If the mass of a material is 49 grams and the volume of the material is 7 cm^3, what would the density of the material be?

inysia [295]

The equation for density is:
$density = \frac{mass}{volume}$

To help you remember - my teacher told us to remember "We <span>♡ density," and the heart stands for </span> $\frac{m}{v}$ , or $\frac{mass}{volume}$ . Cheesy, but it works!<span>
</span>
Back to the problem:
We know the mass if 49g and the volume is 7 $cm^{3}$ , so plug these values into the equation for density:
$density = \frac{mass}{volume}\\
density = \frac{49\:g}{7\:cm^{3}} \\
density = 7\:g/cm^{3}$

Answer: The density is 7 g/ $cm^{3}$

Doctor's order: Infuse 50mg of Amphotericin B in 250ml NS over 4 hr 15 min; Drop factor : 12gtt/ml. What flow rate ( ml/hr) will

svlad2 [7]

Answer:

59 ml/hr

Step-by-step explanation:

Amount of solution = 250 ml

Flow rate = 250 ÷ 4.25 hrs = 58.82352941176 ml/hr

since answer is required in ml/hr and not gtt/hr,

Therefore answer = 59 ml/hr to the nearest flow rate.

Does the following equation determine y to be a function of x? y square=x+3

Phantasy [73]

Answer:

∴ y² = x + 3 is not a function

Step-by-step explanation:

* Lets explain how to solve the problem

- The definition of the function is every input (x) has only one

output (y)

- Ex:

# y = x + 1 where x ∈ R , is a function because every x has only

one value of y

# y² = x where x ∈ R , is not a function because y = ±√x, then one

x has two values of y

* Lets solve the problem

∵ y² = x + 3

- Find y by taking √ for both sides

∴ y = ± √(x + 3)

- That means y = √(x + 3) and y = - √(x + 3)

∵ (x + 3) must be greater than or equal zero because there is no

square root for negative number

∴ x + 3 ≥ 0 ⇒ subtract 3 from both sides

∴ x ≥ -3

∴ x must be any number greater than or equal -3

- Let x = 0

∴ y = √(0 + 3) = √3 and y = - √(0 + 3) = -√3

∴ x = 0 has two values of y ⇒ y = √3 and y = -√3

- Any value of x greater than or equal 3 will have two values of y

∴ y² = x + 3 is not a function

Aldo made a shirt using 1/5 meters of yellow fabric and 2/3 meters of red fabric. How many meters of fabric did he use in all? W

Tomtit [17]

Answer:

Aldo's shirt was made of 13/15 meters of fabric.

Step-by-step explanation:

We need to add these fractions. However, in order to do so, we need to find the LCM, which in this case, is 15.

1/5 + 2/3 =

3/15 + 10/15 =

13/15

This fraction is also written in simplest form. Therefore, Aldo's shirt was made of 13/15 meters of fabric.

Hope this helps! :D
