We need to find how much water Ella needs to make the different concentrations of syrups. The solution will be for 1.5%, we need 32.83 lbs of water.
How to explain the concentration?The percentage in the concentration tells us how much in the mixture is sugar.
So for example, in the 50% syrup, we have a 50% of sugar, meaning that half of it is sugar, and we have 0.5 lbs of sugar, so we need to add the same amount of water, 0.5 lbs of water.
For the 1.5% syrup, this will be:
= (0.5 - 0.5 × 0.015) / 0.015
= 32.83 lbs

All sides of a lawn are expanded by the same amount so that it’s dimension are now 100 feet by 60 feet. If x is the same amount of length added to each side, write a function of x giving the length of each of the original sides. Use these functions to make a function for the area of the original lawn.
The function of x giving the length of each of the original sides would be [tex](x + 100) * (x + 60) = x^2 + 160x + 6000[/tex].
What is Function of x?
A function is a formula that expresses one variable in terms of another. The statement "y is a function of x" (denoted y = y(x)) states that y changes depending on the value of x.
The original length of each side of the lawn can be represented by the function x + 100, and the original width can be represented by the function x + 60.
To find the area of the original lawn, we can multiply the length and width functions.
So, the function for the area of the original lawn is:
[tex](x + 100) * (x + 60) = x^2 + 160x + 6000[/tex]
This is a quadratic function in x, whose leading coefficient is 1, and the value of x is the same amount of length added to each side of the lawn.
Hence, The function of x giving the length of each of the original sides would be [tex](x + 100) * (x + 60) = x^2 + 160x + 6000[/tex].

(e) (i) Using a scale of 2cm to represent 5 units on each axes, show, by shading the unwanted regions, the set of points satisfying the three inequalities in parts (b), (c) and (d). [3] (ii) Calculate the maximum number of rabbits the farmer can buy. [2]
Answer: (e) (i) To represent the inequalities graphically on a coordinate plane, you can use a scale of 2cm to represent 5 units on each axis. To shade the unwanted regions, you can start by drawing the coordinate plane and labeling the x and y axes. Then, you can graph the inequalities by plotting the lines and shading the regions that do not satisfy the inequalities.
(b) 2x + 3y ≤ 30
This inequality represents a line with the equation 2x + 3y = 30. You can graph this line by plotting a few points and then drawing a straight line through them. The points that are on or below the line satisfy the inequality.
(c) x - 2y ≥ -10
This inequality represents a line with the equation x - 2y = -10. You can graph this line by plotting a few points and then drawing a straight line through them. The points that are on or above the line satisfy the inequality.
(d) y ≤ -2x + 10
This inequality represents a line with the equation y = -2x + 10. You can graph this line by plotting a few points and then drawing a straight line through them. The points that are on or below the line satisfy the inequality.
The set of points that satisfy all three inequalities is the area that is not shaded in the graph.
(ii) To find the maximum number of rabbits the farmer can buy, we need to find the coordinates of the vertex of the feasible region.
The coordinates of the vertex of the feasible region is (x,y) the point where the line 2x+3y=30 and x-2y=-10 intersects.
We can substitute the x-2y=-10 into the 2x+3y=30 equation
2x+3y=30
2x+3y+2y=-10
2x+5y=-10
x=-5y+10
substituting this into one of the equation we have
2(-5y+10)+3y=30
-10y+20+3y=30
-7y=10
y= -10/7
substituting this into x = -5y+10 we have
x = -5(-10/7)+10 = 15
the maximum number of rabbits the farmer can buy is 15
Step-by-step explanation:
Choose the inequality that matches the graph below.
Answer:
X ≤ -1
How do we know this?
Well, if x = the value of any number in the graph, we can see that it can be equal to negative one, or less than -1, meaning we use the symbol ≤.
Consider the function g(x)=6cos(7x+22).
How much must x increase by for 7x+22 to increase by 2π?
After the increment in the function the value of x is -2.25
In math the term function is denoted as a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Here we know that the function g(x)=6cos(7x+22), x increase by for 7x+22 to increase by 2π.
In order to calculate the value of x in the function, we have to equate the value of function with 2π.
Then we get,
=> 7x + 22 = 2π
When we solve the equation for x then we get,
=> 7x = 2π - 22
=> x = (2π - 22)/7
When we simplify this one then we get the value of x as,
=> x = 0.285π - 3.14
=> x = 0.89 - 3.14
=> x = -2.25

Mike saves $2,000 at a yearly simple interest rate of 2%, he earns $280 in interest for how many years did he save this money
The number of years that he save this money is 7 years
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.
Simple Interest = (Principal × Rate × Time) / 100
Where P is the principal, R is the rate of interest, and T is the time.
Given;
Mike saves $2,000 at a yearly simple interest rate of 2%;
Money he earns in interest= $280
Then the number of years;
$280 = ($2,000 x 2 x T) / 100
$28,000 = $4,000 x T
T = $28,000 / $4,000
T = 7 years

Willow is driving on the freeway. She just passed mile marker 325. The fastest she will drive is 75 miles per hour, though, there is a bit of traffic that might slow her down a bit, but she doesn’t know exactly how much. The mile markers are increasing on her route.
The expression 325 + 2y represents what mile marker she’s at after 2 hours, depending on traffic. Which inequality describes the mile marker she would be at this point?
The inequality describes the mile marker she would be at this point is:
325 + 2y ≤ 475
Now, According to the question:
Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have,
The fastest driving speed of Willow is 75 miles per hour,
There is a bit of traffic on her route that might slow her speed down,
So, the inequality which represents the speed of the willow is:
y ≤ 75
Hence, the inequality which represents the speed of the driving of willow is y ≤ 75.
Now, the expression 361 + 2y represents what mile marker he is at after 2 hours. We know that the fastest he will drive is 75, so we could replace y=75 in the last expression to know what mile marker he would be seeing at that point. This is:
325 + 2(75) => 325 + 150 = 475

Justgive me the equations
The time in years for which the values are the same is given as follows:
7.25 years.
How to obtain the models?A decaying exponential model is given as follows:
y = a(1 - r)^t.
For which:
a is the initial value.r is the decay rate, as a decimal.The parameters for this problem are given as follows:
a = 56000, r = 0.12.
Hence the exponential model is given as follows:
y = 56000(0.88)^x.
The linear model is given as follows:
y = b - mx.
In which:
b is the initial value.m is the yearly depreciation rate.The parameter values for this problem are given as follows:
b = 56000, m = 56000/12 = 4666.67.
Hence the linear model is:
y = 56000 - 4666.67.
The point of intersection of the two graphs is at a time of 7.25 years.

The Interquartile range of the given set is 1.5.
What is Interquartile range ?
The variation between the third and first quartiles is defined by the interquartile range. The numbers that partition the entire series into four equal sections are known as quartiles. There are therefore 3 quartiles. The lower quartile is represented by the letter Q₁, the higher quartile by the letters Q₁, and the middle quartile by the letter Q₃.
Given set : 81, 82, 83, 83, 84, 84, 84, 85
Here, It is already in increasing order but the number of values is 8 which is even.
So, Q₁ part = 81, 82, 83, 83
Q₁ will be the median of 82 and 83.
So, Q₁ = (82+83)/2
= 82.5
Similarly, Q₃ part =84, 84, 84, 85
So, Q₃ will be the median of 84 and 84.
hence, Q₃ = (84+84)/2
= 84
We know that, Interquartile range = Q₃ - Q₁
= 84 - 82.5
= 1.5
