A map of a highway has a scale of 2 inches =27 miles. The length of the highway on the map is 9 inches. There are 7 rest stops equally spaced on the​ highway, including one at each end. You are making a new map with a scale of 1 inch=30 miles . How far apart are the rest stops on the new​ map?

Answers

Answer: 0.675 inches apart

Step-by-step explanation:

27/2=13.5

7 spots-1 spot( because one is on the end of the map at 0)

9/6=1.5

1.5•13.5=20.25

20.25/30=0.675

A cell phone provider offers a plan that costs ​$40 per month plus ​$0.10 per text message sent or received. A comparable plan costs ​$60 per month but offers unlimited text messaging. If you send or receive an average of 50 text messages each​ month, which plan would you​ choose? Why?

Answers

Okay so $40 a month, 10 cents per message.

10 cents times 50 messages is only 5 dollars.

So, it would be around $45 a month.

If I only sent around that many messages a month, I would just go with the $40 a month, cause you can save around $15.

9 Pencils cost $7.74
Which equation would help determine the cost of 6 pencils?

Answers

Answer: $5.16

Explanation: (in my way)
x= 6x7.74/9
Multiply 6 x 7.74
x=46.44/9
Divide
x=$5.16
$7.74 divided by 9 equals $0.86 per pencil. so 6 pencils would be 6 times 0.86 which equals $5.16 for 6 pencils.

(7.74 / 9) • 6 = Cost of 6 pencils

Answers

Answer:

18 square yards of rubber flooring

Step-by-step explanation:

We can look at the model as a 16x13 rectangle with a 6x9 rectangle cut out of it. So we can just find the area of the 16x13 rectangle and subtract the area of the 6x9 rectangle:

16*13=208

6*9=54

208-54=154

So the area of the floor is 154 square feet.

BUT the problem asks how many square YARDS of rubber flooring are required to cover the floor. Because there are 3 feet in a yard, there are 3^2 square feet in a square yard, or 9 square feet in a square yard. So we need to divide 154 by 9, which is 17 1^9. Because you can only buy 1 square yard of rubber flooring at a time, we need to buy 18 yards of rubber flooring to cover the floor.

I hope I explained this well enough. Happy mathing!

Edit: I just stood up too fast. The second picture is VERY true.

Answer:

154 ft.^2

Step-by-step explanation:

13 times 16 = 208

Answer:

[tex]4 \frac{13}{30}[/tex] (4 13/30)

Steps :

1) Convert 1 1/6 and 3 4/5 to mixed numbers.

1 1/6 is 7/6 in mixed number and 3 4/5 is 19/5 in mixed number.

2) multiply 7/6 x 19/5, which is 7 x 19/6 x 5.

7 x 19 is 133 and 6 x 5, so it would be 133/30

3) Change 133/30 to a mixed number, which would be [tex]4\frac{13}{30}[/tex] ( 4 13/30)

To get the answer, you need to do 133/30, which is 4.43333, witch would be 4 13/30 ([tex]4\frac{13}{30}[/tex])

Other Questions
How does the reunion affect paolos parents and benjamin There is scientific research to back up the idea that school should start later for middle and high school students. Beginning in their adolescent years, students' sleep patterns change because they become more focused in the evening and stay up later. This requires that they sleep later in the morning since, according to research, teenagers need 810 hours of sleep. Not getting enough sleep can lead to health risks, but it also has consequences for teenagers and their academics. Students who do not get enough sleep have a harder time staying alert and remaining focused in class, which can lead to poorer grades. Furthermore, lack of sleep can lead to increased stress levels and prevent students from retaining information, leading to problem-solving troubles. Teenagers who do not get enough sleep suffer from poor academic performance. Physical problems, such as lack of physical alertness, can also be the result of teenagers not getting adequate sleep. Research also shows that students who do not get enough sleep can be overweight. While many middle and high schools begin before 8:30, they should modify their schedules. Experts suggest that these schools begin no earlier than 8:30 in the morning. This allows for students to sleep later in the morning, which matches the scientifically proven sleep cycles of teenagers. Question: Which sentence would be the best conclusion to the essay? a The needs of students should not be the driving force behind schools modifying schedules. b Allowing students to sleep in will benefit schools and later start times should be put in place. c For students to be successful, schools should understand the importance of students' physical needs. d Middle and high school students cant stay focused if they dont have enough sleep.
