Answer 1

Answer:

v=31

Step-by-step explanation:

Average speed is total distance/total time.

We can rearrange this equation to find total distance:

Distance = time x speed

Our given time is 14 hours and our average speed is 13km/h, therefore the distance travelled 14x13=182m.

On a speed-time graph, the distance is found by finding area under the line on the graph. So to find v, we can find the area for the other sections first and then use the remainder to find v.

The total distances for the other 3 sections are: 4x6 + 6x12 + 4x12 = 24+72+24=120

182-144 = 38

This means that the area of the triangle with height v-12 has an area of 38.

Area of a triangle = 1/2bh

38=1/2(4)h

38=2h

h=19

The distance between v and 12 is 19 so the full value of v is 19+12=31

v = 31

Answer:

10

Step-by-step explanation:

24 ÷ 3 = 8 so one third is 8

24 ÷ 4 = 6 so one fourth is 6

8 + 6 = 14 (14 people brought drinks or dessert)

24 - 14 = 10

A community center charges x dollars for a summer activity if individuals are signed up before the day of the activity. Individuals who sign up the day of the activity are charged a fee of x +0.20x dollars. Which expression also represents the fee for signing up the day of the activity, and what does it mean about the fee?
​

Answers

Answer: 1.2 individual signing up the day of the activitiy get charged 20% more

Step-by-step explanation:

We have a community center that charges x dollars for a summer activity if individuals are signed up before the day of the activity but if  individuals who sign up on the day of the activity are charged a fee of x + 0.20x dollars.

We have to determine which expression represents the fee for signing up the day of the activity and investigate what does it mean about the fee.

What do you understand by the Equation Modelling of the process?

Equation modelling of a process is a way to formulate the given process mathematically. Generally, it is used in such problems where something is produced on giving some input.

According to question, we have the following equation describing the charging rates -

f(x) = x + 0.2x = x + [tex]\frac{1}{5}x[/tex]

In this the expression, the part  [tex]\frac{1}{5}x[/tex] represents the fee for signing up on the day of the activity.

It also indicates that if you you are late for sign up and you are signing on the day of the activity then you will have to pay an extra fine of [tex]\frac{1}{5}[/tex] times of the fees if you signed up before the day.

Mark starts a rock climb when he is 1 mile above sea level. He can climb at the rate of 1.5 miles per hour. Which of the following functions would express Mark's height above sea level over time?
A. f( x) = 1.5 x
B. f( x) = 2.5 x
C. f( x) = 1 + 1.5 x

Answers

Answer:

C.

Step-by-step explanation:

Its C because you start out at 1 mile above sea level, then each time Mark climbs he goes up 1.5 miles per hour. f(x)= 1(starting point) + 1.15x (miles per hour).

It would be C because the 1.5x represents the miles per hour since that changes and you would add 1 because he is 1 mile above sea level

Find the value of b, the y-intercept.


b = ???

Answers

Answer:

b = 3/4

Step-by-step explanation:

Using point slope: y - y1 = m(x - x1).

Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.

0.2 = 1/5, so 1/5 * 1/4 = 1/20

Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → 3/4

b = 3/4

Using point slope: y - y1 = m(x - x1).

Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.

0.2 = 1/5, so 1/5 * 1/4 = 1/20

Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → 3/4

Answers

Answer:

The price would now be $59.40

Step-by-step explanation:

$59.4 is the sale price of the game system.

The selling price is how much a buyer pays for a product or service.

Given,

A toy store is having a sale. A video game system has an original price of $99.

It is on sale for 40% off the original price.

We need to find how much 40% of $99.

40/100×99=0.4×99=39.6.

So sale price of the game system is $99-$39.6=$59.4.

Now, technology is changing the way that people receive and react to news stories. News has become a community affair, instead of a job in the hands of the powerful news editors. Through the Internet, people can search for opinionated or unbiased news on just about every topic under the sun. Today, the powerful are not the news editors but the news bloggers. A Web log, or blog, is a space for a person to write down his or her ideas, thoughts, feelings, or even news. Many people in the U.S. have personal blogs, in which they share parts of their lives with total strangers around the world. Now, blogs are becoming increasingly important in the world of news. Reporters caught in the thick of battle can immediately post their thoughts and feelings on blogs. Amateur writers can become instant celebrities from their focus on a particular news-worthy subject. So what are these blogs doing to news? Simply put, they are personalizing news. Blogs are making it easier and faster for readers and Internet surfers to get a behind-the-scenes look at a story. Blogs are also making it easier for people to start conversations about news events, whether that is through comments made about a particular entry or a message board attached to the blog. The Internet in general has allowed people the opportunity to really bring news into their lives. Blogs are just one more way for people to connect to a news story. Unfortunately, blogs have their problems. If they are not attached to a well-known news Web site, like Reuters, CNN, or even your local paper, the blogs are often not fact-checked. Blogs are often more about a person's opinion about an event or a personal attachment to an event or story. They are less about the straight facts and more about the personal element of the story. People have to be very careful when reading blogs not attached to familiar news companies. The right blog can be an enjoyable and personal way to experience news and understand what is going on in the world. From a reporter on the campaign trail to a family living in Iraq, readers can find out many different views on a wide variety of stories. Blogs are just one more way for people to personalize and identify with news they might not otherwise see or hear about. Take a few minutes to find a blog that fits your interests.
