What is inequality?Inequality refers to the phenomenon of unequal and/or unjust distribution of resources and opportunities among members of a given society. The term inequality may mean different things to different people and in different contexts.
According to the question
Julia and her children went into a restaurant where ,
hamburgers (xx)= $7 each
tacos (yy) = $2.50 each.
Julia has $60 to spend and must buy a minimum of 14 hamburgers and tacos altogether.
i.e, xx + yy ≥ 14 ----------------------------(1)
7xx + 2.5yy ≤ 60 ----------------------(2)
from equation (1) and (2) graph attached ...
solving both equation
multiplying equation (1) with -7
-7xx + -7yy ≤ -98 ----------------(3)
now adding equation (3) and (2)
-7xx + -7yy ≤ -98
7xx + 2.5yy ≤ 60
= - 4.5yy ≤ -38
= 4.5yy ≥38
= yy ≥ 8.4
now ,
yy xx

What is the range of the function f(x) = |x| + 3?
{f(x) ∈ ℝ | f(x) ≤ 3}
{f(x) ∈ ℝ | f(x) ≥ 3}
{f(x) ∈ ℝ | f(x) > 3}
{f(x) ∈ ℝ | f(x) < 3}
{f(x) ∈ ℝ | f(x) ≥ 3} is the range of f(x) = |x| + 3
⇒ Range is in the y-axisWhen graphing the following equation shown below:
f(x) ≥ 3f(x) ∈ ℝ[ 3, ∞ ]Answer:
{f(x) ∈ ℝ | f(x) ≥ 3}
Step-by-step explanation:
The range of a function is the output values (y-values).
Absolute value is the distance of x from zero, so it is never negative. It is denoted by a bar on either side of the term.
Therefore, as |x| ≥ 0 then |x| +3 ≥ 3
Therefore, the range of the function is {f(x) ∈ ℝ | f(x) ≥ 3}

Answer:

Step-by-step explanation:
Sometimes these inscribed polygon problems respond nicely to a little geometrical thinking. The figure is symmetrical about the vertical line through the center of the square(s).
__
AnalysisThat line of symmetry divides the figure into halves that are twice as tall as wide. That same ratio applies to both the outer square and the inner (blue shaded) square.
In other words, a line from the center of the top segment through either bottom corner of the figure will pass through the corners of both squares. That line will have a slope of ±2, making it easy to find the coordinates of one of the lower corners of the shaded square.
__
System of EquationsAnalytically, we can write the equation of the right circle shown in the attachment as ...
x² +y² = 5²
and the equation of the line as ...
y = 2x +5
__
Solution of EquationsThen the x-value of the lower left corner will be found where these intersect.
x² +(2x +5)² = 25 . . . . . . substitute for y
x² +4x² +20x +25 25 . . . . eliminate parentheses
5x² +20x = 0 . . . . . . . . . . . . subtract 25
5x(x +4) = 0 . . . . . . factor
x = -4 or 0 . . . . . the x-coordinates of the points of intersection
The y-coordinate of the lower left point is ...
y = 2(-4) +5 = -3
__
Area of the SquareSince the top edge of the blue square has a y-coordinate of 0, this means the square is 3 cm on a side. Its area is ...
A = s² = (3 cm)² = 9 cm² . . . . area of the blue shaded square

Step-by-step explanation:

To cook fondant, sugar and water are heated to 230°F. Then the mixture
is cooled at room temperature before it is kneaded. If the cooked fondant
cools to 200°F in 15 minutes in a 68°F kitchen, how long will it take to
cool to 100°F? (Hint: Find the constant k first.)
Using the Newton's law of cooling, the time it takes to cool to 100°F is 116 mins.
Newton's law of coolingAccording to the Newton's law of cooling, the when an object is exposed to the surrounding it looses heat rapidly untill it is at a thermal equilibrium with the suurroundings.
Now;
T(t) = T(s) + (To - Ts)e^-kt
T(t) = temperature at time T
To = initial temperature
Ts = temperature of the surrounding
k = colling constant
t = time taken
200 = 68 + (230 - 68)e^-15k
200 = 68 + 162e^-15k
200 - 68/162 = e^-15k
ln(0.815) = -15k
k = ln(0.815)/-15
k = 0.014 min-1
Now;
100 = 68 + (230 - 68)e^-( 0.014t)
100 -68/162 = e^-( 0.014t)
0.198 =e^-( 0.014t)
ln(0.198) = -( 0.014t)
t = ln(0.198)/-0.014
t = 116 mins

What is the area of the base of the larger cylinder?
Enter your answer in the box.
An altitude is drawn from the vertex of an isosceles triangle, forming a right angle
and two congruent triangles. As a result, the altitude cuts the base into two equal
segments. The length of the altitude is 18 inches, and the length of the base is
17
inches. Find the triangle's perimeter. Round to the nearest tenth of an inch.
Answer:56.8 inches
Step-by-step explanation:
For perimeter we must find the lengths of the 2 diagonal sides of the triangle which are the same because it is isosceles.
the triangle is cut directly in half so both halves of the base are 17/2
17/2 = 8.5
solve through pythagoren theorum
altitude^2 + (half of base)^2 = (diagonal length)^2
18^2 + (8.5)^2 = (diagonal length)^2
324 + 72.25 = (diagonal length)^2
396.3 = (diagonal length)^2
[tex]\sqrt{396.3}[/tex] = diagonal length
diagonal length = 19.9
diagonal length + diagonal length + base = perimeter
19.9 + 19.9 + 17 = perimeter
56.8 inches = perimeter
1. According to the food label on a box cookies, each box has 16
servings and each serving contains 4 cookies. The weight of the
box of cookies is 1/2
kilograms. What is the weight of each
cookie?
Answer:
Step-by-step explanation:
Formula
Total number of cookies = number servings * number of cookies in serving
Givens
Number of servings = 16
Number of cookies in each serving=4
Total Mass = 0.5 kg
Solution
Total number of cookies = 16*4
Total number of cookies = 64
Total mass of box = # cookies * mass of 1 cookie
Total Mass of box = 0.5
# cookies = 64
0.5 kg = 64 * mass 1 cookie Divide by 64
0.5 / 64 = 64*mass 1 cookie/64 Compute
Answer: mass 1 cookie = 0.0078 kg
This question has 2 problems. I think this is the answer you should type in, but it is a mass, not a weight. Since the cookie is using weight for mass, and uses the units of mass, you have to do the same thing.
The units of the answer is not specified. Since the total mass is given in kg, then the units you use must be the same. However grams would be much more sensible. The answer would then be 7.8 grams.

Complete the table for each circle. Use paper to help you with your thinking
Help please
Answer:
written out in the explanation.
Step-by-step explanation:
Area of a circle = [tex]\pi r^{2}[/tex]
Circumference of a circle = [tex]2\pi r[/tex]
The radius is the center point of a circle to the edge of a circle. The diameter is a line from one edge of a circle to the opposite edge.
So, the radius is simply half of the diameter.
For circle A, the radius is 12. Therefore, the diameter is 24.
The circumference is 2·[tex]\pi[/tex]·12 ≈ 75.39822 inches. rounded, the circumference is 75.4 inches.
The area is [tex]\pi 12^{2}[/tex] ≈ 452.38934. rounded, the area is 452.39.
For B,
you have already solved the diameter and radius correctly, good job :). The steps for finding the circumference are the same as for circle A.
the circumference is 2·[tex]\pi[/tex]·6 ≈ 37.69911. rounded, the circumference is 37.7 inches.
the area is [tex]\pi 6^{2}[/tex] ≈ 113.09734. rounded, the area is 113.1.
For C,
the circumference is 12. We can use the circumference equation to solve for the radius.
12 = [tex]2\pi r^{2}[/tex]
divide both by 2[tex]\pi[/tex]
7.63943726841 = [tex]r^{2}[/tex]
square root of 7.63943726841 = 2.76395319577
radius = 2.76395 inches. rounded, the radius is 2.8 inches.
so, radius ·2 = 5.52790639154.
meaning diameter = 5.52791. rounded, the diameter is 5.5 inches.
the area is [tex]\pi 2.76395^{2}[/tex] ≈23.99994. rounded, the area is 24.

In quadrilateral two angles are equal. The third angle is equal to the sum of the two equal angles. The fourth angle is 60degrees less than twice the sum of the other three angles. Find the measures of the angles in the quadrilateral.
Answer: 35, 35, 70, and 220
Step-by-step explanation:
– Let x = size of one of the two equal angles
The sum of angles in a quadrilateral is 360:
360 = x+ x + ( x+x ) x (2( x+ x+ x+x ) – 60)
360 = 4 + 2(4 ) – 60
360 = 4 + 8 – 60
360 = 12 – 60
12x = 420
= 35
Substituting x for 35, will get: 35, 35, 70, 220
The values of the angles are 35°, 35°, 70° and 220°
