D

Answer:

(2/3)m units

Step-by-step explanation:

The segment is m units long. After dividing it into 3 three equal parts, each part is m/3 units long. The midpoint of the first part is located at (m/3)/2 = m/6 units from the beginning of the segment. The midpoint of the last part is located at (2/3)m + m/6 = (5/6)m units from the beginning of the segment. Then, the distance between the midpoints of the first and the last parts is (5/6)m - m/6 = (2/3)m units

Line can be divided into segments.

The distance between the two midpoints is 2m/3

The length of the segment is given as:

[tex]\mathbf{Length = m}[/tex]

The length of each segment, after dividing them into 3 segments is:

[tex]\mathbf{Segment = \frac m3}[/tex]

The midpoint of the first segment is:

[tex]\mathbf{First= \frac m6}[/tex]

The midpoint of the third segment is the sum of the first two segments, and the half a segment

So, we have:

[tex]\mathbf{Third = \frac m3 + \frac m3 + \frac m6}[/tex]

[tex]\mathbf{Third = \frac{5m}{6}}[/tex]

So, the distance between the two midpoints is:

[tex]\mathbf{Distance = \frac{5m}{6} - \frac{m}{6}}[/tex]

[tex]\mathbf{Distance = \frac{5m - m}{6}}[/tex]

[tex]\mathbf{Distance = \frac{4 m}{6}}[/tex]

[tex]\mathbf{Distance = \frac{2m}{3}}[/tex]

Hence, the distance between the two midpoints is 2m/3

Answer:

The Triangle Is A Right Triangle Because 5^2 + 12^2 = 13^2.

Step-by-step explanation:

5^2 = 25. 12^2 = 144. With the Pythagorean theorem, (a^2 + b^2 = c^2), 5 is a, 12 is b, and 13 is c.

25 + 144 = 169.

13 ^ 2 = 169.

Since a^2 + b^2 = c^2 is true, the triangle is a right triangle.

Given:

Sides of triangle= 5cm, 13cm and 12cm

To find: Whether a triangle is a right angled triangle.

This can be solved by applying Pythagorean theorem:

According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

[tex]H^2=P^2+B^2[/tex]

where,

H= Hypotenuse

P= Perpendicular

B=Base

Applying given values in the formula:

[tex]H^2=P^2+B^2\\\\13^2=5^2+12^2\\\\169=25+144\\\\169=169[/tex]

Since, R.H.S= L.H.S

Thus, we can say that this triangle is a right angled triangle.

Step -by -step verification:

Total number of female students that play instruments

Total number of students =43/140

If a musician is selected at random, the probability that the individual is a female student is; 15/28

We are given;

Total Number of High school students surveyed = 140

Number of males that play instruments = 24

Number of males that don't play instruments = 41

Number of females that play instruments = 43

Number of females that don't play instruments = 32

Thus, If a musician is selected at random, the probability that the individual is a female student is;

P(Female Student) = (43 + 32)/140 = 75/140 = 15/28

Answer:

x = -1

Step-by-step explanation:

Write it in exponential form, 2^3 = 2^x+4

Since base is the same, Set the exponents equal, 3 = x + 4

Move the terms, variable goes to the left side and change the sign -x + 3 = 4

Subtract and calculate, -x = 1

Change the signs on both sides, x = -1

Step-by-step explanation:

Answer:

The Volume is 2,200

Step-by-step explanation:

10+8.8= 18.8

13.7+25= 38.7

18.8+38.7= 57.5

This is the incorrect way

__________________________________________________

Correct way:

Volume= L×H×W

25 × 8.8 × 10 =  2,200

The total volume of the figure is 693 m³.

Volume of a three dimensional shape is the space occupied by the shape.

Given a composite figure consisting of a triangular pyramid and a triangular prism.

Total volume of the figure = Volume of pyramid + volume of prism

Volume of the pyramid = 1/3 × base area × height

Base area = 1/2 × √(13.7² - 8.8²) × 8.8

                 = 1/2 × 10.5 × 8.8

                 = 46.2 m²

Volume of the pyramid = 1/3 × 46.2 × (25 - 10)

                                       = 231 m³

Volume of the prism = base area × height

                                  = 46.2 × 10

                                  = 462 m³

Total volume = 231 m³ + 462 m³ = 693 m³

Hence the total volume is 693 m³.

Answer:

Adult tickets cost $11 and child tickets cost $13

Step-by-step explanation:

Multiply the second equation by -2, then add the equations together.

(8a+9c=205)

−2(4a+3c=83)

Becomes:

8a+9c=205

−8a−6c=−166

Add these equations to eliminate a:

3c = 39

Then solve3c=39for c:

3c=39

[tex]\frac{3c}{3}[/tex] = [tex]\frac{39}{3}[/tex]

(Divide both sides by 3)

c = 13

Now that we've found c let's plug it back in to solve for a.

Write down an original equation:

8a+9c=205

Substitute 13 for c in 8a+9c=205:

8a+(9)(13)=205

8a+117=205 (Simplify both sides of the equation)

8a+117+−117=205+−117 (Add -117 to both sides)

8a=88

[tex]\frac{8a}{8}[/tex] = [tex]\frac{88}{8}[/tex]

(Divide both sides by 8)

a = 11
