Step-by-step explanation:
Answer:
First type of fruit drinks: 48 pints
Second type of fruit drinks: 32 pints
Step-by-step explanation:
Let's call A the amount of first type of fruit drinks. 55% pure fruit juice
Let's call B the amount of second type of fruit drinks. 80% pure fruit juice
The resulting mixture should have 65% pure fruit juice and 80 pints.
Then we know that the total amount of mixture will be:

Then the total amount of pure fruit juice in the mixture will be:


Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -0.8 and add it to the second equation:



+

--------------------------------------



We substitute the value of A into one of the two equations and solve for B.


Answer:
A and C
Step-by-step explanation:
- A right triangle consists of two legs and a hypotenuse.
- To find hypotenuse, we use The Pythagorean Theorem
- The Pythagorean Theorem =

- two legs meet at a 90° angle and the hypotenuse is the longest side
3 - 4 - 5
6 - 8 - 10
7 - 24 - 25
5 - 12 - 13
are some basic right triangle
(about more, look picture)
<em><u>Just use hypotenuse formula :</u></em>
3 x 3 = 9
4 x 3 = 12
5 x 3 = 15
Option C is correct

Option A is correct

But B isn't correct
