For given 30 60 90 triangle, the values of the hypotenuse = 4 units and short side = 2 units

We know that, a 30 60 90 triangle is right triangle.

In right triangle the longest side is hypotenuse.

Here, hypotenuse = 4 units

The short side of triangle is the opposite to the side of smallest angle.

So, we need to find the length of the side opposite to angle 30.

Consider sin(30) = short side/hypotenuse

1/2 = short side/4

short side = 4/2

short side = 2 units

Therefore, for given 30 60 90 triangle, the values of the hypotenuse = 4 units and short side = 2 units

Answer:

[tex] a^\frac{5}{2} = \sqrt{a^5} = (\sqrt {a})^5 [/tex]

Step-by-step explanation:

A number raised to a fraction as an exponent means the number is raised to the numerator of the exponent, and then take the root shown by the denominator of the exponent.

For example, if the exponent is 2/3, raise the number to the 2nd power and take the third root.

Here is the definition:

[tex]a^{\frac{m}{n}} = \sqrt[n]{a^m} = (\sqrt[n]{a})^m[/tex]

[tex] a^\frac{5}{2} = \sqrt{a^5} = (\sqrt {a})^5 [/tex]

The length of segment QC, using the Pythagorean Theorem, is of:

QC = 45 cm.

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:

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.

The total amount Bridget received from her mom will be $6 as she will get extra for cleaning before 6PM.

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

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.

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.

Answer:25

Step-by-step explanation:

The rate of change from 2015 to 2017 is -$250

The amount he spend for lunch in 2015 = $800

The amount he spend for lunch in 2017 = $300

Therefore the total change = The amount he spend for lunch in 2017 - The amount he spend for lunch in 2015

Substitute the values in the equation

= 300 - 800

= -500

The total years from 2015 to 2017 = 2 years

The rate of change from 2015 to 2017 = The total change / The total years from 2015 to 2017

= -500 / 2

= -$250

Hence, the rate of change from 2015 to 2017 is -$250

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.

By using diagonal properties of square, we can prove the area of triangle as a².

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).

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°

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
