Hello.

Taking a look at our screenshot provided, we can conclude that we need to find the missing angle degree out of 90 degrees, as we are dealing with a right angle.

Let's set this up as an Algebraic formula and solve for the variable;
5x + 15 + 50 = 90

First, let's combine like-terms (15 and 50).

5x + 65 = 90

Now, isolate our variable by subtracting 65 from each side of the equation.

90 - 65 = 25
65 - 65 = 0

5x = 25

Now, divide both sides by 5 to solve for x, our missing angle degree.

x = 5

Your answer is A.) 5

I hope this helps!

Answer: The dependent variable is discrete.

Step-by-step explanation:

There are different types of variables. Variables can be classified into two main groups: qualitative and quantitative.

Qualitative variables are those who represent attributes. For example, flowers of 3 different colors: yellow, orange and blue. Also, when they haven’t an order or a hierarchy, they are called nominal, as in the previous flowers's example. When they have a hierarchy associated, they are called ordinal (you can distinguish a natural order), for example: small, medium, large.

Quantitative variables are those that represent quantities, and they can be discrete or continuous. A variable is discrete when only certain finite values are possible. This variables are used to represent counts, like the in the example: number of colds within a winter season, or for example, number of students in a class, number of plants per acre, etc.

On the other hand, when a variable is continuous, infinite values can be found between two values. They are measure in continuous scales. For example, the plant’s height: it could be take any continuous values, like 10.3 cm, 15 cm, 17.99 cm.

In summary, in the present problem the response variable is quantitative and discrete, because it is countable and finite, and only some values are possible: positive integers.

a carton contains 1 3/4 quarts of ice cream. One serving is a 1/5 of a quart. How many servings are in the carton?

tatuchka [14]

Answer: 8 3/4

Explanation: Well in order to solve this equation, you must make the denominators equivalent. A common factor between 4 and 5 is 20. But since we multiplied the denominators, we have to do the same to the numerators. 3 x 5 = 15. 1 x 4 = 4. Our new fractions are now 1 15/20 and 4/20. Now that we have made our denominators equivalent, we can divide. 1 15/20 divided by 4/20 is 8 15/20. But we are not done yet, after we must simplify the fraction. Which would be 8 3/4.

When a number is added to 1/5 of itself, the result is 24. The equation that models this problem is n+ 1/5+n = 24. What is the

kap26 [50]

Answer:

n = 20

Step-by-step explanation:

If we call "a number" n, the equation modelling that statment is:

$\frac{1}{5}n+n=24$

Now, if we have one whole thing - 5/5 - and add 1/5 of that thing, we'll have a total of 6/5 of it. By that same logic, 1/5 of n + 5/5 of n = 6/5 of n. We can write that fact as

$\frac{6}{5}n=24$

So, we slice this number n up into 5 equal parts, we take 6 of those slices, and that gets us a total value of 24. What would the value of just 1 slice - a single fifth of n - be? Well, we'd just need to divide 24 by 6 to find that

$\frac{1}{5}n=24\div6=4$

And if 1/5 of something is 4, that whole thing, 5/5, must be 5 × 4, or 20! Writing that step out in symbols, we have

$\frac{1}{5} n\times5=4\times5=20=n$

So n = 20.

Nina [5.8K]

Answer:

The area of the pendant is 12 square centimeters.

Step-by-step explanation:

The question is incomplete, so the complete question is below:

Giselle a pendant on her necklace that is the shape of a regular hexagon. On the pendant, there are lines for the center of each vertex that divided it into congruent triangles. Each triangle has an area of 2 square centimeters.

$What\ is\ the\ area\ of\ the\ pendant?$

Now, to get the area of pendant.

In the hexagonal pendant there are congruent triangles that are divided from the lines of the center of each vertex.

Each triangle's area = 2 square centimeters.

As, we see in the figure below there are six congruent triangles in the hexagonal pendant.

Hence, the number of triangles = 6.

So, to get the area of pendant we multiply each triangle's area by the number of triangles:

$2\ cm^2\times 6\\\\=12\ cm^2.$

Therefore, the area of the pendant is 12 square centimeters.
