What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Here,
$5 for cleaning,
as she completed before 6 PM,
=5+20%*5
=5+1
=$6
Bridget's mother gave her $6 in total, with an additional $1 for cleaning before 6 o'clock.

In triangle efg and triangle yxz, angle x and angle e are congruent to angle y. If angle e = 62 degrees and x = 80 degree, what is the measure of angle Z
The measure of the angle ∠Z is 38°.
We are given two triangles. The vertices of the first triangle are E, F, and G. The vertices of the second triangle are Y, X, and Z. The angle ∠F is congruent to the angle ∠X. The angle ∠E is congruent to the angle ∠Y. The measures of the angles ∠E and ∠X are 62° and 80°, respectively. We need to find the measure of the angle ∠Z. The measure of the angle ∠Y must be equal to the measure of the angle ∠E.
∠Y = ∠E = 62°
Now, in the triangle ΔYXZ, we will use the angle sum property. The sum of all the angles in a triangle is equal to 180°.
∠Y + ∠X + ∠Z = 180°
62° + 80° + ∠Z = 180°
∠Z = 180° - (62° + 80°) = 180° - 142° = 38°

One piece of statistical evidence used against ms. Gilbert was a low p-value for the pattern of death observed on her shifts. What does this p-value mean and what is the relevance of the p-value to the trial?.
The level of marginal significance inside a statistical hypothesis test, or P-value, represents the likelihood that a particular event will occur.
P-value;
The likelihood of getting a result that is equivalent to or more extreme than what was actually seen, under the null hypothesis, is what is meant by the term "P value." The probability (P) indicator indicates the likelihood that any observed variation between groups is the result of chance.
Here,
The statistical test's extremely low p-value indicates that the null hypothesis must be accepted, and the conclusion that Gilbert is guilty is based on the fact that Gilbert's existence is dependent on the shift deaths.
Relevance of p-value to the trial;
The p-value evaluates the agreement between the trial's actual outcomes and the "pure chance" explanation for them. When the only differences between groups A and C are the result of chance, a p-value of 0.002 favoring group A very extremely seldom occurs.

A rectangular prism with a volume of 4x^3+22x^2+10x cubic units has a base area of x² +5x square units. Find the height of the rectangular prism.
The height of the prism is_____units
The height of the rectangular prism is 4x+2 unit.
What is rectangular prism?
A rectangular prism's volume is a measurement of the entire interior volume. Consider a rectangular water-filled container. In this instance, the container's capacity is equal to the maximum amount of water it can hold. A polyhedron known as a prism has the same cross-section along its entire length, equal bases, and flat rectangular side faces. Based on the design of their bases, prisms are categorised. A rectangular prism is within the category of three-dimensional shape. The prism has six faces, all of which are rectangles.
Here the given volume of rectangular prism is,
=> V= 4[tex]x^3+22x^2+10x[/tex] cubic unit
And area of base B = [tex]x^2+5x[/tex] square unit.
Now volume of rectangular prism
=> V= area of base × height
=> 4[tex]x^3+22x^2+10x[/tex] = [tex]x^2+5x[/tex] × height
=> Height = [tex]\frac{4x^3+22x^2+19x}{x^2+5x}[/tex]
=> Height = [tex]\frac{2x(2x^2+11x+5)}{x(x+5)}[/tex]
=>Height = [tex]\frac{2(2x^2+x+10x+5)}{x+5}[/tex]
=> Height = [tex]\frac{2(x(2x+1)+5(2x+1))}{x+5}[/tex]
=> Height = [tex]\frac{2(2x+1)(x+5)}{x+5}[/tex]
=>Height = 2(2x+1)
=> Height = 4x+2 unit .
Hence height of the rectangular prism is 4x+2 unit.

Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. What is the greatest number of cups of yogurt Monica can buy? Use the inequality 1.20x + 2.5 ≤ 20 to solve the problem. Monica can buy | cups of yogurt.
The greatest number of cups of yogurt that Monica can buy is 14 cups
The amount that she has = $20
The cost of one gallon of milk = $2.50
The cost of one cup of yogurt = $1.20
Consider the number of cups of yogurt = x
Then the inequality will be
1.20x + 2 .50 ≤ 20
Solve the inequality and find the value of x
Subtract 2.50 from both side of the inequality
1.20 + 2.50 - 2.50 ≤ 20 - 2.50
1.20x ≤ 17.5
Divide both side of the equation by 1.20
1.20x / 1.20 ≤ 17.5 / 1.20
x ≤ 17.5 / 1.20
x ≤ 14.58

Suppose AC = 48 cm and QD = 51 cm. What is the length of QC?
pq
QC is
cm in length.
The length of segment QC, using the Pythagorean Theorem, is of:
QC = 45 cm.
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the length of the hypotenuse is obtained according to the equation presented as follows
[tex]h^2 = l_1^2 + l_2^2[/tex]
The length of QC is obtained considering that QC is a leg of a right triangle in which:
BC is the other leg.QB is the hypotenuse.The perpendicular bisector theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the segment's endpoints, thus the length of segment QB is given as follows:
QB = QD = 51 cm.
B is the midpoint of AC, hence the length of segment BC is given as follows:
BC = 0.5 x AC = 0.5 x 48 = 24 cm.
Hence the length of QC is obtained as follows:
QC² + 24² = 51²
QC = sqrt(51² - 24²)
QC = 45 cm.

Why area of square is a2?.
By using diagonal properties of square, we can prove the area of triangle as a².
What is square?A square is a flat object in geometry that has four equal sides and four right angles (90°). An equilateral rectangle is a specific sort of square, while a parallelogram is a special kind of square (an equilateral and equiangular one).
Prove: Area of square = a²
Suppose, there is a square of side length a.
Let, d be the length of each diagonal. We know, both diagonals of square have equal length.
So, d^2 = a^2 + a^2 = 2 * (a^2)
Or, d = a * (√2).
Also, we know that diagonals of a square are perpendicular bisectors.
So, we can consider that the square as four isosceles right angled triangles.
Length of each perpendicular side of every isosceles right angled triangle = (1 / 2) * d = (d / 2).
So, area of each isosceles right angled triangle = (1 / 2) * (d / 2) * (d / 2) = {(d^2) / 8}
Area of the square = 4 * {(d^2) / 8} = {(d^2) / 2}.
Since, d = a * √2; so we put in the above formula, the area becomes equal to that of (a^2).

at a birthday party, there are 7 boys and 5 girls. what percent of the kids are boys, rounding to the nearest tenth of a percent? 41.7% 58.4% 71.4% 41.6% 58.3%
The percentage of kids who were boys in the birthday party is 58.3%.
The percentage can be calculated by the relation-
Percentage = number of boys ÷ total number of kids × 100
Calculating each value before calculating the percentage.
Number of boys = 7
Total number of kids = number of boys + number of girls
Total number of kids = 7 + 5
Performing addition
Total number of kids = 12
Keep both the values in formula -
Percentage of boys = (7÷12)×100
Percentage of boys = 58.33%
Round the number of nearest tenth, we get percentage = 58.3%
Thus, there were 58.3% boys.

The exponential function always exceeds the linear function
A mathematical function of form f (x) = an x is an exponential function. where x is a variable and an is the function's base constant The transcendental number e, which is approximately 2.71828, is the most commonly encountered exponential-function base.
An exponential function is distinguished from linear and quadratic functions in that the variable to be solved for is contained within the function's exponent rather than (necessarily) within the base of some exponential expression. Here are some examples:
Linear function: f(x) = 3x - 7: The exponents 1 and 0 are implied here, so f(x) is 3(x^1) - 7(x^0). It is worth noting that x is not a component of either exponent; rather, it is a component of the base of each exponent.
h(x) = 4^(3x + 7):This is an exponential function because the variable x is contained within the exponent in this expression.
As a result, the exponential function always outperforms the linear function.

The percentage decrease in Lora's screen time on phone is 25% this week.
Percentage related problems work around a certain reference value. This reference value is what the output percentage refers to when showing any growth or decay in the other value.
For this problem, last week's screen time is that reference value i.e. 920 minutes per week.
Now, current week's usage is 690 minutes per week. For calculating percentage decrease, we first find our the difference (in minutes).
[tex]Decrease=S_{1}- S_{2}=920-690=230[/tex]
Now, for its percentage we compare this value to our reference value i.e. last week's screen time. This will tell us about the decrease in screen time with reference to last week. This is what percentage does i.e. compares two sets of data.
