ANSWER

108°

EXPLANATION

The measure of each interior angle of a regular polygon is given by

[tex] \theta = \frac{(n - 2) \times 180}{n} [/tex]

where n refers to the number of sides of the polygon.

From the question we have n=5 in this case.

We substitute to obtain;

[tex]\theta = \frac{(5 - 2) \times 180}{5} [/tex]

[tex]\theta = \frac{3\times 36}{1} [/tex]

This simplifies to:

[tex]\theta = 108 \degree[/tex]

Hence each interior angles of a regular polygon with 5 - sides is 108°

v=9 x 4 x 4=144cm

m=1267.2g

p=1267.2/144

p=8.8 g/cm^3

Answer:

8.8

Step-by-step explanation:

Density = Mass / Volume

Volume = 9 × 4 × 4  = 144

Mass = 1267.2

Density = 1267.2 / 144 = 8.8

Answer:

l = 65 – 15d; discrete

Step-by-step explanation:

15 is the centimeters he cuts off every day, you have to multiply that by D that´s the nomber of days, in order to calculate how much baguette does he have left.

If 4 days have passed, the anser would be 5 centimeters:

I=65- 15(4)= 65-60= 5

Answer:

[tex]l=65-15d[/tex]; discrete.

Step-by-step explanation:

Let d represent number of days.

We have been given that for lunch every afternoon, Diep cuts 15 centimeters of bread for his  sandwich. The length of loaf cut in d days would be [tex]15d[/tex].

Diep bought a baguette loaf of bread 65 centimeters long. The length of loaf of bread after d days would be initial length minus amount of loaf cut in d days that is:

[tex]65-15d[/tex]

Since [tex]l[/tex] represents length of bread, so our equation would be: [tex]l=65-15d[/tex]

Therefore, the expression [tex]l=65-15d[/tex] represents the given scenario.

The variable d represents number of days and days cannot be fractional. We can take only whole number of days, therefore, the graph of the equation would be discrete.

The square root of f(x) is ±(x + 12) and the square root of g(x) is not defined.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable).

f(x) = x^2 + 24x + 144

f(x) = x^2 + 2(12)x + 12^2

f(x) = (x + 12)^2

Square root of f(x) is ±(x + 12)

g(x) = x^3 - 216

g(x) = (x - 6)(x^2 + 6x + 36)

Here, (x^2 + 6x + 36) does not have real roots hence it is not possible to find the square root of g(x).

Final answer:

To solve the equation 4x = -4r + 2d for x, isolate x by performing the same mathematical operations on both sides of the equation.

Explanation:

To solve the equation 4x = -4r + 2d for x, we need to isolate x on one side of the equation. We can do this by performing the same mathematical operations on both sides of the equation. Let's start by moving the terms containing r and d to the other side:

4x + 4r - 2d = 0

Next, we can factor out the common factor of 4:

4(x + r - 0.5d) = 0

Finally, we divide both sides of the equation by 4 to solve for x:

x + r - 0.5d = 0

The solution for x is x = -r + 0.5d.

ANSWER

201.06 square units.

EXPLANATION

The area of a circle is calculated using the formula,

[tex]Area = \pi \: {r}^{2} [/tex]

The given circle has radius, r=8 units.

We substitute the radius into the formula to obtain:

[tex]Area = \pi \times {8}^{2} [/tex]

The exact area is 64π square units.

When we substitute π=3.14, we get,

Area=201.06 units square.

To show Lin's elevation at 3:00 p.m on a graph, mark a point below her starting altitude at 2:00 p.m, given that she was climbing downwards. The exact placement will depend on her descent rate, for which we have no data.

The question refers to Lin climbing downwards in the period from 2:00 p.m. to 3:00 p.m. In order to plot Lin's movement on a graph, we need to define the vertical axis as her altitude and the horizontal axis as time. Since Lin was moving downward, her altitude at 3:00 p.m. should be less than her altitude at 2:00 p.m.

For example, if she started at an altitude of 4,000 meters at 2:00 p.m., when adding a point to the graph at 3:00 p.m., it should be below the 4,000-meter altitude point, since Lin was descending. The exact point will depend on the speed of her descent, which we don't have information on, but it would be somewhere below the starting point.

It's similar to the thrown rock example where the rock rises and then falls. Lin, like the rock, started at a higher point (instead of airborne, she was high on a cliff or a hill), but then moved downwards, decreasing her altitude over time.

#SPJ12

The point is placed at -50 feet to represent a possible elevation halfway between 0 feet and -100 feet. However, it is important to note that her actual elevation could be anywhere within this range.

Assuming Lin started climbing from an elevation of 0 feet at 2:00 p.m., she could have reached a negative elevation at 3:00 p.m. This is because the graph shows that she was descending at a constant rate.

To determine her possible elevation, we need to consider the following:

The slope of the graph represents the rate of change in elevation. A negative slope indicates that Lin is descending.

The y-intercept of the graph represents Lin's elevation at 2:00 p.m. Since she started at 0 feet, the y-intercept is 0.

The time interval from 2:00 p.m. to 3:00 p.m. is one hour.

Using this information, we can determine that Lin's elevation at 3:00 p.m. could be anywhere from 0 feet to -100 feet. This is because the slope indicates that she is descending at a rate of -100 feet per hour.

14 + 7 + 10 = 31 marbles total

7/31 = 0.23 or 23%

The probability of drawing a black marble from a bag containing 14 gray, 7 black, and 10 white marbles is 7/31, which, as a decimal rounded to the nearest hundredth, is 0.23.

The theoretical probability of drawing a black marble from a bag containing 14 gray, 7 black, and 10 white marbles can be calculated by dividing the number of black marbles by the total number of marbles in the bag.

To find the total number of marbles, we add up the counts for each color: 14 gray + 7 black + 10 white = 31 marbles in total.

Next, we calculate the probability by taking the number of black marbles and dividing it by the total number of marbles: Probability = (Number of black marbles) / (Total number of marbles) = 7 / 31.

Converting that probability into a decimal gives us approximately 0.2258. However, rounding this to the nearest hundredth, as asked in the question, gives us 0.23. So, the probability of drawing a black marble is 0.23.

Answer:

[tex]\frac32 \pi[/tex]

Step-by-step explanation:

If you realize that the sin is actually the y coordinate of a (unit) circle when you travel around it, you will know that it is -1 when you are 3 quarters round, assuming you started at (1,0).

The circumference is measured in radians, where one round is 2π.

So 3/4 of 2π is 3/2 π.

In degrees, the answer is 3/4 of 360°, which is 270°.

Answer:

of the number is X, 16 = 1 + (2/10)×X - 8

Answer:

16 = [tex]\frac{6x}{5}[/tex] - 8

Step-by-step explanation:

Topic: One Unkown equation, mixed numbers

first we have to establish our variables, we only have one so we call

x = "a number"

and we start building our one unknown equation part by part by reading

"Sixteen is the same" means in math that "x ="

"one and two tenths"  1 [tex]^{2/10}[/tex]

this means we have (remember how to sum fractions?)

1 + 2 / 10 = 10/10 + 2/10 = 12/10 = 6/5

so " one and two tenths times a number added to negative 8" become [tex]\frac{6x}{5}[/tex] + (-8)

so we have our equation

16 = [tex]\frac{6x}{5}[/tex]  + (-8) or 16 = [tex]\frac{6x}{5}[/tex]  - 8

Answer:

a. 84 students

b. 12

Step-by-step explanation:

a.

From the information given, we see that 7 out of 12 practice every day. Now we want to know how many (let it equal x) would we expect to practice everyday given there are total 144 martial artists?

we set up a ratio and cross multiply and solve for x:

[tex]\frac{7}{12}=\frac{x}{144}\\7*144=12*x\\1008=12x\\x=\frac{1008}{12}=84[/tex]

So 84 students practice everyday

b.

The sample size is a "proportion" of the whole population. Here, there are a total of 144 martial artists. And we took 12 of them to figure out how many practice everyday (from these 12). So , clearly, the sample size is 12

Step-by-step explanation:

We are to find out what percentage of 700 is 14.

Assuming [tex] x [/tex] to be the percent of 700 which is 14, we can write it as:

[tex] \frac { x } { 100 } \times 700 = 14 [/tex]

[tex] \frac { x } {100} = \frac {14} {700} [/tex]

[tex] \frac { x } { 1 0 0 } = 0.02 [/tex]

[tex]x=0.02 \times 100[/tex]

[tex]x=2[/tex]

Therefore, 14 is 2% of 700.
