Answer:
$0.75
Step-by-step explanation:
Given
Normal price - $3.70
If Hamburger is on sale for 20% off the normal price
The amount that can be saved will be 20% of $3.70
Amount that can be saved = 20/100 * 3.70
Amount that can be saved = 1/5 * 3.70
Amount that can be saved = 3.7/5
Amount that can be saved = 0.75
Hence the Amount that can be saved on $3.70 is $0.75
Let x and y be the 2 parts of 15 ==> x + y=15 (given)
Reciprocal of x and y ==> 1/x +1/y ==> 1/x + 1/y = 3/10 (given)
Let's solve 1/x + 1/y = 3/10 . Common denominator = 10.x.y (reduce to same denominator)
==> (10y+10x)/10xy = 3xy/10xy ==> 10x+10y =3xy
But x+y = 15 , then 10x+10y =150 ==> 150=3xy and xy = 50
Now we have the sum S of the 2 parts that is S = 15 and
their Product = xy =50
Let's use the quadratic equation for S and P==> X² -SX +P =0
Or X² - 15X + 50=0, Solve for X & you will find:
The 1st part of 15 is 10 & the 2nd part is 5
Answer:
x is the price the helmets were sold at.
y is the business expenses.
r is the revenue.
500x - y = r
Step-by-step explanation:
500x - y = r
We multiply x, the price that the helmets were sold at. Then we subtract y, which is the business expenses. After this, we get r, our revenue.
You shouldnt be cheating! what would your guardian say!!!
*edit*
<span>dont even need a protracter b/c there all evenly spaced and a line = 180 so 180 / 3 is 60</span>
F(0)=-3(0-1)
f(0)=-3(-1)
f(0)=3
