Remember that the average or mean is the ratio between the sum of all numbers involve and the total number of items there.
In this case, the total is 28 degrees, and the total number of days is 7, we just have to divide.
[tex]\bar{x}=\frac{28}{7}=4[/tex]Therefore, the average temperature per day is 4 degrees.What would be 2 radians converted into degrees? Need help cant include square units in my answer
REQUIRED:
We are required to convert an angle measure of 2 radians into degrees.
Step-by-step solution;
First thing to note is that the formula for conversion from radians to degrees is an inverse of degrees to radians. The formula for conversion is;
[tex]\begin{gathered} Radians\Rightarrow Degrees: \\ r\times\frac{180}{\pi} \\ \\ Degrees\Rightarrow Radians: \\ d\times\frac{\pi}{180} \end{gathered}[/tex]For the angle given as 2 radians, we now have;
[tex]\begin{gathered} r\times\frac{180}{\pi} \\ \\ =2\times\frac{180}{\pi} \\ \\ =114.591559026 \end{gathered}[/tex]ANSWER:
[tex]2radians=114.59\degree[/tex]1. Solve: 12 + 24 = 6 x 3 = ?
Answer:
9
Step-by-step explanation:
12 + 24 = 36
6 * 3 = 18
36 = 18 = ?
Well, 18 is 1/2 of 36, so the next sequence would be 1/2 of 18, which is 9.
I'm not quite sure that this would be correct, just because I have no more context.

A helicopter hovers 550 feet above a small island. The figure shows that the angle of depression from the helicopter to point p is 43°. How far off the coast, to the nearest foot, is the island? (Round the answer to the nearest whole number.)
The angle of depression and angle P are alternate interior angles, then:
∠P = 43°
By definition:
tan(angle) = opposite/adjacent
In this case,
tan(43°) = 550/d
d = 550/tan(43°)
d = 590 ft

We are to find the future value
The future value can be calculated using
[tex]FV=PV(1+\frac{r}{100\alpha})^{n\alpha}[/tex]From the given information
PV = $4013
r = 4.1
n = 9 years
Since the investment is compounded quarterly then
α = 4
By substituting these values we get

We are asked to determine the area of the given figure. The figure is composed of two semi-circles and a rectangle, therefore, the total area of the figure is:
[tex]A=A_s+A_r+A_s[/tex]The area of the semicircle is given by:
[tex]A_s=\frac{1}{8}\pi D^2[/tex]Where "D" is the diameter. Replacing the values we get:
[tex]A_s=\frac{1}{8}(3.14)(70m)^2[/tex]Solving the operations:
[tex]A_s=1923.25m^2[/tex]Now we determine the area of the rectangle using the following formula:
[tex]A_r=wh[/tex]Where "w" and "h" are the dimensions of the rectangle. Replacing the values we get:
[tex]\begin{gathered} A_r=(98m)(70m) \\ A_r=6860m^2 \end{gathered}[/tex]Now we replace the values in the formula for the total area:
[tex]A=1923.25m^2+6860m^2+1923.25m^2[/tex]Solving the operations:

A linear equation is always of the form:
y = mx + c
Where m = the slope
and c = the intercept
The equation given is y = 2x + 4

First, let's picture the problem
Let's label the angle D as x
Remember that the sum of angles in a quadrilateral is 360
[tex]\begin{gathered} 72^0+94^0+113^0+x=360^{\square} \\ x=81^0 \\ m\angle D=81^0 \end{gathered}[/tex]Velasquez, Miguel, Juan, and Pablo score a total of 36 points in a game of basketball. They score a consecutive even number of points from smallest to greatest in respect to the order of the names mentioned. How many points does Juan score?A6 pointsB12 pointsC8 pointsD10 points
Take into account that the scores are three even consecutive numbers. Being x a missing value we can write:
2x, 2(x+1), 2(x+2), 2(x+3)
where each of the previous expressions corresponds to the score of Velasquez, Migule, Juan and Pablo respectivelly.
Now, due to the sum of all scores are 36 point, we can write:
2x + 2(x+1) + 2(x+2) + 2(x+3) = 36
By applying distribution property left side and by ordering like terms we get:
2x + 2x + 2x + 2x + 2 + 4 + 6 = 36
8x + 12 = 36
Now, by subtracting 12 both sides, simplifying and dividing by 8 we obtain:
8x = 36 - 12
8x = 24
x = 24/8
x = 3
Then, we can replace the previous value into the expression which represents Juan score:
2(x + 2) = 2(3 + 2) = 2(5) = 10
Hence, Juan scored 10 points (option D)
For this problem identify P, FV, I, r, n, and t.
a) P = 180,000cents
b) FV = 298,418cents
c) I = 118,418cents
d) r = 0.003375
e) n = 12
f) t = 15 years
Explanations:a) P is the principal in the given question. The principal can be the amount invested or borrowed.
According to the question, the amount invested is $1,800.00, hence the principal P is $1,800 which is equivalent to 180,000cents to the nearest cents
b) The future value is the amount after 15 years of investing the money. According to the question, Sandra earned a total interest of $1,184.18 after 15 years.
Future value = Principal + Interest
Future value = $1,800.00 + $1,184.18
Future value = $2,984.18
Hence FV to the nearest cent is 298,418cents
c) Given the total interest of $1,184.18
Convert to nearest cents
I = 1,184.18 * 100
I = 118,418cents
d) r is the rate in percentage. From the question the rate in percent is
3 3/8 %
Convert to decimal
[tex]\begin{gathered} r=3\frac{3}{8}\% \\ r=\frac{27}{8}\% \\ r=\frac{27}{800} \\ r=0.03375 \end{gathered}[/tex]e) n is the time of compounding. From the question, we are told that amount invested was compounded monthly. Since there are 12 months in a year, hence the value of n is 12.
f) "t" is the time taken by Sandra to invest $1,800 to earn the given interest. From the question, the time it takes is 15 years. Hence;
t = 15 years

Hi! I have a question and I don't understand it's answer. Could you help me?It's in the attachment below.
To solve this question, we just need to evaluate our set of points in the standard form equation of a Hyperbola, and find the coefficients. This will give to us the equation for our Hyperbola. The standard form is
[tex]\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1[/tex]Let's start with the easier points, the x-intercepts (5, 0) and (-1, 0).
Since this hyperbola has two x-intercepts, we're dealing with a horizontal hyperbola, and the center is the midpoint between the x-intercepts.
[tex]\begin{gathered} \bar{x}=\frac{x_1+x_2}{2}=\frac{-1+5}{2}=2 \\ \bar{y}=\frac{y_1+y_2}{2}=\frac{0+0}{2}=0 \end{gathered}[/tex]The center coordinates are (2, 0), then, our equation is
[tex]\frac{(x-2)^2}{a^2}-\frac{y^2}{b^2}=1[/tex]To find the missing coefficients, we can just substitute the remaining points and solve the system for a and b. Our final equation is

bottom right corner and rotated by an angle of α (see drawing). Find an expression for the
enclosed area A(α) between the two squares with respect to the rotation angle α.
The expression for the area enclosed between the two squares with respect to the rotation angle α is
(α/90)a².
What is a square?A Square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is given as side²
We have,
Side of the square = a
Area of the square = a²
The full angle that can be rotated is 90°.
Now,
The area enclosed if the angle is 90°.
= a²
We can write as,
The area enclosed in terms of the angle.
= (angle rotated / 90) x side²
= (angle rotated / 90) x a²
Now,
The angle rotated is α.
The area enclosed is (α/90)a².
Thus,
The expression for the area enclosed between the two squares with respect to the rotation angle α is
(α/90)a².

when solving a system by graphing, the solution is the intersection point both graphs
so
In this problem
the intersection point is (-2,2)
therefore
the solution is (-2,2)Find the coordinates of the midpoint of HX1H4-1X34324
We need to find the midpoint of a segment HX given the endpoints:
H = (4.5, -4.25) and X = (3.25, -2.75)
where we have written the coordinates (initially in mixed number form) in decimal form for ease of handling operations.
4 1/2 = 4.5
-4 1/4 = -4.25
etc.
Now we apply the formula for the midpoint (in the x and y coordinates separately):
x coordinate of midpoint = (4.5 - 3.25)/2 + 3.25 = 3.875
y coordinate of midpoint = (-2.75 - (-4.25))/2 + (-4.25) = -3.5
So we can write the coordinates of themidpoint as:
(3.875, -3.5) or in mixed number form as: (3 7/8, -3 1/2)
