What is the area of the shaded sector?
A. 41π units^2
B. 8π units^2
C. 16π units^2
D. 20π units^2
The area of the shaded sector of the circle is 16π units².
How to find the area of a circle?Suppose the circle has radius of 'r' units, then, its area is given as:
[tex]A = \pi \times r^2[/tex]
sq. units
Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:
[tex]\pi \times (\dfrac{d}{2})^2[/tex]
sq. units
We are given that;
θ = r radians
r = 4 units
Now,
To convert radians to degrees, we use the formula:
Degrees = Radians × 180°/π
So,
θ = r × 180°/π
Substituting these values in the formula for area of a sector, we get:
Area of a sector = (r × 180°/π / 360°) × π(4)²
Simplifying, we get:
Area of a sector = r² units²
=16π units².
Therefore, by the area of a circle the answer will be 16π units².

question 1. What will Amanda pay if she rents a truck and drives 45 miles and splits the total cost with two friends? Explain with details?
question 2. find the interpret the slope for the graph.
question 3. how much does it cost to rent a truck for a day?
please answer please I really need the answer asap
Answer:
A) Amanda will pay $47.5
B) 0.5
C) $120
Step-by-step explanation:
A) From the graph given, at 45 miles, the total cost of rentage = $142.50
She now splits this cost with 2 of her friends. Thus each of them will pay;
Amount = 142.5/3 = $47.5
So,Amanda will pay $47.5
B) To find the slope, we will pick two points on the graph and use their respective coordinates to find the slope.
Coordinates we pick are;
(0, 120) and (50, 145)
Thus, slope; m = (y2 - y1)/(x2 - x1)
m = (145 - 120)/(50 - 0)
m = 25/50
m = 0.5
C) The equation for the graph will now be; y = mx + c
Where m is slope and c is y - intercept.
Thus;
y = 0.5x + 120
Coincidentally, c = 120 will be the fixed price of the truck while 0.5x will be the variable cost depending on how many miles are driven.
Thus renting for a day is simply the fixed cost of $120

an angle is 22 degrees smaller than a second angle. the two angles are complementary. what is the measure of the smaller angle?
Let the first angle be x°.
Then the second angle shall be (x - 22)°.
The two angles are complementary. Hence their sum shall be 90°.
First angle + second angle = 90°
=> x° + x° - 22° = 90°
=> 2x° = 112°
=> x° = 56°
Hence first angle = x° = 56°.
Second angle = (x - 22)° = 34°.

Step-by-step explanation:
y = 3x + 10
Let x = 0 and evaluate the expression.
y = 3(0) + 10 = 0 + 10 = 10
Let x = 1 and evaluate the expression.
y = 3(1) + 10 = 3 + 10 = 13
Let x = 2 and evaluate the expression.
y = 3(2) + 10 = 6 + 10 = 16

Answer: It's either 278 or 178
Step-by-step explanation: I didn't know what equation the question wants you to use so for the first equation it showed I did (10^2+24+10+144) and got 278. For the second equation I did 24+10+144 and got 178. Considering it gave you ax+b as an area equation I just added them (same with the other equation). I don't know whether those are correct of not though.

At a toy shop, 45 toys were sold in September. A bonus will be given to workers if they can increase sales by 40% in October. How many toys must the sales team sell in October to receive the bonus?
Answer:
First off, we can find the number that has to be increased by multiplying the original amount by 40%:
45×40%
=45×0.4
=18
We can then add the above amount to the original amount to find the toys they must sell:
45+18
=63
They must sell 63 toys to get the bonus.
Alternatively:
The total percenrage of toys need to be sold to get a bonus with the 40% increase:
=100%+40%
=140%
The amount of toys:
=45×1.4
=63
Therefore the answer is 63.
Hope it helps!

Mr. Hampton asked his students to solve the equation 4x2−5x=9 by using the quadratic formula. Which student set up the formula correctly? Drew Valerie Mishka x=5±−(5)2−4(4)(9)√2(4) x=5±−(5)2−4(4)(−9)√2(4) x=−5±(−5)2−4(4)√−92(4) A. MIshka B. Valerie C. Drew
Answer:
x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)
Step-by-step explanation:
x=5±−(5)2−4(4)(9)√2(4)
x=5±−(5)2−4(4)(−9)√2(4)
x=−5±(−5)2−4(4)√−92(4)
x = -b ± √b² - 4ac / 2a
Given equation:
4x²- 5x = 9
4x² - 5x - 9 = 0
a = 4
b = -5
c = -9
x = -b ± √b² - 4ac / 2a
x = -(-5) ± √(-5)² - (4)(4)(-9) / 2(4)
x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)
The correct formula is
x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)
