Suppose 15 quarts of a solution that is 35% antifreeze is mixed with 5 quarts of a solution that is 72% antifreeze. 1.how many q
Finger [1]

Answer:

1. 8.85 quarts

2. 44.25%

Step-by-step explanation:

In 15 quarts of a solution with percentage of antifreeze = 35%

Amount of antifreeze = 35% × 15

                                    = 0.35 × 15

                                    = 5.25 quarts

that solution is mixed with 5 quarts of a solution with percentage of antifreeze = 72%

Amount of antifreeze = 72% × 5

                                    = 0.72 × 5

                                    = 3.6 quarts

Total amount of mixture = 15 quarts + 5 quarts = 20 quarts

1. Now we will calculate the total amount of antifreeze in the resulting mixture.

= 5.25 + 3.6 = 8.85 quarts

2. The percentage of the resulting mixture is antifreeze

= \frac{8.85}{20}\times 100

= 44.25%

1. total amount of antifreeze is 8.85 quarts

2. the percentage of antifreeze is 44.25%

The correct expression for a number which is 9 times as big as the number obtained after p has been increased
defon

Answer:

9(p + 4)

Step-by-step explanation:

One of the unknown variable is p.

First of all, we know that the number is 9 times as big (multiplication) as the new number obtained through the addition of four to p i.e (p + 4).

Translating the word problem into an algebraic expression, we have;

9 * (p + 4) = 9(p + 4)

Simplifying further, we have;

9p + 36

Determine if the rates $168 rasied for washing 24 cars and $280 rasied for washing 40 cars are equivalent
Mariana [72]

We are given : $168 raised for washing 24 cars and $280 raised for washing 40 cars.

We know the rate formula.

Rate = Total amount ÷ Total numbers.

Let us find value of each rate for  the given problem.

Rate 1: Total amount ÷ Total numbers = $168 ÷ 24 = $7.

Rate 2: Total amount ÷ Total numbers = $280 ÷ 40 = $7.

We can clearly see that Rate 1 is equal to Rate 2, that is $7.

So, we can say rates are equivalent.
