Answer:
f(3) = 11
Step-by-step explanation:
f (x)=3x+ 2
Let x= 3
f (3) =3*3+ 2
= 9+2
= 11
Answer:
78.5398 cm^2
Step-by-step explanation:
r = 1/2*d => d = 10 cm
r = 5
A = pi*r^2
= pi*5^2 => 3.1415*5^2
=> 78.5398
Answer:
6
Step-by-step explanation:
Substitute 1/4 with 8a. 8/4=2
Next, Substitute 10 for 0.5. 10/2=5
Finally, find the sum
(2-1)+5

The equation in term of p that models the above experience is:
2p + 10 = 0.8p + 20.
<h3>
What is an equation?</h3>
Any statement that models or captures the factors of a problem where in an equal sign is present to equate two of the factors or expressions therein is called an equation.
<h3>How do we form the above equation?</h3>
- Everyday pizza production is equal to p.
- Brick oven use fees are $10 per day.
- Ingredients for brick oven pizza cost $2 per pizza.
- $20 a day is the cost of using an electric oven.
- Pizzas baked in an electric oven cost $0.8 per pizza in ingredients.
- If an electric oven is used, the total cost of making a pizza falls by $1, including the cost of the ingredients.
Total cost of baking p pizzas with brick oven = A = p(cost of one pizza) + cost of baking = p(2) + 10 (in dollars).
Total cost of baking p pizzas with electric oven = B = p(cost of one pizza) + cost of baking = p(0.8) + 20 (in dollars).
B = A - 1 (as using electric oven saves $1 per day, as given)
Thus, we get:
2p + 10 = 0.8p + 20
