Answer:
Brand X has to mix 8.4 oz of brand A mixed nuts which contain 35% peanuts and 12.6 oz of brand B mixed nuts which contain 25%, to obtain 21 oz. Bags of mixed nuts that contain 29% peanuts.
Step-by-step explanation:
Hi
We define
, wich means Brand A has 1 oz containing 35% peanuts.
, wich means Brand b has 1 oz containing 25% peanuts.
So we can build an equiation system
(1) 
(2)
, after fixing it a little
(2)
As we can use any method to solve the system, I used a calculator wich thrown the following results 
and 
.
Answer:
35y2+13y−12
=35y2+28y−15y−12
=7y(5y+4)−3(5y+4)
=(7y−3)(5y+4)
Therefore, the possible length and breadth are 7y-3 units and 5y+4 units
X - y = 0.85
x + y = 1
----------------add
2x = 1.85
x = 1.85/2
x = 0.925
x + y = 1
0.925 + y = 1
y = 1 - 0.925
y = 0.075
so ur 2 numbers are : 0.925 and 0.075
Answer:
P(Dᶜ )=0.41
Step-by-step explanation:
In the survey, the event D is the event of people who prefer to flirt directly in person.
Given that P(D)=0.590.
If someone is selected randomly, the probability that the individual prefers to flirt directly in person is 0.590.
If the person does not like to flirt in person, the probability of it will be the complement of event D.
From Probability Theory,
P(D)+P(Dᶜ )=1
0.590+P(Dᶜ )=1
P(Dᶜ )=1-0.590=0.41
The probability that the selected person does not like to flirt in person is 0.41.
When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive. When you multiply two integers with different signs, the result is always negative.
