A rate is a ratio comparing quantities of different items. A unit rate is a rate with 1 in the denominator.
How to calculate unit rate?A rate is a ratio comparing quantities of different items. A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.
Examples of How to Find Unit Rate or Unit Price
We want to know the price per apple unit so we set up a ratio with the number of apples in the denominator. The total price goes in the numerator. So the fraction is 1.80/3.Complete the division: 1.80 ÷ 3 = .60. You can conclude that the per apple price unit rate is $0.60/1. Ryan paid a unit price of $0.60 per apple (60 cents per 1 apple = .60/1).We want to know the number of mugs made per hour unit so we set up a ratio with hours in the denominator.

By using the correlation coefficients, it is found that the two conclusions which the researcher can make from the given data are:
The relation is positive, which is, the higher the proportion of calories from sweeteners in their diets, the higher the mortality.The relationship is not strong.What is the Correlation Coefficient?The correlation coefficient is a statistical measure of the strength of a linear relationship among two variables. Its assuming values can range from -1 to 1. If it is positive, the relation is positive, which is, they are direct proportional. And if it is negative, they are inverse proportional. If the absolute value of the correlation coefficient is greater than 0.6, it means the relationship is strong.
In this case, since the correlation is 0.486, thus, the conclusion is that the relation among the variables is positive, that means the higher the proportion of calories from sweeteners in the diets, the higher the mortality.

A trucking company sets up contracts with various manufacturing companies to ship their freight. One contract has the following points: A charge of 6.5% of the total value of the freight for each delivery. A charge of $70 per delivery regardless of the amount of freight. Your responsibility is to determine the lowest values of combinations of total freight value and number of deliveries each month that will be necessary in order for the trucking company to make AT LEAST $102,000 each month.
Using concept of linear inequality, number of least deliveries is 30 and value of freight is $60000.
What are linear inequalities?
Inequality represents the mathematical expression in which both sides are not equal. If the relationship makes the non-equal comparison between two expressions or two numbers, then it is known as inequality in Maths. In this case, the equal sign “=” in the expression is replaced by any of the inequality symbols such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤) or not equal to symbol (≠). The different types of inequalities in Maths are polynomial inequality, rational inequality, absolute value inequality.
The symbols ‘<‘ and ‘>’ express the strict inequalities and the symbols ‘≤’ and ‘≥’ denote slack inequalities. A linear inequality seems exactly like a linear equation but there is a change in the symbol that relates two expressions.
e.g. y>x+2
Now,
Given charge of $70 per delivery and A charge of 6.5% of the total value of the freight for each delivery and least amount is $102,000.
Let only one delivery is possible per day and no. of deliveries=n
amount of each freight=x
Therefore,
Linear inequality will be n(6.5/100**x+70)>102000
So least values of n and x will be
n=30 and x=$60000
Hence,
number of least deliveries is 30 and value of freight is $60000.

Given the function g of x is equal to the quantity 2 x squared plus 4 x plus 6 end quantity over the quantity x plus 4 end quantity determine the equation for the slant asymptote. (2 points)
y = −2x + 4
y = 2x − 4
y = 2x + 4
y = 2x + 12
The equation for the slant asymptote of the given function is y = 2x - 4.
Option (B) is correct.
What is the slant asymptote of the function?
A slant asymptote of a function is a line that the function approaches, but never touches or crosses. It is a type of asymptote that occurs when the degree of the numerator of a rational function (a function that can be written as the ratio of two polynomials) is greater than the degree of the denominator.
To determine the equation for the slant asymptote of a rational function (a function that can be written as the ratio of two polynomials), we need to look at the degree (the highest power of x) of the numerator and the degree of the denominator.
The function g(x) = (2x^2 + 4x + 6) / (x + 4)
The degree of the numerator is 2 and the degree of the denominator is 1, since the x^2 is the highest power of x in numerator and x is the highest power of x in denominator.
Since the degree of the numerator is greater than the degree of the denominator, the slant asymptote will have the same degree as the numerator, which is 2.
To find the equation of the slant asymptote, we divide the numerator by the denominator using the long division method and get
2x + 2 - (x + 2)/(x + 4)
The equation of the slant asymptote will be the result of the long division, which is 2x - 4
Hence, the equation for the slant asymptote of the given function is y = 2x - 4

Given the function h(x)=-x²+4x+12, determine the average rate of change of the function over the interval -1≤x≤8
The average rate of change of the function over the interval -1≤x≤8 is -3.22.
How do you determine the average rate?The average rate of change of a function over an interval is given by the formula (f(b) - f(a)) / (b - a) where f(x) is the function, a is the starting point of the interval, and b is the ending point of the interval.
In this case, the function is h(x) = -x² + 4x + 12, the interval is -1≤x≤8.
Plugging in the values we have:
Average rate of change = (h(8) - h(-1)) / (8 - (-1)) = (h(8) - h(-1)) / 9
h(8) = -8² + 4(8) + 12 = -64 + 32 + 12 = -20
h(-1) = -1² + 4(-1) + 12 = 1 - 4 + 12 = 9

What would you make the size of the hypotenuse of a right tria gle to make if its other two size measure 2 and 5 cm?
a. 7 squared.
b. 29 squared.
C. 29.
d. 29 squared by 3.
Answer: To find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the legs).
So, if the legs of the right triangle measure 2 cm and 5 cm, the hypotenuse c can be calculated as follows:
c² = a² + b²
c² = 2² + 5²
c² = 4 + 25
c² = 29
Therefore, the length of the hypotenuse c is the square root of 29.
c = √29
The answer is c = √29 which is the only one that is not squared, So the answer is (C) 29.

MODELING WITH MATHEMATICS: The function f(t)=-16t^2+10 models the height (in feet) of an object t seconds after it is dropped from a height of 10 feet on Earth. The same object dropped from the same height on the moon is modeled by g(t)=-8/3t^2+10.
Describe the transformation of the graph of f to obtain g.
The graph of g is a horizontal stretch by a factor of (blank) of the graph of f. Round your answer to the nearest hundredth.
From what height must the object be dropped on the moon so it hits the ground at the same time as on Earth? Round your answer to the nearest hundredth.
The object must be dropped from a height of (blank) feet.
The transformation of the graph of f to obtain g is described as follows:
The graph of g is a vertical compression of the graph of f by a factor of 6 units.
The object must be dropped at a height of 1.66 feet from the moon so it hits the ground at the same time as on Earth,
What is the transformation?The functions in the context of this problem are given as follows:
f(t) = -16t² + 10.g(t) = -8/3t² + 10.The multiplier that was applied to function f(t) to obtain function g(t) is given as follows:
-16x = -8/3
16x = 8/3.
x = 8/48
x = 1/6.
The leading coefficient was divided by 6, meaning that the graph of g is a vertical compression of the graph of f by a factor of 6 units.
When does the object hits the ground?The object hits the ground when the output of the quadratic function assumes a value of zero.
For the Earth, we have that the time to hit the ground is obtained as follows:
-16t² + 10 = 0
16t² = 10
t² = 5/8
[tex]t = \sqrt{\frac{5}{8}}[/tex]
t = 0.79 seconds.
For the Moon, the function is given as follows:
g(t) = -8/3t² + h.
In which h is the initial height.
We want that g(t) = 0 when t = 0.79, hence the initial height is obtained as follows:
0 = -8/3(0.79)² + h
h = 8/3(0.79)²
h = 1.66 feet.
