the values of w is inversely proportional to m .if w=8 then m=25; what is m when w=20?

Answers

Answer 1

Answer:

m = 10

Step-by-step explanation:

Given w is inversely proportional to m then the equation relating them is

w = [tex]\frac{k}{m}[/tex] ← k is the constant of variation

To find k use the condition w = 8, m = 25 , then

8 = [tex]\frac{k}{25}[/tex] ( multiply both sides by 25 )

200 = k

w = [tex]\frac{200}{m}[/tex] ← equation of variation

When w = 20 , then

20 = [tex]\frac{200}{m}[/tex] ( multiply both sides by m )

20m = 200 ( divide both sides by 20 )

m = 10

which of the following is the solution to the equation 25(z-2 )= 125?

A. z= 5.5
B. z = 3.5
D. z = -2.5
E. z = -0.5

Answers

Answer:

The answer is z = 7.

Step-by-step explanation:

1) Divide both sides by 25.

[tex]z - 2 = \frac{125}{25} [/tex]

2) Simplify 125/25 to 5.

[tex]z - 2 = 5[/tex]

3) Add 2 to both sides.

[tex]z = 5 + 2[/tex]

4) Simplify 5 + 2 to 7.

[tex]z = 7[/tex]

Thus, the answer is z = 7.

The cargo hold of a truck is a rectangular prism measuring 18 feet by 13.5 feet by 9 feet. The driver needs to figure out how many storage boxes he can load. Choose true or False for each statement.

Answers

Answer:

B

Step-by-step explanation:

The solution is

Option A - True

The volume of the rectangular cargo is 2187 feet³

Option B - True

The volume of the rectangular cargo is 2187 feet³

Option C - True

The volume of the rectangular cargo is 2187 feet³

Option D - True

The volume of the rectangular cargo is 2187 feet³

What is the Volume of a Rectangle?

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the cargo hold be a rectangular prism

Now , the dimensions of the rectangular prism is

18 feet x 13.5 feet x 9 feet

And , the Volume of Rectangle = Length x Width x Height

Substituting the values in the equation , we get

Volume of Rectangle = 18 x 13.5 x 9

Volume of Rectangle = 2187 feet³

a)

The number of boxes = 6

The dimensions of the cargo be = 9 feet x 4.5 feet x 9 feet

So , the volume of the cargo = number of boxes x 9 x 4.5 x 9

On simplifying the equation , we get

Volume of the cargo = 6 x 364.5

Volume of the cargo = 2187 feet³

b)

The number of boxes = 81

The dimensions of the cargo be = 3 feet x 3 feet x 3 feet

So , the volume of the cargo = number of boxes x 3 x 3 x 3

On simplifying the equation , we get

Volume of the cargo = 81 x 27

Volume of the cargo = 2187 feet³

c)

The number of boxes = 24

The dimensions of the cargo be = 4.5 feet x 4.5 feet x 4.5 feet

So , the volume of the cargo = number of boxes x 4.5 x 4.5 x 4.5

On simplifying the equation , we get

Volume of the cargo = 24 x 91.125

Volume of the cargo = 2187 feet³

d)

The number of boxes = 12

The dimensions of the cargo be = 9 feet x 4.5 feet x 4.5 feet

So , the volume of the cargo = number of boxes x 9 x 4.5 x 4.5

On simplifying the equation , we get

Volume of the cargo = 12 x 182.25

Volume of the cargo = 2187 feet³

Hence , the volume of the rectangular cargo is 2187 feet³

6. P(rolling an even number, spinning a vowel) _________

7. P(rolling a number less than 3, spinning a consonant)

Answers

Answer:

5)  P(2 AND A) = 1/6 x 1/8 = 1/48

6)  P(even AND vowel) = 1/2 x 2/8 = 1/8

7)  P(LT 3 AND not vowel) = 2/6 x 6/8 = 1/4

Step-by-step explanation:

1. P( 2, spinning an A) = 1/48

2. P( even number, spinning a vowel) = 1/8

3. P( number less than 3, spinning a consonant) = 1/4

What is probability?

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes. Statistics is the study of occurrences that follow a probability distribution.

Given:

Combining the spinning of an A-H spinner with the rolling of a number cube

1. P(rolling a 2, spinning an A)

= 1/6 x 1/8

= 1/48

2. P(rolling an even number, spinning a vowel)

= 1/2 x 2/8

= 1/8
