Mark and Allen were assigned the same book to read for class. Mark started reading on Saturday , and he is reading 40 pages per day. Allen didn't start until Sunday , but he is still reading 45 pages a day.

How many days will it take Allen to catch up to Mark, and how many pages will they each have read?

Let x represent the number of days Allen has been reading.

Answers

Given:

Mark started reading on Saturday , and he is reading 40 pages per day.

Allen didn't start until Sunday , but he is still reading 45 pages a day.

To find:

How many days will it take Allen to catch up to Mark, and how many pages will they each have read?

Solution:

Let [tex]x[/tex] represent the number of days Allen has been reading. Then the number of days Mark has been reading is [tex](x+1)[/tex].

Mark is reading 40 pages per day. So, he will read [tex]40(x+1)[/tex] pages.

Allen is reading 45 pages a day. So, he will read [tex]45x[/tex] pages.

Allen catch up to Mark when they read equal number of pages.

[tex]40(x+1)=45x[/tex]

[tex]40x+40=45x[/tex]

[tex]40=45x-40x[/tex]

[tex]40=5x[/tex]

Divide both sides by 5.

[tex]\dfrac{40}{5}=\dfrac{5x}{5}[/tex]

[tex]8=x[/tex]

In 8 days Allen will catch up to Mark.

[tex]45x=45(8)[/tex]

[tex]45x=360[/tex]

Therefore, they each have read 360 pages.

Answers

Answer:

Step-by-step explanation:

For this, we kind of have to test points to solve it. First, we can test theh interval x<= -2. Plug in  -2 and we get a negative value which works. Next, let's try -2<x<0. Plug in -1 and get a positive value which doesn't work.

Next try 0<=x<=7. Plug in any number like 4 and get a negative value which works.

Finally, try x>7. Plug in 8 for example and you would get a positive value. So the solution is

x <= -2 OR 0 <= x <= 7

Age math……….. help!!!!!!

Answers

Let k be Kaden's current age and s Sally's current age.

Right now, Kaden is 18 years older than Sally, so

k = s + 18

In 5 years, Kaden will be 3 times older than Sally, so that

k + 5 = 3 (s + 5)

Substitute the first equation into the second one to solve for s :

(s + 18) + 5 = 3 (s + 5)

s + 18 + 5 = 3s + 15

s + 23 = 3s + 15

3s - s = 23 - 15

2s = 8

s = 4

Answers

Answer:

Total time taken by train = 8 hour 32 minutes

Step-by-step explanation:

Given:

Time train leave Zurich = 22:40 min

Time train arrives in Vienna = 07:32

Find:

Total time taken by train

Computation:

Total time taken by train = [23:60 - 22:40] + 7:32

Total time taken by train = 1:20 + 7:32

Total time taken by train = 8:52

Total time taken by train = 8 hour 32 minutes

What is 20% of 10% of 1000

Answers

Answer:

20% of 10% of 1000 = 20

Step-by-step explanation:

Now we have to,

→ find the 20% of 10% of 1000.

Let's find 10% of 1000,

→ (10/100) × 1000

→ 0.1 × 1000

→ 100

Then 20% of 10% of 1000 is,

→ (20/100) × 100

→ 0.2 × 100

→ 20

Hence, the answer is 20.

The solution is 158,5

Step-by-step explanation:

52-6×1+75×3÷2

How would you describe the difference between the graphs of f(x) = x^2 +4 and
g(y) - y^2 +4?

Answers

Answer:

Step-by-step explanation:

The function [tex]f(x)=x^2+4[/tex] is a positive upwards opening parabola with the vertex at (0, 4), whereas

the function [tex]g(y)=y^2+4[/tex] is a positive rightwards opening parabola (sideways parabola) with the vertex at (4, 0). This means that answer to this is that g(y) is reflected over the x axis whereas f(x) is reflected over the y axis.

In 1993 eggs cost $0.87 a dozen. In 2003 it cost $1.56 a dozen. How much did the eggs appreciate (percent of increase)?

Show your work.​

Answers

Answer:

190%

Step-by-step explanation:

$1.56 is close to nearly 2x the value of $0.87

You can start by multiplying $0.87 by 2 to get $1.74

Now put $1.56 / $1.74

This gets you 0.89655172

By rounding this, you can get to 0.90

Move the decimal places two spots over to get a percentage = 90%

Since the eggs didn't decrease in value, you can add the 100% from the beginning of the problem.

100+90=190%

The expression is:

[tex]\left(\dfrac{1}{7}-4\sqrt{3}\right)^3+\left(\dfrac{1}{7}+4\sqrt{3}\right)^3 [/tex]

To find:

The simplified form of the given expression.

Solution:

Formulae used:

[tex](a-b)^3=a^3-3a^2b+3ab^2-b^3[/tex]

[tex](a-b)^3=a^3+3a^2b+3ab^2+b^3[/tex]

Adding this formulae, we get

[tex](a-b)^3+(a+b)^3=2a^3+6ab^2[/tex]            ...(i)

We have,

[tex]\left(\dfrac{1}{7}-4\sqrt{3}\right)^3+\left(\dfrac{1}{7}+4\sqrt{3}\right)^3 [/tex]

Using formula (i), the given expression can be written as:

[tex]=2\left(\dfrac{1}{7}\right)^3+6\left(\dfrac{1}{7}\right)\left(4\sqrt{3}\right)^2[/tex]

[tex]=2\times \dfrac{1}{343}+6\left(\dfrac{1}{7}\right)48[/tex]

[tex]=\dfrac{2+14112}{343}[/tex]

Which is the correct form of the partial fraction decomposition for the expression StartFraction 4 x cubed + 3 x squared Over (x + 1) squared (x squared + 7) squared EndFraction?

Answers

Given:

The expression is:

[tex]\dfrac{4x^3+3x^2}{(x+1)^2(x^2+7)}[/tex]

To find:

The correct form of the partial fraction decomposition for the given expression.

Solution:

We have,

[tex]\dfrac{4x^3+3x^2}{(x+1)^2(x^2+7)}[/tex]

By partial fraction decomposition, it can be written as:

[tex]\dfrac{4x^3+3x^2}{(x+1)^2(x^2+7)}=\dfrac{A}{x+1}+\dfrac{B}{(x+1)^2}+\dfrac{Cx+D}{x^2+7}[/tex]           ...(i)

[tex]\dfrac{4x^3+3x^2}{(x+1)^2(x^2+7)}=\dfrac{(x+1)^2(Cx+D)+(x+1)(x^2+7)A+(x^2+7)B}{(x+1)^2(x^2+7)}[/tex]

[tex]4x^3+3x^2=(x+1)^2(Cx+D)+(x+1)(x^2+7)A+(x^2+7)B[/tex]

[tex]4x^3+3x^2=x^3A+x^3C+x^2A+x^2B+2x^2C+x^2D+7xA+xC+2xD+7A+7B+D[/tex]

[tex]4x^3+3x^2=x^3(A+C)+x^2(A+B+2C+D)+x(7A+C+2D)+7A+7B+D[/tex]

On comparing both sides, we get

[tex]A+C=4[/tex]

[tex]A+B+2C+D=3[/tex]

[tex]7A+C+2D=0[/tex]

[tex]7A+7B+D=0[/tex]

On solving these equations, we get

[tex]A=\dfrac{23}{32},B=-\dfrac{1}{8},C=\dfrac{105}{32},D=-\dfrac{133}{32}[/tex]

Substituting these values in (i), we get

[tex]\dfrac{4x^3+3x^2}{(x+1)^2(x^2+7)}=\dfrac{\dfrac{23}{32}}{x+1}+\dfrac{-\dfrac{1}{8}}{(x+1)^2}+\dfrac{\dfrac{105}{32}x-\dfrac{133}{32}}{x^2+7}[/tex]

Therefore, the required partial fraction decomposition is:

[tex]\dfrac{4x^3+3x^2}{(x+1)^2(x^2+7)}=\dfrac{\dfrac{23}{32}}{x+1}+\dfrac{-\dfrac{1}{8}}{(x+1)^2}+\dfrac{\dfrac{105}{32}x-\dfrac{133}{32}}{x^2+7}[/tex]

f(x) = x2 – 3x – 2 is shifted 4 units left. The result is g(x). What is g(x)?

Answers

Answer:

Answer A: g(x) = (x + 4)² - 3(x + 4) - 2

Step-by-step explanation:

f(x) + n - shift the graph n units up

f(x) - n - shift the graph n units down

f(x + n) - shift the graph n units left

f(x - n) - shift the graph n units right

f(x) = x² - 3x - 2.

shift 4 units left, f(x + 4) = (x + 4)² - 3(x + 4) - 2

Answer A: g(x) = (x + 4)² - 3(x + 4) - 2
