.65,6.5,2/3,1/2 least to greatest
Answer: 1/2 < 0.65 < 2/3 < 6.5
Step-by-step explanation:
Given information
0.65, 6.5, 2/3, 1/2
Convert fractions into decimals
0.65 = 0.65
6.5 = 6.5
2/3 = 0.67 (Rounded to hundredth place)
1/2 = 0.5
Arrange decimals from least to greatest
0.5 < 0.65 < 0.67 < 6.5
Convert terms back to the given form
1/2 < 0.65 < 2/3 < 6.5
Hope this helps!! :)

Nikki's cousin lives 60 miles away, so Nikki decided
to take the train to visit him. If the trip took
2 hours, how many miles per hour did the train
travel?
Answer:
30
Step-by-step explanation:
just divide 60 by 2
If the distance between Nikki's cousin and Nikki is 60 miles and covered in 2 hours then the speed of the train is 30 miles per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
[tex]\rm Speed = \dfrac{Distance}{Time}[/tex]
Nikki's cousin lives 60 miles away, so Nikki decided to take the train to visit him. If the trip took 2 hours. Then the speed of the train will be
[tex]\rm Speed = \dfrac{60}{2}\\\\Speed = 30 \ miles/hour[/tex]

The graph shows the number of appearances of hockey teams in the Stanley Cup Finals.
a. Write the ratio that compares the appearances made by the Rangers to the appearances made by the Canadiens in simplest form. Then explain its meaning
Answer:
Step-by-step explanation:
Important fact: much as I hate to admit it, in all professional sports, there is no team that has made as many appearances in the sports final as the Canadiens.
The ratio you want is 10/32 = 5/16.
The ratio means that for every 5 appearances the rangers made, the Canadiens made 16 appearances.

Answer:
a.
MP3 player: 88%
Video game player: 92%
b.
MP3 player: 75 minutes
Video game player: 67 minutes
Step-by-step explanation:
a.
MP3 player
- Already has 40%
- Each 15 minutes additional 12%
--> An hour = (60/15)*12 = 48 (%)
--> After an hour charged = 40 + 48 = 88%
Video game player
- Already has 20%
- Each 10 minutes additional 12%
--> An hour = (60/10)*12 = 72 (%)
--> After an hour charged = 20 + 72 = 92 (%)
b. To charges 100 minutes:
MP3 player
100 = 40 + ((x/15*12)
--> x = 75 (minutes)
Video game player
100 = 20 + ((x/10*12)
--> x = 67 (minutes)
SOMEONE HELP ME PLEASE
Answer:
6.3 cm
Step-by-step explanation:
The distance from each centimeter is divided into 10 parts. Point A starts at 0 and goes until right before 6.5. The big line between each whole number signifies that you are halfway through the centimeter. As you can see, point B is right before a big line, so can't be bigger than 6.5 nor equal. The only option that fits this is 6.3 cm
The answer is 6.3 cm

x = -15
Step-by-step explanation:
Subtract x on both sides
x + 5 = -10
Subtract 5 on both sides
x = -15
Check work:
2(-15) + 5 = -15 - 10

Step-by-step explanation:
also not sure if you wanted the values for n
edit:
7. n/2 = 16
8. 2n + 4 = 52
9. 2(n + 5) = 17
10. 3n - 12 = 5
Answer:
7. 32
8. 24
9. 3.5
10. 5.6
Step-by-step explanation:
7. write the equation: n/2=16. Cross multiply.
8. write the equation: 52= 4+2n. Move 4 to the other side and subtract from 52: 48= 2n. Divide both sides by 2.
9. write the equation: 2(5+n)=17. Use the distributive property. Move 10 to the other side and subtract from 17: 2n=7. Divide both sides by 2.
10. write the equation 3n-12=5. move -12 over and add to 5: 3n=17. Divide both sides by 3.

-2(1-5v)=-(2-4v)
Answer:
v = 0
Step-by-step explanation:
-2 (1 - 5v) = - (2 - 4v)
Simplify the equation down to the following:
-2 + 10v = -2 + 4v
Do the inverse operation for each side:
10v = 0 + 4v
6v = 0
6v/0 = 0/0

How can I solve this?
: 2(2x-7)+2(4x+3)=112
Step-by-step explanation:
Answer: Third Choice. 112 = 2 (2x - 7) + 2 (4x + 3)
Concept:
Here, we need to know how to find the perimeter of a rectangle.
Perimeter (rectangle) = 2l + 2w
l = length
w = width
Solve:
Given information
l = 2x - 7
w = 4x + 3
Perimeter = 112 cm
Given expression
Perimeter = 2l + 2w
Substitute values into the expression
[tex]\boxed{112 = 2 (2x - 7) + 2 (4x + 3)}[/tex]
Expand parentheses
112 = 4x - 14 + 8x + 6
Combine like terms
112 = (4x + 8x) + (6 - 14)
112 = 12x - 8
Add 8 on both sides
112 + 8 - 12x - 8 + 8
120 = 12x
Divide 12 on both sides
120 / 12 = 12x / 12
[tex]\boxed{x=10}[/tex]

Is the mean greater than, less than, or equal to the median? Explain your reasoning.
Answer:
equal to
Step-by-step:
Again, the mean reflects the slanted the most.
To summarize, generally if the distribution of data is slanted to the left, the mean is less than the median, which is often less than the mode. If the distribution of data is slanted to the right, the mode is often less than the median, which is less than the mean.
Answer:
Equal
Step-by-step explanation:
The median is the midmoint of all points (as many values below as above this value). The mean is the (sum of values) / (count of values). Since every value has the exact same count, the mean and median will be the same.

35. The circumference of a circle is 67
inches. What is the area of the circle?
A=2
Answer:
B
Step-by-step explanation:
hopefully it makes sense and is visible:)
====================================================
Work Shown:
C = 2*pi*r .... circumference equation
6pi = 2pi*r .... replace C with the given circle perimeter
6 = 2r .... divide both sides by pi, they cancel
6/2 = r
3 = r
r = 3 ... is the radius
------------
A = pi*r^2 .... area of circle equation
A = pi*3^2
A = pi*9
A = 9pi .... which points to choice B as the final answer

A bag has 14 yellow marbles and 4 red marbles. Half of the red marbles are made of glass. A marble is selected at random from the bag. What is the probability that it is a red, glass marble?
Answer:
2/18, or 1/9
Step-by-step explanation:
Lets start by finding out how many red, glass marbles there are.
Half of the red marbles of glass, and there are four red marbles. All we need to do is divide 4 by 2.
4/2=2
There are two glass marbles.
Now we just need to add the number of red marbles to yellow marbles. That would be 14+4, which is 18.
In conclusion, there are 2 red marbles, and 18 marbles in total, so it would be 2/18. Simplified, it would be 1/9.
