Answer:

\(\textsf{C)}\quad \dfrac{5}{16}\; \sf yd^2\)

Step-by-step explanation:

The net of a square-based pyramid is made up of:

From inspection of the given net:

The area of a square is the square of one of its side lengths.

The area of a triangle is half the product of its base and height.

The total surface area of the pyramid is the sum of the area of the square base and the area of 4 congruent triangles.

Therefore:

\(\begin{aligned}\sf Total\;surface\;area&=\sf Area_{square}+4 \cdot Area_{triangle}\\\\&=s^2+4 \cdot \dfrac{1}{2}bh\\\\&=\left(\frac{1}{4}\right)^2+4 \cdot \frac{1}{2} \cdot \frac{1}{4} \cdot \frac{1}{2}\\\\&=\dfrac{1^2}{4^2}+\dfrac{4 \cdot 1 \cdot 1 \cdot 1}{2 \cdot 4 \cdot 2}\\\\&=\dfrac{1}{16}+\dfrac{4}{16}\\\\&=\dfrac{1+4}{16}\\\\&=\dfrac{5}{16}\; \sf yd^2\end{aligned}\)

Therefore, the surface area of the pyramid is 5/16 yd².

Answer:

CE = 3

Step-by-step explanation:

Given 2 intersecting chords then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

x(x + 1) = 3 × 4 = 12

x² + x = 12 ( subtract 12 from both sides )

x² + x - 12 = 0 ← in standard form

(x + 4)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 3 = 0 ⇒ x = 3

But x > 0 so x = 3

Then

CE = x = 3

Step-by-step explanation:

The coordinate of the centroid of the given triangle will be at (-2.33,5).

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The given triangle with vertices has been drawn.

The midpoint of H( – 6, 3) and F(1, 5) will be as,

x = (-6 + 1)/2 = -2.5

y = (3 + 5)/2 = 4 so D(-2.5,4)

The coordinate of the centroid will intersect 2:1 of the median from the vertex side.

Thus by intercept formula,

x = (2 × -2.5 + 1 × -2)/(2 + 1) and y = (2 × 4 + 1 × 7)/(2 + 1)

x = -2.33 and y = 5

So the coordinate of vertices will be (-2.33,5).

Hence "The specified triangle's centroid's coordinate will be at (-2.33,5)".

According to the given information, the sample period should be from 2010-2020.

a) Model specification

The model specification based on the scenario above is as follows:

SDF= f(T, TI, NL)

Where: SDF= Sustainable Development Framework

T= Tourism

TI= Technological innovation

NL= National leadership

b) Justification for the selection of the dependent and independent variables model:

Dependent variable: The dependent variable in this model is Sustainable Development Framework (SDF). The model seeks to develop a framework for sustainable development that would facilitate growth, environmental and socio-cultural sustainability.

Independent variables:

The independent variables are tourism sustainability, technological innovation, and quality of leadership. These variables drive economic development. The inclusion of tourism sustainability reflects its importance in the global economy and its potential to drive growth.

The inclusion of technological innovation reflects its potential to enhance productivity and create new industries. The inclusion of national leadership reflects the role of governance in promoting sustainable development and managing negative externalities.

c) Justification for the selection of the sample period:

The sample period should be selected based on the availability of data for the variables of interest. Ideally, the period should be long enough to capture trends and patterns in the data. However, it should not be too long that the data becomes obsolete or no longer relevant.

Additionally, the period should also reflect the context and relevance of the research question. Therefore, the sample period for this study should cover the last decade to capture the trends and patterns in the data and reflect the relevance of the research question.

The sample period should be from 2010-2020.

answer:

sum: 19 + 7 = 26

difference: 19 - 7 = 12

step-by-step explanation:

the sum of x and y is 26. in other words, x plus y equals 26 and can be written as equation a:

x + y = 26

the difference between x and y is 12. in other words, x minus y equals 12 and can be written as equation b:

x - y = 12

now solve equation b for x to get the revised equation b:

x - y = 12

x = 12 + y

then substitute x in equation a from the revised equation b and then solve for y:

x + y = 26

12 + y + y = 26

12 + 2y = 26

2y = 14

y = 7

now we know y is 7. this means that we can substitute y for 7 in equation a and solve for x:

x + y = 26

x + 7 = 26

X = 19

good luck :)

Answer:

I believe the answer would be the option that says: "An elephant walks with a speed of 15 steps a minute. How long was the elephant walking if she walked without stopping for 480 steps?"

Answer:

C. An elephant walks with a speed of 15 steps a minute. How long was the elephant walking if she walked without stopping for 480 steps?

Step-by-step explanation:

C yields the equation of \(15x=480\), because 15 stands for steps/minute, 480 for steps, so \(x\) must stand for minutes.

For your entertainment:

A gives \(x = 480 \cdot 15\).

B gives \(x=32-15\).

D gives \(x=480+15\).

Answer:

Step 1: Simplify both sides of the equation.

4 muffins per plate (13 plates)

Other answers are possible. See below

========================================================

Explanation:

The factors of 52 are: 1, 2, 4, 13, 26, 52

If Aleesia picks any of those values, then she will divide the muffins up equally.

For example, if she puts 4 muffins per plate, then that means she'll have 13 plates since 4*13 = 52.

Or she could put 2 muffins per plate to get 26 plates (because 2*26 = 52).

To find two more multiplications with an answer of 44.206, let's use the following equation:

1) \(2.1 x 21.05 = 44.2055\)In this calculation, if we multiply

2.1 by 21.05, we get an answer of 44.2055, which is very close to 44.206. 2) \(4.020 x 11.001 = 44.22602\)By multiplying 4.020 by 11.001, we obtain a product of 44.22602, which is also close to the desired answer of 44.206. In conclusion,

we have provided two additional multiplications that have answers very close to 44.206. The first multiplication of\(2.1 x 21.05\)  yields 44.2055, while the second multiplication of esults in 44.22602.

Now, the above-mentioned hours are not in the proper form that we are required to calculate. Therefore, we need to change them into the proper format .In order to add these hours, we must first convert the hours and minutes to the same format.

We'll need to convert each fraction to a common denominator of 3x3=9.  5 4/1​ in the mixed format is 5 + 4/1,
which is equal to 9. 9 4/3 in the mixed format is 9 + 4/3,

To solve this problem, we'll use the concept of permutations.

First, we need to choose a woman for the position of president, then another woman for the position of vice president, and finally, a man for the treasurer position.

1. President: Since there are 20 women, we have 20 options for the president position.
2. Vice President: We're left with 19 women (since we already chose one for the president), so we have 19 options for the vice president position.
3. Treasurer: Since there are 17 men, we have 17 options for the treasurer position.

Now, multiply the number of options for each position together to find the total number of ways to form the committee:

20 (president) × 19 (vice president) × 17 (treasurer) = 6,460 ways.

So, there are 6,460 possible ways to choose three different members with women as president and vice president and a man as treasurer.

In this movie, the ratio of children to adults suggests that there are 27 children in attendance.

We have to give that,

There are 9 children for every 4 adults.

This means that if there were 13 people, 9 of them would be children and 4 would be adults.

Children would therefore be:

= 9 / 13

If there were 39 people, the number of children would be:
