Answer:

9/2

Step-by-step explanation:

Direct variation is

y = kx where k is the constant of variation

Substitute into the equation to find k

y=3 and x=2

3 = k*2

Solve for k

3/2 = k

y = 3/2 x

We know x =3

y = 3/2 * 3

y = 9/2

Answer:

A

Step-by-step explanation:

given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 3 when x = 2 , then

3 = 2x ( divide both sides by 2 )

[tex]\frac{3}{2}[/tex] = k

y = [tex]\frac{3}{2}[/tex] x ← equation of variation

When x = 3 , then

y = [tex]\frac{3}{2}[/tex] × 3 = [tex]\frac{9}{2}[/tex] → A

Answer:

[tex]7\sqrt{3} +12\sqrt{2}[/tex]

Step-by-step explanation:

[tex]\sqrt{12} -\sqrt{18} +3\sqrt{50} +\sqrt{75}[/tex]

[tex]\implies \sqrt{4\times3} -\sqrt{9\times2} +3\sqrt{25\times2} +\sqrt{25\times3}[/tex]

[tex]\implies \sqrt{4}\sqrt{3} -\sqrt{9}\sqrt{2} +3\sqrt{25}\sqrt{2} +\sqrt{25}\sqrt{3}[/tex]

[tex]\implies 2\sqrt{3} -3\sqrt{2} +3(5)\sqrt{2} +5\sqrt{3}[/tex]

[tex]\implies 2\sqrt{3} -3\sqrt{2} +15\sqrt{2} +5\sqrt{3}[/tex]

[tex]\implies 2\sqrt{3} +5\sqrt{3} +15\sqrt{2} -3\sqrt{2}[/tex]

[tex]\implies 7\sqrt{3} +12\sqrt{2}[/tex]

Step-by-step explanation:

Answer:

10/3 = 3 1/3

Step-by-step explanation:

If 5/6 is one fourth (1/4) of a number,

multiply 5/6 by 4 to find the number:

5/6 x 4 = 10/3 = 3 1/3

The quantity of dosages of medication that can be obtained from the container is 1.5 dosages.

Given the following data:

To calculate the quantity of these dosages of medication that can be obtained from the container:

In this exercise, you're required to determine the amount of dosages of medication can be obtained from the container. Thus, we would divide the given mass of container by the mass of medication as follows:

[tex]Quantity = \frac{\frac{3}{8}}{\frac{1}{4}}[/tex]

Simplifying further, we have:

[tex]Quantity = \frac{3}{8} \times 4\\\\Quantity = \frac{12}{8} \\\\Quantity = \frac{3}{2}[/tex]

Quantity = 1.5 dosages.

Answer:

to find the median, divide the odd number by 2 and round it up

for even numbers, only divide by 2.

Average the numbers with the number in the next highest position.

You have a median.

In this case, the median is 30.

The median of the numbers 30, 37, and 8 is 30.

To find the median of a set of numbers, you first need to arrange the numbers in either ascending or descending order and then determine the middle value.

Given the numbers: 30, 37, 8

Arrange the numbers in ascending order:

8, 30, 37

Determine the middle value:

Since there are three numbers, the middle value is the second number, which is 30.
