how many quarts of pure antifreeze must be added to 6 quarts of a 40% antifreeze solution to obtain a 60% antifreeze solution
lora16 [44]

Answer:

3 quarts

Step-by-step explanation:

First, find how many quarts of antifreeze is in the mixture.

0.4 x 6 = 2.4

Now, make it into a fraction by putting the antifreeze amount over the rest so:

2.4/6

Now add + a at the end of the numerator and bottom to make:

2.4 + a/ 6 + a.

Now, turn the percentage you want to strengthen or weaken the mixture into a percentage. So, 3/5.

Now, make it an expression by adding = 3/5 at the end of the equation.

2.4 + a/ 6 + a = 3/5

Now, use cross multiplication.

12 + 5a = 18 + 3a

Now, solve the equation.

12 + 5a = 18 + 3a

-3a. -3a

12 + 2a = 18

-12. -12

2a = 6

/2. /2

a = 3.

Therefore, the answer is 3 quarts.

What is the recursive rule for an=3n+5
inessss [21]

Answer:

Option d is correct.

Step-by-step explanation:

We have given a formula a_n=3n+5

We will put different values of n so, as to get a_n

from the given formula

When n =1  we get

a_1=3(1)+5=8

When n=2 we get

a_2=3(2)+5=11

When n=3 we get

a_3=3(3)+5=14

We can see that next term is 3 more than the previous term

Hence, a_1=8;a_n=a_{n-1}+3

Therefore, Option d is correct.

If a^3-1/a^3=4 then what is the value of a-1/a ??
natita [175]

Answer:

1 or -0.5±1.9365i

Step-by-step explanation:

We know that x^{3} - y^{3} = (x-y) ^{3} +3xy(x-y)

So plug in x=a and y=1/a, (a-1/a)^3+3*a*1/a*(a-1/a)=4

Let a-1/a=k, k^3+3k=4, k=1 or a complex conjugate -0.5±1.9365i

That's the answer.
