Answer:

decrease by 50%

Step-by-step explanation:

[tex]\frac{0.4x}{0.8y} =\frac{x}{2y}[/tex]      

Decreased by 60% = (100%-60%)x = 0.4x.

Decreased by 20% = (100%-20%)x = 0.8x.

[tex]\frac{x}{y}[/tex] initial fraction, and we can see that denominator will increase 2 times, so fraction will decrease 2 times, or decrease by 50%.

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

Answer:

Then a is the real part and b the imaginary part

Given

z = - 91 + 14.6i , then

- 91 is the real part and 14.6 the imaginary part

Step-by-step explanation:

You will have to use pythagorean theorem

Answer:

A cup chocolate chips weighs about 9 ounces.

=> 3 cups of chocolate chips weigh about 9 x 3 = 27 ounces.

=> 3/4 cup of chocolate chips weigh about 9 x 3/4 = 27/4 = 6.75 ounces.

=> 3 and 3/4 cups of chocolate chips weigh about 27 + 6.75 = 33.75 ounces.

Answer:

Hello There the Correct answer is 20% start off by finding 10% of $14. in order to find 10%, divide it by 70 which gives 2. you now need to make the 30% to add to the 70%, by timesing the 2 by 3to give 6. now all you need to do it add the 6 to 14 to make 20!

so your answer is $20

Hope it helps!

Answer:

Joe paid 14.00 for a board game.

This is 70% of the original price X (70/100 of original price).

We have the ratio: 14/X = 70/100

=> The original price: X = 14 x 100/70 = 20

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

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:

10 < x <22

Step-by-step explanation:

The smallest side must be larger than the difference of the two sides

16-6 = 10

x>10

The largest side must be smaller then the sum of the two sides

6+16 =22

x< 22

Put this together

10 < x <22

Answer:

10 < c < 22

Step-by-step explanation:

Remember the Triangle Inequality Theorem.

For a triangle with sides a, b, and c:

- a + b > c

- a + c > b

- b + c > a

Let's arbitrarily say a = 6 and b = 16. Then:

a + b > c

6 + 16 > c

c < 22

a + c > b

6 + c > 16

c > 10

b + c > a

16 + c > 6

c > -10

Thus, the range of possible lengths of the third side, c, is 10 < c < 22.

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.
