Answer:

270 mL of pure alcohol is needed.

Step-by-step explanation:

In 540 mL of the mixture, you have 540*10% = 54 mL of pure alcohol.

If you add x mL pure alcohol, then you have (540 + x) mL solution, in it there is (54 + x) mL of pure alcohol

so (54 + x)/(540 + x) = 40%

Then

54 + x = 0.4(540 + x)

54 + x = 216 + 0.4 x

0.6x = 216 - 54 = 162

x = 162/0.6 = 270 mL

Answer:

The correct answer is, F-1(x) = 5(x-3)/3

Step-by-step explanation:

The inverse of given function f(x) = 3-x/5 would be equal to 3(x - 5)/5

Suppose that the given function is [tex]f:X\rightarrow Y[/tex]Then if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is ;

[tex]f^{-1}: Y \rightarrow X[/tex]

We have been given a function of x as ; 3-x/5.

To find the inverse we will just switch x and function of x with each other.

That means we have;

x = 5/3  f(x) + 5

5/3 f(x) = x - 5

f(x) = 3(x - 5)/5

Hilary trip is an illustration of a scalene triangle

The triangle that represents Hilary's trip can be classified by the side lengths.

From the figure, the side lengths of the triangles are:

919 miles, 586 miles and 1212 miles

The lengths are not equal.

Triangles that do not have equal side lengths are scalene triangles

Hence, the triangle that represents Hilary's trip is a scalene triangle

To do this, we simply calculate the perimeter of the triangle.

So, we have:

P = 919 miles + 586 miles + 1212 miles

P = 2717 miles

Hence, Hilary completed 2717 miles

Answer:

3.55

Step-by-step explanation:

This is simply combining like terms.

First, lets evaluate the terms separately.

x = 8 - (-2.25)

x = 8 + 2.25 (Negative signs cancel out)

x = 10.25 (Combine like terms)

y = 6 - 4.2 - (-4.9)

y = 6 - 4.2 + 4.9 (Negative signs cancel out)

y = 6.7 (Combine like terms)

Now, lets plug in these values to x - y.

(10.25)  - (6.7)

3.55

The value of x - y is equal to 3.55.

Answer:

28%

Step-by-step explanation:

Let number of children be 2x, then number of adults be 3x

Total number is 5x

Let number of children under 10 be 7y, number of children be 3y,

then total number of children is 10y

so 2x = 10y, x = 5y, y/x = 1/5

younger children = children under 10, number is 7y

so the % is 7y/5x = 7/5 * y/x = 7/5 * 1/5 = 7/25 = 28/100 = 28%

Answer:

4 mL

Step-by-step explanation:

Multiply .25 by 2 because you are dispensing it twice a day.

.25 x 2 = .5, so you dispense .5 mL a day.

Now, multiply .5 mL a day x 8 days.

.5 x 8 = 4

Therefore, you should dispense 4 mL.

Answer:

The answer should be A. [tex]x \in (-\infty,\, 2)[/tex].

Step-by-step explanation:

Start with the second inequality, which is more straightforward than the first. Add [tex]3[/tex] to both sides of this equation to separate [tex]x[/tex] from the numbers:

[tex]x - 3 + 3 \le -1 + 3[/tex]. The direction of the inequality sign shall stay the same.

[tex]x \le 2[/tex].

On the other hand, simplifying the first inequality takes a bit more work. Start by dividing both sides by [tex](-3)[/tex]. However, keep in mind that dividing or multiplying both sides of an inequality with a negative number will invert the direction of the inequality sign. For example, the left-hand side of an inequality might have been greater than the right-hand side. When both sides are multiplied with a number less than zero, the new left-hand side would become smaller than the new right-hand side.

Because [tex](-3)\![/tex] is a negative number, dividing both sides of the first inequality inequality by [tex](-3)[/tex] will turn the "greater-than" sign into a "less-than" sign.

The inequality used to be:

[tex]-3\, (x + 2) > 15[/tex].

After dividing both sides by the negative number [tex](-3)[/tex], it becomes:

[tex]\displaystyle \frac{(-3)\, (x + 2 )}{(-3)} < \frac{15}{(-3)}[/tex].

[tex]\displaystyle (x + 2) < -5[/tex].

[tex]x < -7[/tex].

The question connected the two original inequalities with "or". Therefore, the conditions will be satisfied as long as either of at least one of the two inequalities is true. Note, that [tex]x < 2[/tex] is true whenever [tex]x <-7[/tex] is true. Therefore, any real number that is smaller than [tex]2[/tex] will meet the requirements- not just those that are smaller than [tex](-7)[/tex].

The corresponding interval will be [tex](-\infty,\, 2)[/tex].

Answer:

x = 12

Step-by-step explanation:

ΔABC is a right triangle, therefore we can use Pythagoras' Theorem to find the value of x.

Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Therefore,

Substitute these values into the equation and solve for x:

⇒ x² + 16² = 20²

⇒ x² + 256 = 400

⇒ x² = 400 - 256

⇒ x² = 144

⇒ x = √(144)

⇒ x = ±12

As length is positive, x = 12 units (only)

The equation that shows the number of minutes, x, it will take for the tank and the container to have the same amount of water will be 340 - 6x = 6x.

Based on the information given, the equation that shows the number of minutes, x, it will take for the tank and the container to have the same amount of water will be 340 - 6x = 6x. Therefore, the number of minutes will be:

340 - 6x = 6x

Collect like terms

340 = 6x + 6x

340 = 12x

x = 340/12

x = 28.33 minutes.

In 28.33 minutes, they'll have the same content.
