Answer:

91

Step-by-step explanation:

91 is what I think makes the most sense

Irrational because it can not be a whole number

Answer:

The distributive property says that when there is a number outside of parenthesis, this means it should be distributed (or multiplied) to the values inside the parenthesis.

So in this situation, 10 x b = 10b

and 10 x 4c = 40 c

so 10(b + 4c) becomes 10b + 40c once the 10 is distributed within the parenthesis.

I hope this helps!

Answer:

They are equivalent expressions because if you use distributive property and multiply 10*b, then multiply 10*4c, you get 10b+40c

Answer:

6.98%

Step-by-step explanation:

To find relative frequency we divide frequency with the total number participants in that age bracket

Total number of participants age 10-19=172.....................given in the table

The frequence for those who ski at age 10-19=12---------------given in table

Relative frequency= 12/172 = 0.0697

Expressed as a percentage= 0.06976×100 =6.98%

Answer:

The correct answer option is 6.98%.

Step-by-step explanation:

We are given the results of a survey which asked  two age groups which summer sport they most preferred.

We are to find the relative frequency of 10-19 year old who preferred to ski.

For that, we will divide the number of kids aged 10-19 years who prefer to ski by the total number of people who prefer to ski and multiply by 100.

Relative frequency = 12/172 * 100 = 6.98%

This problem models a right triangles, where the hypothenuses is the length of the string, and one leg would be 180ft, which is the difference between the total height from the ground and the pole height (186-6=180). Also, the angle in front of the knowing leg is 60.

As, based on all given values, we can apply trigonometric reasons to the hypothenuse, which is L.

[tex]sin60=\frac{180}{L}\\ L=\frac{180}{sin60}\\ L=\frac{180}{\frac{\sqrt{3} }{2} }\\ L=\frac{360}{\sqrt{3}}=\frac{360}{1.7} \approx 211.8ft[/tex]

Answer:

Part A. the x-intercepts are: x=4 and x= -1/4

Part B. The vertex of the graph is going to be a maximum

Part C. y-intercept is y=8

Step-by-step explanation:

We have the following function:

f(x) = −8x^2 + 30x + 8

Part A: What are the x-intercepts (zeros) of the graph of the f(x)?

To find the x-intercepts we have to make y=0 and solve for x. Then:

y = −8x^2 + 30x + 8

0 = −8x^2 + 30x + 8

8x^2 - 30x - 8  = 0

Dividing the whole expression by 8:

x^2 - 15/4x - 1  = 0

Using the quadratic formula we have that:

(x−4)(4x+1)

So the x-intercepts are: x=4 and x= -1/4

Part B.  Is the vertex of the graph of f(x) going to be a maximum or minimum?

The vertex of the graph is going to be a maximum, given that the quadratic term is multiplied by a negative sign.

PArt C. What is the y intercept of the graph?

To calculate the y-intercept we need to make x=0, so:

y = −8(0)^2 + 30(0) + 8 = 8

So the y-intercept is y=8

Answer:

x = k/(y+z)

Step-by-step explanation:

We need to write a general formula to describe the variation: x varies jointly with the inverse of the sum of y and z

it can be written as

x ∝ 1/(y+z)

or can be written as

x = k/(y+z)

where k is the constant of variation introduced when we remove the ∝ sign.

The mean weight of the three reserve players is found by rearranging the formula for calculating the mean, substituting known values, and solving the equation.

Given that the mean weight of all 12 players (nine players + three reserve players) is 188 pounds. Let's denote the missing weight of the three reserve players as 'x', 'y', and 'z'.

The formula to calculate mean is the sum of all the weights divided by the number of players. Here, mean weight equals (9*188 + x + y + z) / 12.

As we know that the mean weight is 188 pounds. We can substitute it back into the formula:
9*188 + x + y + z = 188 * 12.
This simplifies to x + y + z = 188 * 12 - 9 * 188.

We divide by 3 (since we are looking for the mean weight of three players): (x + y + z) / 3 = (188*12 - 9*188) / 3. Thus, the mean weight of the three reserve players can be found by solving this equation.

Answer:

You need 30 total weeks to win at least 65% games

Step-by-step explanation:

Team have played = 20 games

Number of winning games = 3

Let x represents the number of additional weeks.

You have won 3 games per week. Therefore you will win 3x additional games.

We know that 65% = 0.65

Therefore,

3+3x/20+4x = 0.65

By cross multiplication:

3+3x= 0.65(20+4x)

3+3x = 13+2.6x

Combine the like terms:

3x-2.6x = 13-3

0.4x=10

4x/10 =10

4x = 10*10

4x=100

Divide both sides by 4

4x/4 = 100/4

x = 25

since you have already played 5 weeks...you need to play 25+5 = 30 weeks.

Therefore you need 30 total weeks to win at least 65% games....

Answer:

400° F = 204.4° C

Step-by-step explanation:

We are given a temperature 400 degree in Fahrenheit and we are to convert in into another unit that is Centigrade (also known as Celsius).

We know that 0 degree Centigrade is equal to 32 Fahrenheit so we will use the following formula for conversion of units:

(32°F − 32) × 5/9 = 0°C

(400°F − 32) × 5/9 = 204.4° C

A triangle with angles of 30, 60, and 90 degrees is a unique and special type of right triangle known as a 30-60-90 right triangle, which has consistent properties and side ratios in Euclidean geometry.

Yes, a triangle with angles of 30, 60, and 90 degrees is a unique triangle, known as a 30-60-90 right triangle. This classification is based on the fact that in Euclidean geometry, the sum of the angles in any triangle is exactly 180 degrees. Since one of the angles is given as 90 degrees, this indicates it is a right triangle, and the remaining angles must add up to 90 degrees. Given that the other two angles are 30 and 60 degrees, this satisfies the requirement exactly, making it a specific type of right triangle with consistent properties.

For example, the sides of a 30-60-90 triangle are always in the ratio 1:√3:2. The side opposite the 30-degree angle is the shortest; the side opposite the 60-degree angle is √3 times longer; and the hypotenuse, opposite the 90-degree angle, is twice as long as the shortest side. These proportions and the angles create the unique properties of the 30-60-90 triangle, and they can be applied in trigonometric calculations and proofs. This distinct set of angles and side ratios is what makes the 30-60-90 triangle a special and unique case in geometry.

Answer:

To find the value of the y units, u have to multiply any x unit with the first y unit given but not 0

Step-by-step explanation:

The answer is:

The center of the circle is the point (-9,-2) and the circle has a radius of 6 units.

To solve the problem, we need to use the given equation which is in the general form, and then, use it transform it to the standard form in order to find the center of the circle and its radius.

So,

We are given the circle:

[tex]x^{2}+y^{2}+18x+4y+49=0[/tex]

We know that a circle can be written in the following form:

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

Where,

h is the x-coordinate of the center of the circle

k is the y-coordinate of the center of the circle

r is the radius of the circle.

So, to find the center and the radius, we need to perform the following steps:

- Moving the constant to the other side of the equation:

[tex]x^{2}+y^{2}+18x+4y=-49[/tex]

- Grouping the terms (x and y):

[tex]x^{2}+18x+y^{2}+4y=-49[/tex]

- Completing squares for both variables, we have:

We need to sum to each side of the equation the following term:

[tex](\frac{b}{2})^{2}[/tex]

Where, b, for this case, will the coefficients for both terms that have linear variables (x and y)

So, the variable "x", we have:

[tex]x^{2} +18x[/tex]

Where,

[tex]b=18[/tex]

Then,

[tex](\frac{18}{2})^{2}=(9)^{2}=81[/tex]

So, we need to add the number 81 to each side of the circle equation.

Now, for the variable "y", we have:

[tex]y^{2} +4y[/tex]

Where,

[tex]b=4[/tex]

[tex](\frac{4}{2})^{2}=(2)^{2}=4[/tex]

So, we need to add the number 4 to each side of the circle equation.

Therefore, we have:

[tex](x^{2}+18x+81)+(y^{2}+4y+4)=-49+81+4[/tex]

Then, factoring, we have that the expression will be:

[tex](x+9)^{2}+(y+2)^{2}=36[/tex]

- Writing the standard form of the circle:

Now,  from the simplified expression (after factoring), we can write the circle in the standard form:

[tex](x+9)^{2}+(y+2)^{2}=36[/tex]

Is also equal to:

[tex](x-(-9))^{2}+(y-(-2))^{2}=36[/tex]

Where,

[tex]h=-9\\k=-2\\r=\sqrt{36}=6[/tex]

Hence, the center of the circle is the point (-9,-2) and the circle has a radius of 6 units.
