Answer:

Step-by-step explanation:

Use discramnt formula

$b {}^{2} - 4ac$

Where 6 is a, 11 is b and 9 is c

$11 {}^{2} - 4(6)(9)$

$121 - 216 = - 95$

Since the discramnt is negative, there are no real solutions and it will only produce imaginary solutions

what is the total weight of the italian Sandwhich?write the amount as a fraction in simplest form,meat:0.35,vegie:0.15,sauce:0.0

Olegator [25]

The total weight of the Italian sandwich in its simplest fraction is 3/5.

meat : 0.35 in fraction 35/100
veggies : 0.15 in fraction 15/100
sauce : 0.05 in fraction 5/100
bread : 0.05 in fraction 5/100

Total weight = 35/100 + 15/100 + 5/100 + 5/100
= (35 + 15 + 5 + 5) / 100
= 60/100

To simplify the fraction:

60/100 ⇒ 60 ÷ 10 = 6 ; 100 ÷ 10 = 10 ⇒ 6/10
6/10 ⇒ 6 ÷ 2 = 3 ; 10 ÷ 2 = 5 ⇒ 3/5
