3. A trail mix recipe asks for 4 cups of raisins for every 6 cups of peanuts. There is

a. Write the equation for the relationship that has constant of proportionality
greater than 1. Graph the relationship.
b. Write the equation for the relationship that has constant of proportionality less than 1. Graph the relationship.
Answers
Answer:
r = 2/3p
A trail mix recipe asks for 4 cups of raisins for every 6 cups of peanuts.
There is proportional relationship between the amount of raisins, r (cups), and the amount of peanuts, p (cups), in this recipe.
The ratio of raisins and peanuts = 4:6 or 2:3
It would be same for every mixture.
If r cups of raisins and p cups of peanuts then their mixture ratio is r:p
Step-by-step explanation:
pls heart and give brainliest
The equation where the constant of proportionality is greater than 1 is [tex]\mathbf{p = 1.5r}[/tex], and the equation where the constant of proportionality is less than 1 is [tex]\mathbf{r = 0.67p}[/tex]
(a) Constant of proportionality greater than 1
Represent peanuts with p, and raisins with r.
So, the ratio is given as:
[tex]\mathbf{p : r = 6 : 4}[/tex]
Express as fraction
[tex]\mathbf{\frac pr = \frac 64}[/tex]
Multiply both sides by r
[tex]\mathbf{p = \frac 64r}[/tex]
[tex]\mathbf{p = 1.5r}[/tex]
(b) Constant of proportionality less than 1
In (a), we have:
[tex]\mathbf{p = 1.5r}[/tex]
Divide both sides by 1.5
[tex]\mathbf{r = \frac{1}{1.5}p}[/tex]
[tex]\mathbf{r = 0.67p}[/tex]
The graphs of [tex]\mathbf{p = 1.5r}[/tex] and [tex]\mathbf{r = 0.67p}[/tex] are the same.

6 x 4 = 24
Step 4: Multiply the result by 5:
24 x 5 = 120
Step 5: Multiply the result by 6:
120 x 6 = 720
Step 6: Multiply the result by 7:
720 x 7 = 5040
Step 7: Multiply the result by 8:
5040 x 8 = 40,320
Step 8: Multiply the result by 9:
40,320 x 9 = 362,880

What is the missing number in this pattern?
10,
11,
21,
32,
53,
85,
138,
223,
Answers
One criterion that we can use to analyze patterns is to look at the difference between consecutive terms. With this, we will see that the missing number is 361.
For the first two we have:
11 - 10 = 1
for the second and third:
21 - 11 = 10
for the fourth and third:
32 - 21 = 11
for the fifth and fourth:
53 - 32 = 21
We already can see the pattern, the n-th term can be written as:
Aₙ = Aₙ₋₁ + Aₙ₋₂
This means that the missing number, the next one, will just be equal to the sum of the two previous ones.
Then the next number is:
N = 138 + 223 = 361

Select all the quadrilaterals that have diagonals which cross at right angles. Please help..
Answers
Answer: C and D
Step-by-step explanation:
We need to find all the figures that are rhombuses. These figures are C and D.
The quadrilaterals C and D are those for which the diagonals cross at right angles.
What is a Quadrilateral?Quadrilateral are closed geometrical shapes having four sides, four angles and four vertices. Some of the common quadrilaterals include rectangles, square, parallelogram and the rhombus.
Interior angles of any type of quadrilateral always sums up to 360°.
Diagonals of a quadrilateral is the straight line formed by joining opposite vertices.
For every quadrilateral, there are two diagonals.
Figure A is a rectangle. The diagonals of a rectangle bisects each other, but is not perpendicular bisector. This means that diagonals of figure A does not cross at right angles.
Figure B is a parallelogram. Properties of diagonals are almost same in rectangles and quadrilateral. Diagonals bisect each other, but is not perpendicular. So diagonals of figure B also does not cross at right angles.
Figure C is rhombus. Diagonals of a rhombus perpendicularly bisect each other. Therefore diagonals of figure C cross at right angles.
Figure D is square. Again the diagonals of a square perpendicularly bisect each other. Therefore diagonals of figure D cross at right angles.
Hence diagonals of figures C and D cross at right angles.

Step-by-step explanation:
Any regular polygon has exterior angles = to 360 / number of sides.
so a 9-gon has 9 sides. The exterior angle = 360 / 9 = 40
Each exterior angle will be 40 degrees.
Try it with simpler n-gons. A triangle has 3 sides. The exterior angle is 360 / 3 = 120
A square has 4 sides. Each exterior angle is 360 / 4 = 90
