Answer:
0.2 inches
Step-by-step explanation:
12.5 weeks = 2.5 inches
1 week = p inches
Cross multiply
12.5p = 2.5
Divide both sides by 12.5
p = 2.5 / 12.5
p = 0.2 inches
Hence, the length grown in 1 week is 0.2 inches

The ratio of good guys to bad guys was 15 to 4. If there were 75 good guys, how many bad guys were there ?
[tex]\begin{array}{ccll} \stackrel{guys}{good}&\stackrel{guys}{bad}\\ \cline{1-2} 15&4\\ 75&x \end{array}\implies \cfrac{15}{75}=\cfrac{4}{x}\implies \cfrac{1}{5}=\cfrac{4}{x}\implies x = 20[/tex]
Number of bad guys = 12
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given,
Ratio of good to bad guys = 15:4 = 15/4
No. of good guys = 75
Let the no. of guys be x
⇒ 15:4 = 75:x
⇒ 15/4 = 75/x
Cross multiplying
15 x = 75×4
x = (75/15)×4
No. of bad guys = (75/15)×4
= 3 × 4
No. of bad guys = 12
Hence, there are 12 bad guys.

Billy invests $5,000 in an account at 4.2% for 15 years, compounded monthly. Assuming no other deposits or withdrawals are made, how much will Billy have at the end of 15 years?
The amount Billy has at the end of the 15 years is $9,377.73.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P[tex](1 + r/n)^{nt}[/tex]
P = principal
r = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $5000
r = 4.2%
t = 15 years
n = 12
A = P[tex](1 + r/n)^{nt}[/tex]
A = 5000 [tex](1 + 0.0035)^{180}[/tex]
A = 5000 x [tex]1.0035^{180}[/tex]
A = $9,377.73
Thus,
Billy has $9,377.73 at the end of the 15 years.

Sara says, "If you subtract 17 from my number and multiply the difference by - 4, the result is
- 60." What is Sara's number?
Answer:
32
Step-by-step explanation:
ok to the result is - 60 she said. So then we know that in order to get -60, you had to subtract 17 from the original number and multiply by -4.
equation is this: (x-17)×-4= -60
Next, we solve using pemdas!
x-17=[tex]\frac{-60}{-4}[/tex] (keep in mind that a negative cancels out a negative!)
add 17 to both sides
x= [tex]\frac{-60}{-4}[/tex]+17
So then now that you have the new equation you simplify!

Which statements are true about the data in this table? Select all that apply.
The rate of change for the data is $12 per hour. $12 is also the constant of proportionality
If you graph the data, it would pass through the origin (0,0)
The data represent a direct variation and can be modeled by the function rule y = 12.
The data indicate a rate that is not constant
The rate of change for the data is $24 per hour. The data representa direct variation and can be modeled by the function ruley-242
The table is an illustration of a proportional relationship. and can be modeled by the function rule y = 12x
The entries of the table is given as:
Hours Earnings
4 48
6 72
10 120
20 240
Start by calculating the rate (m) of the function
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{72 - 48}{6-4}[/tex]
[tex]m = \frac{24}{2}[/tex]
[tex]m = 12[/tex]
The equation of the table is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = 12(x - 4) + 48[/tex]
[tex]y = 12x - 48 + 48[/tex]
[tex]y = 12x[/tex]
[tex]y = 12x[/tex] means that, the following statements are true:

The mall is located 2.4 kilometers north of jays house. The caffe shop is located 0.7 kilometers east of the mall. What is the distance between jays hair and the coffe shop
The distance between Jays hair and the caffe shop is 2.5 km.
Since the mall is located 2.4 kilometers north of jays house and the caffe shop is located 0.7 kilometers east of the mall, both directions are perpendicular. So, the distance between Jays hair and the caffe shop forms the hypotenuse side of this right angled triangle.
So, using Pythagoras' theorem, we find the hypotenuse side of this triangle, L.
Pythagoras' theorem states that the sum of squares of the sides of a right angled triangle equal the square of the hypotenuse side.
So, L = √[(2.4 km)² + (0.7 km)²]
L = √[(5.76 km² + 0.49 km²]
L = √(6.25 km²)
L = 2.5 km
So, the distance between Jays hair and the caffe shop is 2.5 km.

Whose statement is correct based on the expected value?
Answer: neither statement is correct
Step-by-step explanation:
on Khan Academy
The statement by Tom "A player will most likely get 17.5 " is correct based on expected value .
What is expected value?Expected value (also known as EV, expectation, average, or mean value) is a long-run average value of random variables. It also indicates the probability-weighted average of all possible values. Expected value is a commonly used financial concept.
According to the question
Tom and Rosie are designing a game.
In each turn, a player rolls five 6-sided dice and adds the numbers showing on each face to determine how many points they get that turn.
let X represent the sum in a given turn
the expected value of X is E(X)=17.5
As
expected value is also called mean value
i.e
highest value of sum = 6+6+6+6+6
= 30
Lowest value of sum = 1+1+1+1+1
= 5
Therefore,
Mean = [tex]\frac{30+5}{2}[/tex]
= 17.5
Now,
Tom says, "A player will most likely get 17.5
This statement is correct as per expected value which is mean value and it is 17.5 .
Rosie says, "Over 100 turns, we can expect a total of about 175
This statement is incorrect as per expected value as
expected value = 17.5
when 100 turn will happen it will
17.5 * 100
= 1750
Hence, The statement by Tom "A player will most likely get 17.5 " is correct based on expected value .

Answer: [tex]\boldsymbol{10\pi}[/tex]The distance between Mr. Tomback’s hometown and NYC is 36 centimeters on a road map. The map scale indicates that 5cm on the map represents 125 kilometers in real life. If Mr. Tomback drives at an average speed of 80 kilometers per hour, then how many hours will it take him to get home from NYC?
Answer:
First, we need to figure out the number of kilometers.
if 5 cm is equivalent to 125 kilometers in real life this means
1 cm is equivalent to 25 kilometers making the conversion much easier.
36 centimeters multiplied by 25 is 900, which means in real life the distance between Mr.Tomback's hometown and NYC is 900 kilometers.
900 km ÷ 80 kmh
= 11.25000000
= 11 hours
0.25000000 × 60
= 15.00000000
= 15 minutes
it will take him 11 hours and 15 minutes to get home to NYC
