Answer:
Step-by-step explanation:
The area of a circular sector with a central angle θ and radius r is given by:
<em>Note</em>: 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:
Answer:
Step-by-step explanation:
Part A
The discount offered is 30%. If the original price of a sweater is $40, then the discount on the sweater is
30/100 × 40 = $12
The cost of the sweater after the discount is
40 - 12 = $28
Part B
The discount on the shirts was 30%. The amount taken off the shirt is
30/100 × 63 = $18.9
The original cost of the three shirts is
63 - 18.9 = $44.1
Since the shirts are of the same price,the original cost of each shirt is
44.1/3 = $14.7
Part C
Each employee gets an additional 10% off the already discounted price. If an employee buys an item with an original price of $40, then the additional amount taken off is
10/100 × 40 = $4
The amount that the employee would pay is
40 - 4 = $36
Answer:
The last option
Step-by-step explanation:
This definitely isn't a parallelogram, so you can knock both of the yes answers out. One of the rules of parallelograms are that if there is 1 right angle then all four need to be right angles, even if the others are supplementary if the right angle rule is not followed then the shape is not a parallelogram.
