a. The lightbulb uses the energy of 960 W or 9.60 kW.
Step-by-step explanation:
Step 1:
To determine the energy used by the appliances we need to understand the equation

To determine the energy used, we multiply the power of the appliance with the amount of time it has been used for.
Step 2:
The lightbulb has a power of 60 W and is used for a period of 16 hours.
The energy used by the lightbulb
W = 0.96 kW.
The toaster oven has a power of 1,500 W and is used for 0.75 hours.
The energy used by the toaster oven
W = 1.125 kW.

Answer: Susan’s favorite food is not pizza.
Step-by-step explanation: a counterexample is an example that shows the statement is false. So if most of the 9th graders in your school do not like pizza, then pizza would not be their favorite food.
Answer: C
Step-by-step explanation: simply apply the distributive property to each half of the expression to be left with terms that can be combined.
(8x + 16y)/2 = 4x + 8y
4(x - y) = 4x - 4y
(4x + 8y) + (4x - 4y) = 4x + 4x + 8y - 4y
= 8x + 4y => C
I would use a proportion for the Fred's Fouls part. Use the closest point to 12 possible, which is (15, 69.5).
Set up the proportion like so:
15/69.5 = 12/x
Now cross multiply.
15x = 834
Now divide both sides by 15 to get x by itself.
x = 55.6
Fred's Fouls will charge $55.60 for 12 wings.
Now plug in 12 as x for the Carlie's Chicken part and solve for f(12).
f(12) = 3.75(12) +10
f(12) = 45 +10
f(12) = 55
Carlie's Chicken will charge $55 for 12 wings.
