Hector's school is holding a fitness challenge. Students are encouraged to exercise at least 2 1/2 hours per week. Hector exercises about the same number of hours each week. During a 4-week period, he exercises for 11 1/2 hours. Hector wants to compare his exercise rate with the fitness challenge rate.
Hector outperformed the challenge rate as he exercised 2.88 hours a week.
It is best to convert the mixed fraction to decimals for easier calculation.
The students are encouraged to exercise 2¹/₂ hours per week. In decimals this is:
= 2 + ¹/₂
= 2 + 0.5
= 2.5 hours per week
In the 4 week period, Hector exercised 11¹/₂ hours which is:
= 11 + ¹/₂
= 11 + 0.5
= 11.5 hours
The number of hours he exercised per week is:
= Number of hours in total / Number of weeks
= 11.5 / 4
= 2.88 hours per week
When compared to the fitness challenge rate, we can conclude that Hector outperformed the challenge rate

A unit rate is a rate at which the the comparison is one unit.
Yes, a unit rate is a rate at which the the comparison is one unit.
A unit rate is a ratio between two separate units with one as the denominator.
Examples include miles/hour, kilometers/hour, meters/sec, salaries/month, etc. The most fundamental and historically significant field of mathematics is arithmetic, which is also the one we use the most frequently in daily life. This subject is all about mathematical procedures and problems centered on numbers.
We actually solve mathematical puzzles during our daily activities, whether we mean to or not. For instance, whether buying fruits or vegetables, engaging in other transactions, or determining how quickly something will happen, etc.
When comparing two different kinds of numbers with distinct units, a rate is a ratio that is employed. The unit rate, on the other hand, shows how many units of one quantity are equal to one unit of another. When the denominator of a rate is 1, we refer to it as a unit rate.

Given that,
A rectangular field has a perimeter of 150m The field is 15 meters longer than it is wide. The width of the field is x meters.
The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
The area of the rectangle = length * width
150 = 15 * x
x = 150 / 15
x = 10

f(x)=|x|+5 horizontal shrink of factor 3
The function that models the horizontal shink of f(x) by a scale factor k = 3 is:
g(x) = |3*x| + 5
How to apply a horizontal shrink to the given function?Here we want to apply a transformation to a given function where the transformation is a shrink.
For a function f(x), a horizontal shrink (or compression) of scale factor K is written as:
g(x) = f(k*x)
In this case we have the absolute value function:
f(x)= |x| + 5
And we want to apply an horizontal shrink of scale factor k = 3, so we will have a new function defined as:
g(x) = f(3*x)
If we replace f(x) by the function above we will get:
g(x) = f(3*x) = |3*x| + 5
So we conclude that the transformed function is just:
g(x) = |3*x| + 5

The Christensen family's kitten weighs 147
ounces. Write the weight of the kitten in pounds
and ounces.
The weight of Christensen's family's kitten is 9 pounds 3 ounces.
The imperial unit of mass or weight measurement is the pound. The symbols for pounds are lb and lbm. A kilogram weighs 0.4535 pounds. The term "pound" has Germanic roots.
In the conventional system of measurement, a pound is a unit of weight. 16 ounces make up one pound.
Therefore,
We know that 1 pound = 16 ounces
16 ounces = 1 pound
Dividing each side by 16.
( 16 / 16) ounces = ( 1/16 ) pound
1 ounce = ( 1/16 ) pound
Multiplying each side by 147,
1 ounce × 147 = ( 1/16 ) × 147 pound
147 ounces = ( 147 / 16 ) pounds
147 ounces = 9.1875 pounds
147 ounces = 9 + 0.1875 pounds
147 ounces = 9 pounds 3 ounces
The weight of the kitten is 9 pounds 3 ounces.

1. Mrs. is selling tickets to a school carnival fundraiser. Adult tickets are $5 and student tickets
are $3. At the end of the fundraiser, she had made $521 and had sold a total of 145 tickets. How
many student tickets did she sell?
Taking into account the definition of a system of linear equations, she sold 102 student tickets.
System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.
This caseIn this case, a system of linear equations must be proposed taking into account that:
A: number of adults tickets sold.S: number of students tickets sold.Knowing that:
Adult tickets are $5 and student tickets are $3. At the end of the fundraiser, she had made $521 and had sold a total of 145 tickets.the system of equations to be solved is
[tex]\left \{ {{A+S=145} \atop {5A+3S=521}} \right.[/tex]
Of the multiple methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable A from the first equation:
A= 145 - S
Replacing this expression in the second equation:
5(145 - S) + 3S= 521
5×145 - 5S + 3S= 521
725 - 5S + 3S= 521
-5S + 3S= 521 - 725
-2S= -204
S= (-204)÷(-2)
S= 102
Finally, she sold 102 student tickets.

Which line is perpendicular to 3 x+2 y=6 ?
(A) 4x - 6y = 3
(B) y = -(3/2)x + 4
(C) 2x + 3y = 12
(D) y = (3/2)x+1
The equation of the line 3x + 2y = 6 is perpendicular with the equation of the line (A) 4x - 6y = 3.
Two lines are perpendicular with each other if they form right angle at the point of their intersection. The slopes of perpendicular lines are negative reciprocal of one another.
The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.
In an equation in standard form, ax + by = c, the slope, m, of the line is equal to a/b. On the other hand, in an equation in slope-intercept form, y = mx + b, m is the slope.
Determine the slope of the given line and each given choices:
3x + 2y = 6
m = a/b = 3/2
(A) 4x - 6y = 3
m = a/b = 4/-6 = -2/3
(B) y = -(3/2)x + 4
m = -3/2
(C) 2x + 3y = 12
m = a/b = 2/3
(D) y = (3/2)x + 1
m = 3/2
Since the slope of the given line is 3/2, taking its negative reciprocal, the slope of the perpendicular line should be -2/3. The line with the slope of -2/3 is (A) 4x - 6y = 3.
Hence, (A) 4x - 6y = 3 is perpendicular with 3x + 2y = 6.

A Florida orange juice plant started producing a juice blend, it must be within 0.78 fluid ounces of the advertised 32 fluid ounces on the label. If x represents the volume, write an equation to model the maximum and minimum volumes and determine the minimum volume in a bottle.
|x - 32| = 0.78
|x + 32| = 0.78
|x - 0.78| = 32
|x + 0.78| = 32
The correct equation is:
|x - 32| = 0.78
In this case, x represents both the maximum and minimum accepted volumes.
How to writhe an equation that models the maximum and minimum volumes?We know that the mean volume is 32 fluid ounces, and the acceptable error is 0.78 fluid ounces.
Then the maximum acceptable volume is 32 + 0.78 fluid ounces, and the minimum acceptable volume is 32 - 0.78 fluid ounces.
This means that the absolute value of the difference between x, the volume, and 32, must be equal to 0.78
This is written as:
|x - 32| = 0.78
