Answer:

4

Step-by-step explanation:

Given :

10 grams of 15% sugar syrup;

25 grams of 10% sugar syrup

Therefore,

(10grams * (15/100)) + (25 grams * (10/100))

(10 * 0.15) + (25 * 0.1)

1.5 + 2.5

= 4 grams

One canned juice drink is 25% orange juice another is 10% orangw juice. How many liters of each should be mixed together in orde
Vsevolod [243]

Answer:

There should be 10 l of 25% orange juice and 5 l of 10% orange juice.

Step-by-step explanation:

Let the amount of the 25% orange juice be "x", while the amount of the 10% one be "y". The sum of these must be equal to 15 l, therefore:

x + y = 15

The sum of the concentration of juice on each can must be equal to the final product, therefore:

25\%*x + 10\%*y = 15*20\%\\0.25*x + 0.1*y = 3

We can now solve the system of equations as shown below:

\left \{ ({{x + y=15})*(-0.1) \atop {0.25*x + 0.1*y=3}} \right. \\\left \{ {{-0.1*x - 0.1*y=-1.5} \atop {0.25*x + 0.1*y=3}} \right. \\-0.1*x + 0.25*x = 3 - 1.5\\0.15*x = 1.5\\x = \frac{1.5}{0.15} = 10\\y = 15 - x = 15 - 10 = 5

There should be 10 l of 25% orange juice and 5 l of 10% orange juice.

WILL GIVE BRAINLIEST!! The yearly population of a city with a 3% yearly growth rate and an initial population of 30,000 can be m
Vesnalui [34]

1, 3, 5

The reasonable domain has a minimum value.

The reasonable range has a minimum value of 30,000.

The reasonable range has an implied, but unknown, maximum value.

Step-by-step explanation:

1. Years cannot be anything below 0.

2. The domain includes 0 because the answer can be the initial value.

3. 30,000 is the initial value and is the minimum solution.

4. The range has a minimal of 30,000.

5. Logically, we know city populations cant be numbers like a billion but we prove that mathematically.

Pythagorean theorem - please help
Artist 52 [7]

answer:

x = 4\sqrt{2} or 5.6568

step-by-step explanation:

  • know the formula and plug in

formula: a^2 + b^2 = c^2

  • now plug in what we have
  • whatever the RIGHT ANGLE points to is the HYPOTENUSE or c
  • the other two sides are the "legs" or a and b

a^2 + b^2 = c^2

7^2 + b^2 = 9^2

49 + b^2 = 81

b^2 = 32

b = 4\sqrt{2}

  • in this case, b would be used as x

x = 4\sqrt{2} or 5.6568 (exact value)
