x = (6 * 11.2) / 7 = 9.6 answer
The value of x is 9.6.
To find the value of x to the nearest tenth, we can use the angle bisector theorem, which states that in a triangle, an angle bisector divides the opposite side into two segments that are proportional to the other two sides of the triangle.
Given that:
[tex]\[\frac{6.3}{5.4} = \frac{11.2}{x}\][/tex]
We can solve for x by cross-multiplying:
[tex]\[6.3 \cdot x = 5.4 \cdot 11.2\][/tex]
[tex]\[6.3x = 60.48\][/tex]
Now, divide both sides by 6.3 to isolate x:
[tex]\[x = \frac{60.48}{6.3}\][/tex]
[tex]\[x \approx 9.6\][/tex]
So, the value of x to the nearest tenth is 9.6. Therefore, the correct option is x = 9.6.

Find the values of x for which f(x) = g(x). (Enter your answers as a comma-separated list.) f(x) = x2, g(x) = x + 20
Answers
function f(x) = x²
function g(x) = x + 20
Solution:
Substitute f(x) with x² and substitute g(x) with (x + 20)
f(x) = g(x)
x² = x + 20
Move all terms to the left side. After moving, the positive ones become negative.
x² = x + 20
x² - x - 20 = 0
I break -x into -5x + 4x
x² - x - 20 = 0
x² - 5x + 4x - 20 = 0
Factorize x² - 5x
x² - 5x + 4x - 20 = 0
x(x - 5) + 4x - 20 = 0
Now factorize 4x - 20
x(x - 5) + 4x - 20 = 0
x(x - 5) + 4(x - 5) = 0
Separate (x - 5) from all terms using distributive property, the remaining one is (x + 4)
x(x - 5) + 4(x - 5) = 0
(x - 5)(x + 4) = 0
The solution
x - 5 = 0
x = 5
or
x + 4 = 0
x = -4
f(x) and g(x) will be both equal if the value of x is either 5 or -4

A) 180
B) 360
C) 36π
D) 360π
Answers
Answer:
Therefore ,(D) 360π inches.
Step-by-step explanation:
Given: A tire at the top of a hill starts rolling down the hill. If the diameter of the tire is 36 inches.
To find: How many inches has the tire rolled if it has rotated exactly 10 times down the hill.
Solution : We have given that diameter of tire = 36 inches.
Radius = [tex]\frac{Diameter}{2}[/tex]
Radius = [tex]\frac{36}{2}[/tex]
Radius = 18 inches.
Circumference of tire = 2 * π radius
Circumference of tire = 2 * π 18
= 36π
We need to rolled the tire 10 times down the hill
then, 10 * 36π = 360π inches.
Therefore ,(D) 360π inches.

Describe the graph of y=1/2x-10 -3 compared to the graph of y=1/x
Answers
Answer: The graphs are attached.
Step-by-step explanation: We are to describe the graph of the function [tex]y=\dfrac{1}{2x-10}-3[/tex] compared to the graph of the function [tex]y=\dfrac{1}{x}.[/tex]
The graphs of both the functions are shown in the attached figure.
We can see that the graph of the function [tex]y=\dfrac{1}{2x-10}-3[/tex] is stretched by a factor of 0.5, shifted 5 units to the right and 3 units downwards as compared to the graph of the function [tex]y=\dfrac{1}{x}.[/tex]
Answer:
The graph of [tex]y=\frac{1}{2x-10}-3[/tex] is the graph of [tex]y=\frac{1}{x}[/tex] stretched vertically, shifted right by 10 unit and shifted 3 unit down.
Step-by-step explanation:
Given : The graph of [tex]y=\frac{1}{2x-10}-3[/tex] compared to the graph of [tex]y=\frac{1}{x}[/tex]
To find : Describe the comparison of the graphs.
Solution :
Let the parent function be[tex]y_1=\frac{1}{x}[/tex]
Transformed function [tex]y_2=\frac{1}{2x-10}-3[/tex]
Vertically Stretch:
If y =f(x) , then y= a f(x) gives a vertical stretch if a> 1.
Multiplying the parent function by 2 means you are stretching it vertically,
i,e [tex]y_1=\frac{1}{x} \rightarrow \text{Vertically stretch by 2} \rightarrow \frac{1}{2x} [/tex]
Shifting right :
f(x)→f(x-b), graph is transformed by b unit
Subtracting 10 means you are moving it right by 10 units
[tex]y_1=\frac{1}{2x} \rightarrow \text{Shifted right by 10 units} \rightarrow y_1=\frac{1}{2x-10}[/tex]
Shifting down :
f(x)→f(x)-b , graph is transformed by b unit
Subtracting 3 means you are moving it down by 3 units
[tex]y_1=\frac{1}{2x-10} \rightarrow \text{Shifted down by 3 units} \rightarrow y_1=\frac{1}{2x-10}-3=y_2[/tex]
Refer the attached figure below.
The graph of [tex]y=\frac{1}{2x-10}-3[/tex] is the graph of [tex]y=\frac{1}{x}[/tex] stretched vertically, shifted right by 10 unit and shifted 3 unit down.

In the scenario where a pizza bill is split between Alice, Bob, Farhana, and Jamal, Farhana ends up paying the most since she covers approximately 33.33% of the total bill.
Explanation:The question asks about Alice, Bob, Farhana, and Jamal splitting a pizza bill and figuring out who paid the most. Alice paid 25% (0.25) of the total bill, Bob paid 30% (0.30), Farhana paid a third which is approximately 33.33% (1/3), and Jamal paid 12% (0.12). Given these percentages, it is clear that Farhana paid the most for the pizza because 33.33% is the largest percentage amongst all. Therefore, irrespective of the total bill amount, Farhana ended up paying the highest portion.

The cost of attendance at State College is $19,500 for the first year. Devise a periodic savings plan that will allow you to make small deposits for 5 years at a simple interest rate of 1.5% and save enough to pay for the first year at the college. 15 points!@!!
Answers
[tex]A=P*(1+r*t)[/tex]
Where:
A= total accumulated amount (principal + interest)
P= principal
r= yearly percentage rate
t= number of years
We need to save $19500 for the first year at a college. This is the amount we will have at the account after five years. In our case this is A.
Principal is the amount we need to put into savings to get the total amount needed. In our case this is P.
Yearly percentage rate is the percentage by which our savings increase at the end of a year. In our case this is r.
t is number of years that we are holding our money on the bank account.
To solve this problem we will assume that we are putting same amount each month on the bank account.
We are given:
A=$19500
P=?
r=1.5%
t=5 years
First step is to transform r into decimal number:
[tex]r= \frac{1.5}{100} =0.015[/tex]
Now we get back to our formula and we solve it for P:
[tex]A=P*(1+r*t) \\ P= \frac{A}{1+r*t} [/tex]
We insert numbers and we get our principal:
[tex]P= \frac{19500}{1+0.015*5} \\ P=18139.53[/tex]
We need to put $18139.53 into savings to get required amount after 5 years or 5*12=60months. Assuming that we put same amount each month into savings we need to put
[tex]18139.53 / 60 = 302.33[/tex]
This is our solution for this problem. This is closest to the amount we would need to put in real life. In real life we would earn interest onto interest and our monthly amount would be smaller.

8 1/2 = 8.5 as a decimal.
7 = 7 as a decimal.
2 1/2 = 2.5 as a decimal.
Multiply:
V = 8.5 × 7 × 2.5
V = 59.5 × 2.5
V = 148.75
148.75 = 148 3/4 as a fraction because if you convert 3/4 to a decimal by dividing the numerator by the denominator, it equals 0.75.
ANSWER:
The volume of the book is 148 3/4 inches cubed.

W = 7
H = 2.5
V = 8.5 * 7 * 2.5
V = 148. 75 = 148 3/4
