Find the area of a sector with a central angle of 140° and a diameter of 9.6 cm. Round to the nearest tenth.
Answers
Answer:
[tex]A=28.1\ cm^2[/tex]
Step-by-step explanation:
The area of a circular sector with a central angle θ and radius r is given by:
[tex]\displaystyle A=\frac{1}{2}r^2 \theta[/tex]
Note: The angle must be in radians.
We need to find both the radius and the angle in radians.
Diameter = 9.6 cm
Radius r=Diameter/2=4.8 cm
Angle in radians= Angle in degrees*π / 180
θ = 140*π / 180 = 2.4435 rad
Now we calculate the area:
[tex]\displaystyle A=\frac{1}{2}(4.8)^2 2.4435[/tex]
[tex]\boxed{A=28.1\ cm^2}[/tex]

Select the equation that is the inverse of the given function.
f(x) = x-3/5
• f^-1(x) = 5x + 15
• f^-1(x) = 5x + 3
• f^-1(x) = 3x - 5
• f^-1(x) = - 5/3x
Answers
Answer:
f^-1(x) = 5x + 3Step-by-step explanation:
Given function
f(x) = (x - 3)/5Its inverse is
x = (f^-1(x) - 3)/55x = f^-1(x) - 3f^-1(x) = 5x + 3The second option is correct

Erin can read to chapters of her book in 1.5 hours. If Erin's book has 33 chapters, predict how many hours it will take her to complete her book
pls help
Answers
Answer:
33/2= 16.5
16*1.5= 24.75 24 hrs 45 min
Step-by-step explanation:
It will take 24.75 hours of reading to finish 33 chapters of the book.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given is Erin can read two chapters of her book in 1.5 hours and Erin's book has 33 chapters.
Two chapters of book → 1.5 hours of reading
one chapter of book → (1.5/2) hours of reading
33 chapters of book will be completed in → (1.5/2 x 33) = 24.75 hrs
Therefore, it will take 24.75 hours of reading to finish 33 chapters of the book.

A city taxi driver charges $2 per kilometer and has a starting fee of $9. An Uber driver charges $5 per kilometer, but has no starting fee. At which distance (in kilometers) will the price of taking an Uber be equal to the price of taking a city taxi?
Answers
Answer:
2 tripsStep-by-step explanation:
first, we need to model an expression, the solve, say
let the total amount charged by taxi be y
and let the number of kilometers be x
y=2x+9
given that uber charges $5
then the number of taxi trips that will equal urber charge is
y=2x+9=5
5=2x+9
solving for x we have
2x+9-5=0
2x+4=0
2x=-4
x=-2
x=2 (x cannot be negative)

Look : angle 1 + angle 3 = 180°
because it is a straight line.
Thus ;
[tex]5x + 35 + 4x + 10 = 180[/tex]
Simplification
[tex]9x + 45 = 180[/tex]
Subtract sides 45
[tex]9 x = 180 - 45[/tex]
[tex]9x = 135[/tex]
Divided sides 9
[tex] \frac{9}{9}x = \frac{135}{9} \\ [/tex]
[tex]x = 15[/tex]
So x = 15°
_________________________________
angle 1 = 5x + 35°
angle 1 = 5 ( 15 ) + 35°
angle 1 = 75° + 35°
angle 1 = 110°
_________________________________
angle 1 + angle 2 = 180°
110° + angle 2 = 180°
Subtract sides 110°
angle 2 = 180° - 110°
angle 2 = 70°

Eric is swimming along the surface of the sea. He uses positive numbers to represent elevations above the surface of the sea and negative numbers to represent depths under the surface of the sea. Mark is sitting on the deck of a ship above Eric , and Ariel is diving beneath Eric. Who could be at an elevation of -3 m?
Answers
Answer:
Ariel will be at an elevation of -3 m.
Step-by-step explanation:
There are three persons Eric, Mark and Ariel.
Location of these persons are,
Mark - Sitting at deck (Above the sea level)
Eric - swimming along the surface (At the sea level)
Ariel - diving beneath Eric (Below the sea level)
Since, all the distances above the sea level are measured with positive notation and below the sea level with negative.
Ariel will be at an elevation of -3 m.

how many quarters make 40 dollars
can you work it out with quarters
help me please help me please help me please
Answers
Given problem;
Number of quarters in $40;
To solve this problem;
Convert the dollar value to cents;100cents = $1
In $40, we would have; 40 x 100 = 4000cents
1 quarter = 25 centsSo, divide 4000cents by 25 to obtain the number of quarters in that amount of dollars;
Number of quarters = [tex]\frac{4000}{25}[/tex] = 160
So there are 160 quarters in $40
