At Pizza Pi, 20% of the pizzas made last week had extra cheese. If 50 pizzas had extra cheese, how many pizzas in all were made last week?
Answer:
250 pizzas
Step-by-step explanation:
We can use the formula 50 = 20/100x. We multiply both sides by 100 to get 5000 = 20x. Now, we divide both sides by 20 to get 250 = x. That means 250 pizzas were made last week.

An airplane begins decreasing its altitude as it approaches the runway. At time t=1, the pilot notes that he has an altitude of 30,000 feet. One minute later, his altitude drops to 29,450 feet. One minute after that, his altitude drops to 28,900 feet. Assuming this pattern continues, write a recursive formula for the altitude of the plane A(t) after t minutes.(1 point)
A(t)=30000+550(t−1)
A(t)=A(t−1)−550 for t>1, where A(1)=30000
A(t)=A(t−1)+550 for t>1, where A(1)=30000
A(t)=30000−550(t−1)
Answer: i think A(t)=30000−550(t−1)

A factory uses 3/4 of a barrel of raisins in each batch of granola bars. Yesterday, the factory
used 1 1/2 barrels of raisins. How many batches of granola bars did the factory make
yesterday?
Write your answer as a fraction or as a whole or mixed number.
batches
By solving a simple quotient with the mixed numbers/fractions, we will see that they made 2 batches.
How many batches of granola bars did the factory make yesterday?We know that the factory uses 3/4 of a barrel for a batch of granola bars.
In this case, we know that yesterday they used (1 + 1/2) barrels of raisins, to see how many batches of granola bars they made, we need to take the quotient between the total amount used and the amount needed for a single batch.
N = (1 + 1/2)/(3/4)
The quotient can be written as:
N = (1 + 1/2)*(4/3) = 4/3 + 4/6 = 4/3 + 2/3 = 6/3 = 2
They made 2 batches.

What's the domain and range of the equation d(t)=1/2t+6 do I need to simplify it or what do I need to do?
Step-by-step explanation:
dt=12t+6
Step 1: Add (-1)/2t to both sides.
dt+−12t=12t+6+−12t
dt+−12t=6
Step 2: Factor out variable t.
t(2d−12)=6
Step 3: Divide both sides by (2d-1)/2.
t(2d−12)2d−12=62d−12
t=12/2d−1
Answer:
t=12/2d−1
Noah orders an extra-large pizza. It costs $12.49 for the pizza plus $1.50 for each topping. He orders an extra-large pizza with toppings that costs a total of dollars. Select all of the equations representing the relationship between the number of toppings and the pizza's total cost with toppings.
a. 12.49 + t = d
b.12.49 + 1.50d = d
c. 12.49 + 1.50 = t
d. 12.49 = d +1.50t
e. t = [tex]\frac{d-12.49}{1.5}[/tex]
f. t = d - [tex]\frac{12.49}{1.5}[/tex]
The equation to represent the given situation is 12.49+1.50d=t. Therefore, options B and E are the correct answers.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Noah orders an extra-large pizza. It costs $12.49 for the pizza plus $1.50 for each topping.
Let t be total money and d be the number of toppings.
So, the equation is 12.49+1.50d=t
1.50d=t-12.49
d=(t-12.49)/1.50
Therefore, options B and E are the correct answers.

Answer:k = 2/3
Step-by-step explanation:
When a variable y directly relates to another variable x, we can say:
y=kx
Given the equation, we can say
3y=2x
y= 2x/3
Putting the value of y from above discussion
kx = 2x/3
x is being cancelled on both sides of equation

On a team 5 girls and 2 boys scored a total of 41 points. The difference between the number of points scored by the 5 girls and the number of points scored by the
2 boys is 29. Each girl scored the same number of points and each boy scored the same number of points. Find the number of points scored by each girl and each
boy
Each girl scored points
Step-by-step explanation:
Let x be the number of points the 5 girls scored.
=> 41 - x is the number of points the 2 boys scored.
We have x + 29 = 41 - x or x - 29 = 41 - x.
=> 2x = 12 or 2x = 70
=> x = 6 or x = 35
We reject x = 6 as 6 is not a multiple of 5. (Each girl would have scored 1.2 points which is absurb)
So x = 35, each girl scored 35/5 = 7 points.
=> 41 - (35) = 6, each boy scored 6/2 = 3 points.

Question
Under ideal conditions, the population of a certain species doubles every nine years. If the population starts
with 100 individuals, which of the following expressions would give the population of the species t years after
the start, assuming that the population is living under ideal conditions?
Answer: 100 x 2^ t/9
Step-by-step explanation:
The initial population of 100 that doubles in 9 years, gives the
expression for population as; [tex]\underline{ P = 100 \cdot e^{0.077 \cdot t}}[/tex].
How can the expression for the population be found?Given parameters are;
The time it takes the population to double = 9 years
The initial population count = 100
Required:
The expression that gives the population after t years.
Solution:
The population as a function of time can be expressed as an
exponential function as follows;
[tex]P = \mathbf{P_0 \cdot e^{c \cdot t}}[/tex]
At the start, t = 0, P = 100, we have;
[tex]100 = \mathbf{ P_0 \times e^{c \times 0} }= P_0[/tex]
Therefore;
P₀ = 100
After 9 years, we have;
P = 2·P₀
Therefore;
[tex]2 = \mathbf{ e^{c \times 9}}[/tex]
ln(2) = 9·c
[tex]c = \dfrac{ln(2)}{9} \approx 0.077[/tex]
The function that gives the population is therefore;
[tex]\underline{ P = 100 \cdot e^{0.077 \cdot t}}[/tex]Learn more about exponential functions here:
