Answer:

2nd answer, and 5 hours

Step-by-step explanation:

Section 1

The answer is the 2nd one down.  The tickets are selling at a rate of

floor tickets: 100/h; stand tickets:  75/h

Since the stand tickets were selling 150 in 2 hours, only 75 were sold per hour.

Section 2

There are only 375 stand tickets left to sell.

Every 2 hours 150 are sold or you can also say 75 per hour.

If you're selling 75 per hour, you would divide 375 by 75 which would give you 5 hours to sell out the stands tickets.

375/75 = 5 hours

Given f(x) = x^2 – 5x + k, and the remainder when f(x) is
divided by x - 7 is 34, then what is the value of k?

Answers

Step-by-step explanation:

f(7) = 34

7² -5(7) +k = 34

49-35+k =34

14+k = 34

k = 34-14

k = 20

Step-by-step explanation:

f(7) = 34

7² -5(7) +k = 34

49-35+k =34

14+k =34

k = 34-14

k = 20

I need a equation written for this pleeeeeaaaassse! The constant of proportionality is 2.
but I need an equation for this, I have an attachment for you to help. g= c is not correct sorry.

Answers

It sounds like your teacher wants g = 2c as the answer. The constant of proportionality simply tells us what to multiply the input variable by, to get the output variable.

It's similar to saying y = 2x, but we use c in place of x and use g in place of y.

A city planner wants to build a road parallel to 2nd Ave . What is the slope of the new road?

Answers

Answer:

Step-by-step explanation:

By inspection or finding points, we see that 2nd ave is perfectly flat, or in other words, has slope of 0.

If line 1 is parallel to line 2, it means their slopes are the same.

So, the new road parallel to 2nd ave has a slope of [tex]\boxed{0}[/tex].

Given m∠LMN=145 what is ∠XMN?

Answers

Answer:

(4x+5)°+(6x-10)°=145°

4x+6x+5-10=145°

10x-5=145°

10x=145+5

10x=150°

x=15

(6x-10)°=(6×15-10)°

=80°

The value of ∠XMN = 80.

What is angle?

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.

The value of total ∠LMN = 145.

∠LMN = ∠LMX +∠XMN

145 = (4x + 5) + (6x - 10)

145 = 4x + 5 + 6x - 10

145 = 10x -5

10x = 150

x = 15

Substitute the value of x in ∠XMN =  (6x - 10)

∠XMN =  6×15 - 10

            = 90 - 10

∠XMN = 80

Therefore, the value of the angle  ∠XMN = 80.

What is the completely factored form of this polynomial?
18x3 – 120x2 - 42x
Write the greatest common factor (GCF) first, and write all factors in standard form.

Answers

Answer:

6x(3x + 1)(x - 7)

Step-by-step explanation:

First look for the greatest common factor of the 3 terms.

The GCF is 6x, so

18x^3 – 120x^2 – 42x

= 6x(3x^2 - 20x - 7)

Now we look to factor the quadratic expression in the parentheses:

The first and last coefficients are multiplied

3 * -7 = -21.

We look for 2 numbers whose product is -21 and whose sum is -20:

They are -21 and + 1 , so we write:

6x(3x^2 - 21x + 1x - 7)

= 6x [ (3x(x - 7) + 1(x - 7)]    Note that x - 7 is common, so:

2.A baker has 400kg of flour on the first day of the month and uses no flour that day. How much will he have at closing time on the 17th day of the month, if he uses 24 kg each day after that?

Answers

1. At the end of the 5th week he would have saved a total of $700

2. The amount of flour he would have at the closing time on 17th of the month will be 16kg

1.

Azad amount = $500

He wants to go on a holiday but he lacks sufficient money. This means the $500 in his possession is not enough.

He decided to save $40 dollars per week for a number of weeks to make up the deposits.

let

w = number of weeks

Therefore, his saving for any number of weeks will be

40w

The amount he would have saved for 5 weeks will be

40×5=$200

The total amount in his possession at the end of the fifth week will be  200 + 500 = $700

2.

The baker has 400 kg of flour. The first day of the month he didn't use any flour. This means on the first day of that month the flour was still 400 kg. The amount he has on the 17th day of the month can be calculated below.

The 17th day simply implies he used the flour for 16 days, the first day of the month he didn't use anything. He uses 24 kg for each day. Therefore the amount he uses for 16 days will be

16×24=384 kg

The amount he has at the closing time of 17 days of the month will be

400kg - 384kg = 16kg

point Find the length of segment CD with C(2,3) and D (-3, 15​

Answers

Step-by-step explanation:

so, if the text is correct, the 2 points are

(2, 3) and (-3, 15).

the length of the line segment is the distance between both points.

did this we use Pythagoras for right-angled triangles.

c² = a² + b²

c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.

so,

distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169

distance = sqrt(169) = 13 = length of line segment

A horse travels at about 65 kph. At this rate, how far can it travel in 20 minutes

Answers

Answer:  Approximately 21.667 km

This value as a fraction is 65/3, but I think the decimal form is probably more practical in real world settings.

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

Work Shown:

20 min = 1/3 of an hour, since 20/60 = 1/3. In other words, there are three chunks of 20 minutes that make up a full hour.

distance = rate*time

distance = (65 kph)*(1/3 hr)

distance = (65*1/3) km

distance = (65/3) km

distance = 21.667 km which is approximate

Answer:

Distance rate=Rate x Time

Distance= (75 km/h) 20 mins

Convert 20 mins in hours= 1/3 h

Distance= (75 km/h) (1/3 h)= 25 km.....

3x+10=43 what is x to the what are the steps to equal X to the math equation

Answers

Answer:

x = 11

Step-by-step explanation:

When solving for x, you want to get the variable by itself on one side of the equation. The first step is to subtract 10 from both sides. 43-10=33. So, it should look like:

3x = 33

Divide both sides of the equation by 3 to get x alone. 33/3 equals 11. So x =11. Hope this helped and lmk if you have more questions!!
