5 litres - 9 cups = 6 pints

⇒ Equation 2

Relationship between cups and

Rearranging equation 1 to make pints the subject

⇒ substitute this into Equation 2

Hence, 1 litre = 2.1 cups

Relationship between cups and pints

Rearrange equation 1 to make litres the subject

⇒ Substituting this into Equation 2

Hence, 1 pint = 2 cups

Relationship between pints and liter

Rearranging equation 1 to make cup the subject

⇒ subsitute this into equation 2

alexgriva [62]

Answer:

Please see the answer below

Step-by-step explanation:

a. Since there’s no restrictions .Therefore , the number of ways = 7!*150 = 756000

b. The number of ways such that the 4 math books remain together

The pattern is as follows:  MMMMEEE, EMMMMEE, EEMMMME, and EEEMMMM

Where M = Math’s Book and E= English Book.  

Number of ways = 4!*8!*4*150= 86400 ways.

c. The number of ways such that  math book is at the beginning of the shelf

The number of ways = 6!*4*150 = 432000

d. The number of ways such that  math and English books alternate

The number of ways = 150*4!*3! =2160 ways

e.  The number of ways such that math is at the beginning and an English book is in the middle of the shelf. The number of ways = 4*3*5!*150 =216000 ways.

astra-53 [7]

Answer:

A) A and B are supplementary

Step-by-step explanation:

we know that

For any inscribed  quadrilateral in the circle , opposite angles will be supplementary

so

In this problem

Angle A and Angle B are supplementary angles

m\angle A+m\angle C=180^o

Angle B and Angle D are supplementary angles

m\angle B+m\angle D=180^o

therefore

<u><em>The sentences that are true </em></u>

A) A and B are supplementary
