Step-by-step explanation:
if the price of viva increases from $2.50 to $2.60 and the price of brawny is unchanged, the sales of brawny will?
The sales of Brawny will remain unchanged, as the amount of Brawny has not changed.
Price is one of the factors that influence the demand and sales of any product. Therefore, when the price of a product changes, the sales of that product may be impacted. However, when the price of one product changes, the sales of another product that has not changed in price may remain unaffected. In this case, since the price of Viva has increased from $2.50 to $2.60, while the amount of Brawny has remained unchanged, the sales of Brawny will likely remain unchanged.

According to the information in the graph, the blend of foods that satisfies the requirements at the minimum cost is option A because it would be worth only 10.
How to calculate which is the cheapest blend of food option?To calculate the cheapest blend of food option, we must take into account the amounts of each element (carbohydrate, protein, fat) and identify how many units of each blend we need to cover the minimum quota.
Based on the above information, to identify the blend units we need to cover the minimum quota we must find it by multiplying each of the elements by the number of times we would need to meet the minimum requirement. Once we identify the quantities we need, we must multiply the price by the number of units we need.
Following the previous procedure, we can identify that the best option would be blend A because we must buy it 5 times to cover the minimum requirements. Additionally, its value would be 10, while the others would have a higher value.

An equation of a line is shown. A second line is perpendicular to the given line and passes through the point (0,1).
Which is the equation of the perpendicular line?
The equation of the perpendicular line is (c) y = 2/9x - 1
How to determine the perpendicular line equation?From the question, we have the following parameters that can be used in our computation:
y + 17 = -9/2(x - 3)
Also, from the question;
We have the following points
Point = (0, -1) i.e. (x, y) = (0, -1)
The equation of a line can be represented as
y - y₁ = m(x - x₁)
Where
Slope = m
By comparing the equations, we have the following
m = -9/2
This means that the slope is -9/2
The slopes of perpendicular lines are opposite reciprocals
This means that the slope of the other line is 2/9
The equation of the line is then calculated as
y = m(x - x₁) +y₁
Where
m = 2/9
(x₁, y₁) = (0, -1)
So, we have
y + 1 = 2/9(x - 0)
Evaluate
y = 2/9x - 1
Hence, the line has an equation of y = 2/9x - 1

Researchers are investigating the effect of pH level in water on the breeding habits of the moon jellyfish. As part of a laboratory experiment, they will randomly assign one of three treatments, low pH, medium pH, or high pH, to the water in the tanks that hold the jellyfish.
Which of the following is the best reason for the random assignment of a treatment level to an experimental unit?
A. Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects. B. Randomization will make up for improper experimental design, data collection, and analysis.
C. Randomization makes the analysis easier since the data can be entered into the computer in any order. D. Randomization is required by statistical consultants before they will analyze the experiment.
E. Randomization means that the experiment would not need to be replicated.
In order to prevent such factors from influencing the treatment's outcomes, randomization tends to reduce the impact of uncontrollable variables like water temperature.
What are variables?
A variable in mathematics is a symbol that designates a mathematical object. A variable can represent any of the following: a number, a vector, a matrix, a function, its argument, a set, or an element of a set. An unknown numerical value in an equation or algebraic expression is represented by a symbol (often a letter) in algebra. A variable is, to put it simply, a quantity that may be altered and is not fixed. Because they make up a significant portion of mathematics, variables are crucial.

Savannah takes a car to a title loan business to borrow some money. Savannah is given $2,900.00. She must pay back the $2,900.00 in addition to a $1,375.00 fee in 8 months.
What simple interest rate is she
being charged?
Round to the nearest tenth of a percent and don't forget to include a percent sign, %, in your answer.
Savannah is being charged a simply interest rate of ______.
Step-by-step explanation:
To find the simple interest rate that Savannah is being charged, we can use the formula for simple interest:
I = P * r * t
where I is the total interest paid, P is the principal (the amount borrowed), r is the interest rate, and t is the time period over which the interest is paid.
Since Savannah must pay back the $2,900.00 principal plus a $1,375.00 fee, the total interest paid is $1,375.00. The time period is 8 months, which is equal to 8/12 = 2/3 of a year. Substituting these values into the formula and solving for r, we get:
$1,375.00 = $2,900.00 * r * (2/3)
r = $1,375.00 / ($2,900.00 * (2/3)) = 0.1429
This is the interest rate that Savannah is being charged. To express this rate as a percentage, we can multiply it by 100% to get:
r = 0.1429 * 100% = 14.3%
Therefore, Savannah is being charged a simple interest rate of approximately 14.3%.

The value of dc/dt due to changes in p and c variables is 0.364.
The positive variables p and c change with respect to time 1. The relationship between p and c is given by the equation p^2 = (20-c)^3. Now the dp/dt value is 41 and c is 15.
Differentiate the given equation to obtain the following:
2p dp/dt = 3(20-c)^2 dc/dt
Substitute the given values in the equation to obtain the following:
2p (41) = 3(20 - 15)^2 dc/dt
Simplify the equation to obtain the following:
82 = 225 dc/dt
Divide both sides of the equation by 225 to obtain the following:

The rate at which the area of the forest is increasing, in square kilometers per decade, is 0.0041.
What does the rate of change mean?
How quickly one variable changes in relation to another is known as the rate of change. Speed is an example of a "rate of change." Speed is defined as the rate at which the distance to an object varies in relation to the time spent.
It is given that there are 640 acres in 1 square mile which can also be written as 640 acres= 1[tex]mi^2[/tex].
The area of forest is increasing at a rate of 1 acre/decade.
It is given that 1 km= 0.62mi
By squaring on both sides we will get 1 [tex]km^2[/tex] = 0.3844 [tex]mi^2[/tex].
The rate at which the area of forests is increasing in square kilometers per decade is

at what time t is the instaneous velocity equal to the averge equal to the equal to the average velocity of the bug on 0,6 is the bug speeding up or slowing down at t
At t = 0.6, the instantaneous velocity of the bug is equal to the average velocity of the bug on [0,6], so the bug is neither speeding up nor slowing down.
The instantaneous velocity of a bug at any particular moment in time is the rate at which the bug is changing its position. The average velocity of the bug over a particular interval (in this case, [0,6]) is the average rate at which the bug changes its position over the entire interval. To compare the instantaneous velocity to the average velocity, the two velocities need to be measured at the same time.
At t = 0.6, the instantaneous velocity of the bug is equal to the average velocity of the bug on [0,6]. That means that the bug is neither speeding up nor slowing down.

A triangle has its base doubled and its
height increased by 30%. By what percent
has the area of the triangle increased?
(A) 130%
(B) 160%
(C) 230%
(D) 260%
Let the base and height of triangle be b and h.
area of triangle= 1/2*base*height
Area of triangle= bh/2
Now Base is Doubled and Height increase by 30%
New base = 2b
New height = h×130/100 = 13h/10
New area = 1/2 × 2b × 13h/10
New area = 13bh/10
Area increased = New area - area
Area increased = 13bh/10 - bh/2
Area increased= 13bh-5bh/10
Area increased= 8bh/10
Area increased= 4bh/5
ratio increased in % = Area increased/ Old Area × 100
ratio increased in % = 4bh/5 ÷ bh/2 × 100
ratio increased in % = 4/bh × 2/bh × 20
ratio increased in % = 8×20
ratio increased in % = 160%
