m and p we have P = 25m - 15
I need this in standard form slope intercept and point slope form.
Answer:
m= 3/4
Step-by-step explanation:
Use the slope formula to find the slope m

You have 3 coins. One of them may be a fake that is either heavier or lighter than the real coins. Using a balance scale what is the best possible number of weighings that you need to always find the possible fake
Answer:
Two weighing
Step-by-step explanation:
In the context, it is given that one of the three coins is fake and the other two are real. It is also mentioned that the fake coin is either heavier or lighter than the other two real coins.
Now to find the fake coin, we take a balance scale and lace one coin on one pan of the balance and place the second coin on the other pan of the same balance. We keep the third coin aside.
Now we check the balance scale. If the scale is balance, then we can conclude that the coin that we kept aside is the fake coin as both the real coins have same weight.
Now we replace the one of the coin on the pan with the coin that is kept aside and check the balance. Remember now on the pan, there is one real coin and one fake coin. The balance scale will be dis-balance as the fake coin is either heavy or light than the real coin. Thus we can identify the fake coin.
In order to conduct an experiment, 4 subjects are randomly selected from a group of 20 subjects. How many different groups of four subjects are possible?
Answer:
The number of ways to form different groups of four subjects is 4845.
Step-by-step explanation:
In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.
The formula to compute the combinations of k items from n is given by the formula:
[tex]{n\choose k}=\frac{n!}{k!\times (n-k)!}[/tex]
In this case, 4 subjects are randomly selected from a group of 20 subjects.
Compute the number of ways to form different groups of four subjects as follows:
[tex]{n\choose k}=\frac{n!}{k!\times (n-k)!}[/tex]
[tex]{20\choose 4}=\frac{20!}{4!\times (20-4)!}[/tex]
[tex]=\frac{20\times 19\times 18\times 17\times 16!}{4!\times 16!}\\\\=\frac{20\times 19\times 18\times 17}{4\times3\times 2\times 1}\\\\=4845[/tex]
Thus, the number of ways to form different groups of four subjects is 4845.
