So in conclusion, 52 pizzas made costs $52 from 52*1=52. The total cost he makes adds up to $75 which is $75+$52=$127.
The solution is the interval b is in ]11.3, infinity[
Answer:
x=1
Step-by-step explanation:
To solve this question we will have to open the bracket first
So let's solve the question
5(2x-8)+15=-15
Bracket first
10x-40+15=-15
We will have to solve the question further
10x-25=-15
Add 25 to both sides
10x=10
Let's make x the subject of formula by dividing both sides by 10
x=1
Therefore x is 1
Answer:
The question gives you V0 as 220, so plug that in first.
h=-16t2+220t.
Then it says to find the time (solve for t), when the height is 400 ft. Plug 500 ft in as h and solve for t.
500=-16t2+220t.
To solve this, set the quadratic equal to 0 by subtracting 500 from both sides (0=-16t2+220t-500) and use the quadratic formula!

adult=a
children's =500-a
17.95×a+12.95×(500-a)=7355
17.95a+6475-12.95a=7355
5a=880
a=176
