y is directly proportional to x^ . if y=12 when x=2 find, y when x=5
Answers
Answer:
The value of y = 30 when x = 5
Step-by-step explanation:
We know that when 'y' varies directly proportional to 'x', we get the equation
y ∝ x
y = kx
k = y/x
where k is called the 'constant of direct variation'.
We are given
y = 12 when x = 2
so substituting y = 12 and x = 2 in the equation
k = y/x
k = 12/2
k = 6
Thus, the value of k = 6
We have to determine the value of y when x = 5
so substitute x = 5 and k = 6 in the equation
y = kx
y = 6(5)
y = 30
Therefore, the value of y = 30 when x = 5

D 10
Answers
Using the distributive property on the y and the 2, we get:
4y+8=32
Subtract the 8 on both sides and we get:
4y=24
Now, we can divide both sides by 4 and get the answer:
y=6
The answer is b
Answer:
[tex]\boxed{\sf{y=6}}[/tex]The answer is B. 6.Step-by-step explanation:
Use a distributive property.
Isolate the term of y from one side of the equation.
Distributive property:[tex]\Longrightarrow: \sf{A(B+C)=AB+AC}[/tex]
⇒: 4(y+2)=32
First, divide by 4 from both sides.
[tex]\Longrightarrow:\sf{\dfrac{4(y+2)}{4}=\dfrac{32}{4} }[/tex]
Solve.
⇒ 32/4=8
⇒ y+2=8
Subtract by 2 from both sides.
[tex]\Longrightarrow \sf{y+2-2=8-2}[/tex]
Solve.
Subtract the numbers from left to right.
8-2=6
y=6
Therefore, the correct answer is B. 6.I hope this helps you! Let me know if my answer is wrong or not.

Tara took a total of 45 quizzes over the course of 9 weeks. After attending 10 weeks of school this quarter, how many quizzes will Tara have taken in total? Assume the relationship is directly proportional.
Answers
Answer:
After 10 weeks, Tara will have taken 50 quizzes.
Step-by-step explanation:
Given that Tara took a total of 45 quizzes during the 9-week course, to determine the number of quizzes she will take after 10 weeks, taking into account that it is a proportional relationship, the following calculation must be performed:
(45/9) x 10 = X
5 x 10 = X
50 = X
So, after 10 weeks, Tara will have taken 50 quizzes.
In Tokyo, construction workers earn an average of ×420,000 (yen) per month with a standard deviation of ×20,000, while in Hamburg, Germany, construction workers earn an average of €3,200 (euros) per month with a standard deviation of €57. A worker making ×460,000 per month in Tokyo is earning relatively the same as one earning €3,300 per month in Hamburg?
Answers
Answer:
Since they have different z-scores, they are not earning relatively the same.
Step-by-step explanation:
We use z-scores to solve this question.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
In this question:
They will be earning relatively the same if they have the same z-score.
Tokyo:
Earns 460, mean 420, standard deviation 20. So [tex]X = 460, \mu = 420, \sigma = 20[/tex]. The z-score is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{460 - 420}{20}[/tex]
[tex]Z = 2[/tex]
Hamburg:
Earns 3300, mean 3200, standard deviation 57. So [tex]\mu = 3300, \sigma = 3200, \sigma = 57[/tex].
The z-score is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{3300 - 3200}{57}[/tex]
[tex]Z = 1.75[/tex]
Since they have different z-scores, they are not earning relatively the same.

Similar Triangles
Two triangles are similar if all of their corresponding side lengths are proportional to the same scale factor.
It's given triangles TPR and XPZ are similar, thus we can find the scale factor by comparing two corresponding sides with known lengths.
Sides TR and ZX are corresponding and the proportion of their side lengths is 15/9. The same proportion must be satisfied by the sides TP and XP:
[tex]\displaystyle \frac{15}{9}=\frac{25}{PX}[/tex]
PX and PZ are congruent, thus:
[tex]\displaystyle \frac{15}{9}=\frac{25}{PZ}[/tex]
[tex]\displaystyle PZ=25*\frac{9}{15}[/tex]
Calculating:
PZ = 15
