Because in decimals theres tens place, 100s place, 1000s place, etc. going from left to right after the decimal point which is the "and" in the statement. In this decimal theres only 3 numbers after the decimal point so that means to goes to the 1000s place.

Use properties of Logarithms to simplify the limit:

[tex]\lim_{x \to \0^+}[/tex]e^3/x(e^x+x)

Move the limit to the exponent:

e^x[tex]\lim_{x \to \0^+}[/tex]3/xln(e^x+x)

Rewrite as:

e^x[tex]\lim_{x \to \0^+}[/tex]3ln(e^x+x)/x

The length of the expert trail is 800 meters. We can find our answer by using given tape diagram and simple mathematical calculations.

What is tape diagram?

A tape diagram is a visual model resembling a piece of tape, that is used to assist with the calculations of ratios and addition, subtraction and commonly multiplication.

Here,

Length of the Beginner trail is 200 meters

And also expert trail is 4 times to Beginner trail.

So, Expert trail = 4 * Length of beginner trail.

     Expert trail = 4* 200

                        = 800 meters.

Hence, we get the answer.

Step-by-step explanation:

Answer:Alexia swam  7,560meters in 2 weeks

Step-by-step explanation:

Step 1

7 days = 1 week

therefore 2 weeks = 7 x 2 = 14 days

Step 2

Each day  Alexia swam =  0.54 kilometres

So in 14 days( 2 weeks) She swam = 14 x 0.54 km= 7.56km

Answer is needed in meters

so 1000 m = 1km

Therefore 7.56 km = 7.56km x 1000=7,560meters

Answer:

d + 85

Step-by-step explanation:

Look at it like this,

suppose you have 1 DVD, and the mother buys 85 DVDs then you have 1 + 85 = 86 DVDS

or when you have 2 DVDs, then you have 2 + 85 = 87 DVDs afterwards.

notice that you always take the number of DVDs you already have, and add 85 to it.

d is just a number, but you just don't know it yet. you can change d by any number, and you know d+85 is the number of DVDs afterwards

Answer: B. It is a perfect square

Step-by-step explanation:

Radical Expressions

Melissa multiplied [tex]\sqrt{a}[/tex] and [tex]\sqrt{b}[/tex] and got a rational number.

We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.

We can write that product like:

[tex]\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}[/tex]

If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.

Answer: B. It is a perfect square

Answer:

[tex]T = 600[/tex]

Step-by-step explanation:

Represent the table with T, couch with C an umbrella with U

We have the following:

[tex]2C + U + T = 1875[/tex]

[tex]C + T = 1075[/tex]

[tex]2C + U = 1275[/tex]

Required

Determine the cost of a table

Make T [tex]the\ subject\[/tex] [tex]in\ the[/tex] first equation

[tex]T = 1875 - (2C + U)[/tex]

In the third equation, we have that: [tex]2C + U = 1275[/tex]

By substituting 1275 for 2C + U

[tex]T = 1875 - (2C + U)[/tex] becomes

[tex]T = 1875 - 1275[/tex]

[tex]T = 600[/tex]

Hence, a table costs $600

Answer:

$3.90

Step-by-step explanation:

its B

The price of the ticket at which the student councils will maximize the profit is $3.90.

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of students = 480

Lowest ticket price = $3

Ticket price = $4.20

This means,

4.20 - 3 = 1.20

There is an increase of $1.20 which is 0.20 x 6 = $1.20.

The number of students who attended when the ticket price is $4.20.

= 480 - (6 x 20)

= 480 - 120

= 360

Profit:

= 360 x 4.20

= $1512

Ticket price = $3.90

This means,

3.90 - 3 = 0.90

There is an increase of $0.90 which is 0.20 x 4.5 = $0.90.

The number of students who attended when the ticket price is $3.90.

= 480 - (4.5 x 20)

= 480 - 90

= 390

Profit:

= 390 x 3.90

= $1521

Now,

Ticket price = $3.50

This means,

3.50 - 3 = 0.50

There is an increase of $0.50 which is 0.20 x 2.5 = $0.50.

The number of students who attended when the ticket price is $3.50.

= 480 - (2.5 x 20)

= 480 - 50

= 430

Profit:

= 430 x 3.50

= $1505

Now,

Ticket price = $4.00

This means,

4 - 3 = 1

There is an increase of $1 which is 0.20 x 5 = $1.

The number of students who attended when the ticket price is $4.20.

= 480 - (5 x 20)

= 480 - 100

= 380

Profit:

= 380 x 4.20

= $1520

We see that,

The profit is highest when the ticket price is $3.90.

Thus,

$4 ticket price will maximize the student council's profit.

Answer:

Step-by-step explanation:

Answer:

A: 336 km

B: 14 L

Step-by-step explanation:

Use a proportion

210 km / 5 L = x / 8L         Cross multiply

8*210  = 5 x

1680  = 5x

x = 1680 / 5

x = 336 km

===============

210 /5 = 588/x                   Cross multiply

210x = 588 * 5

210x = 2940                     Divide by 210

x = 2940/210

x = 14 L

cos θ = [tex]\frac{adjacent}{hypotenuse} = \frac{38}{47}[/tex]

θ = cos-1 (38/47)
