How to multiply 2*3*5*7 (I need explanation)

Area of semicircle is 77.

What is semicircle?

A semicircle is defined as half circle formed by cutting the circle into two halves.

Given that;

Diameter of semicircle = 14

Radius of semicircle = 14/2 = 7

Now, Area of semicircle = 1/2 (πr²)

Substitute π = 22/7 and r = 7, we get;

Area of semicircle = 1/2 (πr²)

                             = 1/2 × (22/7) × 7 × 7

                             = 77

So, Area of semicircle is 77.

The area of the rectangular arena can be represented as A = (8y2 - 18y) square feet.

Here, we are given the dimensions of a rectangular arena, which are as follows-

Length = 4y - 9 feet

width = 2y feet

The area of a rectangle is given by the formula-

Area of a rectangle = length x breadth

Thus, in this case, area (A) can be calculated as follows

A = (4y - 9) * 2y

Now, we simplify the equation-

A = (4y)(2y) - 9(2y)

A = 8 - 18y

Thus, the area of the rectangular arena can be represented by the following equation- A = (8 - 18y) square feet.

Step-by-step explanation:

The easiest way of calculating discount is, in this case, to multiply the normal price $80 by 40 then divide it by one hundred. So, the discount is equal to $32. To calculate the sales price, simply deduct the discount of $32 from the original price $80 then get $48 as the sales price.

[tex]\sqrt{161}[/tex] ft

Step-by-step explanation:

According to the pythagorean theorem, in a right-angle triangle, the sum of of the squared legs is equal to the hypotenuse squared.

In simpler words, if we have legs [tex]a[/tex] and [tex]b[/tex], as well as hypotenuse [tex]c[/tex], then [tex]a^2 + b^2 = c^2[/tex].

In our case, we know that [tex]a = 8[/tex] and [tex]c = 15[/tex], therefore, we should try and find b.

[tex]8^2 + b^2 = 15^2\\\to 64 + b^2 = 225 \text{ // Subtract by 64}\\\to b^2 = 161 \text{ // Take the square root of both sides}\\\to b = \sqrt{161}[/tex]

The value of the angle  x is 108 degree.

According to the statement

We have to find that the value of the x in the adjacent angle.

So, For this purpose, we know that the

The adjacent angles is the two angles are said to be adjacent angles when they share the common vertex and side.

From the given information:

When we extend line AB to E

Then ∠EBC is created

Since BC is parallel to AD

So, ∠EBC =∠BAD = x° (corresponding angles are equal )

Linear pair : Two angles are said to be linear if they're adjacent angles formed by two intersecting lines. The measure of a angular unit is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Now With the linear pair property

x+(x-36) = 180

2x - 36 = 180

2x  = 180+36

2x = 216

x = 216/2

x = 108.

Then one angle is of 108 degree and second angle is 72 degree.

So, The value of the angle  x is 108 degree.

Expand the limand as

[tex]\dfrac{e^{x^3} - (1 - x^3)^{1/3} + \left((1-x^2)^{1/2} - 1\right) \sin(x)}{x \sin^2(x)} \\\\ ~~~~~~~~ = \dfrac{e^{x^3} - (1-x^3)^{1/3}}{x^3} \cdot \dfrac{x^2}{\sin^2(x)} + \dfrac{(1-x^2)^{1/2} - 1}{x^2} \cdot \dfrac{x}{\sin(x)}[/tex]

Recall that for [tex]a\neq0[/tex],

[tex]\displaystyle \lim_{x\to0} \frac{\sin(ax)}{ax} = 1[/tex]

Then

[tex]\displaystyle \beta = \lim_{x\to0} \left( \dfrac{e^{x^3} - (1-x^3)^{1/3}}{x^3} + \dfrac{(1-x^2)^{1/2} - 1}{x^2}\right)[/tex]

Rationalize the numerators.

[tex]\dfrac{e^{x^3} - (1-x^3)^{1/3}}{x^3} = \dfrac{e^{3x^3} - (1 - x^3)}{x^3 \left(e^{2x^3} + e^{x^3} (1-x^3)^{1/3} + (1-x^3)^{2/3}\right)} \\\\ ~~~~~~~~~~~ = \left(\dfrac{e^{3x^3} - 1}{x^3} + 1\right) \cdot\dfrac1{e^{2x^3} + e^{x^3} (1-x^3)^{1/3} + (1-x^3)^{2/3}}[/tex]

and observe that

[tex]\dfrac1{e^{2x^3} + e^{x^3} (1-x^3)^{1/3} + (1-x^3)^{2/3}} \to \dfrac13[/tex]

[tex]\dfrac{(1-x^2)^{1/2}-1}{x^2} = \dfrac{(1-x^2) - 1}{x^2 \left((1-x^2)^{1/2} + 1\right)} \\\\ ~~~~~~~~ = -\dfrac1{(1-x^2)^{1/2} + 1} \to -\dfrac12[/tex]

This leaves us with

[tex]\displaystyle \beta = \lim_{x\to0} \frac{e^{3x^3} - 1}{3x^3} - \frac16[/tex]

The remaining limit is the derivative of [tex]e^{3x^3}[/tex] at [tex]x=0[/tex], so its value is 1, and we find

[tex]\beta = 1 - \dfrac16 = \dfrac56 \implies 6\beta = \boxed{5}[/tex]

Let x be the shortest side

Let x+1 be the second side

The estimated number of students at the M College who agree climate change is a serious issue is  1759

The percentage of total students is 59.42%

The method used can be biased.

The students surveyed are the sample while the students in the M College are the population. A population is the party of interest in an experiment. A population consists of all the members of the group. A sample is a smaller group of the population.

The limitation of using a sample to estimate for the population is that the sample might be a biased estimate of the population. If the sample is biased, the result of the experiment would be inaccurate.

Estimated number of students at M College = (sample that agree that climate change is a serious problem / total number of people surveyed) x number of students

(205 / 345) x 2960 = 1759

Percentage = (1759 / 2960) x 100 = 59.42%

Step-by-step explanation:

The midpoint of the segment where the segment has the  endpoints (-8,-7) and (-7,-8)  is (-15/2, -15/2)

On the segment, we have the following endpoints

(-8,-7) and (-7,-8)

The midpoint of the segment is calculated using

Midpoint = 1/2 * (x1 + x2, y1 + y2)

Where

(x1, y1) = (-8,-7)

(x2, y2) = (-7,-8)

Substitute the known values in the above equation

So, we have

Midpoint = 1/2 * (-8 + -7, -7 - 8)

Evaluate the difference in the above equation

So, we have

Midpoint = 1/2 * (-15, -15)

Evaluate the product in the above equation

So, we have

Midpoint =  (-15/2, -15/2)

Hence, the midpoint of the segment where the segment has the  endpoints (-8,-7) and (-7,-8)  is (-15/2, -15/2)

4. The two triangles are similar by virtue of the AAA triangle congruence theorem as a result of the corresponding angles which have equal measures.

5. The length of segment CE to the nearest tenth is; 46.7 in.

4. The ∆CBD and ∆CAE are similar (congruent) following the fact that angle C is common to both triangles and the angles A and E have equal measures as E and D respectively by virtue of corresponding angles theorem. Ultimately, the two triangles; ∆CBD and ∆CAE are congruent since all three angle measures are the same in the triangles.

The corresponding angles in discuss is due to the fact that the lines ED and AE are parallel lines.

5. Also, upon establishing the congruence of the two triangles, it follows that the ratio of their corresponding sides is same for all three sides.

Therefore, we can establish that;

BD/AE = CD/CE

6/14 = 20/CE

CE = (14 × 20)/6

The value of x is 10.

Given m∠3 = 4x+10 and m∠4 = 5x

Now, we need to determine what value of x it is.

We know that in quadrilateral four angles are there in that two angles are equal it is said to be as Rhombus.

Two angles are given in this question. We assume those are equal angles.

∴ m∠3 = m∠4

By substituting the values of two angles, we get

4x+10 = 5x

By deducting '4x' on both sides, we get

4x+10-4x = 5x - 4x

10 = x

Using ratio, we concluded that there are total 144 people at the basketball game.

Ratios contrast two figures by typically dividing them. A/B would be your formula if you were comparing one data point (A) to another data point (B). This indicates that you are multiplying information A by information B. For instance, your ratio will be 5/10 if A is 5 and B is 10.

Let x be the number of people at the basketball game.

4x = number of males

5x = number of females

Total females = 80

⇒ 5x = 80

⇒ x = 16

4x = 4 × 16

⇒ 64

∴ Total males  = 64

Total people present = number of males + number of females
