I don't think they are. It sounds like a direct proportion to me. The more rice you buy, the higher the cost.
Cost = k * quantity.
That would be the most general formula.

Jonathan has no money and he owes three friends fifteen dollars each. What is his worth?
Answer:
-$45
Step-by-step explanation:
Find how much he owes his friends in total by multiplying 3 by 15:
3(15)
= 45
So, he owes his friends $45.
Since he has no money, we can find his worth by subtracting 45 from 0:
0 - 45
= -45
His worth is -$45.

Answer:
A&C
Step-by-step explanation:
They are negative and even and they are not positive and even too.
Answer:
A
Step-by-step explanation:
Technically A and C are correct but we are dealing with only negative even values. A non-positive integer is any negative number or zero but we don't have that value so it makes more sense to choose A than C. B is incorrect because a whole number can't include a negative number, a fraction, or a decimal. D is also incorrect because a non-negative integer is a positive number which we don't have in the set.

When Ms. Perez has excellent service at a restaurant, the amount she leaves for a tip t is at least 20% of the cost of the meal c. Write a model representing the amount of the tip.
Answer:
t ≥ 0.2c
Step-by-step explanation:
Her tip is at least 20% of the cost of the meal, so her tip is greater than or equal to 20% of the cost of the meal
tip ≥ 20% of the cost of the meal
t ≥ 20% of c
Another way of writing "20% of c" is multiplying the two values, so we have
20% of c = 20% * c
t ≥ 20% * c
To convert from a percentage to a decimal, we can divide the percentage by 100. Here, we have
20% = 0.2
t ≥ 0.2 * c

At the beginning of March, a store bought a leather couch at a cost of $960.70 and marked it up 20%. At the end of the month, the leather couch had not sold, so the store marked it down 25%. What was the discounted price? Submit
Answer: $864.63
Step-by-step explanation:
First find the original price. Write 20% as the decimal 0.20 before using it in the equation.
price
= cost+mark-up
= 960.70+0.20×960.70
= 960.70+192.14
= 1,152.84
The original price was $1,152.84.
Now find the discount price. Write 25% as the decimal 0.25 before using it in the equation.
discount price
= original price–discount
= 1,152.84–0.25×1,152.84
= 1,152.84–288.21
= 864.63
The discount price was $864.63.

Answer:
45 degrees
Step-by-step explanation:
Hi there!
We're given that one of the triangle's exterior angles is 90 degrees. Using that, we can solve for the corresponding interior angle by subtracting 90 from 180 degrees:
180-90 = 90
Given that the two legs of this right triangle are of equal length, we know that the remaining two angles both measure x. Knowing that the sum of the interior angles in a triangle is 180 degrees, we can set up an equation:
x+x+90=180
2x=90
x=45
Therefore, x is 45 degrees.
In fact, any right triangle with legs of equal length will be a 45-45-90 triangle, meaning the other two angles measure 45 degrees.
I hope this helps!

Step-by-step explanation:
lines that are parallel have the same gradient. So the gradient is 4/5
Lines that are perpendicular have "opposite reciprocal" gradient: flip the sign, then flip the numerator and denominator (top/bottom). So the gradient is -3/4

what is the domain of y=cos 0
Answer:
The domain of y = cos θ is all real numbers. This is because any real number can be plugged in for θ and y will be equal to a real number. This can be shown graphically because the y = cos θ will go on infinitely both to the right and left.
0.5t + 0.25(t +16) =4 + 0.75t
Answer:
0.5t + 0.25(t +16) =4 + 0.75t
0.5t + 0.25t + 4 = 4 + 0.75t
0.5t+ 0.25t – 0.75 t = 4– 4
0.5t +0.25t–0.75t = 0 —> 0 = 0
I hope I helped you^_^
Answer: All Real Numbers or A.R.N
Step-by-step explanation:
Given
0.5t + 0.25 (t + 16) = 4 + 0.75t
Expand parentheses and apply the distributive property
0.5t + 0.25 · t + 0.25 · 16 = 4 + 0.75t
0.5t + 0.25t +4 = 4 + 0.75t
Combine like terms
0.75t + 4 = 4 + 0.75t
Subtract 0.75t on both sides
0.75t + 4 - 0.75t = 4 + 0.75t - 0.75t
4 = 4
Since both sides are left with the same term, this means any number would be able to make the equation true.
Therefore the answer would be All Real Numbers, or [tex]\boxed{A.R.N}[/tex]
Hope this helps!! :)

A)Negative infinity less-than x less-than infinity
B)0 less-than x less-than infinity
C)0 less-than-or-equal-to x less-than infinity
D)1 less-than-or-equal-to x less-than infinity
Answer:
C is the answer
Step-by-step explanation:
The domain can't be minus. That's the only stipulation. It can be equal to 0 or anything larger than 0. It just can't go into the minus numbers.
0≤x<infinity.

A steel ball has a volume of 1500 cm.
The density of the ball is 95 g/cm'.
Find the mass of the ball in kg.
Answer:
95kg
Step-by-step explanation:
Mass÷Volume=Density
Therefore, Mass = Volume × Density
Mass = 1500 × 95
Mass = 95,000g
Since we were asked to find the mass in kg:
1000g = 1kg
Therefore, 95,000g = 95kg
If angle 1 and angle 2 are vertical angles, and the m<1 = 10x - 9 and m<2 = 4x + 15. Find the value for x.
Answer:
x = 4
Step-by-step explanation:
Vertical angles are equal.
m∠1 = m∠2
10x - 9 = 4x + 15
Add 9 to both sides
10x = 4x + 15 + 9
10x = 4x + 24
Subtract 4x from both sides
10x -4x = 24
6x = 24
Divide both sides by 6
x = 24/6
x = 4

Step-by-step explanation:
The ratio if the number if books to the cost in dollars is 1 : 4
To plot on a coordinate grid, we first look at the horizontal direction (x-axis)
Take the number of books to be values of the x-coordinate.
Start at the origin and travel the necessary distance to the left or the right then move up or down in the vertical direction to mark the y-coordinate.
The corresponding cost to be the values of the y-coordinate. Mark or plot at the intersection of the two numbers.
Solve for x.
21)
60°
8x
80°
Answer:
x = 5
Step-by-step explanation:
Sum of angles = 180, so
60 + 80 + 8x = 180
140 + 8x = 180
8x = 180 - 140 = 40
x = 40/8 = 5
Solve the simultaneous equations. to. 3 significant figures.
3x^2 + y^2 = 20
2x + y =3
Answer:
check explanation
Step-by-step explanation:
in eqn 2,
y = 3 - 2x
substitute for it in eqn 1
3x² + y² = 20
3x² + (3 - 2x)² = 20
3x² + 9 - 12x + 4x² = 20
Group like terms;
3x² + 4x² - 12x = 20 -9
7x² - 12x = 11
x(7x - 12) = 11
x = 11,
OR
7x - 12 = 11
7x = 11 + 12
7x = 23
x = 23/7
x = 3.286
To get y, substitute for x in eqn 2
WHEN x = 11,
y = 3 - 2(11)
y = 3 - 22
y = -19
WHEN x = 3.286
y = 3 - 2(3.386)
y = -3.772
is the mistake one two three or is their no mistake
Answer:
the mistake is that to "remove" the 1/2 on the left you would have to multiply by 2 (or divide by 1/2 but no one does that)
the result would be that 2h-4 = 10 should actually be 2h-4 = 20
