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.
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.

Combine the two expressions found in parts C and D to relate a, c, A, and C. Rewrite the expression as an equality between two ratios. Show your work.
Answer:
BD = c sin A and BD = a sin C.
Therefore, a sin C = c sin A.
Divide both sides by sin A × sin C to get A/sin A = C/sin C

What is the solution of the equation?
4(y+2)=32
A 4
B 6
C -10
D 10
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.

B. ln(3.1 + 3)
OC. In(x4 - x + 3)
D. ln(111)
The required simplified value of the given expression is ln[3x³]. Option A is correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Given expression,
= 4 lnx + ln 3 - ln x
= ln x⁴ + ln [3 / x] [since ln a - ln b = ln [a / b]]
= ln [3x⁴/x] [since lna + ln b = ln ab]
= ln[3x³]
Thus, the required simplified value of the given expression is ln[3x³]. Option A is correct.

y is directly proportional to x^ . if y=12 when x=2 find, y when x=5
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

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
