If the average rate of human hair growth is 12 mm per month, approximately how many years will it take to grow hair that is 1 m in length? Round of the nearest year
Answer:
7
Step-by-step explanation:
1) 1 m = 1000 mm, then to calculate the required time in months
2) 1000/12≈83.3 [months];
3) if 12 months=1year, then 83.3 months are 83.3/12≈6.94=7 [years].
It costs $5.25 to rent bowling shoes. Each game costs $3.00. You have $26.25. How many games can you bowl?
First lets write an equation to help us solve this.
26.25=3x+5.25
x=7
26.25 - 5.25 = 21.
21/3 = 7.
Answer:
You can bowl 7 games.
Step-by-step explanation:
To begin, you need shoes.
-$5.25
So, we would do $26.25 minus the amount for shoes $5.25
$26.25-$5.25 = $21
You now have $21 to spend on bowling the games. Since it is $3 each game, we can do the equation $21 = $3x. We can do this becuase you have $21 to spend and each game costs $3. So we can put x for how many games and 3 as the price of each game. Now, we simplify to get x alone. This will be how many games you can bowl.
21 = 3x
Divide by 3 on both sides
7 = x
So, you can bowl 7 games.
Which relation represents the pattern in the table of values?
y = 3x - 2
y = 3x + 2
y = 2x + 3
y = 2x - 3
Answer:
y = 3x + 2
Step-by-step explanation:
The easiest way to do this, would be to substitute a point (e.g., (2,8)) into your equations to find the one that is true.
(2, 8)
y = 3x - 2
8 = 3(2) - 2
8 = 6 - 2
8 = 4
This statement is false
(2, 8)
y = 3x + 2
8 = 3(2) + 2
8 = 6 + 2
8 = 8
This statement is true
(2, 8)
y = 2x - 3
8 = 2(2) - 3
8 = 4 - 3
8 = 1
This statement is false
(2, 8)
y = 2x + 3
8 = 2(2) + 3
8 = 4 + 3
8 = 7
Therefore, b is the correct answer.
Hope this helps!

What is the median mean mode and range of 1,3,5,8,10?
Answer:
Below!
Step-by-step explanation:
Given data: 1, 3, 5, 8, 10
Determining the median of the data:
The median is the "middle number" of the data in ascending or descending order. In this case, the data is already in ascending form. Since the number of digits in the data is ODD, we will use to formula (n + 1)/2 (where "n" is the number of digits) to determine the median.
⇒ (n + 1)/2⇒ (5 + 1)/2⇒ (6)/2⇒ 3Determining the mean of the data:
The mean of the data is the average number of the data (as said above). To determine the average number (mean), we need to sum the digits in the data and divide it by the total digits in the data. In this case, the sum of the digits in the data is 27 and the total digits in the data is 5.
⇒ Mean = (27)/5⇒ Mean = 5.4Determining the mode of the data:
The mode of the data is the number that has repeated the most.
⇒ "1" has been repeated once⇒ "3" has been repeated once⇒ "5" has been repeated once⇒ "8" has been repeated once⇒ "10" has been repeated onceSince all the digits in the data has repeated once, all the numbers in the data (1, 3, 4, 8, 10) are the mode.
Determining the range of the data:
The range of the data is the difference of the largest and smallest number (As said above).
⇒ Range = Largest number - Smallest number⇒ Range = 10 - 1⇒ Range = 9Answer:
Median: 5
Mean: 5.4
Mode: 1, 3, 5, 8, 10
Range: 9
Step-by-step explanation:
Median: the middle value.
Mean: the average (found by adding up all of the numbers and dividing them by the number of numbers in the data set).
Mode: the number that is most frequent.
Range: the difference between the biggest and smallest values.
First, make sure your data set is in numerical order: 1, 3, 5, 8, 10
Median: 5
1, 3, 5, 8, 10
Mean: 5.4
1 + 3 + 5 + 8 + 10 = 27
27/5 = 5.4
Mode: 1, 3, 5, 8, 10
1, 3, 5, 8, 10
All of them, as they all appear once.
Range: 9
10 - 1 = 9

is 5/74 rational or irrational?
Answer:
Rational
Step-by-step explanation:
5.74 is the same as 5.74 over 1. In other words, 5.74 can be written with a numerator and denominator, like this:
5.74 = 5.74/1
5.74 x 100/ 1 x 100
You can multiply the numerator and denominator of any fraction by the same number and keep the value of the fraction the same. Here we will multiply the numerator and denominator by 100 to get rid of the decimal point.
5.74 × 100/ 1 × 100
When we calculate the numerator and the denominator above, we get this fraction:
574/100
The fraction above is the same as 5.74. Furthermore, the numerator and the denominator of the fraction above are integers. Therefore, we can conclude that the answer to "Is 5.74 a rational number?" is yes.

given by the equation s = -2.7t^2 + 40t + 6.5, where t is the number of seconds after the ball was thrown. Complete parts a and b.
a. After how many seconds is the ball 14 ft above the moon's surface?
After ____ seconds the ball will be 14 ft above the moon's surface.
(Round to the nearest hundredth as needed. Use a comma to separate answers as needed.)
Answer: 0.19s and 14.6s
Step-by-step explanation:
The distance of the ball at any time is given by the function s(t). For now, you can ignore all the details about the height of the man and the intial velocity of the ball. We only care about what time 't' will the ball be 14 feet off the ground. In math terms, they are asking when:
[tex]s(t)=14[/tex]
Where:
[tex]s(t)=-2.7t^2+40t+6.5=14[/tex]
Subtract 14 on both sides:
[tex]s(t)=-2.7t^2+40t-7.5=0[/tex]
Use the quadratic formula to solve for the variable 't'. This will give the possible time values where the ball will be 14 feet off the ground:
[tex]t=-b+\sqrt{b^2-4ac} /2a[/tex]
[tex]t=-b-\sqrt{b^2-4ac} /2a[/tex]
[tex]a=-2.7[/tex]
[tex]b=40[/tex]
[tex]c=-7.5[/tex]
Therefore:
[tex]t=(-40)+\sqrt{40^2-4(-2.7)(-7.5)} /2(-2.7)=0.19s[/tex]
[tex]t=-40-\sqrt{40^2-4(-2.7)(-7.5)} /2(-2.7)=14.6s[/tex]
This is saying the ball almost immediately hits 14 feet given the intial velocity, then it reaches its peak and falls back down to 14 feet again, where it will eventually hit the ground again

If Mike walks to school and rides his bicycle back at home it takes him 90 minutes. If he rides his bicycle both ways it takes him 30 minutes. How long would it take the trip to school and back walking? Assume he walks at a constant speed and also rides the bicycle at a constant speed.
Answer:
2 hours 30 minutes
Step-by-step explanation:
Mike rides to School and back for 30 minutes. It means that he rides to school 15 minutes.
90min-15min = 75min (one way, walking)
2*75min = 150min = 2h 30min
Mike's will walk to school and back home 2h 30min

Emiyjah wants to buy a new smartphone that costs $495. She has already saved $75.
6A) Write an inequality that shows the amount of money, m, that Emiyjah still needs to save before she can buy the smartphone.
Make sure you include the 495, the 75, the m, and an inequality symbol NOT an equal sign!
Answer:
m + 75 > 495
Step-by-step explanation:
After saving an additional amount m, Emiyjah will have a total savings of ...
m + 75
She needs to have that amount be greater than the cost of the smartphone, so she requires ...
m +75 > 495

1. When you go to a party or other gathering you shake hands with many people. The following is a formula that will predict how many hand shakes take place if every person shakes hands with every other person only once.
s = n(n - 1)/ 2
where S is the total number of hand shakes and n is the total number of people at the party.
(a) Express this formula in words.
(b) How many hand shakes will occur if there are 12 people present?
Answer:
s = 66
Step-by-step explanation:
S = number of shakes
N = number of people
(N-1) = takes yourself out of the equation
÷ 2 = shaking hands with everyother person
so when 12 people present:
s = 12(12-1) /2
s = 12(11) /2
s = 132 /2
s = 66
Answer:
This is called an exponential function, values are inserted to variables where applicable, aka, n = total number of people at the party, if there are only 12 people, (b:) insert into function where 'n' appears: (12(12-1)/2 = 66. This means 66 handshakes will occur if there are 12 people present.

Using linear functions, it is found that the two plans will donate the same amount for 4 miles.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, the functions for the amount donated with n miles are given by:
f1(n) = 10 + 0.5n.f2(n) = 4 + 2n.They will donate the same amount for n miles as such:
f1(n) = f2(n).
10 + 0.5n = 4 + 2n.
