fredd [130]

Answer:

Carlton thinks that converting metric units is as easy as moving the decimal point

Step-by-step explanation:

When you convert the unit, you move decimal point on your answer from the left to the right or from the right to the left the number of places as per relevant prefix.

Example:

1 meter = 1000 millimeters (1.0 m = 1000.0 mm)
1 milligram = 0.001 grams ( 1.0 mg = 0.001 g)

The Royal Fruit Company produces two types of fruit drinks. The first type is 55% pure fruit juice, and the second type is 80% p

Stolb23 [73]

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:

$A + B = 80$

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

$0.55A + 0.8B = 0.65 * 80$

$0.55A + 0.8B = 52$

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:

$-0.8A -0.8B = -0.8*80$
