How many 1/4
gram dosages of medication can be obtained from a container
holding 3/8
gram of the medication?

Answers

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

Given the following data:

Mass of medication = [tex]\frac{1}{4}[/tex] grams.Mass of container = [tex]\frac{3}{8}[/tex] grams.

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

How to calculate the dosages.

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.

A scuba diver is 30 feet below the surface of the water 10 seconds after he entered the water and 120 feet below the surface after 40 seconds. What is the scuba diver's rate of change (include the units)?
Find slope(Rate of Change)

Answers

Answer:

3 feet  per second

Step-by-step explanation:

The rate of change is:

m = the change in depth / the change in time =      (120 - 30) / (40 - 10) =      90 / 30 =      3 feet/second

Take 2 points

Abigail and her mom want to make matching pairs of polka-dotted pajama pants. So, they go to the craft store to pick out fabric. Abigail needs 4 feet of fabric for her pajamas, and her mom needs 6 feet of fabric. But, the store only sells fabric by the yard. If they buy 4 yards of fabric, how many feet will be leftover?

Answers

Answer: 2 feet

Explanation: A yard is 3 feet.
4 feet for Abigail and 6 for her mother makes 10 feet in total.
4 yards x 3 (to convert to feet, every yard is 3 feet, so you multiply) equals 12 feet.
12 - 10 is 2.

How to find the median of 30 37 8

Answers

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.

Suppose y varies directly with x. If y = 3 when x = 2, find y when x = 3.
A *9/2
B *2/3
C *3/2
D *2/9​

Answers

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

The circumference of a circle is 10.4mm.
Find the length of the diameter.
Give your answer rounded to 3 SF.

Answers

Answer:

diameter: 3.31 mm

Explanation:

circumference of circle → πd

using the formula:

10.4 = πd

d = 10.4/π

d = 3.31 mm

Answer:

diameter = 3.31 mm (3 sf)

Step-by-step explanation:

Diameter of a circle (d) = 2r  (where r is the radius)Circumference of a circle = 2[tex]\pi[/tex]r  (where r is the radius)
⇒ circumference = [tex]\pi[/tex]d

Given:
