A 2010 u.s. census bureau report indicated there are 4,229,138 residents of indiana aged 25 and older. what percentage of the residents aged 25 and older have a degree if there are 326,036 residents with an associate's degree, 623,200 with a bachelor's degree, and 348,807 with either a graduate or professional degree? write your answer as a percent rounded to the nearest whole number.
Among the 4,229,138 residents of Indiana aged 25 and older, the percentage of the residents aged 25 and older that have a degree is 31 %.
Percentage, which was adapted from the Latin word "per centum", which means "by the hundred", is a fraction or a ratio in which the value of whole is always 100. It is represented by the symbol "%".
The formula to get the percentage is:
Percentage = (Value / Total Value) × 100
Getting first the total value of the degree holders: 326,036 have an associate's degree, 623,200 have a bachelor's degree, and 348,807 have either a graduate or professional degree
residents with degree = 326,036 + 623,200 + 348,807
residents with degree = 1,298,043
If the total value of the residents aged 25 and older is 4,229,138 and among them, 1,298,043 have a degree, getting its percentage using the formula:
Percentage = (Value / Total Value) × 100
Percentage = (1,298,043 / 4,229,138) × 100
Percentage = (0.3069285041) × 100
Percentage = 30.69 %
Rounding off to the nearest whole number,
Percentage = 31 %

Find the area of parallelogram ABCD given mA = 30 and the following measures. AB = 6ft ; AX = 3 [square root] 3, A = ?
The area of the given parallelogram is: 9√3 sq. feet.
What is a parallelogram?A parallelogram is a simple quadrilateral with two sets of parallel sides in Euclidean geometry. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.
Area of a parallelogram = Base of the Parallelogram * Height
Now, given:
A parallelogram ABCD,
AB = 6 feet, AX = 3√3. Angle A = 30°
To find: Area of the Parallelogram ABCD.
Finding: Here, AB = 6 feet = base
For height,
Height = perpendicular distance from X to AB
= AX(sinA)
Height = 3√3 (sin30) = 3√3 / 2
Thus, area of the parallelogram = [tex]\frac{3\sqrt{3}}{2}\times6= 9\sqrt{3}sq. feet.[/tex]
Hence, The area of the given parallelogram is: 9√3 sq. feet.

Using linear functions, it is found that:
Plan B is better than Plan A when Curt's sales are more than $21,000.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For the functions in this problem, we have that:
The salary is the intercept.The commission is the slope.Hence the functions are given as follows:
A(x) = 1050 + 0.1x.B(x) = 1350 + 0.15(x - 9000).Plan B is better when:
B(x) > A(x).
Hence:
1350 + 0.15(x - 9000) > 1050 + 0.1x
0.05x > 1050

The rows of small jars of salsa are increased by 4 times.
The rows of ounces of salsa are increased by 32 times.
The pattern in the column of the table is
y = 8x
Therefore x = 4 then y = 8(4) = 32
x = 8 then y = 8(8) = 64
x = 12 then y = 8(12) = 96
x = 16 then y= 8(16) = 128.
x = 20 then y = 8(20) = 160.
The pattern in the column of the table is
y = 8x
Therefore x = 4 then y = 8(4) = 32
x = 8 then y = 8(8) = 64
x = 12 then y = 8(12) = 96
x = 16 then y= 8(16) = 128.
x = 20 then y = 8(20) = 160.
The relationship between ounces of salsa and small jars of salsa using a unit rate is
4 ounces = 1 serving
y = 4x
If x = 1 then y = 4
If x = 2 then y = 4(2) = 8
If x = 3 then y = 4(3) = 12
If x = 4 then y = 4(4) = 16
If x = 5 then y = 4(5) = 20
The relationship using the unit rate is

For 1 medium jars of salsa = 48/4 = 12 ounces.
1 medium jar of salsa = 12 ounces.

Call bag contains six red tiles and 15 yellow towels. lelia removes two red towels how many yellow tiles should she remove so that the ratio of red tiles to yellow towels in the bag stays equivalent to 6:15
5 yellow tiles should be removed.
The original ratio of red tiles to yellow tiles as per the question :Ratio = 6:15. Now, after removal of red tiles, the numerator of ratio will become = 6 - 2. The numerator of new ratio will be 4. For yellow tiles, let the number of yellow tiles removed be x. So, the denominator or new number of yellow tiles will be 15 - x.
Now, relating the two ratio -
6:15 = 4:(15 - x)
Performing cross-multiplication to find the value of x.
6 × (15 - x) = 4 × 15
Performing multiplication on both the Left Hand Side and Right Hand Side
90 - 6x = 60
6x = 90 - 60
Performing subtraction to find the value of x
6x = 30
x = [tex]\frac{30}{6}[/tex]
