Step-by-step explanation:
Here, we are to select two options which are correct about the rectangular pyramid.
The area of the base of the pyramid is 24 cm^2 is correct
This is because, mathematically, since we have a rectangular base, the area of the base = length of the base * width of the base = 4 cm * 6 cm = 24 cm^2
The volume of the pyramid is 216 cm^3 is correct
To calculate the volume of the pyramid, what we do is to multiply the area of the base of the pyramid by the height of the pyramid = 24 * 9 = 216 cm^3
If you would like to know which statement is true, you can do this using the following steps:
7.06 minutes < 7.60 minutes
Sandra: <span>7.06 minutes
Joanne: </span><span>7.60 minutes
The correct result would be A. Sandra had the faster time.</span>

Step-by-step explanation:
Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $19 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has a $24 monthly fee and charges an additional $0.08 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal
Answer: Let the number of minutes of calls that will cost the two plans to be equal be x. The first plan has a $19 monthly fee and charges an additional $0.13 for each minute of calls, therefore the total cost in x minutes = $19 + $0.13x
The second plan has a $24 monthly fee and charges an additional $0.08 for each minute of calls, therefore the total cost in x minutes = $24 + $0.08x
For the two plans to be equal, the cost of the first plan should be equal to the cost of the second plan. i.e.:
$19 + $0.13x = $24 + $0.08x
Solving for x:

It would take 100 minutes of calls for the costs of the two plans to be equal
