Reese read twice as many pages Saturday than she read Sunday. If she read a total of 78 pages over the weekend, how many pages did Reese read Sunday?

Answers

Answer 1

Answer:

Answer:

Reese read 26 pages on Sunday.

Step-by-step explanation:

If she read twice the amount on Saturday than she read on Sunday, then you can replace the days with variables. 2x for Saturday and x for Sunday. That leaves you with 2x + x = 78. This can be simplified to 3x = 78. We can solve this by dividing both sides by 3. This leaves you with x = 26. If x represents the pages read on Sunday then Reese read 26 pages on Sunday.

Count the number of 1 bits after the last decimal point. Call this number n.

There will be 2^n subnets and 2^(8-n) - 2 hosts per subnet. (You can mutilply the number of subnets by the number of hosts per subnet to find the total number of hosts.)

/25: 255.255.255.128, 2 subnets, 126 hosts per subnet

/26: 255.255.255.192, 4 subnets, 62 hosts per subnet

/27: 255.255.255.224, 8 subnets, 30 hosts per subnet

/28: 255.255.255.240, 16 subnets, 14 hosts per subnet

/29: 255.255.255.248, 32 subnets, 6 hosts per subnet

Final answer:

This answer explains subnet mask equivalents and calculates the number of subnets and hosts for different subnet mask values.

Solve the differential equation x^2 y"-xy' +y 0

Answers

Answer:

$y(x)\ =\ √(x)[C_1cos(√(3))/(2)logx+C_2sin(√(3))/(2)logx]$

Step-by-step explanation:

Given differential equation is

$x^2y$ (1)

Let's assume that

$x=e^t$

$=>\ t\ =\ logx$

then,

$(dx)/(dt)=e^t$

$and\ (d^2x)/(dt^2)=e^t$

We can write,

$(dy)/(dx)=(dy)/(dt).(dt)/(dx)$

$=e^(-t)(dy)/(dt)$

Similarly,

$(d^2y)/(dt^2)=(d^2y)/(dt^2).(dt^2)/(dx^2)$

$=e^(-2t).(d^2y)/(dt^2)$

Putting these values in equation (1), we will get

$e^(2t).e^(-2t).(d^y)/(dt^2)-e^t.e^(-t)(dy)/(dt)+y=0$

$=>(d^2y)/(dt^2)-(dy)/(dt)+y=0$

So, the characteristics equation can be given as

$D^2-D+1=0$

$=>D\ =\ (1+√(1-4))/(2)\ or\ (1-1√(1-4))/(2)$

$=>D=\ (1)/(2)+i(√(3))/(2)\ or\ (1)/(2)-i(√(3))/(2)$

Hence, the general solution of the equation can be give by

$y(t)\ =\ e^{(t)/(2)}[C_1cos(√(3))/(2)t+C_2sin(√(3))/(2)t]$

Now, by putting the value of t in above solution, we will have

$y(x)\ =\ e^{(1)/(2)logx}[C_1cos(√(3))/(2)logx+C_2sin(√(3))/(2)logx]$

$y(x)=\ √(x)[C_1cos(√(3))/(2)logx+C_2sin(√(3))/(2)logx]$

Hence, the solution of above given differential equation can be given by

$y(x)=\ √(x)[C_1cos(√(3))/(2)logx+C_2sin(√(3))/(2)logx]$

Perform the indicated operations. Write answer in descending order.Add -3x, 5x + y, and 7x - 8 - 3y

Answers

The required sum of -3x, 5x + y, and 7x - 8 - 3y in descending order is 9x - 2y - 8.

What is simplification?

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

Here,
To add -3x, 5x + y, and 7x - 8 - 3y, we can first combine like terms.

Group the x-terms together:

-3x + 5x + 7x = 9x

Group the y-terms together:

y - 3y = -2y

Group the constants together:

-8

Putting it all together, we get:

9x - 2y - 8

Therefore, the sum of -3x, 5x + y, and 7x - 8 - 3y in descending order is 9x - 2y - 8.

Tell whether the following set is an empty set or not. A = {A quadrilateral having 3 obtuse angles}

Answers

Answer:

It is not an empty set

Step-by-step explanation:

Obtuse angles are angles greater than 90 and less than 180.

There are quadrilaterals having 3 obtuse angles and they are possible.

If we imagine 3 obtuse angles of 91 degrees (obtuse angle), the 4th angle will be

360-91-91-91

=> 87 degrees

So, This quadrilateral can be constructed!

And also with 92, 93, 94 and so on!

So, Set A is not an empty set!

Answer:

It is not an empty set

Step-by-step explanation:

A quadrilateral with 3 obtuse angles is possible.

A obtuse angle has a measure of more than 90 degrees and less than 180 degrees.

Let’s say three angles are measuring 91 degrees in a quadrilateral.

91 + 91 + 91 + x = 360

x = 87

The measure of the fourth angle is 87 degrees which is less than 360 degrees and is a positive integer, so it is possible.

Answer:

27 degrees

Step-by-step explanation:

1= 63 degrees

Using alternating angles, acute angle made at T is 63 degrees.

Angles in a triangle add upto 180, thus, 90+ 63= 153

180-153 = 27
