How many quarts of pute antifreeze must be added to 3 quarts of a 20% antifreeze solution to obtain a 40% antifreeze solution

Answers

Answer 1

Answer: 0.6

Explanation: I am going to break them into steps, so that you can understand them more clearly.

Step 1: Find how much the amount of water is needed:

0.4(3 quarts + x quarts) = (0.6 quarts + x)

Step 2: Find how much the quarts is divided by 0.6:

1.2 + 0.4x = 0.6 + x

Step 3: each quart is equal to 1 therefore:

x = 1 quart - which is 0.6

What happens to y=x when the y-intercept is changed

Answers

Answer:

When the y-intercept of a line is changed, the line will shift up or down along the y-axis. The slope of the line will remain the same, but the point at which the line crosses the y-axis will change. This means that the position of the line on the graph will change, but the overall shape of the line will stay the same. For example, if the y-intercept of the line y=x is changed from (0,0) to (0,5), the line will shift up by 5 units and will now be represented by the equation y=x+5. This will cause the line to intersect the y-axis at the point (0,5) instead of (0,0).

If the value of a = 5 and c = √21  then the value of b = 2i, b = -2i.

What is meant by simplest radical form?Simply said, simplifying a radical eliminates the need for further square, cube, fourth, etc. roots to be found. This is known as expressing in the simplest radical form. In the denominator of a fraction, it also means eliminating any radicals. The top and bottom of a fraction are said to be in its simplest form if they only share the number one. For the top and bottom to remain whole numbers, you cannot divide them further. Additionally, lowest terms, or simple form, may be used. Take the fraction, as an example.The formula goes a² + b² = c², where a and b are legs of the triangle (the non hypotenuse sides), and c is the hypotenuse (the side opposite to the right angle).

In this problem, we have one leg and the hypotenuse.

Let the equation be a² + b² = c²

substitute the values in the above equation, we get

5² +b² = (√21)²

25+b²=21

Move 25 to the right side

b² = -4

For x² = f(a) the solutions are [tex]$x=\sqrt{f(a)},-\sqrt{f(a)}$[/tex]

[tex]$$b=\sqrt{-4}, b=-\sqrt{-4}$$[/tex]

simplifying the above equation, we get

[tex]& \sqrt{-4}=2 i \\[/tex]

[tex]& -\sqrt{-4}=-2 i \\[/tex]

b = 2i, b = -2i

Therefore, the value of b = 2i, b = -2i.

The additional amount Ahmad will spend if Ahmad will spend at most $34 on gifts. So far, he has spent $21 is c = 13.

What is inequality?

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.

Given:

Ahmad will spend at most $34 on gifts,

He spent = $21,

c = additional amount

The total amount he can spend now = total amount - he spent

c = 34 - 21

Mr. Rooks' bank pays 4-% interest per year. He has $17,000 in the bank. How much interest would he receive in 3 years?

Answers

Mr. Rooks would receive $2,040 in interest in 3 years.

The interest rate is given as 4%, which means that for every $100 Mr. Rooks has in the bank, he will receive $4 in interest per year.

To find the total interest Mr. Rooks will receive in 3 years, we need to multiply the annual interest rate by the number of years, and then multiply that result by the amount of money Mr. Rooks has in the bank.

In this case, the calculation would be as follows:

Annual interest rate × number of years × amount in the bank = total interest

(4 / 100) × 3 × $17,000 = $2,040

Therefore, Mr. Rooks would receive $2,040 in interest in 3 years.

Range is:

y ∈ [-5, 3), the lowest point is included as part of graph, the highest value is excluded as open circle..

This is a function as it passes the vertical line test.

Question 26

26)  Domain:   [-3, 7]

       Range:  [-1, 5]

Step-by-step explanation:

Definitions

An open circle indicates the value is not included in the interval.A closed circle indicates the value is included in the interval.An arrow shows that the function continues indefinitely in that direction.

Interval notation

( or ) : Use parentheses to indicate that the endpoint is excluded.[ or ] : Use square brackets to indicate that the endpoint is included.

The domain is the set of all possible input values (x-values).

The range is the set of all possible output values (y-values).

Question 25

From inspection of the graph, the endpoints of the continuous curve are:

(-6, -3) and (6, 3)

As the endpoints are open circles, the values are excluded from the domain and range.

Therefore, the domain in interval notation is:

Domain:  (-6, 6)

The smallest y-value is y = -5 and the greatest y-value is y = 3.

Therefore, the range in interval notation is:

Range:  [-5, 3)

Question 26

The graph is a conic section (ellipse) and therefore it is not a function.

The smallest x-value is x = -3 and the greatest x-value is x = 7.

The smallest y-value is y = -1 and the greatest y-value is y = 5.

Therefore, the domain and range in interval notation are:

What compounded amount would he earn he chooses to invest his savings in Big Sky Bank? What compounded amount would he earn if he chooses to invest his savings in Valley Bank?

Answers

The compounded amount earned in Big Sky Bank is $40,365.00.

The compounded amount earned in Valley Bank is $13,248.24.

What is compound interest?

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = 10% of 60,000

P = 6000

t = 10 years

Big sky Bank:

r = 20%

n = 2 (semiannually)

A = 6000 [tex](1 + 0.1)^{20}[/tex]

A = 6000 x [tex]1.01^{20}[/tex]

A = $40,365.00

Valley Bank:

r = 8%

n = 4 (quarterly)

A = 6000 [tex](1 + 0.02)^{40}[/tex]

A = 6000 x [tex]1.02^{40}[/tex]

A = $13,248.24

Thus,

Big Sky Bank compounded amount is $40,365.00.

Valley Bank compounded amount is $13,248.24.
