Decide whether each of these sets of data is discrete or continuous.

Sauron [17]

Hey there. Discrete data is usually date which is counted. Continuous data is data that can be measured, and can take any type of value. So for this, a) Continuous, b) Discrete c) Continuous, d) Discrete

Hopefully this should be right! :)

Using the figure to the right, if RSTU is a rhombus, find measure RST.

sammy [17]

Given:

In rhombus RSTU, $m\angle RUV=(10x-23)^\circ$ and $m\angle TUV=(3x+19)^\circ$ .

To find:

The $m\angle RST$ .

Solution:

We know that, diagonals of a rhombus are angle bisector. So,

$m\angle RUV=m\angle TUV$

$(10x-23)^\circ=(3x+19)^\circ$

$10x-23=3x+19$

Isolating variable terms, we get

$10x-3x=23+19$

$7x=42$

Divide both sides by 7.

$x=\dfrac{42}{7}$

$x=6$

Now,

$m\angle RUV=(10x-23)^\circ$

$m\angle RUV=(10(6)-23)^\circ$

$m\angle RUV=(60-23)^\circ$

$m\angle RUV=37^\circ$

And,

$m\angle TUV=(3x+19)^\circ$ .

$m\angle TUV=(3(6)+19)^\circ$

$m\angle TUV=(18+19)^\circ$

$m\angle TUV=37^\circ$

Now,

$m\angle RUT=m\angle RUV+m\angle TUV$

$m\angle RUT=37^\circ+37^\circ$

$m\angle RUT=74^\circ$

We know that opposite angles of a rhombus are equal.

$m\angle RST=m\angle RUT$

$m\angle RST=74^\circ$

Therefore, the measure of angle RST is $74^\circ$ .

A liquid in the lab has a density of 1.24 g/cm3. What is the mass in grams of 254 ml of the liquid

Airida [17]

Answer:

<h2>The answer is 314.96 g</h2>

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of liquid = 254 mL

Density = 1.24 g/cm³

The mass is

mass = 254 × 1.24

We have the final answer as

Hope this helps you
