Given that,

The ratio of acid and water is 1 : 5.

A bottle contains 228 ml of the mixture.

To find,

How much water were needed to make this amount of mixture.

Solution,

Let acid is x and water is 5x. ATQ,

x+5x = 228

6x = 228

x = 38

Acid = 38 mL

Water = 5x

= 5(38)

= 190 mL

Hence, 190 mL of water is needed.

Answer:

(x-8) is the factor.

Step-by-step explanation:

The given trinomial is [tex]x^{2}-6x-16[/tex].

We need to find the factor of this trinomial.

[tex]x^{2}-6x-16=x^2-8x+2x-16\\\\=x(x-8)+2(x-8)\\\\=(x+2)(x-8)[/tex]

The factors of [tex]x^{2}-6x-16[/tex] is (x-2) and (x-8).

So, the factor of [tex]x^{2}-6x-16[/tex] is (x-8). Hence, the correct option is (B).

Answer:

$262.5

Step-by-step explanation:

We are told that:

A credit card company charges a 3.5% transfer fee to transfer a balance to a new account.

The transfer fee be for a balance transfer of $7,500 is calculated as:

3.5% × $7500

= 3.5/100 × $7500

= $262.5

The transfer fee for a balance transfer of $7500 is $262.5

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

6v + 18 - 9v = -12

Step 2: Solve for v

Step 3: Check

Plug in v into the original equation to verify it's a solution.

Here we see that -12 does indeed equal -12.

∴ v = 10 is the solution to the equation.

Answer:

:)

Step-by-step explanation:

Part A: To get an equation into standard form to represent the total amount  rented (y) that Marguerite has to pay for renting the truck for x amount of days, we use the formula for the equation of a straight line.

Remember that the equation of a straight line passing through points is ( x_{1} , y_{1} ) and the points ( x_{2} , y_{2} ) is given by

y - y_{1} / x - x_{1} = y - y_{2} / x - x_{2}

Knowing that Marguerite rented a truck at $125 for 2 days, we know if she rents the exact same truck for 5 days, she has to pay a total of $275 for the rent.

This means that the line modeling this situation crosses points at (2, 125) and (5, 275).

The equation modeling the total rent (y) that Marguerite has to pay for renting the truck for x days is given by

y - 125 / x - 2 = 275 - 125 / 5 - 2 = 150 / 3 = 50

But if you are writing the equation in standard form it would be  

50x - y = -25

Part B:

When writing the function using function notation it means you are making y the subject of the formula and then replacing the y with f(x).

If you remember that from part A, we have that the equation for the total rent which is y that Marguerite has to pay for renting the truck for x amount of days is given by

y = 50x + 25.

Writing the equation using the function notation would give us this

f(x) = 50x + 25

Part C:

To graph the function, we name the x-axis the number of days and name the y-axis total rent. The x-axis is numbered using the intervals of 1 while the y-axis is numbered using the intervals of 50.

The points of (2,125) and of (5,275) are marked on the coordinate axis and a straight line is drawn to pass through these two points.

Answer:

205

Step-by-step explanation:

Answer:  2.05 dollars

=================================================

Work Shown:

1 quarter = 25 cents

5 quarters = 125 cents .... multiply both sides by 5

1 dime = 10 cents

8 dimes = 80 cents .... multiply both sides by 8

(5 quarters) + (8 dimes) = (125 cents) + (80 cents) = 205 cents

205 cents = 205/100 = 2.05 dollars

-------------------------

Another way to approach the problem is to compute

5*25 + 8*10 = 205

that's the total number of cents
