An earring design is shaped like a triangular pyramid. All the faces are equilateral triangles with side lengths of 14 millimeters. The slant height is 12.1 millimeters. What is the surface area of the earring (pls explain how u got the answer)

In the earring design described above, there are 4 equilateral triangles. The surface area is calculated by solving for the area of a single triangle and multiplying the answer by 4. The area of an equilateral triangle is calculated by the equation,
                                   A = ((√3)/4)s²
Substituting 14 to s and multiplying the answer by 4
                                 SA = √3 x (14 mm)² = 339.48 mm²
Thus, the surface area of the earring is approximately 339.48 mm².

The two triangles below are similar. Find the value of x. Be sure to explain your steps

Answer:

x=8

Step-by-step explanation:

Given two triangles are similar

When two triangles are similar , then the length of two similar triangles are always  proportional.

The length of the corresponding sides are proportional

Ratio of hypotenuse = Ratio of the base

\frac{20}{10} = \frac{x}{4}

Now we solve for x

Cross multiply the fractions

4 * 20 = x* 10

80 = 10x

Divide by 10 on both sides

x= 8

WORTH 10 POINTS! Mara decides to plot her neighborhood on a coordinate plane. She plots her house at the point (0,0), her school is located at (0,8), the library at (3,8), and the softball field is at (3,0). One day she decides that after school she will run by the library to grab a book, and then head to softball practice and then back home. How far on the coordinate plane does she travel starting at home that morning? Leave your answer in units. A) 11 units B) 14 units C) 19 units D) 22 units

Answer:

Option: D is the correct answer.

D) 22 units.

Step-by-step explanation:

Her home is located at: (0,0)

School at (8,0)

Library at (3,8)

and softball field is located at (3,0) on the coordinate plane.

Now, that morning she starts from home then goes to school then after school she goes to Library and then after library she goes to softball field and returns back home.

Home→ school → Library → Softball field → Home.

This means that she covers the boundary of the rectangle that is formed by the location of the points.

This means in order to find the total distance she traveled we need to find the perimeter of the rectangle.

Length of One side of rectangle(a)= 8 units.

Length of the other side of rectangle(b) = 3 units.

Hence,

Perimeter of rectangle= 2(a+b)

                                    = 2(8+3)

                                   =2×11

                                   = 22 units.

Hence, the total distance she traveled is:

                       22 units.

The base of a triangle is twice its hypotenuse, the sine of the angle opposite to its base is a) Ö3/2, b) 1, c) 1/2, d) Ö3

Answer:

Option (c) is correct .

The base of a triangle is twice its hypotenuse, the sine of the angle opposite to its base is =\frac{1}{2}

Step-by-step explanation:

Given : base =  twice its hypotenuse

that is ,

Consider hypotenuse  be x  then base will be 2x .

Consider the right angled triangle in figure below with right angle at B and base BC.

∠A is the angle opposite to the base.

\text sinA=\frac{\text Perpendicular}{\text Hypotenuse}

\text sinA=\frac{BC}{AC}

\text sinA=\frac{x}{2x}

\text sinA=\frac{1}{2}

Thus, For the base of a triangle is twice its hypotenuse, the sine of the angle opposite to its base is =\frac{1}{2}

Matt is making cookies. He adds 3 over 4 cup of sugar to a bowl. He then removes two 1 over 8 cups of sugar. Which of the following best explains the amount of sugar left in the bowl? A 4/8 because 3/4-2*(1/8)=3/4-3/8. B 4/8 because 3/4-2*(1/8)=3/4-2/8

Answer:

 Option B) is the correct answer.        

Step-by-step explanation:

We are given the following information in the question.

Amount of sugar added to bowl = \displaystyle\frac{3}{4}

Amount of sugar removed = 2\times \displaystyle\frac{1}{8}

In order to calculate total amount of sugar = \text{Amount of sugar added in the bowl} - \text{Amount of sugar removed from the bowl}

= \displaystyle\frac{3}{4} - (2\times \displaystyle\frac{1}{8} ) \\\\= \displaystyle\frac{3}{4} - \displaystyle\frac{2}{8}\\\\= \displaystyle\frac{6}{8} - \displaystyle\frac{2}{8}\\\\= \displaystyle\frac{4}{8}

Thus, Option B) is the right interpretation.

Which of the following similarity statements about the triangles in the figure are true?

Answer: ΔPQS ≈ ΔPQR ≈ ΔPQS    

Step-by-step explanation:

In the given picture we have a right triangle PQR inw hich SQ is perpendicular  to PR.

Then ΔPQS and ΔQRS are also right triangle.

Now, in ΔPQS and ΔPQR

∠PSQ=∠PQR [right angle]

∠P=∠P [common]

∴ΔPQS ≈ ΔPQR        [BY AA similarity ]                          → (1)

In ΔPQR and ΔPQR

∠RSQ=∠PQR [right angle]

∠R=∠R [common]

∴ΔPQR ≈ ΔPQR      [BY AA similarity ]                          → (2)

From (1) and (2), we have

    ΔPQS ≈ ΔPQR ≈ ΔPQS    

Because if two triangles is similar to one triangle then all three triangles are similar to each other  [BY AA similarity ]          .

Use two rectangles of equal width to estimate the area between the graph of f(x) = x + cos(πx) and the x-axis on the interval [2, 6]. Evaluate the function at the mid-point of each rectangle to find each height. (2 points) 16 3 12 6

We find the base of the rectangles by taking the difference between the interval endpoints, and dividing by 2.
Base of rectangle = (6 - 2) / 2
= 2

The area of the first rectangle:

(4 - 2)f(4) = 2[4 + cos(4π)]


The area the second triangle:

(6 - 4)f(6) = 2[6 + cos(6π)]


Now just compute the two areas and combined them. That will give you the estimated under the curve.


To evaluate the midpoint of each rectangle, we take the midpoint of the base lengths of each rectangle. This midpoint is the x value. Then evaluate the function at that x value.


The midpoint of the first rectangle is x=3. Evaluate f(3).
The midpoint of the second rectangle is x=5. Evaluate f(5).

Triangle TRI has a base of m centimeters and a height of n centimeters. Rectangle RECT has a length of n centimeters and a width of m centimeters. Use complete sentences to compare the areas of triangle TRI and rectangle RECT.

Answer:

\text{Area of triangle}=\frac{1}{2}\text{Area of rectangle}

Step-by-step explanation:

In triangle TRI

Height of triangle = n

Base of triangle = m

Formula of area of triangle = \frac{1}{2} \times Base \times Height

Area of ΔTRI = \frac{1}{2} \times m \times n

In rectangle RECT

Length = n

Width = m

Formula of area of rectangle = Length \times Width

Area of rectangle RECT= m\times n

On comparing Area of triangle and rectangle.

We can conclude that area of triangle is half of the area of rectangle .

\text{Area of triangle}=\frac{1}{2}\text{Area of rectangle}
