Answer:
430
Step-by-step explanation:
To find the area, use the area for a parallelogram formula:
A = bh, where A is the area, b is the length of the base, and c is the height of the parallelogram.
Next, substitute the values of the base and height:
A = 20in. * 21.5 in.
Finally, simplify the multiplication:
A = 430
I'll help on 12. You know that 5*5 is 25. therefore what times 5 equals 20?
The answer is 110.
The 55 degree angle is related to arc B. The measure of arc B is double the measure of the angle. So, arc B covers 55*2=110 degrees.
For plan A it will only take five minutes to amount to $20.50
Plan B will need 30 min to cost the same as plan A $20.50
