Answer:
Step-by-step explanation:
Let
x ----> the number of first class seats
y ----> the number of economy class seats
we know that
An aircraft has a maximum of 30 first class seats
so
An aircraft has a maximum of 220 economy seats
A flight will be cancelled if the money taken for the seats is less than $28,800.
so
therefore
Three inequalities that represent the situation are
Answer:
a. 120
b. -120
c. -120
d. -120
e. 120
Step-by-step explanation:
The amount of - will influence whether the value is positive or negative. Odd number of - is always negative. Even number of - is always positive. Hope this helped :)
Answer:
The radius of the can, rounded to the nearest hundredth, is 530.66.
Step-by-step explanation:
We want to do the reverse of the formula for <em>V</em>, which is pi(r)^2(h).
to isolate r.
Let's start by writing an equivalent equation to V = 
<em>h</em> by solving for r
![\sqrt[]{\frac{V * \pi }{h} } = r](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%5Cfrac%7BV%20%2A%20%5Cpi%20%7D%7Bh%7D%20%7D%20%3D%20r)
Now, substitute and solve for r
1014 * 3.14 / 6 = 530.66
