We need to know about linear and proportional relationship to solve this problem. Statement 2 is true, the description shows a linear relationship and a proportional relationship.
Linear relationship is a relationship between two variables where if one increases the other increases or if one decreases the other decreases. The varibales in a linear relationship form a straight line on graph. Proportional relationship is the relationship between two variables where the ratio between pairs of different data always remains constant. In the given question, a 12 ounce cup costs $1.97, a 16 ounce cup costs $2.62 and a 20 ounce cup costs $3.27. The price of each cup increases with increase in capacity of the cup, so we can say that the cup capacity and price have a linear relationship. The ratio between each pair can be given by
12/1.97=6.10
16/2.62=6.10
20/3.27=6.10
The ratios between every pair is same, so it is a proportional relationship.
Thus we found that the description shows a linear relationship and a proportional relationship between the cup capacity and it's price, statement 2 is the right option.

A canteen has fixed cost of 1500 per week.meal costs 5 each are sold at a fixed price of 9 each.write down the eq for total cos
An equation for the total cost is TC = 1500 + 5x
In this question, a canteen has fixed cost of $1500 per week.
A meal costs $5 each are sold at a fixed price of $9 each.
We need to write the equation for the total cost.
Let x be the number of individuals.
Let TC represents the total cost.
So, an equation for the total cost would be,
TC = 1500 + 5x
Therefore, an equation for the total cost is TC = 1500 + 5x

A box is filled with 12 red crayons, 5 blue crayons, and 7 yellow crayons.
A crayon is chosen at random from the box. Find the probability that it is a blue or a yellow crayon.
Write your answer as a fraction in simplest form.
Answer:
Red or blue crayon - 11/16
Step-by-step explanation:
Red crayon - 9/16
Blue crayon - 2/16
Red or blue crayon - 11/16
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
There are 24 total crayons in the box. You want to know the probability of picking a blue or yellow crayon. Since there are 7 yellow crayons and 5 blue you add those together and get 12. You now have your numerator in your fraction. There are also 12 red crayons12+12 = 24 and now you have your denominator. The fraction now reads 12/24. You simplify by dividing the top and bottom by 12 and get 1/2. Hope this helps.Point G is the center of the small circle. Point X is the center of the large circle. Points G, H, and X are all on line segment GX.
what should be the area of a new circle that has a line segment GX as the diameter
The area of a new circle that has line segment GX as its diameter is 121 pi cm² .
Suppose that,
The radius of the small circle (GH) = 10 cm.
The radius of the big circle (HX) = 12 cm.
We will add the line GH and HX to get the total length of line segment GX.
So, GX = GH + HX
= 10 + 12
GX = 22 cm.
So, the diameter of new circle will be equal to line segment GX as it is given in the question.
Then, the area of new circle = π r² ( r = radius)
Radius = D/2 = 22/2 (D = Diameter)
r = 11
Now, Area = π × 11²
= 121π cm²

The value of x in the angles is 14.
How to find angles when parallel lines are cut by transversal?When parallel lines are cut by a transversal, angle relationships are formed.
The angle relationships that are formed includes corresponding angles, alternate angles, vertical angle etc.
Therefore, the value of x can be found as follows;
m∠1 = m∠7 (vertical angles)
Therefore,
m∠7 = m∠15(corresponding angles)
Hence,
m∠1 = m∠15
m∠1 = 8x - 4
m∠15 = 6x + 24
Therefore,
8x - 4 = 6x + 24
8x - 6x = 24 + 4
2x = 28
divide both sides by 2
x = 28 / 2
x = 14

Determine whether the vectors in each pair are normal to each other. (6,-3) and (2,4).
Since their dot product is zero, then (6,-3) and (2,4) are normal to each other.
Step-by-step explanation:
Two vectors are said to be normal or perpendicular to each other if the result of their dot product is equal to zero.
These two vectors are also called orthogonal to each other.
Let u = (u₁, u₂) and v = (v₁, v₂), then the dot product u . v is defined as:
u . v = u₁v₁ + u₂v₂
To check whether the vectors are normal to each other, let us check their dot product.
The given vectors are: (6,-3) and (2,4).
Let u = (6, -3) and v = (2, 4), then,
u . v = 6 . 2 + (-3) . 4
= 12 + (-12) = 0

Rotation 90° counterclockwise around the origin
Translation 17 units right and 12 units up
The point after all the rotation and translation will become (17 - y, x + 12) from (x, y).
We need to first rotate the point 90° counterclockwise around the origin.
Let the point be (x, y)
When rotating a point 90° counterclockwise about the origin, the coordinate of the point (x, y) will become (-y, x). In other words, x and y will be switched and y will become negative.
Now, we need to translate the point 17 units right.
So, it means that the x - coordinate of the point will become x + 17
So, the point now becomes:
( -y , x ) = ( - y + 17 , x)
(17 - y, x)
Now we have to translate the point 12 units up.
So, we get that:
(17 - y, x + 12)
Therefore, the point after all the rotation and translation will become (17 - y, x + 12) from (x, y).

The left and right page numbers of an open book are two consecutive integers whose sum is 277. Find these page numbers.
The two page numbers are
(Use a comma to separate answers as needed.)
Answer:
138, 139
Step-by-step explanation:
You want the consecutive page numbers whose total is 277.
Consecutive numbersConsecutive integers differ by 1. If the lesser of two consecutive integers is represented by x, then the next one is (x+1). The sum of these two integers will be ...
x + (x +1) = 2x +1
We want to find the numbers whose sum is 277:
2x +1 = 277
2x = 276
x = 138
x+1 = 139
The two page numbers are 138, 139.
__
Additional comment
It is customary for the odd page number to be on the right when the book is open. Fortunately, this problem makes that be the case.
Therefore, two page numbers are 138, 139 of a left and right page numbers of an open book are two consecutive integers whose sum is 277.
What is integers?Positive numbers, negative numbers, and zero are examples of integers. 'Integer' is a Latin word that means 'complete' or 'completely'. This means that integers exclude fractions and decimals. In this article, we'll learn more about integers, their definition, and their properties.
All whole numbers & negative numbers are considered integers. This means that if we combine negative and whole numbers, we get a set of integers.
The difference between two consecutive integers is 1. The following integer is (x+1) if x is the lesser of two subsequent integers. These two integers' sum will be
x + (x +1) = 2x +1
So for 277 the equation will be
⇒ 2x +1 = 277
⇒ 2x = 276
⇒ x = 138
⇒ x+1 = 139

Find the value of 1.36 divided by 0.081
Answer: 16.7901
Step-by-step explanation: when dividing decimals, you need to make the divisor a whole number.
So, in this case you move the decimal point on 0.081 until it is a whole number.
then it would be 81 after moving the point 3 times to the right.
Now to make it even, you need to move the decimal point on 1.36: 3 times. You will then get: 1,360 divided by 81
And add back the decimal point once you divide.

For each function, find the inverse and the domain and range of the function and its inverse. Determine whether the inverse is a function. f(x)=(x-4)²
The inverse function returns the original value for which the output of a function was given.
The inverse of the function f(x) = (x - 4)² is f(x) = √x - 4
What is the inverse formula?The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.
An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.
Consider F(x) = y,
The x and y value is switched giving the necessary equation of
x = (y - 4)²
Then solve for y
√x = y - 4
simplifying the above equation, we get
y = √x - 4
